Abstract

A redirect system is provided which is operable to redirect information over a network (1610). This information is associated with a compressed MP3 audio file which is initially transmitted through the network from a source (1612) to a user PC (1600). The user PC (1600) will then play the information and, upon playing the information, embedded information within the audio file will be detected by an application program (1604). This will cause a browser (1602) to launch and route the embedded information to an intermediate node (1620). This information will be matched with information in a database (1624), which information provides routing information to a producer location (1614). This is transmitted back to the user PC (1600) which will then effect a connection with the producer (1614) to either view in the simple case a web page and, in the more complex case, actually transmit information from the database (1624) through the user PC (1600) to the producer (1614) to provide a customized communication in the form of a customized web page.

METHOD AND APPARATUS FOR EMBEDDING ROUTING INFORMATION TO A REMOTE WEB SITE IN AN AUDIO/VIDEO TRACK

TECHNICAL FIELD OF THE INVENTION

This invention is related to a method of computer control, and particularly for automatically directing a web browser application on the computer to retrieve and display information in response to an analog signal.

CROSS REFERENCE TO RELATED APPLICATION

This application is a Continuation-In-Part of pending U.S. Patent Application Serial No. 09/151,530 and entitled, "METHOD FOR CONTROLLING COMPUTERS THROUGH A RADIO/TELEVISION COMMUNICATION HUB" (Atty Dkt No. PHLY- 24,398) filed on September 11, 1998, and is related to pending U.S. Patent Application

Serial No. 09/151,471 entitled, "METHOD FOR INTERFACING SCANNED PRODUCT INFORMATION WITH A SOURCE FOR THE PRODUCT OVER A GLOBAL NETWORK" (Atty Dkt No. PHLY-24,397) filed on September 11, 1998, and related to

U.S. Patent Application Serial No. entitled, "METHOD AND APPARATUS FOR CONTROLLING A USER' S COMPUTER FROM A REMOTE LOCATION" (Atty

Dkt No. PHLY-24,703) filed of equal date with this application. 2 BACKGROUND OF THE INVENTION

With the growing numbers of computer users connecting to the "Internet," many companies are seeking the substantial commercial opportunities presented by such a large user base. For example, one technology which exists allows a television ("TV") signal to trigger a computer response in which the consumer will be guided to a personalized web page. The source ofthe triggering signal may be a TV, video tape recorder, or radio. For example, if a viewer is watching a TV program in which an advertiser offers viewer voting, the advertiser may transmit a unique signal within the television signal which controls a program known as a "browser" on the viewer's computer to automatically display the advertiser's web page. The viewer then simply makes a selection which is then transmitted back to the advertiser.

In order to provide the viewer with the capability of responding to a wide variety of companies using this technology, a database of company information and Uniform Resource Locator ("URL") codes is necessarily maintained in the viewer's computer, requiring continuous updates. URLs are short strings of data that identify resources on the Internet: documents, images, downloadable files, services, electronic mailboxes, and other resources. URLs make resources available under a variety of naming schemes and access methods such as HTTP, FTP, and Internet mail, addressable in the same simple way. URLs reduce the tedium of "login to this server, then issue this magic command ..." down to a single click. The Internet uses URLs to specify the location of files on other servers. A URL includes the type of resource being accessed (e.g., Web, gopher, FTP), the address ofthe server, and the location ofthe file. The URL can point to any file on any networked computer. Current technology requires the viewer to perform periodic updates to obtain the most current URL database. This aspect ofthe current technology is cumbersome since the update process requires downloading information to the viewer's computer. Moreover, the likelihood for error in performing the update, and the necessity of redoing the update in the event of a later computer crash, further complicates the process. Additionally, current technologies are limited in the number of companies which may be stored in the database. This is a significant limitation since world-wide access presented by the Internet and the increasing number of companies connecting to perform on-line commerce necessitates a large database.

SUMMARY OF THE INVENTION

The present invention disclosed and claimed herein comprises a method and apparatus for effecting a connection between a user's node on a network and a destination node on a network with an audio program. The audio program is played at the user's node wherein the audio program has embedded therein a unique code. The unique code is detected at the user's node during the playing ofthe audio program and, in response to the detection thereof, information regarding the unique code is transmitted over the network to an intermediate node on the network. At the intermediate node, this received unique code is compared with a database of unique codes having associated routing information therewith. The routing information defines the location on the network of a plurality of destination nodes. Since there is a correlation between each unique code stored in the database and one or more ofthe destination nodes, a match between the received unique code and a unique code in the database defines corresponding routing information. This routing information is then utilized to cause the destination node and the user node to be connected over the network such that the destination node can then transmit information to the user node.

In other aspects ofthe present invention, the user node is connected to the destination node by first transmitting back to the user node the routing information determined to be stored in the database and corresponding to the received unique code. The user node then utilizes this received routing information to effect a connection to the destination node from the user node. The destination node, in response to being connected to the user node via the routing information, is then operable to transfer information to the user's node.

In a yet further aspect ofthe present invention, the user's node includes the user ID information that uniquely identifies the user node. The database at the intermediate node further includes a stored profile which is associated therein with the user ID information with the user ID information ofthe user node. When information is transmitted to the intermediate node regarding the unique code over the network, the user ID information is also transmitted therewith to the intermediate node. During the matching operation, user profile information associated with the user ID information is then extracted and transmitted back to the user's node as an appendage to the routing information transmitted thereto. This user ID information will then be relayed to the destination node, the destination node then utilizing this user LO information in a predetermined manner.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to FIGURE 1 , there is illustrated a block diagram of a system for controlling a personal computer ("PC") 112 via an audio tone transmitted over a wireless system utilizing a TV. In the embodiment illustrated in FIGURE 1, there is provided a transmission station 101 and a receive station 117 that are connected via a communication link 108. The transmission station 101 is comprised of a television program source 104, which is operable to generate a program in the form of a broadcast signal comprised of video and audio. This is transmitted via conventional techniques along channels in the appropriate f equencies. The program source is input to a mixing device 106, which mixing device is operable to mix in an audio signal. This audio signal is derived from an audio source 100 which comprises a coded audio signal which is then modulated onto a carrier which is combined with the television program source 104. This signal combining can be done at the audio level, or it can even be done at the RF level in the form of a different carrier. However, the preferred method is to merely sum the audio signal from the modulator 102 into the audio channel ofthe program that is generated by the television program source 104. The output thereof is provided from the mixing device 106 in the form of broadcast signal to an antenna 107, which transmits the information over the communication link 108 to an antenna 109 on the receive side.

