Description

WO 99/51030 PCT/US99/071~46 APPARATUS AND METHOD FOR WEB-CASTING
OVER DIGITAL BROADCAST TV NETWORK
Field of the Invention This invention relates generally to World Wide Web ("WWW") based broadcast data system. More particularly, this invention relates to systems and services for providing one-way Internet data delivery over digital broadcast TV network.
Background of the Invention In the next few years, digital television will become the overriding standard for broadcasting television and cable signals in the United States. This will require that all consumer households purchase new digital televisions or digital to analog converter systems which will allow the old fashioned analog televisions to convert the incoming digital signals to analog signals for viewing. Since cable signals are the ubiquitous providers of most television content today, consumer's will also have to purchase or otherwise be provided with digital set top boxes which will be placed in the consumers home and hooked up to the digital television. The digital set top box will be adapted to receive the incoming digital signals from the local or regional cable headend and convert or descramble them into signals carrying the desired content for broadcast by the digital television. The digital. set top boxes will be built according to particular standards promulgated by the government and standards committees, and will have varying degrees of computing power.
The Internet or WWW has also become a ubiquitous part of our lives in the last part of the twentieth century. One of the downsides of the internee= today is that in order to have access to it, one must own a fairly expensive personal computer. Even though personal computers have reduced greatly in price today, many individuals have no desire to purchase one and learn its intricacies in order to have access to the WWW. Additionally, providing real time access to complicated video content is not possible with current personal computers since the transport media and modems which mmst bring Internet signals to personal computers are not fast enough and do not have enough bandwidth to make this possible.
Some prior art systems have attempted to transport Internet signals to current analog television systems by placing a limited, customized server at the consumer's premises and hooking up the server to the consumer's analog television. This server is much less expensive a than personal computer, and concomitantly much less powerful. The same problems of speed and bandwidth still exist, arid these servers will not interface with digital televisions without the use of the digital set top box described above and which is on the near horizon.
However with the advent of digital television and the build out of the hybrid fiber-coax infrastructure rapidly occurring in many communities throughout the United States today, it will soon be possible to provide enough bandwidth to meaningfully provide high content video signals to a device which will be able to handle digital signals with massive content therein. What remains to make transport: of the signals practical is the speed of delivery, which if digital, could be accomplished by cable modems and the like.
There is therefore a long felt need in the art for systems, methods and software which can integrate Internet services with the coming digital television regime which will take the content-rich digital signals from cable networks. It will be greatly desired to provide access to the WWW through the Internet and broadcast the Internet on digital televisions of the future.
Additionally, there wi:Ll be a strong need for seamless integration of Internet services and digital television signals so that the consumer of both can easily access the Internet and watch the desired content without interruption. These needs have not heretofore been fulfilled in the art.
Summary of the Invention The aforementioned long felt needs are met and problems solved by one way broadcast systems provided in accordance with the present invention. The systems preferably comprise a headend cable system adapted tc> receive MPEG data, analog signals and signals from the Internet. Even more preferably the systems comprise means for converting the analog signals to MPEG signals and means for combining 1_he MPEG data and converted MPEG signals.
Still more preferably, the systems comprise means for transporting the combined signals to a digital signal.
Broadcast systems provided in accordance with the invention also accommodate the above described long felt needs. The broadcast systems preferably comprise means for combining Internet data streams and video data streams, means for transporting the combined data streams to a digital television, and means for integrating and converting the transported data streams for use by the digital television.
Still more preferably, methods of one way broadcasting accommodate these long felt needs. They preferably comprise the steps of combining Internet data streams and video data streams, transporting the combined data streams to a digital television, and integrating and converting the transported data streams for use by the digital television.
The systems and methods provided in accordance with the present invention thus provide seamless integratibn of Internet services and the coming digital television signals. The systems provide functionality in the headends of cable systems to multiplex MPEG video signals and Internet signals into MPEG
channels which can be customized fox each consumer's particular use and demands. Onf'_ way interactivity is provided and customized software at the local digital set top boxes allows the system to be versatile .and economical. Such results have not heretofore been achieved in the art.
