Abstract

A data processor controlled display system for displaying documents including natural language text representative of data transmitted in a markup language such as HTML to a display station from a location remote from said station. The HTML tags are tokenized prior to transmission, comments are removed from the HTML file prior to transmission and the file is then subjected to a conventional general text compression. After the HTML file is received at the display station, it is decompressed, detokenized and the resulting HTML file is used to create a document or page on the display.

Claims

1. In a data processor controlled display system for displaying documents including natural language text representative of data transmitted to display stations from a location remote from said stations,

means at said remote location for storing said data in a markup language format including tags identifying the contents of said data,

means for tokenizing only said tags,

means for transmitting said data including said tokenized tags to at least one of said display stations,

means for detokenizing said tokenized tags received at said one display station whereby said received data is restored to said markup language format, and

means associated with said display station for translating said received data from said markup language format into said displayed natural language text documents.

2. The data processor controlled display system of claim 1 wherein said markup language is Hypertext Markup Language (HTML).

3. The data processor controlled display system of claim 2 wherein said stored data includes data portions identified by said tags as comments and said system further includes

means for removing said data portions identified as comments prior to transmitting said data.

4. The data processor controlled display system of claim 3 further including

general data compression means for compressing, prior to said transmitting, the data portions remaining after comments removal, and

means for decompressing said compressed data portions received at said one display station whereby said received data is restored to said markup language format.

5. A computer implemented method for displaying documents including natural language text representative of data transmitted to display stations from a location remote from said stations comprising:

storing at said remote location said data in a markup language format including tags identifying the contents of said data,

tokenizing only said tags,

transmitting said data including said tokenized tags to at least one of said display stations,

detokenizing said tokenized tags received at said one display station whereby said received data is restored to said markup language format, and

translating said received data from said markup language format into said displayed natural language text documents.

6. The method of claim 5 wherein said markup language is Hypertext Markup Language (HTML).

7. The method of claim 6 wherein said stored data includes data portions identified by said tags as comments and including the further step of

removing said data portions identified as comments prior to transmitting said data.

8. The method of claim 7 further including

the step of performing a general data compression, prior to said transmitting, on the data portions remaining after comments removal, and

decompressing said compressed data portions received at said one display station whereby said received data is restored to said markup language format.

9. A computer program having data structures included on a computer readable said program being for transmission and display of documents including natural language text representative of data transmitted to display stations from a location remote from said stations and comprising:

means at said remote location for storing said data in a markup language format including tags identifying the contents of said data,

means for tokenizing only said tags,

means for transmitting said data including said tokenized tags to at least one of said display stations,

means for detokenizing said tokenized tags received at said one display station whereby said received data is restored to said markup language format, and

means associated with said display station for translating said received data from said markup language format into said displayed natural language text documents.

10. The computer program according to claim 9, wherein said markup language is Hypertext Markup Language (HTML).

11. The computer program according to claim 10 wherein said stored data includes data portions identified by said tags as comments and said system further includes

means for removing said data portions identified as comments prior to transmitting said data.

12. The computer program according to claim 11 further including

general data compression means for compressing, prior to said transmitting, the data portions remaining after comments removal, and

means for decompressing said compressed data portions received at said one display station whereby said received data is restored to said markup language format.