On the receive side ofthe system, a conventional receiver 110, such as a television is provided. This television provides a speaker output which provides the user with an audible signal. This is typically associated with the program. However, the receiver 110 in the disclosed embodiment, also provides an audio output jack, this being the type RCA jack. This jack is utilized to provide an audio output signal on a line 113 which is represented by an audio signal 111. This line 113 provides all ofthe audio that is received over the communication link 108 to the PC 112 in the audio input port on the PC 112. However, it should be understood that, although a direct connection is illustrated from the receiver 110 to the PC 112, there actually could be a microphone pickup at the PC 112 which could pick the audio signal up. In the disclosed embodiment the audio signal generated by the advertiser data input device 100 is audible to the human ear and, therefore, can be heard by the user. Therefore, no special filters are needed to provide this audio to the PC 112. The PC 112 is operable to run programs thereon which typically are stored in a program file area 116. These programs can be any type of programs such as word processing programs, application programs, etc. In the disclosed embodiment, the program that is utilized in the system is what is referred to as a "browser." The PC 112 runs a browser program to facilitate the access of information on the network, for example, a global communication network known as the "Internet" or the World- Wide- Web ("Web"). The browser is a hypertext-linked application used for accessing information. Hypertext is a term used to describe a particular organization of information within a data processing system, and its presentation to a user. It exploits the computer's ability to link together information from a wide variety of sources to provide the user with the ability to explore a particular topic. The traditional style of presentation used in books employs an organization ofthe information which is imposed upon it by limitations ofthe medium, namely fixed sized, sequential paper pages. Hypertext systems, however, use a large number of units of text or other types of data such as image information, graphical information, video information, or sound information, which can vary in size. A collection of such units of information is termed a hypertext document, or where the hypertext documents employ information other than text, hypermedia documents. Multimedia communications may use the Hypertext Transfer Protocol ("HTTP"), and files or formatted data may use the Hypertext Markup Language ("HTML"). This formatting language provides for a mingling of text, graphics, sound, video, and hypertext links by "tagging" a text document using

HTML. Data encoded using HTML is often referred to as an "HTML document," an "HTML page," or a "home page." These documents and other Internet resources may be accessed across the network by means of a network addressing scheme which uses a locator referred to as a Uniform Resource Locator ("URL"), for example, "http://www.digital.com."

The Internet is one ofthe most utilized networks for interconnecting distributed computer systems and allows users of these computer systems to exchange data all over the world. Connected to the Internet are many private networks, for example, corporate or commercial networks. Standard protocols, such as the Transport Control Protocol ("TCP") and the Internet Protocol ("IP") provide a convenient method for communicating across these diverse networks. These protocols dictate how data are formatted and communicated.

As a characteristic ofthe Internet, the protocols are layered in an LP stack. At higher levels ofthe IP stack, such as the application layer (where HTTP is employed), the user information is more readily visible, while at lower levels, such as the network level (where TCP/IP are used), the data can merely be observed as packets or a stream of rapidly moving digital signals. Superimposed on the Internet is a standard protocol interface for accessing Web resources, such servers, files, Web pages, mail messages, and the like. One way that

Web resources can be accessed is by browsers made by Netscape® and Microsoft Internet Explorer®.

Referring again now to FIGURE 1 , the user can load this program with the appropriate keystrokes such that a browser window will be displayed on a display 118. In one embodiment, the user can run the browser program on the PC 112 such that the browser window is displayed on the display 118. While watching a preferred program, the user can also view display 118. When an audio signal is received by the receiver 110 and the encoded information is contained therein that was input thereto by the advertiser, the PC 112 will then perform a number of operations. The first operation, according to the disclosed embodiment, is to extract the audio information within the received audio signal in the form of digital data, and then transmit this digital data to a defined location on the global communication network via a modem connection 114. This connection will be described hereinbelow. This information will be relayed to a proprietary location and the instructions sent back to the PC 112 as to the location ofthe advertiser associated with the code, and the PC 112 will then effect a communication link to that location such that the user can view on the display 118 information that the advertiser, by the fact of putting the tone onto the broadcast channel, desires the viewer to view. This information can be in the form of interactive programs, data files, etc. In one example, when an advertisement appears on the television, the tone can be generated and then additional data displayed on the display 118. Additionally, a streaming video program could be played on the PC received over the network, which streaming video program is actually longer than the advertising segment on the broadcast. Another example would be a sports game that would broadcast the tone in order to allow a user access to information that is not available over the broadcast network, such as additional statistics associated with the sports program, etc. By utilizing the system described herein with respect to the disclosed embodiment of FIGURE 1, an advertiser is allowed the ability to control a user's PC 112 through the use of tones embedded within a program audio signal. As will descried hereinbelow, the disclosed embodiment utilizes particular routing information stored in the PC 112 which allows the encoded information in the received audio signal to route this information to a desired location on the network and then allow other routing information to be returned to the PC 112 for control thereof to route the PC 112 to the appropriate location associated with that code.

Referring now to FIGURE 2, there is illustrated a computer 204, similar to computer 112, connected to display information on display 118. The computer 204 comprises an internal audio or "sound" card 206 for receiving the transmitted audio signal through receive antenna 109 and receiver 110. The sound card 206 typically contains analog-to-digital circuitry for converting the analog audio signal into a digital signal. The digital signal may then be more easily manipulated by software programs. The receiver 110 separates the audio signal from the video signal. A special trigger signal located within the transmitted advertiser audio signal triggers proprietary software running on the computer 204 which launches a communication application, in this particular embodiment, the web browser application located on the PC 204. Coded advertiser information contained within the audio signal is then extracted and appended with the address of a proprietary server located on the communication network. The remote server address is in the form of a URL. This appended data, in addition to other control codes, is inserted directly into the web browser application for automatic routing to the communication network. The web browser running on PC 204, and communicating to the network with a through an internal modem 208, in this embodiment, transmits the advertiser information to the remote server. The remote server cross-references the advertiser product information to the address ofthe advertiser server located on the network. The address ofthe advertiser server is routed back through the PC 204 web browser to the advertiser server. The advertiser product information is returned to PC 204 to be presented to the viewer on display 118. In this particular embodiment, the particular advertiser product information displayed is contained within the advertiser's web page 212. As mentioned above, the audio signal is audible to the human ear. Therefore the audio signal, as emitted from the TV speakers, may be input to the sound 12 card 206 via a microphone. Furthermore, the audio signal need not be a real-time broadcast, but may be on video tapes, CDs, DVD, or other media which may be displayed at a later date. With the imminent implementation of high definition digital television, the audio signal output from the TV may also be digital. Therefore, direct input into a sound card for A/D purposes may not be necessary, but alternative interfacing techniques to accommodate digital-to-digital signal formats would apply.