The MoreCast service is a one-way Webcasting service that is carried using digital TV transport streams. MoreCasts'"
provides Webcasting service to the digital set-top box in a one way digital broadcast TV network such as Hybrid Fiber Coax (HFC) or DBS (Direct Broadcast Satellite) network or any other broadcast network. The service can generate additional revenue streams for network operators or content providers in majority of the one way digital video service coverage areas. By utilizing the high speed broadba.nd network bandwidth, MoreCasts"' can provide broadcast news, sports, local weather, and stock quote information from the World Wide Web to TV viewers at home. The MoreCom system also allows the broadcast web content in context to the digital video program being broadcasted. Consumers can also receive program synchronous Webcasting information for each segment of the digital video programming. For example, one can access additional Web based information such as a tnleb page about a TV commercial currently showing on TV. Furthermore, a consumer can access the Webcasting information interactively just like surfing through the Web. In addition, a consumer can access customized Webcasting cc>ntent to his or her preference such as personal stock quote or favorite sport teams news. In one-way networks, MoreCastSM enables users to have the real time interactive experience at very low cost.
There are three types of MoreCast services:
MoreCast Broadcast Data: These are the HTML data broadcast universally throughout all the digital channels to all the clients associated with a headend. Examples include: Electronic Program Guide (EPG), MoreCom Home navigation page, general community information, breaking news, local weather information, local school information, etc. It is usually required that these information are on the broadcast data carousal for all the physical channels so that. the user can always access these HTML
data and watch any TV channel at the same time. MoreCast Simulcast Data: HTML ba~;ed Webcasting contents are associated with each digital broadcast TV channels. For each MPEG-2 program with a multiple program transport stream, there is a data carousal that carries HTMh data coming from specific Web site for different type of services. The carousal is synchronous with the digital broadcast program contents. Examples include: programming provider's key Web page:, advertisement related to the program, news related to the program, etc. The simulcast data is available all the clients who are: tuning to the TV program segment with which the data is associated. MoreCast Personalized Data: HTML
based Webcasting contents are customized based on each user's individual profile and viewing time. Statistically, many users may want to access a. different subset of the real time information during specific viewing period. This information is also associated with Esach MPEG TV program but may not be synchronized with TV content. It should be available all the time from the data carousal upon each user's demand.
The MoreCom system contains server products and client products. In a one way HFC network, or satellite based delivery system, one way Webcasting service can be enabled through MoreCom server at local headend or satellite distribution center. The Web based content can be multicasted in conjunction with digital video over the satellite or through local headend to provide personalized Internet based contents on MoreCom client's TV
set.(MoreCast).
Those with skill in the art will better understand the invention by reading the following detailed description of the invention in conjunction with the drawings which are first described briefly below.

Detailed Description of Preferred Embodiments Referring now to the drawings wherein like reference numerals refer to like elements, Figure 1 is a diagram of the architecture of a one way digital cable network 10 of the present invention. The network 10 comprises a headend 20 which preferably interfaces to a hybrid fiber-coax ("HFC") transport network. While HFC is dlesired it will be recognized by those with skill in the art that other transport media may be utilized such as, without limitation, standard coax or wireless. All such embodiments are intended to be within the scope of the present _ g _ invention.
Analog receivers 30 and digital receivers 40 interface with an MPEG-2 encoder 50 and an integrated electronic receiver 60 respectively to receives video signals for broadcast to the consumers. In the case of the analog signals, the MPEG-2 encoder 50 converts the analog signals to digital MPEG-2 format. If the signals are received in digital MPEG-2 format, the integrated receiver 60 conventionally receives them. The MPEG-2 signals are remultiplexed at 70 and bussed to a broadcast server 80 provided in accordance with the present invention.
Preferably, the broadcast server 80 is also interfaced to a LAN 90 which has dial up access through a server 100 to the Internet and WWW 110. The broadcast server 80 transports the composite digital television and Internet signals to a modulator 120 which modulates the signals and upconverts them to the appropriate frequencies. A converter 130 outputs the modulated signals to an HFC network: 140 which transports the signals to the digital set top boxes 150 at the consumer premises. The MPEG-2 transport streams are more preferably arranged into multiple data channels in each transport stream inside one 6 MHZ channel. The digital set top boxes wi:Ll preferably have contained thereon the appropriate software provided in accordance with the present invention to integrate the Internet and digital television signals, and to provide interactivity for the consumer.

In accordance with the invention, the system of Figure 1 will broadcast data in hypertext markup language~(HTML) to all consumers associated with the headend 20. These included for example, Electronic Programming Guides, Navigation Pages, general community information, breaking news, weather, etc. These data will always be on the broadcast carousal for all the 6 MHZ
channels so that the consumer can always have access to these HTML pages and watch television at the same time. To simulcast data, HTML content is associated with each digital or broadcast TV channel. For each MPEG-2 program with multiple program transport stream, there is a data carousal that carries HTML data coming from the specific Web Site for different types of services. The carousal is synchronous with the digital broadcast program content. These include for example, provider's key Web Z5 pages, advertisement related to program being watched, news related to the program being watched, etc. To send personalized data, HTML based Webcasting content may be customized based on each consumer's individual profile and viewing time.
