Abstract

A method of embedding vector graphics content such as SVG into the 3GPP ISO Base Media File Format for progressive downloading or streaming of live rich media content over MMS/PSS/MBMS services. The method of the present invention allows the file format to be used for the packaging of rich media content including graphics, video, text and images; enables streaming servers to generate RTP packets; and enables clients to realize, play, or render rich media content.

Claims

1. A method of progressively providing rich media content to a client device, comprising:

providing rich media content including SVG;

creating an ISO Base Media File from the rich media content using an ISO Base Media Generator;

encoding the ISO Base Media File; and

transmitting the encoded ISO Base Media file in a plurality of packets to the client device.

2. The method of claim 1, further comprising:

upon reaching the client device, decoding the encoded ISO Base Media file; and

extracting the ISO Base Media file.

3. The method of claim 1, wherein the ISO Base Media File includes an SVG media track describing media objects contained within the ISO Base Media File.

4. The method of claim 3, wherein the SVG media track includes a sample table box containing time and data indexing for the media samples contained within the SVG media track.

5. The method of claim 3, wherein the SVG media track includes a sample description box containing information specific to a media sample.

6. The method of claim 3, wherein the SVG media track includes a decoding time-to-sample box, the decoding time-to-sample box specifying the decoding time for each media sample within the SVG media track.

7. The method of claim 1, wherein the ISO Base Media File includes a hint track sample, the hint track sample either containing or pointing to data that is to be sent in each packet.

8. The method of claim 1, wherein the ISO Base Media File includes a shadow sync table, the shadow sync table including samples that are used to support random access.

9. A method of progressively providing rich media content to a client device, comprising:

computer code for providing rich media content including SVG;

computer code for creating an ISO Base Media File from the rich media content using an ISO Base Media Generator;

computer code for encoding the ISO Base Media File; and

computer code for transmitting the encoded ISO Base Media File in a plurality of packets to the client device.

10. The computer program product of claim 9, further comprising:

computer code for, upon reaching the client device, decoding the encoded ISO Base Media File; and

computer code for extracting the ISO Base Media file.

11. The computer program product of claim 9, wherein the ISO Base Media File includes an SVG media track describing media objects contained within the ISO Base Media File.

12. The computer program product of claim 11, wherein the SVG media track includes a sample table box containing time and data indexing for the media samples contained within the SVG media track.

13. The computer program product of claim 11, wherein the SVG media track includes a sample description box containing information specific to a media sample.

14. The computer program product of claim 11, wherein the SVG media track includes a decoding time-to-sample box, the decoding time-to-sample box specifying the decoding time for each media sample within the SVG media track.

15. The computer program product of claim 9, wherein the ISO Base Media File includes a hint track sample, the hint track sample either containing or pointing to data that is to be sent in each packet.

16. The computer program product of claim 9, wherein the ISO Base Media File includes a shadow sync table, the shadow sync table including samples that are used to support random access.

17. An electronic device, comprising:

a processor; and

a memory unit operatively connected to the processor and including;

computer code for providing rich media content including SVG;

computer code for creating an ISO Base Media File from the rich media content using an ISO Base Media Generator;

computer code for encoding the ISO Base Media File; and

computer code for transmitting the encoded ISO Base Media file in a plurality of packets to the client device.

18. The electronic device of claim 17, wherein the ISO Base Media File includes an SVG media track describing media objects contained within the ISO Base Media File.

19. The electronic device of claim 17, wherein the ISO Base Media file includes a hint track sample, the hint track sample either containing or pointing to data that is to be sent in each packet.

20. The electronic device of claim 17, wherein the ISO Base Media File includes a shadow sync table, the shadow sync table including samples that are used to support random access.