Referring now to FIGURE 3, there is illustrated a source PC 302, similar to PCs 204 and 112, connected to a global communication network 306 through an interface 304. In this embodiment, the audio signal 111 is received by PC 302 through its sound card 206. The audio signal 111 comprises a trigger signal which triggers proprietary software into launching a web browser application residing on the PC 302. The audio signal 111 also comprises advertiser product information which is extracted and appended with URL information of an Advertiser Reference Server ("ARS") 308. The ARS 308 is a system disposed on the network that is defined as the location to which data in the audio signal 111 is to be routed. As such, data in the audio signal 111 will always be routed to the ARS 308, since a URL is unique on the network system. Connected to the ARS 308 is a database 310 of product codes and associated manufacturer URLs. The database 310 undergoes a continual update process which is transparent to the user. As companies sign-on, e.g., subscribe, to this technology, manufacturer and product information is added to the database 310 without interrupting operation ofthe source PC 302 with frequent updates. When the advertiser server address URL is obtained from the ARS database 310, it and the request for the particular advertiser product information is automatically routed back through the web browser on PC 302, over to the respective advertiser server for retrieval ofthe advertiser product information to the PC 302. It should be noted that although the disclosed invention discusses a global communication network, the system is also applicable to LANs, WANs, and peer-to-peer network configurations. It should be noted that the disclosed architecture is not limited to a single source PC 302, but may comprise a plurality of source PCs, e.g., PC 300 and PC 303. Moreover, a plurality of ARS 308 systems and advertiser servers 312 maybe implemented, e.g., ARS 314, and advertiser server A 316, respectively. The information transactions, in general, which occur between the networked systems of this embodiment, over the communication network, are the following. The web browser running on source PC 302 transmits a message packet to the ARS 308 over Path "A." The ARS 308 decodes the message packet and performs a cross-reference function with product information extracted from the received message packet to obtain the address of an advertiser server 312. A new message packet is assembled comprising the advertiser server 312 address, and sent back to the source PC 302 over Path "B." A "handoff ' operation is performed whereby the source PC 302 browser simply reroutes the information on to the advertiser server 312 over Path "C," with the appropriate source and destination address appended. The advertiser server 312 receives and decodes the message packet. The request-for-advertiser-product-information is extracted and the advertiser 312 retrieves the requested information from its database for transmission back to the source PC 302 over Path "D." The source PC 302 then processes the information, i.e., for display to the viewer. The optional Path "E" is discussed hereinbelow. It should be noted that the disclosed methods are not limited to only browser communication applications, but may accommodate, with sufficient modifications by one skilled in the art, other communication applications used to transmit information over the Internet or communication network.

Referring now to FIGURE 4a, the message packet 400 sent from the source PC 302 to ARS 308 via Path "A" comprises several fields. One field comprises the URL ofthe ARS 308 which indicates where the message packet is to be sent. Another field comprises the advertiser product code or other information derived from the audio signal 111, and any additional overhead information required for a given transaction. The product code provides a link to the address ofthe advertiser server 312, located in the database 310. Yet another field comprises the network address ofthe source PC 302. In general, network transmissions are effected in packets of information, each packet providing a destination address, a source address, and data. These packets vary depending upon the network transmission protocol utilized for communication. Although the protocols utilized in the disclosed embodiment are of a conventional protocol suite commonly known as TCP/TP, it should be understood that any protocols providing the similar basic functions can be used, with the primary requirement that a browser can forward the routing information to the desired URL in response to keystrokes being input to a PC. However, it should be understood that any protocol can be used, with the primary requirement that a browser can forward the product information to the desired URL in response to keystrokes being input to a PC. Within the context of this disclosure, "message packet" shall refer to and comprise the destination URL, product information, and source address, even though more than a single packet must be transmitted to effect such a transmission.

Upon receipt ofthe message packet 400 from source PC 302, ARS 308 processes the information in accordance with instructions embedded in the overhead information. The ARS 308 specifically will extract the product code information from the received packet 400 and, once extracted, will then decode this product code information. Once decoded, this information is then compared with data contained within the ARS advertiser database

310 to determine if there is a "hit." If there is no "hit" indicating a match, then information is returned to the browser indicating such. If there is a "hit," a packet 402 is assembled which comprises the address ofthe source PC 302, and information instructing the source PC 302 as to how to access, directly in a "handoff operation, another location on the network, that of an advertiser server 312. This type of construction is relatively conventional with browsers such as Netscape® and Microsoft Internet Explorer® and, rather than displaying information from the ARS 308, the source PC 302 can then access the advertiser server 312. The ARS 308 transmits the packet 402 back to source PC 302 over Path "B." Referring now to FIGURE 4b, the message packet 402 comprises the address of the source PC 302, the URL ofthe advertiser server 312 embedded within instructional code, and the URL ofthe ARS 308.

Upon receipt ofthe message packet 402 by the source PC 302, the message packet 402 is disassembled to obtain pertinent routing information for assembly of a new message packet 404. The web browser running on source PC 302 is now directed to obtain, over Path "C," the product information relevant to the particular advertiser server 312 location information embedded in message packet 404. Referring now to FIGURE 4c, the message packet 404 for this transaction comprises the URL ofthe advertiser server 312, the request- for-product-information data, and the address ofthe source PC 302. Upon receipt ofthe message packet 404 from source PC 302, advertiser server 312 disassembles the message packet 404 to obtain the request-for-product-information data. The advertiser server 312 then retrieves the particular product information from its database, and transmits it over Path "D" back to the source PC 302. Referring now to FIGURE 4d, the message packet 406 for this particular transaction comprises the address ofthe source

PC 302, the requested information, and the URL ofthe advertiser server 312.

Optionally, the ARS 308 may make a direct request for product information over Path "E" to advertiser server 312. In this mode, the ARS 308 sends information to the advertiser server 312 instructing it to contact the source PC 302. This, however, is unconventional and requires more complex software control. The message packet 408 for this transaction is illustrated in FIGURE 4e, which comprises the URL ofthe advertiser server 312, the request-for-product-information data, and the address ofthe source PC 302. Since product information is not being returned to the ARS 308, but directly to the source PC 302, the message packet 408 requires the return address to be that ofthe source PC 302. The product information is then passed directly to PC 302 over Path "D."

Referring now to FIGURE 5, the method for detecting and obtaining product information is as follows. In decision block 500, a proprietary application running resident on a source computer PC 302 (similar to PC 204) monitors the audio input for a special trigger signal. Upon detection ofthe trigger signal, data following the trigger signal is decoded for further processing, in function block 502. In function block 504, the data is buffered for further manipulation. In decision block 506, a determination is made as to whether the data can be properly authenticated. If not, program flow continues through the "N" signal to function block 520 where the data is discarded. In function block 522, the program then signals for a retransmission ofthe data. The system then waits for the next trigger signal, in decision block 500. If properly authenticated in decision block 506, program flow continues through the "Y" signal path where the data is then used to launch the web browser application, as indicated in function block 508. In function block 510, the web browser receives the URL data, which is then automatically routed through the computer modem 208 to the network interface 304 and ultimately to the network 306. In function block 514, the ARS 308 responds by returning the URL of advertiser server 312 to the PC 302. In function block 516, the web browser running on the source PC 302, receives the advertiser URL information from the ARS 308, and transmits the URL for the product file to the advertiser server 312. In block 518, the advertiser server 312 responds by sending the product information to the source PC 302 for processing.

