Definitions
- This invention relates to a system for conveniently disseminating data in a wide area communications network, in particular for distributing digital data to computer systems at terminals of a global packet-switched computer network such as the Internet.
- a major problem suffered by users of wide area networks is the limitation imposed by the maximum reliable data transfer rate for conveniently accessible communications channels. This problem can be acute for those using voice channels available in the public switched telephone network to transmit data, especially when attempting to access files containing high resolution graphics, audio or video data characteristic of multimedia works.
- the transfer rates utilised on voice channels for digital data typically range from 14,400 bps up to approximately 56,000 bps when employing advanced modulation schemes. Whilst a nominal data transfer rate of 33,600 bps is adequate for dealing with text or low resolution graphics files, a voice channel operating at this rate continuously can take around 5 minutes to transfer 1 MB of digital data. Data files containing multimedia works can typically range from a few megabytes to hundreds of megabytes in size. Accordingly, time and associated cost constraints become an overriding factor for users wishing to access large data files over voice communications channels.
- local computer system includes an individual computer terminal or a local area network of such terminals
- remote site includes computer systems operated by information providers and interconnected via a wide area network for interaction with a plurality of local computer systems
- storage media means any and all media devices capable of storing electronic data, including compact disc (CD), CD-R, CD-RW, digital versatile disc (DVD),
- DVD-RAM, DVD-R, DVD-V and large capacity removable magnetic tape, disc and solid state memory cartridges which may accessed by drives attached to or incorporated into a local computer system.
- the invention resides in a method for disseminating data to users of local computer systems connectable to a wide area network, the method including the steps of: producing portable storage media containing first portions of the data, which first portions are substantially static in nature, for distribution to users; maintaining second portions of the data, associated with the first portions and substantially dynamic in nature, at a remote site for access by users via the wide area network; seeking from a user an identifier for the address in the respective local computer system of the distributed storage media, in response to a request for access to the data from the user; transmitting a first portion of the requested data from the remote site to the local computer system via the wide area network; and integrating the first portion of the data with a second portion of the data, from the storage media identified at the local computer system, for utilisation by the user.
- the production of the storage media includes the step of selecting from the data, staticfirst portions of data characterised by an insubstantial
- Suitably relatively large data files such as those relating to database tables, high resolution graphics, audio or video presentations and the like, are selected as static first data portions.
- the production of the storage media includes the further step of encrypting the first portions of the data in accordance with a predetermined key.
- the maintenance of the remote site includes the step of selecting from the data, dynamic second portions of data characterised by a substantial requirement for subsequent updating.
- Suitably relatively small data files such as relating to textual matter, low resolution graphics and the like, are selected as dynamic second data portions.
- the step of selecting the second portions of data may include the step of determining a key for encrypting first portions of the data.
- the portable storage media is distributed to users by physical delivery channels.
- the step of seeking from a user an identifier for the address of the distributed storage media is suitably performed in response to a request for data including at least a first portion of the data.
- the identifier is an address in the local computer system allocated to a drive means for reading the portable storage media.
- the dynamic data portions are replicated to facilitate integration with associated static data portions referenced by different identifiers allocated to drive means in the local computer system.
- the integrated data portions are immediately presented to the user at the local computer system.
- the invention resides in a system for disseminating data to users of local computer systems connectable to a wide area network, said system including: production means for producing storage media containing first portions of the data, which first portions are substantially static in nature, for distribution to the users; a remote site including a processor for processing the data and mass storage means for maintaining second portions of the data, which second portions are substantially dynamic in nature and associated with the first portions and; a plurality of local computer systems for respective users, each local computer system connectable to the remote site via the wide area network and including communications means for accessing second data portions from the remote site and drive means for reading the distributed storage media containing first data portions; whereby an identifier of an address of the drive means is communicated to the remote site and access to the second data portions by a user facilitates integration of a second data portion with an associated first data portion for utilisation by the user.
- the production means comprises a device for writing data to portable storage media.
- the production means are coupled to the processor at the remote site.
- the production means allows the encryption of the first data portions.
- the static first portions of the data are characterised by an insubstantial requirement for subsequent updating.
- the static first data portions include relatively large data files.
- the dynamic second portions of the data are characterised by a substantial requirement for subsequent updating.
- the dynamic second data portions include relatively small data files.
- dynamic data portions are replicated at the remote site to facilitate integration with associated static data portions referenced by different identifiers allocated to drive means in the local computer system.
- the local computer system integrates the data portions for immediate presentation to the user.
- the invention resides in a method for converting files for implementing a Web site from a first form suitable for unified data dissemination to a second form suitable for hybrid data dissemination, including the steps of: sorting the files according to whether they contain static data or dynamic data; arranging the static data files into a predetermined directory structure for writing to portable storage media; searching the dynamic files to identify references to static data files; modifying each reference to a static data file in the dynamic files in accordance with the predetermined directory structure; replicating each reference to facilitate access to the static files by drive means having different identifiers allocated thereto; and incorporating all dynamic files together for publication on the Internet.