Statistically, many consumers may desire access to a different subset of the real timE: information during specific viewing periods. This information is also associated with each MPEG TV
program but may not be synchronized with the TV cantent. It will be available all the time from the data carousal upon each consumer's demand.

The MoreCast (which is a trademark of the owner of the present inventions and is used to denote the invention throughout) end to end aystem provides broadband Internet data broadcasting through an existing digital TV network and a set-top box. A typical system architecture in a one way HFC network that also provides digital TV broadcast is shown in Figure 1.
In a digital TV network configuration, the HFC headend receives analog TV broadcast channel from the satellite system and real time MPEG-2 encoder encodes the signal into MPEG-2 single program transport. stream typically at 3 Mbps to 8 Mbps.
The compressed digital format will provide much more efficient transmission of programs into local HFC network. If the headend has a digital satellite downlink Integrated Receiver Transcoder ( IRT) , it should be able to receive the satellite signal that carries digital MPEG-2 compressed stream. It performs demodulation, FEC (Forward Error Correction), and decryption. It then outputs the retrieved MPEG-2 multiple program transport stream to the MPEG-2 transport remultiplexer. The MPEG-2 remultiplexer can receive single program transport streams or multiple program transport streams through DVB (Digital Video Broadcasting) ASI (Asynch:ronous Serial Interface) up to 270 Mbps.
Since each 6 MHZ cable channel can only fit about 27 Mbps using 64 QAM modulation, a remu:Ltiplexer is required to remultiplex the programs in order to fit into these channels. The remultiplexer can perform remultiplex:ing single or multiple program transport streams into multiple program transport streams a~ different bit rates, re-assign PID (packet ID), adjust PCR (Program Clock Reference), and modify P.AT/PMT (Program Association Table/Program Map Table), and insert conditional access messages such as ECM
and EMM.
At the physical layer, typically a 64 QAM modulator is used for each 6 MHZ cable channel to provide 27 Mbps of digital capacity downstream. In addition, the modulator will also provide Forward Error Correction (FEC). The in-band downstream channels typically occupy from 50 MHZ to 750 MHZ in an HFC spectrum shared between analog and digital programs.
The MoreGateT"' (.also a trademark of the owner of the present invention) server 80 for one way Webcasting service (MoreCastSM) is located. in the head-end to serve as the Webcasting gateway from local or World Wide Web Internet to digital video network. Webcasting contents can be generated through Internet from a ~°emote location. They can be downloaded to the MoreGateT"' server and "pushed" to the digital set-top box through the digital network. Program synchronous Web contents associated with digital- TV channel is mapped onto MPEG-2 transport streams on multiple data carousals. The system also allows interactive navigation through the Webcasting contents by the digital set-top box.

The MoreGate'~'' server preferably interfaces with an Internet proxy server through Ethernet to retrieve Web contents.
It has output of DVB A:3I format that carries MPEG-2 transport stream. The output feed~c the MPEG-2 remultiplexer. It is managed by MoreCom Resource Manager 155 (MoreManageT"') through Ethernet using SNMP for bandwidth and PID management.
MoreManage is developed to manage Webcasting services provided by MoreCom (the: owner of the present invention). Three major functions of MoreManage includes: (1) Manage MPEG-2 resource assignment (PID, bandwidth etc.) for services provided from MoreGate servers; (2) Collect and maintain client profile and usage and interface with billing and OSS (Operation Support System) and subscriber management system; and (3) Connection management interface with the System Controller that manages MPEG
encoder, IRT, Remux, and Modulator.
Referring to Figure 2, a system diagram of the server environment to provide the above referenced functionality is shown. On the server side 160, a hypertext transport protocol(HTTP) proxy server 170 is provided which contains the particular applications 7.80 desired to transport. An application program interface (API) 190 is provided which interfaces to the HTML/MPEG gateway and library 200 which is implemented by server 80. The content is output by a high speed MPEG input/output interface 210.

On the client side 220, the application is input to a HTTP engine 230 where a cantrol block 240 allows the consumer to navigate 250 according to particular protocols 260 for example UDP and/or IP 270. An MPEG-2 transport driver 280 and decoder 290 handle the incoming digital signals.