The user may obtain the benefits of this architecture by simply downloading the proprietary software over the network. Other methods for obtaining the software are well- known; for example, by CD, diskette, or pre-loaded hard drives.

Referring now to FIGURE 6, there is illustrated a flowchart ofthe process the ARS 308 may undergo when receiving the message packet 400 from the source PC 302. In decision block 600, the ARS 308 checks for the receipt ofthe message packet 400. If a message packet 400 is not received, program flow moves along the "N" path to continue waiting for the message. If the message packet 400 is received, program flow continues along path "Y" for message processing. Upon receipt ofthe message packet 400, in function block 602, the ARS 308 decodes the message packet 400. The product code is then extracted independently in function block 604 in preparation for matching the product code with the appropriate advertiser server address located in the database 310. In function block 606, the product code is then used with a look-up table to retrieve the advertiser server 312 URL ofthe respective product information contained in the audio signal data. In function block 608, the ARS 308 then assembles message packet 402 for transmission back to the source PC 302. Function block 610 indicates the process of sending the message packet 402 back to the source PC 302 over Path "B."

Referring now to FIGURE 7, there is illustrated a flowchart ofthe interactive processes between the source PC 302 and the advertiser server 312. In function block 700, the source PC 302 receives the message packet 402 back from the ARS 308 and begins to decode the packet 402. In function block 702, the URL ofthe advertiser product information is extracted from the message packet 402 and saved for insertion into the message packet 404 to the advertiser server 312. The message packet 404 is then assembled and sent by the source PC 302 over Path "C" to the advertiser server 312, n function block 704. While the source PC 302 waits, in function block 706, the advertiser server 312 receives the message packet 404 from the source PC 302, in function block 708, and disassembles it. The product information location is then extracted from the message packet 404 in function block 710. The particular product information is retrieved from the advertiser server 312 database for transmission back to the source PC 302. In function block 712, the product information is assembled into message packet 406 and then transmitted back to the source PC 302 over Path "D." Returning to the source PC 302 in function block 714, the advertiser product information contained in the message packet 406 received from the advertiser server 312, is then extracted and processed in function block 716.

Referring now to FIGURE 8, after receipt of a trigger signal, a web browser application on a source PC 302 is automatically launched and computer display 800 presents a browser page 802. Proprietary software running on the source PC 302 processes the audio signal data after being digitized through the sound card 206. The software appropriately prepares the data for insertion directly into the web browser by extracting the product information code and appending keystroke data to this information. First, a URL page 804 is opened in response to a Ctrl-O command added by the proprietary software as the first character string. Opening URL page 804 automatically positions the cursor in a field 806 where additional keystroke data following the Ctrl-O command will be inserted. After URL page 804 is opened, the hypertext protocol preamble http:// is inserted into the field 806. Next, URL information associated with the location ofthe ARS 308 is inserted into field

806. Following the ARS 308 URL data are the characters /? to allow entry of variables immediately following the /? characters. In this embodiment, the variable following is the product information code received in the audio signal. The product code information also provides the cross-reference information for obtaining the advertiser URL from the ARS database 310. Next, a carriage return is added to send the URL/product data and close the window 804. After the message packet 400 is transmitted to the ARS 308 from the source PC 302, transactions from the ARS308, to the source PC 302, to the advertiser server 312, and back to the source PC 302, occur quickly and are transparent to the viewer. At this point, the next information the viewer sees is the product information which was received from the advertiser server 312. Referring now to FIGURE 9, there is illustrated a block diagram of a more simplified embodiment. In this embodiment, a video source 902 is provided which is operable to provide an audio output on an audio cable 901 which provides routing information referred to by reference numeral 904. The routing information 904 is basically information contained within the audio signal. This is an encoded or embedded signal. The important aspect ofthe routing information 904 is that it is automatically output in realtime as a function ofthe broadcast ofthe video program received over the video source 902. Therefore, whenever the program is being broadcast in realtime to the user 908, the routing information 904 will be output whenever the producer ofthe video desires it to be produced. It should be understood that the box 902 representing the video source could be any type of media that will result in the routing information being output. This could be a cassette player, a DVD player, an audio cassette, a CD ROM or any such media. It is only important that this is a program that the producer develops which the user 908 watches in a continuous or a streaming manner. Embedded within that program, at a desired point selected by the producer, the routing information 904 is output.

The audio information is then routed to a PC 906, which is similar to the PC 112 in FIGURE 1. A user 908 is interfaced with the PC to receive information thereof, the PC 906 having associated therewith a display (not shown). The PC 906 is interfaced with a network 910, similar to the network 306 in FIGURE 3. This network 910 has multiple nodes thereon, one of which is the PC 906, and another of which is represented by a network node

912 which represents remote information. The object ofthe present embodiment is to access remote information for display to the user 908 by the act of transmitting from the video program in block 902 the routing information 904. This routing information 904 is utilized to allow the PC 906 which has a network "browser" running thereon to "fetch" the remote information at the node 912 over the network 910 for display to the user 908. This routing information 904 is in the form of an embedded code within the audio signal, as was described hereinabove.

Referring now to FIGURE 10, there is illustrated a more detailed block diagram of the embodiment of FIGURE 9. In this embodiment, the PC 906 is split up into a couple of nodes, a first PC 1002 and a second PC 1004. The PC 1002 resides at the node associated with the user 908, and the PC 1004 resides at another node. The PC 1004 represents the ARS 308 of FIGURE 3. The PC 1004 has a database 1006 associated therewith, which is basically the advertiser database 310. Therefore, there are three nodes on the network 910 necessary to implement the disclosed embodiment, the PC 1002, the PC 1004 and the remote information node 912. The routing information 904 is utilized by the PC 1002 for routing to the PC 1004 to determine the location ofthe remote information node 912 on the network 910. This is returned to the PC 1002 and a connection made directly with the remote information node 912 and the information retrieved therefrom to the user 908. The routing information 904 basically constitutes primary routing information.

Referring now to FIGURE 11, there is illustrated a diagrammatic view of how the network packet is formed for sending the primary routing information to the PC 1004. In general, the primary routing information occupies a single field which primary routing information is then assembled into a data packet with the secondary routing information for transfer to the network 910. This is described hereinabove in detail.

