Abstract

A method of adaptive transmission of data between a data transmission device and at least one data accessing device comprising, the steps of receiving a request from the data accessing device for data; determining a user environment of the data accessing device and transmitting the user environment back to the data transmission device, wherein the user environment comprises information corresponding to a data access and display software of the data accessing device, adapting a format and a level of functionality of the data to account for the user environment to produce adapted data, and transmitting the adapted data to the data accessing device. The user environment may also comprise information about a rendering engine and a platform.

Claims

1. A method of adaptive transmission of data between a data transmission device and at least one data accessing device, comprising in combination, the steps of:

receiving a request for data from the data accessing device;

determining a user environment of the data accessing device and transmitting the user environment back to the data transmission device,

wherein the user environment comprises information corresponding to a data access and display software of the data accessing device;

adapting a format and a level of functionality of the data to account for the user environment to produce adapted data; and

transmitting the adapted data to the data accessing device.

2. The method of adaptive transmission of claim 1 wherein the user environment further comprises information corresponding to a platform of the data accessing device.

3. The method of adaptive transmission of claim 2 wherein the platform is one of a mobile computer and a personal computer.

4. The method of adaptive transmission of claim 1 wherein the format of the data comprises one of a raster format, a vector format, and a mixed raster/vector format.

5. The method of adaptive data transmission of claim 4 wherein the vector format is produced pursuant to a Scalable Vector Graphics standard.

6. The method of adaptive data transmission of claim 1 wherein the level of functionality of the data comprises at least one of color gradients, graphic clipping, graphic filters, scripting, stroke, interactivity, animation, metadata and basic shapes.

7. The method of adaptive data transmission of claim 1 wherein the data is graphical data.

8. The method of adaptive data transmission of claim 1 wherein the data access and display software comprise an operating system and a web browser.

9. A method of adaptive transmission of data between a data transmission device and at least one data accessing device comprising, in combination, the steps of:

receiving a request for data from the data accessing device;

determining a user environment of the data accessing device and transmitting the user environment back to the data transmission device,

wherein the user environment comprises a capability of a rendering engine;

adapting a format and a level of functionality of the data to account for the user environment to produce adapted data; and

transmitting the adapted data to the data accessing device.

10. The method of adaptive transmission of claim 9 wherein the rendering engine is one of a plug-in and incorporated as a part of a browser, and is adapted to render scalable vector graphics.

11. The method of adaptive transmission of claim 9 wherein the user environment capability comprises a profile and a level of conformance.

12. The method of adaptive transmission of claim 11 wherein the profile is one of SVG Full, SVG Tiny, and SVG Basic.