In the Gateway server 80, the MoreCast application module 180 is the main module that controls when the Web data will be broadcasted into the digital video network. It can perform HTML
data fetching through HTT:P proxy module, translate the data into the format that digital set-top boxes can process, schedule the data event broadcasting, request network resource required, and manage data and control interfaces. The HTTP proxy server is responsible to fetch the Web data from the Internet based on the requests from the MoreCast: application module. HTML data will be mapped onto the MPEG-2 transport stream in the HTML/MPEG data protocol module. A control map is preferably generated in the control protocol module 295 for navigation, channel link for one way broadcast services. Both data and control will be sent through MPEG high speed IfO such as DVB ASI to the digital video network.
In the Client side: 220, the MoreCast application module 180 has a user interface. It sends requests to a MoreCast client engine that in turn interfaces with both MoreCast data protocol and MoreCast control protocol. MoreCast data protocol will extract Web data through MPEG transport private data section based on the navigation .and channel information from the control map extracted by MoreCast control protocol. The data and control information are extracted from MPEG-2 transport driver that controls the MPEG-2 transport hardware in the digital set-top box.
In order to navigate between and among the various options discussed above, a browser and navigation menu will preferably be provided. Referring to Figure 3, the layers of navigation are preferably illustrated. A consumer can select a digital video channel and a user interface can be enabled on the television screen. A browser 300 will be enabled and a main menu 310 will show broadcast 320, Web 3'30, Video 340 and Mail 350 which are some preferable options. Choosing broadcast 320 for example enables a broadcast submenu 360. This enables broadcast 370, simulcast 380 or personalized 390 options, for example.
Choosing broadcast 370 enables a navigation page 400 for a common HTML stream 1, 2, 3 at 4.10. Selecting simulcast 380 enables a navigation page 420 which will go to a series of data channels associated with one 6 MHZ channel which thus has multiple HTML
events 1,2 at 430 for viewing. By selecting personalized 390, the user will choose only that channel which matches the MAC or IP address associated with his or her set-top box.

After the user ;elects the particular service desired from the menu, the associated root channel navigation page from the data channel is provided. For example if the Cable News Network (CNN) decides to support simulcast services, it will need to generate a CNN specific channel navigation page that has a URL
440 to all the start pages associated with each cluster pages that constitute the simulcast service. The user can go to the Web contents associated with the selected stream, and within each stream the user can go to each URL linked to the pages as required.
Given the above services offered through MoreCast, a user can access any information from one of the above services at each given time. There can be many different navigation models. The design goal of the navigation model is to be user friendly and standard Web content based.
~ Menu: this is the:navigation menu which is different from the browser itself. The menu system can identify the type of MoreCast service that user want to access: broadcast, simulcast, and personalized, since one can not access more than one service at each time. This can be completely HTML based and is common for all the users and channels. This can be changed from downloading once every month or so ~ Contents: all the MoreCast content for three services can be viewed througl:~ many data channels, Each data channel has a root page that indicates the list of data streams.
Each data stream contains a group of hyperlinked Web pages. In the ca:3e of simulcast, the stream becomes the event that has start time and duration. All the contents are standard HTML based. All the content can be generated by content provide=_r through standard Web authoring tools .
The 1-ayers of navigation can be explained in the following picture:
1. User can select o:ne digital video channel, e.g. CNN. The MoreCast service user interface can be enabled on the screen. It will show the MoreCom Browser button such as "MoreCast" "MoreWeb" and "MoreVideo" and "MoreMail" etc.
2. User can select t:he MoreCast service button on the TV.
This will bring a local menu for MoreCast services. It will show the MoresCast service buttons such as "MoreCast Broadcast" "MoreCast Simulcast" "MoreCast Personalized".
Selecting "MoreCae>t Simulcast" while watching CNN will go to the data channel associated with CNN. Only one data channel is associated with one video program. There are many simulcast data channels in one physical channel. And there can be only one broadcast channel shared for each 6 MHZ, which are not associated with the video program.

There can be many personalized channel in one physical channel.
3. After the user selects the MoreCast service type on the local Menu, it will get the associated root channel navigation page :From the data channel. For example, if CNN decides to support MoreCast Simulcast service, it will need to generate a CNN specific channel navigation page that has URL to all the start page associated with each clusters of pages (data stream or event) that constitutes a service such as CNNfn, CNNevent (associated with each commercial) etc.