Referring now to FIGURE 12, there is illustrated an alternate embodiment to that of

FIGURE 9. In this embodiment, the video source 902 has associated therewith an optical region 1202, which optical region 1202 has disposed therein an embedded video code. This embedded video code could be relatively complex or as simple as a grid of dark and white regions, each region in the grid able to have a dark color for a logic "1" or a white region for a logic "0." This will allow a digital value to be disposed within the optical region 1202. A sensor 1204 can then be provided for sensing this video code. In the example above, this would merely require an array of optical detectors, one for each region in the grid to determine whether this is a logic "1" or a logic "0" state. One ofthe sensed video is then output to the PC 906 for processing thereof to determine the information contained therein, which information contained therein constitutes the primary routing information 904.

Thereafter, it is processed as described hereinabove with reference to FIGURE 9.

Referring now to FIGURE 13, there is illustrated a block diagram for an embodiment wherein a user's profile can be forwarded to the original subscriber or manufacturer. The PC 906 has associated therewith a profile database 1302, which profile database 1302 is operable to store a profile ofthe user 908. This profile is created when the program, after initial installation, requests profile information to be input in order to activate the program. In addition to the profile, there is also a unique ID that is provided to the user 908 in association with the browser program that runs on the PC 906. This is stored in a storage location represented by a block 1304. This ID 1304 is accessible by a remote location as a "cookie" which is information that is stored in the PC 906 in an accessible location, which accessible location is actually accessible by the remote program running on a remote node.

The ARS 308, which basically constitutes the PC 1004 of FIGURE 10, is operable to have associated therewith a profile database 1308, which profile database 1308 is operable to store profiles for all ofthe users. The profile database 1308 is a combination ofthe stored in profile database 1302 for all ofthe PCs 906 that are attachable to the system. This is to be distinguished from information stored in the database 310, the advertiser's database, which contains intermediate destination tables. When the routing information in the primary routing information 904 is forwarded to the ARS 308 and extracted from the original data packet, the look-up procedure described hereinabove can then be performed to determine where this information is to be routed. The profile database 1302 is then utilized for each transaction, wherein each transaction in the form ofthe routing information received from the primary routing information 904 is compared to the destination tables 310 to determine what manufacturer it is associated with. The associated ID 1304 that is transmitted along with the routing information in primary routing information 904 is then compared with the profile database 1308 to determine if a profile associated therewith is available. This information is stored in a transaction database 1310 such that, at a later time, for each routing code received in the form ofthe information in primary routing information 904, there will associated therewith the IDs 1304 of each ofthe PCs 906. The associated profiles in database 1308, which are stored in association with IDs 1304, can then be assembled and transmitted to a subscriber as referenced by a subscriber node 1312 on the network 910. The ARS 308 can do this in two modes, a realtime mode or a non-realtime mode. In a realtime mode, each time a PC 906 accesses the advertiser database 310, that user's profile information is uploaded to the subscriber node 1312. At the same time, 21 billing information is generated for that subscriber 1312 which is stored in a billing database 1316. Therefore, the ARS 308 has the ability to inform the subscriber 1312 of each transaction, bill for those transactions, and also provide to the subscriber 1312 profile information regarding who is accessing the particular product advertisement having associated therewith the routing information field 904 for a particular routing code as described hereinabove. This information, once assembled, can then be transmitted to the subscriber 1312 and also be reflected in billing information and stored in the billing information database 1316.

Referring now to FIGURE 14, there is illustrated a flowchart depicting the operation for storing the profile for the user. The program is initiated in a block 1402 and then proceeds to a function block 1404, wherein the system will prompt for the profile upon initiation ofthe system. This initiation is a function that is set to activate whenever the user initially loads the software that he or she is provided. The purpose for this is to create, in addition to the setup information, a user profile. Once the user is prompted for this, then the program will flow to a decision block 1406 to determine whether the user provides basic or detailed information. This is selectable by the user. If selecting basic, the program will flow to a function block 1408 wherein the user will enter basic information such as name and serial number and possibly an address. However, to provide some incentive to the user to enter more information, the original prompt in function block 1404 would have offers for such things as coupons, discounts, etc, if the user will enter additional information. If the user selects this option, the program from the decision block 1406 to a function block 1410. In the function block 1410, the user is prompted to enter specific information such as job, income level, general family history, demographic information and more. There can be any amount of information collected in this particular function block.

Once all ofthe information is collected, in either the basic mode or the more specific mode, the program will then flow to a function block 1412 where this information is stored locally. The program then flows to a decision block 1414 to then go on-line to the host or the ARS 308. In general, the user is prompted to determine whether he or she wants to send this information to the host at the present time or to send it later. If he or she selects the "later" option, the program will flow to a function block 1415 to prompt the user at a later time to send the information. In the disclosed embodiment, the user will not be able to utilize the software until the profile information is sent to the host. Therefore, the user may have to activate this at a later time in order to connect with the host.

If the user has selected the option to upload the profile information to the host, the program will flow to the function block 1416 to initiate the connect process and then to a decision block 1418 to determine if the connection has been made. If not, the program will flow along a "N" path to a time to decision block 1420 which will time to an error block 1422 or back to the input ofthe connect decision block 1418. The program, once connected, will then flow along a "Y" path from decision block 1418 to a function block 1428 to send the profile information with the ID ofthe computer or user to the host. The ID is basically, as described hereinabove, a "cookie" in the computer which is accessed by the program when transmitting to the host. The program will then flow to a function block 1430 to activate the program such that it, at later time, can operate without requiring all of the set up information. In general, all ofthe operation of this flowchart is performed with a "wizard" which steps the user through the setup process. Once complete, the program will flow to a Done block 1432.

Referring now to FIGURE 15, there is illustrated a flowchart depicting the operation ofthe host when receiving a transaction. The program is initiated at a start block 1502 and then proceeds to decision block 1504, wherein it is determined whether the system has received a routing request, i.e., the routing information 904 in the form of a tone, etc., embedded in the audio signal as described hereinabove with respect to FIGURE 9. The program will loop back around to the input of decision block 1504 until the routing request has been received. At this time, the program will flow along the "Y" path to a function block 1506 to receive the primary routing information and the user ID. Essentially, this primary routing information is extracted from the audio tone, in addition to the user ID. The program then flows to a function block 1508 to look up the manufacturer URL that corresponds to the received primary routing information and then return the necessary command information to the originating PC 108 in order to allow that PC to connect to the destination associated with the primary routing information. Thereafter, the program will flow to a function block 1510 to update the transaction database 1310 for the current transaction. In general, the routing information 904 will be stored as a single field with the associated IDs. The profile database, as described hereinabove, has associated therewith detailed profiles of each user on the system that has activated their software in association with their LD. Since the ID was sent in association with the routing information, what is stored in the transaction database is the routing code, in association with all ofthe IDs transmitted to the system in association with that particular routing code. Once this transaction database has been updated, as described hereinabove, the transactions can be transferred back to the subscriber at node 312 with the detailed profile information from the profile database 1308.