- FIG. 1 is a schematic diagram showing an overview of a data dissemination system of a first embodiment
- FIG. 2 is an overview of the steps involved in the hybrid data dissemination method of the embodiment
- FIG. 3 is a flow chart showing the steps involved in preparing and disseminating the data for to users.
- FIG. 4 is a flow chart of the main steps involved in accessing data using a method of the first embodiment.
- remote site 10 including a server 11 which may be operated in accordance with a method for disseminating digital data to a plurality of users 20.
- the remote server 11 includes a display unit 12, a processor unit 13, a keyboard 14, a mass storage device 15 (such as a fixed magnetic disc) and a CD-ROM read/write device 16.
- Each of the users has a local computer system 21 , 22, 23 interconnected with the server 11 via a wide area network 30.
- each of the interconnections makes use of a respective voice channel 31 , 32, 33 provided by the public switched telephone network (PSTN).
- PSTN public switched telephone network
- the interconnections are typically a pair of wires, although the present invention envisages use in relation to networks including radio transmission for fixed local loop or mobile telephone channels.
- a typical example of this arrangement is that individual users connect to the site of an Internet service provider (ISP) 34 via the PSTN.
- ISP Internet service provider
- the ISP provides a gateway to higher speed communications channels in the network, such as the high speed channel 35 between ISP 36 and the processor at the remote site 10.
- the digital data for dissemination relates to information in a sales catalog for products available for purchase from a vendor by users.
- the vendor also happens to operate the remote site 10.
- the sales catalog contains numerous audio-visual presentations and demonstrations of the available products along with text based information providing current pricing information, product availability information and optionally allowing individual users to place orders for selected products.
- the data for dissemination may thus be conveniently divided into two categories:
- a first category of data portions which are substantially "static” in nature such as files containing the audio visual presentations and product demonstrations, typically involving large files sized from around one megabyte to hundreds of megabytes
- a second category of data portions which are substantially “dynamic” in nature such as files containing the text based information relating to pricing, availability and ordering or smaller images, typically involving files sized below about one megabyte.
- static and dynamic relate to the relative desirability of amending the information from time to time.
- price and availability information may require updating on a weekly, daily or even hourly basis - depending on the nature of the product; whereas the functional details of a product line are generally subject to a relatively insubstantial requirement for updating.
- information supplied by the vendor can be distributed to users in a hybrid manner which takes advantage of the particular mode of distribution of the digital data.
- the static data can be compiled and transferred onto storage media, such as a CD-ROM 40, which is capable of reliably storing a large amount of data.
- a CD-ROM read/write device 12 coupled to the remote server 11 may be used for this purpose.
- the CD-ROM may then be reproduced and distributed to users either free of charge as a marketing exercise, noting that the unit cost of reproducing CD-ROMs is of the order of one dollar, or sold in response to user requests.
- the reproduction and distribution of the CD-ROMs is undertaken by a separate entity 17 contracted for this purpose in the embodiment.
- the physical distribution channels such as delivery by the postal service, are represented by dashed lines in the drawing figure.
- the dynamic data which is subject to a substantial requirement for updating, is maintained at the vendor site 10.
- the dynamic data is stored in a secondary memory device, such as the magnetic disc 15, for direct access by users 20 via the network 30. It will be appreciated that a change in pricing of certain products can be made available to users as soon as the price information held on the magnetic disc in the remote server 11 can be updated.
- a product vendor or service provider may chose to produce and replicate their own CD-ROMs containing the static data, but rely on an Internet service provider (ISP) 34 to mount the dynamic data on a mass storage device attached to the ISP's server. Any amendments to the dynamic data would then be forwarded to the ISP for consequential updates.
- ISP Internet service provider
- the static data on the CD-ROM may also include promotional material for potential future product releases. It will be appreciated that the dynamic data would require only minor changes to introduce pricing information and allow access to the relevant files on the CD-ROM at the time of the product launch.
- the source code 51 for a Internet site and particularly a World Wide Web (www or "Web") site is generally coded in hyper text mark-up language (HTML).
- the source code typically assumes that all of the data will be unified in a set of files accessible at the site.
- a conversion process 52 discussed below in relation to FIG.3, is provided for converting code from standard Internet code to modified Internet code suitable for hybrid distribution of data. The process separates, in accordance with configuration settings determined by the site manager or 'web master', the static data from the dynamic data.
- the static data 53 is written to portable storage media, such as a CD-ROM, for distribution to selected users via physical delivery channels.
- the dynamic data 54 includes the modified Internet code which is hosted at a remote site. When a user in possession of a distributed CD-ROM accesses the site, the portions of dynamic and static data may be integrated 56 for presentation to the user, as described below in relation to FIG. 4.
- the conversion process 60 begins with all files 61 for a pre-existing Web site.
- the files are then sorted 62 in accordance with whether they are static data files on the one hand or dynamic data files on the other.
- the process in this example has been configured such that all files with extensions *.jpg, *.gif, *.mpg *.avi and * .wav characteristic of image, audio and video data are sorted as static files; whilst text and Internet code files (*.htm, *.vmr *.txt and *.doc) are sorted as dynamic files.
