Abstract

A data processor controlled user interactive display system for displaying hypertext documents, each including a sequence of display screen pages received over a communications network such as the World Wide Web. In order to reduce downloading time, Web pages are transmitted as HTML files in which images are represented by identifiers. The images corresponding to the identifiers may be fetched from libraries of universal images. The invention is implemented by the display stations which receive the Web pages. These stations, through associated browsers, retrieve the universal image libraries via the internet and download such libraries once and store them locally on caches associated with the browsers.

Claims

1. In a computer managed communication network with user access via a plurality of data processor controlled interactive display stations and with a system for displaying documents transmitted to said display stations from locations remote from said stations, said documents including a sequence of at least one display screen page including images, the improvement comprising:

means for transmitting to a receiving one of said display stations, a page comprising at least one identifier representative of a universal image,

a library of universal images and identifiers respectively representative of each of said images at a location remote from said receiving display station,

a network library server for fetching said library and for transmitting said library to said receiving display station, and

means associated with said receiving display station for retrieving from said library the image represented by said one identifier, whereby said retrieved image is included in said page.

2. The communications network of claim 1 wherein said receiving display station further includes a user interactive network browser, said browser including said means for retrieving said image from said library.

3. The communications network of claim 2, further including a cache associated with said receiving display station for storing said received library whereby said browser may retrieve said image from said cache.

4. The communications network of claim 1 wherein said universal images are images of symbols.

5. The communications network of claim 1 further including a facility for the creation of said display screen pages wherein said library server also operates to fetch said library and transmit said library to said display page creation facility, said facility comprising:

means for retrieving images and identifiers from said library of universal images,

means for incorporating selected images into said pages, and

means for transmitting said pages with said identifiers representative of said selected images in place of the images.

6. The communications network of claim 5, further including a cache associated with said display page creation facility for storing said received library whereby said facility may retrieve said image and identifiers from said cache.

7. In a computer managed communication network with user access via a plurality of data processor controlled interactive display stations and with a system for displaying documents transmitted to said display stations from locations remote from said stations, said documents including a sequence of at least one display page containing text and images, a method for facilitating the creation and transmission of said images comprising:

transmitting to a receiving one of said display stations, a page comprising at least one identifier representative of a universal image,

providing a library of universal images and identifiers respectively representative of each of said images at a location remote from said receiving display station,

fetching said library and transmitting said library to said receiving display station, and

retrieving at said receiving display station the image represented by said one identifier from said library, whereby said retrieved image is included in said received page.

8. The method of claim 7 further including a network browsing method carried out on said receiving display station, said browsing method including said step of retrieving said image from said library.

9. The method of claim 7, further including the step of caching the received library at said receiving display station whereby said image may be retrieved from said cache.

10. The method of claim 7 wherein said universal images are images of symbols.

11. The method of claim 7 further including a procedure for the creation of said display screen pages comprising:

accessing said library of universal images,

retrieving images and identifiers from said library of universal images,

incorporating selected images into said pages, and

transmitting said pages with said identifiers representative of said selected images in place of the images.

12. The method of claim 11 wherein said creation of said display pages includes the further step of caching said library whereby the library is available for the page creation.

13. In a computer program having data structures included on a computer readable medium for browsing a computer managed communication network via a data processor controlled user interactive receiving display station in order to display on said receiving display station, documents transmitted to said station from network locations remote from said receiving station, each document including a sequence of at least one display screen page containing text and images, the improvement comprising:

means for receiving at said receiving display station, a page comprising at least one identifier representative of a universal image,

means for fetching and transmitting to said receiving station from a remote location on said network, a library of universal images and identifiers respectively representative of each of said images, and

means for retrieving from said library the image represented by said one identifier, whereby said retrieved image is included in said page.

14. The computer program for browsing according to claim 13 wherein the means for accessing said library includes means for receiving at said display station, said library transmitted from a network library server.

15. The computer program for browsing according to claim 14, further including a cache at said receiving display station for storing said received library whereby said image may be retrieved from said cache.