The profile information can be transmitted back to the subscriber or manufacturer in the node 312 in realtime or non-realtime. A decision block 1512 is provided for this, which determines if the delivery is realtime. If realtime, the program will flow along a "Y" path to a function block 1514 wherein the information will be immediately forwarded to the manufacturer or subscriber. The program will then flow to a function block 1516 wherein the billing for that particular manufacturer or subscriber will be updated in the billing database 1316. The program will then flow into an End block 1518. If it was non-realtime, the program moves along the "N" path to a function block 1520 wherein it is set for a later delivery and it is accrued in the transaction database. In any event, the transaction database will accrue all information associated with a particular routing code.

With a realtime transaction, it is possible for a manufacturer to place an ad in a magazine or to place a product on a shelf at a particular time. The manufacturer can thereafter monitor the times when either the ads are or the products are purchased. Of course, they must be scanned into a computer which will provide some delay. However, the manufacturer can gain a very current view of how a product is moving. For example, if a cola manufacturer were to provide a promotional advertisement on, for example, television, indicating that a new cola was going to be placed on the shelf and that the first 1000 purchasers, for example, scanning their code into the network would receive some benefit, such as a chance to win a trip to some famous resort in Florida or some other incentive, the manufacturer would have a very good idea as to how well the advertisement was received. Further, the advertiser would know where the receptive markets were. If this advertiser, for example, had placed the television advertisement in ten cities and received overwhelming response from one city, but very poor response from another city, he would then have some inclination to believe that either one poor response city was not a good market or that the advertising medium he had chosen was very poor. Since the advertiser can obtain a relatively instant response and also content with that response as to the demographics ofthe responder, very important information can be obtained in a relatively short time.

It should be noted that the disclosed embodiment is not limited to a single source PC 302, but may encompass a large number of source computers connected over a global communication network. Additionally, the embodiment is not limited to a single ARS 308 or a single advertiser server 312, but may include a plurality of ARS and advertiser systems, indicated by the addition of ARS 314 and advertiser server A 316, respectively. It should also be noted that this embodiment is not limited only to global communication networks, but also may be used with LAN, WAN, and peer-to-peer configurations.

It should also be noted that the disclosed embodiment is not limited to a personal computer, but is also applicable to, for example, a Network Computer ("NetPC"), a scaled- down version ofthe PC, or any system which accommodates user interaction and interfaces to information resources.

One typical application ofthe above noted technique is for providing a triggering event during a program, such as a sport event. In a first example, this may be generated by an advertiser. One could imagine that, due to the cost of advertisements in a high profile sports program, there is a desire to utilize this time widely. If, for example, an advertiser contracted for 15 seconds worth of advertising time, they could insert within their program a tone containing the routing information. This routing information can then be output to the user's PC which will cause the user's PC to, via the network, obtain information from a remote location typically controlled by the advertiser. This could be in the form of an advertisement of a length longer than that contracted for. Further, this could be an interactive type of advertisement. An important aspect to the type of interaction between the actual broadcast program with the embedded routing information and the manufacturer's site is the fact that there is provided in the information as to the user's PC and a profile of the user themselves. Therefore, an advertiser can actually gain realtime information as to the number of individuals that are watching their particular advertisement and also information as to the background of those individuals, demographic information, etc. This can be a very valuable asset to an advertiser.

In another example, the producer ofthe program, whether it be an on-air program, a program embedded in a video tape, CD-ROM, DVD, or a cassette, can allow the user to automatically access additional information that is not displayed on the screen. For example, in a sporting event, various statistics can be provided to the user from a remote location, merely by the viewer watching the program. When these statistics are provided, the advertiser can be provided with demographic information and background information regarding the user. This can be important when, for example, the user may record a sports program. If the manufacturer sees that this program routing code is being output from some device at a later time than the actual broadcast itself, this allows the advertisers to actually see that their program is still being used and also what type of individual is using it. Alternatively, the broadcaster could determine the same and actually bill the advertiser an additional sum for a later broadcast. This is all due to the fact that the routing information automatically, through a PC and a network, will provide an indication to the advertiser for other intermediary regarding the time at which the actual information was broadcast.

The different type of medium that can be utilized with the above embodiment are such things as advertisements, which are discussed hereinabove, contests, games, news programs, education, coupon promotional programs, demonstration media (demos), photographs, all of which can be broadcast on a private site or a public site. This all will provide the ability to allow realtime interface with the network and the remote location for obtaining the routed information and also allow for realtime billing and accounting.

Referring now to FIGURE 16, there is illustrated a flowchart depicting an alternate embodiment ofthe disclosure. As described hereinabove, the transmission of encoded information is sensed by a user's computer which, when sensed and decoded, indicates to the computer that the computer is to launch the browser and then forward this information to an intermediate point for effecting a connection between an advertiser or producer and the user's PC.

Referring further to FIGURE 16, there is illustrated a user PC 1600 which has associated therewith browser software 1602 and an application program 1604. The user PC 1600 is operable to run the application program 1604 in the background or the foreground.

This application program 1604, as described hereinabove, is an application program that can detect certain inputs to the user PC 1600, as will be described in more detail hereinbelow. In addition to the application program 1604 running on the user PC 1600 and the browser program 1602 being capable of being run on the user PC 1600, there is also provided an audio player program 1606. This audio player program 1606 is a conventionally available program that allows the user PC 1600 to play audio. This audio is typically received in the form of a compressed audio format-an MP3 format. This compressed format is basically a compressed form ofthe conventional MPEG format. Again, this is a conventional format.

The user PC 1600 is interfaced to a global communication network 1610. As described hereinabove, the global communication network 1610 is a conventional network typically referred to by the name "Internet" involving a plurality of interconnecting nodes and routers. This allows the user PC 1600, through known addressing schemes, to interconnect to a remote location and forward information thereto and receive information therefrom, typically utilizing a TCP/TP protocol. In conventional operation utilizing the network 1610, the user PC 1600 is operable to interface with an audio source node 1612 to receive MP3 audio therefrom over the network 1604. This can be in the form of a popular song or the like such that is transferred thereto. This audio source node 1612 could be associated with an acquaintance ofthe user or even a commercial establishment. However, the primary information transmitted from the audio source 1612 to the user PC 1600 is an MP3 encoded audio program. This MP3 audio program, as will be described hereinbelow, is modified by the originating source ofthe audio to contain therein in an encoded format some routing information which is sensed by the application program 1604 when the audio player program 1606 actually plays the audio. Of course, once the audio is received in the MP3 format, it must first be decoded and then output as an audio signal, this requiring both 27 the decoding step and an analog-to-digital data conversion operation, this being conventional. This is then output on an audio output device 1613.