4. Now, the user can go to the Web contents associated with the selected stre<~m. User can go back to the start of the stream or the claannel navigation page easily at any point.
5. Within each stream, user can go to each URL linked to the pages as it required.
Referring to Figure 4, both the data and control information can be carried over MPEG-2 transport streams in the format defined in this Figure. Basically, the HTML pages (URLs) and their control map information are either mapped directly onto the sections of the MPEG-2 transport stream or mapped through intermediate layer such as UDP/IP and then encapsulated in the sections of the MPEG-2 transport stream. Multiple sections form a table. Each table can be separated and filtered by the set-top decoder through tableID~ and/or tableID extension fields. The MPEG-2 table structure segmented and carried over MPEG-2 transport packets. MPEG-2. packets can be filtered through the PID
(packetID) by the decoder.
The hierarchy of HTML navigation of the MPEG network in accordance with the pre~~ent invention is illustrated in Figure 5. HTML program association tables 450 are generated. These tables identify the list of the data channels (programs) in the transport stream within l.he selected 6 MHZ. They also identify the type of data channel and video program linkage, if any, and give the location of the program map table. The program map table identifies the list of data streams inside each data channel and their type and properties such as URL to MPEG
resource map, and gives the location of the channel navigation page. The descriptors dive detail for each stream inside the program tables. Concurrently, HTML program map tables 460, HTML
event information tables 470, HTML session information tables 480 are all generated. For example, the program tables 460 support several HTML streams 49!) and associated URLs 500. The event information tables 470 support particular events 510 and associated URLs 520. Similarly, the session information tables 480 support HTML streams 530 with associated URLs 540. This Figure describes the control map hierarchy required for navigation and channel linkage in the one way data broadcast environments.
The control map: are generated by the server in the headend and transmitted periodically to the client through the digital broadcast network. The control maps are preferably partitioned into the fallowing hierarchy:
~ HPAT: HTML Program Association Table. This table identifies the last of the data channels (programs) in this transport stream within the selected 6 MHZ. It also identifies the type of data channel and the video program linkage if there is any. It also gives the location of the other control maps listed below.
HPMT: HTML Program Map Table. This table identifies the list of data streams inside each broadcast data channels and their type and properties such as URL to MPEG
resource map. It also gives the location of the channel navigation page.
HEIT: HTML Event 7:nformation Table. This table identifies the list of data events inside the simulcast data channel that is associatE~d with each video programs and their type and properties such as URL to MPEG resource map.
HSIT: HTML Session Information Table. This table identifies the list of data streams inside the personalized datai channels and their type and properties such as URL to Ml?EG resource map.
Referring to Figure 6, when a single 6 MHZ channel is tuned at 550 fox example,, the television is tuned to the program 560 and the server main menu is enabled 570. The user selects with a local remote device the particular service desired 580 such as, for example, broadcast with associated program association table 450. The channel for the selection is then preferably enabled at 590 with its associated program map table 470. The navigation page is then preferable displayed at 600.
In either case, navigation of the pages are accomplished at 610 and the URL's for the channel are then viewed.
Upon selection of a particular video channel by the user, a 6MHz spectrum is selected and a digital video program inside this spectrum is also selected. The set-top will parse the HPAT
in the selected MPEG transport stream. This will give the location of the HPMT and HEIT and HSIT in the transport streams.
In selecting the broadcast mode, the location of the HPMT is identified and the retrieved from the transport stream. The set-top can use control information provided by HPMT to navigate through the broadcast data in the data carousal.
In selecting the :simulcast mode, the location of the HEIT
that is associated with t:he current video program is identified and retrieved from the transport stream. The set-top can use control information provided by HEIT to synchronize and navigate through the simulcast data in the data carousal.
In selecting the personalized mode, the location of the HSIT is identified and retrieved from the transport stream. The set-top can use control information provided by HSIT to identify, update, and navigate through the personalized data in the data carousal.
The computer and software architecture which implements the present invention is structured in a modular way using object IO oriented design. This allows the modules to be changed and refined along with system design improvement. The system also satisfies real time proxy performance. The system is transportable to virtual:Ly any platform, and can be implemented on a PC windows NT platform for example, or in UNIX. The system is preferably programmed in C and Visual C++ 5.0 and uses the SQL
5.0 Database Server. The: graphical user interface is either the Web Browser or programmed in Visual C++. Either the APACHE' proxy server or MICROSOFT praxy server is utilized.
The systems and methods provided in accordance with the present invention thus provide seamless integration of Internet services and the coming digital television signals.