- the static data files are then stored 63 in a suitable directory structure, where similar type files may be grouped together, from where they may be copied to portable storage media as required. Subsequently, copies of the media can be delivered 64 to users.
- the dynamic files 65 are each searched 66 to determine whether they reference any of the static data files identified at step 62.
- the path reference to each file in the source code is then modified in accordance with the directory structure provided at step 63.
- All dynamic files that refer to static content are replicated 68 and saved for all valid media drive letters, generally A through Z.
- the replicated files are incorporated 69 with the files which lack references and the dynamic data is published on the Internet 70.
- FIG. 4 illustrates a flow chart including the steps taken by a user to access the sales catalog example of the embodiment.
- the flow chart assumes that the user in question has received a distributed CD-ROM 41 , containing the static data portions of the product information from the vendor, via the postal service.
- the users local computer system 21 includes a suitable CD-ROM drive 24 and general purpose communications software including an Internet browser, whether in the form of a dedicated application (such as Microsoft's Internet ExplorerTM or Netscape's NavigatorTM suites) or embedded in the computer's operating system.
- the user connects 71 to the vendor's remote server 11 using the browser software and internal modem 26.
- the connection includes a voice channel 31 on the PSTN between the local computer system 21 and an ISP 34.
- the welcome page includes text requesting that the user select the desired mode to view the subsequent pages with product information, one selection is identified as a "CD Enhanced" mode. If the CD Enhanced mode is selected, the user is asked for a letter or other identifier which designates the address of the CD-ROM drive 24 in the local computer system to be entered 74.
- the selections available are any one of the letters D through Z, as many personal computers have a magnetic disc drive assigned the letter C and the next available letter D assigned to the CD-ROM drive.
- the situation becomes complicated where there are a number of drives for storage media, whether logical or physical, which may be potentially identified. A typical example is when the user's computer system involves a local area network with multiple drives.
- the dynamic data on the remote server 11 is preferably arranged according to a particular hierarchical structure.
- a common file containing the welcome page is contained in an upper directory of the remote server's magnetic disc 15 and lower directories are separated into 26 identically structured subdirectories.
- Each subdirectory contains almost identical sets of generally text based web pages, the only difference amongst the sets being the referencing of different drive letters for selection of static data files contained on the CD-ROM in the local drive.
- HTML hyper text mark-up language
- a selection 75 of "F" by the user links to the set of pages arranged for that drive identifier, which pages contain the dynamic data comprising the catalog information.
- all subsequent references made to the storage device may be done using a HTML string which points to a file.
- the calls to dynamic data files containing pictures, audio-visual presentations, movies, etc. from within the HTML code preferably uses a string constant "file:///x ⁇ /' at the start of the file path.
- " can be changed to to point to the CD- ROM drive. This string reflects each replicated Web page and the variable "at7ydr/Ve
- the requested dynamic data is sent 76 to the local computer system for display 77.
- a default product listing is displayed with options for product demonstrations, ie. portions of the dynamic data are associated with portions of static data. If the demonstration video for a particular product was requested by the user, the appropriate mpg file contained on the CD-ROM in the F drive of the local machine would be activated 80 to display the video. Further user requests 81 are then handled on the basis of whether static or dynamic data is required. This process may be contrasted with prior art arrangements (shown in the inset to FIG. 4) whereby a lengthy video file would first need to be accessed 82 at the remote server and then sent 83 over the communications network to the local computer system prior to be ready for display. Typically an image or audio-visual presentation is displayed in a window in a predetermined position on the user's display unit 25.
- the method of the embodiment is thus largely non-invasive in that the user is not required to load vendor specific software nor down-load any active code which may, with or without the users permission, interrogate sensitive system files which can potentially compromise the user's privacy.
- the appropriate file contained on the distributed CD-ROM may be accessed directly via F drive for integration with the dynamic data.
- the static data on the storage media may be encrypted to prevent unauthorised access, the dynamic data would include a decryption key and the step of integrating the data portions would involve decrypting the static data portions for presentation.
- This arrangement can substantially reduce the time a user might otherwise spend awaiting a large file to be down-loaded from the remote server.
- the sales catalog includes current price and availability information as this dynamic data, principally textual in nature is obtained from the remote server.
- the access and presentation speed of a local CD-ROM or similarly performing storage media is combined with the currency of information provided to users 20 directly from the vendor's site 10.
- use of a search engine on the Internet generally delivers hundreds of potential vendors, which must be carefully sifted.
- the product presentations facilitated by the mailed CD- ROM are fast and efficient and represent reduced risk for the user.
- the method of the invention has numerous other applications.
- all the pictures, sounds, video and bulk textual data ie. reference materials
- Students could then log into a remote server at a learning site where suitable dynamic data files, for example HTML pages, embodying a program of study in accordance with a predetermined curriculum.
- suitable dynamic data files for example HTML pages, embodying a program of study in accordance with a predetermined curriculum.
- the static data could include sensitive records for individuals (for example medical or financial records) which could distributed without identification to potential users.
- the identification information could be stored as dynamic information at a secure site, whereby authorised users could only access certain identification information in accordance with their level of authority. Encryption of static data could also be employed as desired.