The audio source 1612 must receive the audio program from some originating source. This may typically be from some other location which generated the audio source and which has transmitted it to an end user. The end user may receive the source, copy the source and transmit it to multiple individuals. This MP3 audio program could be transmitted to many individuals in a chain. As will be described hereinbelow, it is the user PC 1600 having the application program 1604 running in the background that will provide an interconnection to a producer node 1614. It is noted that the application program 1604 will typically be integrated with the audio player program 1606, although this need not be the case.

In operation, after an audio program with an MP3 format encoded with the routing information therein is received by the user PC 1600 and stored locally thereat on a hard disk 1618 and then played utilizing the audio player program 1606, or alternatively, received and immediately played with the audio player program 1606, the application program 1604 will sense routing information in the program, which was embedded therein by the originator of the program. This is typically not readily apparent to the user when listening to the audio program, although it is, in the preferred disclosure, audible. When the audio program is played, the application program 1604 senses the information in the embedded product information, utilizes this information to launch the web browser and the browser program

1602 and contact an ARS location 1620 over the network 1610. It is noted that the embedded information may be any information that can be recognized by the application program, and need not be actual information about the product. It could be some type of information correlating to an advertiser. As will be described hereinbelow, the embedded information has no relationship with anything except as defined in an MP3 header database at the ARS location 1620, as will be described hereinbelow.

The information transmitted to the ARS location 1602 by the application program 1604 comprises the embedded information from the audio program, user information stored at the user PC 1600 and the user's location on the network 1610. The ARS location 1620 28 utilizes this information to extract pre-stored and associated information from the MP3 header database 1624. As will be described hereinbelow, this information is pre-stored by the producer which allows the ARS 1620 to determine where the user PC 1600 should be directed over the network 1610. This pre-stored information, derived from a matching operation, is then transmitted back to the user PC 1600 and the browser software 1602 instructing the browser software 1602 to connect to a predefined location on the network 1610. This predefined location is the producer location 1614. In addition to instructing the browser 1602 what location to connect to, information forwarded back to the user PC 1600 by the ARS 1620 can also provide some user information or other information for delivery to the producer node 1614. The producer node 1614 will then make contact with the user

PC 1600 and the browser software 1602 in order to provide a display to the user, i.e., it will effect a network connection thereto via a TCP/TP link. For example, while the user is listening to the audio program, advertising can be provided to the listener at the associated user PC 1600. This will allow the producer 1614 not only to derive information about who is listening to their software, legally or illegally, but also will allow the producer to possibly provide some information to the user, solicit additional sales from the user, etc.

Merely by playing the audio program, the audio player program 1608 will now interface with the application program 1604 to launch the browser 1602 in order to contact the producer. By storing information at the ARS location 1620, the producer need not store a great deal ofthe actual reading information in the MP3 audio track. The large portion of the routing information required by the user PC 1600 in order to connect to the producer 1614 is contained within the application program 1604. This allows a single program to access a single location, the ARS location 1620, in order to facilitate a connection with a producer 1614. If, for example, the producer 1614 were to change locations on the network 1610, i.e., change the universal resource locator (URL), this need only be updated in a single

MP3 database, the MP3 header database 1624 at the ARS location 1620. Further, the small amount of information required to be stored in the MP3 audio header on the audio program is minimized due to the interaction with the application program 1604 and the fact that the actual routing information is stored at the ARS location 1620. Referring now to FIGURE 17, there is illustrated a diagrammatic view ofthe information required to be forwarded to the ARS location 1620 and then to the producer location 1614. The original MP3 audio program is comprised of an actual compressed MP3 audio track 1700 which has associated therewith some type of audible routing or product information as a product header 1710. This is a tone which can be decoded due to the fact that it is comprised of multiple tones that are outputted in a predetermined sequence. (However, this need not be a tone. It could be any type of encoded information, in either the digital or audio domain.) This sequence, when decoded, indicates certain binary numbers. This tone can be embedded at any location within the MP3 audio track 1700, although it is illustrated in FIGURE 17 as being at the beginning, i.e., a header. Depending upon the producer's desire, this program can be placed at any desirable location which would not aesthetically detract from the program.

When this audio program is played, the routing or product information in the product header 1710 is then sensed by the application program 1604. In addition to being sensed by the application program 1604, this tone or audio header contains information that uniquely identifies the audio program, albeit only at the ARS location 1620. Therefore, this information is assembled into a packet for being transmitted to the ARS location 1620. The application program 1604 has predisposed information contained therein as to the location ofthe ARS 1620 on the network 1610. Therefore, it need only assemble this information and route it to the ARS 1620. However, in addition to this information contained in header

1710, additional information such as information about the user at the user PC 1600 may be transmitted in the form of a user ID. This user ID is associated with information at the ARS location 1620 that is typically input to the ARS location 1620 from the user PC 1600 when the user PC 1600 is loaded with the audio player program 1606 or the application program 1604, the preferable situation being when the audio player program 1606 is integrated with the application program 1604. This user information at the ARS location 1620 can contain an entire user profile ofthe user. However, when created, this user profile is immediately transmitted to the ARS location 1620 and stored in a database associated therewith. All that is transmitted from the user PC 1600 thereafter is the user ID which is assigned to that user when installing either the application program 1604 or the combination ofthe application program and the audio player program 1606. 30

When assembling the packet for transmission to the ARS location 1620, the routing or product information in the product header 1710 is stored in the field 1712 as unique program information. A field 1714 is associated with the user ID and then an ARS routing field 1716 is provided in the packet. There is provided with this packet certain TCP/TP overhead in a field 1718. This is transmitted to the browser 1602, after launching thereof, as a URL string. This URL string typically is comprised ofthe domain name ofthe ARS location 1620 uniquely defining the ARS location on the network 1610, followed by informational characters. These information characters will comprise the information in the field 1712 and the field 1714. The field 1716 constitutes the ARS location 1620 routing code. Routing this information to the ARS 1620 is a conventional process.

Once the ARS location 1620 receives the routed packet comprised ofthe field 1712- 1718, then this ARS locationl620 will create a packet for routing back to the user PC 1600. This packet will contain re-routing information in a field 1720 which instructs the browser 1602 where the location ofthe producer 1614 is on the net 1610, i.e., this is a hands-off operation. In addition to the re-routing information in field 1720, there is provided a field

1722 associated with the user information which was extracted from the MP3 header database 1624 and the product information in a field 1724 which was also extracted from the MP3 header database 1624. Also contained within the packet is a field 1726 instructing the network 1610 how to route this information back to the user PC 1600, in addition to a TCP/TP overhead field 1728. This is directed to the user PC 1600 which will then, through the conventional use ofthe browser 1602 and the HTML language, create an additional packet consisting of a producer routing field 1730, a user information field 1732 corresponding to the user information field 1722, a product information field 1734, corresponding to the product information field 1724 and a TCP/TP overhead field 1736. This will be utilized by the browser 1602 in order to determine how to route the information in fields 1732 and 1734 over to the producer 1614 for use thereby. At this point, a network connection has been made to the producer location 1614 and information relayed to the producer at node 1614 with information as contained in the MP3 header database 1624, all of this transparent to the actual user. Referring now to FIGURE 18, there is illustrated a flowchart for the overall system operation. The program is initiated at a System block 1800 and then proceeds to a function block 1802 wherein the MP3 audio is transmitted to the user PC 1600. The user PC 1600 is then operable to store the information in the hard disk 1618, or other similar storage media, and then play will then be stored MP3 audio followed with the audio player program 1601.

This is played for audio output on an audio output device 1613. The application program 1604 may be a separate program as described hereinabove or be integrated with the audio player program 1606. This receive and play operation is indicated by a function block 1804. It should be understood that the actual receipt ofthe information may trigger the audio player program 1606 to actually decompress and play the audio file. Although the application program 1604 may be embedded in the audio player 1606, the application program 1604 is operable to always be active in the background, such that the playing ofthe audio file will trigger the application program 1604 to launch the browser 1602. This is facilitated through a detect function, as indicated by a function block 1806, wherein playing ofthe audio file, i.e., decompression and output thereof through the audio output device

1630, results in output ofthe embedded product information associated with the audio program. Detection can be either in the audible domain or the digital domain, prior to conversion to the audio audible output signal 1630 from the digital domain. In any event, it is the detection ofthe signal that triggers the overall operation described hereinbelow.

When the MP3 signal is received by the user PC 1600, it is typically received along a path labeled MP3 in FIGURE 16. This path is connected to the audio source 1612. After detection, this product information contained in the "tone" or other product header 1710, is then forwarded to the ARS location 1620, as indicated by function block 1808. This is funneled along a path labeled "Routing Info" to the ARS location 1620. A matching operation is then performed in the ARS location 1620 utilizing the MP3 header database 1624, as indicated by a function block 1810. This operation then performs a "hand off operation to the user. This is indicated by a Redirect path from ARS locationl620 back to the user PC 1600, as indicated in FIGURE 16. This, as described hereinabove, provides information as to the user profile, product information, all of which were stored in the MP3 header database 1624. This information is extracted due to the fact that the ARS locationl620 has received from the user PC 1600 both the user ID information and minimal product information through the code embedded within the product headerl710 in the audio track.

The program then flows to a function block 1812 wherein this information redirected from the ARS location 1620 back to the user PC 1600 is utilized to provide a connection with the producer location 1614 through a path 1632 within the network 1610. This is illustrated as a bidirectional path, since a TCP/TP protocol is utilized requiring packets to be transferred from the user PC 1610 to the producer's network location 1614 and then returned. As described hereinabove, this is typically in the form of a "web page" which provides information about the producer or manufacturer. Since the user not only has information as to the query, i.e., a request for web page information, but also includes user information, this allows the producer location 1614 to "customize" the information transferred back to the user in the form of both information corresponding to the actual product that triggered the connection and to some information about the user. For example, if the song was a popular song by singer John Doe, requested by user Jane Doe, then the producer could provide information regarding this song and similar types of songs associated with the type of music performed by John Doe to a user ofthe female gender. However, there could be demographics contained within the user profile and this could be utilized to further refine the information sent back to the user PC 1600. This return of information from the web page ofthe producer location 1614 is indicated by a function block 1814. Once this connection has been made, the program flows to an End block 1816.

Referring now to FIGURE 19, there is illustrated a flowchart depicting the operation at the user PC 1600. The program is initiated at a Start block 1900 and then proceeds to a function block 1902. At the function block 1902, the function of monitoring the audio player program 1606 for a tone is indicated. Since the audio player program 1606 is required in order to extract the information from the MP3 audio program file stored in either the hard disk 1618 or received directly from the audio source 1612, launching ofthe audio player program 1606 will also launch the application program 1604. The program will then flow to decision block 1904 to determine if the tone has been detected within the audio program file. It should be understood that each audio program file played by the audio player 1606 may not contain the tone or the embedded product information. If not, the program will flow along the "N" path back to the input of function block 1902. However, if the tone or embedded product information is detected, the program will flow along the "Y" path to a function block 1906 wherein the browser will be launched. The program will then flow to a function block 1908 to assemble a packet indicated in FIGURE 17 for transfer to the ARS location 1620 and then to a function block 1910 to transmit the packet back to the location ARS 1620. This transmission is facilitated by the fact that the application program 1604 is aware ofthe address or URL ofthe ARS 1620 on the network 1610. The program then flows to an End block 1912. Once this operation has been initiated, the information transferred to the ARS location 1620 and that information processed at the ARS location 1620, then the application program 1604 is not required for further processing. This merely then requires interface between the ARS 1620 and the browser program 1602 using, typically, an HTML program language.

Referring now to FIGURE 20, there is illustrated a program depicting the operation ofthe audio player program 1606. This is initiated at a block 2000 and then proceeds to a function block 2002 to receive the MP3 file, either directly from the network 1610 in the audio source 1612 or from the hard disk 1618. The program then flows to a function block 2004 to decode this MP3 file, i.e., decompress and play the program in an audio format, and then to a function block 2006 to output the audio on the audio output device 1630. The program then proceeds to an End block 2008. As described hereinabove, this audio output operation requires a data conversion operation, with the application program 1604 operable to detect the tone or embedded product information in either the digital version ofthe file after decompression thereof or in the audio version on the other side ofthe analog-to-digital conversion operation.

In summary, there has been provided a system to allow an audio file that is transmitted over a global communication network to have embedded therein product code information that is associated with a routing operation to a predefined location. When this audio file is received at a user's PC and decoded and output, a detection program detects the presence of embedded information. This embedded information is then utilized by a resident application program in the user's PC to launch a browser and transfer this embedded information to a remote intermediate location. This remote intermediate location has associated therewith a database, which database is operable to match the database information with the product and also with routing information for that embedded information. This routing information is predisposed in the database and may be associated with some advertiser that would like to reach users ofthe audio file or with the producer of the actual audio file. Once the remote intermediate location has determined this information, it returns the information back to the user's PC and the browser running thereon such that the browser can then contact the routed-to location indicated in the database directly. Additionally, there can be certain information provided by the remote intermediate location in addition to the routing information to the end location for use thereby. Alternatively, the intermediate remote location could directly contact the desired routed-to location to allow that location to directly contact the user PC without having to go back to the browser ofthe user PC, although this is a more complex routing operation.

Although the preferred embodiment has been described in detail, it should be understood that various changes, substitutions and alterations can be made therein without departing from the spirit and scope ofthe invention as defined by the appended claims.
