Abstract

Methods for streaming web content data via a computer-readable medium. The web content data comprises one or more media samples. The media samples are encoded in a streaming media format as a web component stream. The web component stream is combined with other component streams comprising additional data other than web content data into a presentation stream. The presentation stream is transmitted via a media server to a client. Rendering commands, which are included in one or more rendering samples encoded in the web component stream along with the media samples, coordinate synchronization between the media samples and the additional data when the client renders the presentation stream.

Claims

1. A method for rendering a web component stream on a client, said method comprising:

requesting, by the client, a rendering point in a timeline of a presentation, said presentation comprising the web component stream, wherein the web component stream is stored on a computer-readable medium wherein the requested rendering point represents a clean point;

receiving, by the client, the web component stream from the computer-readable medium, wherein said web component stream is received as part of a presentation stream or presentation file, said web component stream including a plurality of media samples corresponding to the requested rendering point;

retrieving, by the client, the plurality of media samples from the web component stream into a cache;

receiving, by the client, a rendering time for the plurality of media samples;

retrieving, by the client, the plurality of media samples from the cache; and

rendering, by the client, the retrieved media samples as a function of the received rendering time, wherein said retrieving of the media sample from the cache comprises referencing the media sample to be retrieved by appending a custom protocol identifier to a uniform resource locator of the media sample, said custom protocol restricting a renderer to search for the media sample only in the cache.

2. The method of claim 1, wherein said media sample is retrieved from the web component stream and stored in the cache piece by piece, wherein each piece of said media sample comprises a header, said header comprising a tag indicating that said piece is part of said media sample.

3. The method of claim 1, further comprising retrieving additional data other than web content data from the presentation stream or presentation file and rendering said additional data.

4. The method of claim 1, further comprising receiving a rendering command relating to the media sample and coordinating a rendering time for the media sample by the received rendering command.

5. The method of claim 4, further comprising coordinating synchronization between the media sample and additional data other than web content data by the received rendering command.

6. The method of claim 1, wherein one or more computer-readable media have computer-executable instructions for performing the method of claim 1.

15. The method of claim 1, wherein retrieving includes retrieving, by the client computer from the received web component stream, only the plurality of media samples corresponding to the requested rendering point.

7. A system for rendering a web component stream comprising:

a client computer comprising a processor configured to execute computer-executable instructions stored on a computer readable storage media, said computer-executable instructions comprising instructions for;

providing, by the client computer, a request for a portion of a presentation, said request including a rendering point in a timeline of the presentation, said presentation comprising a web component stream stored on a computer-readable medium wherein the requested rendering point represents a clean point;

receiving, by the client computer, the web component stream from the computer-readable medium, said web component stream including a plurality of media samples corresponding to the requested rendering point;

retrieving, by the client computer from the received web component stream, the plurality of media samples corresponding to the requested rendering point into a cache;

retrieving the plurality of media samples from the cache; and

rendering the retrieved media samples, wherein said retrieving of the media sample from the cache comprises referencing the media sample to be retrieved by appending a custom protocol identifier to a uniform resource locator of the media sample, said custom protocol restricting a renderer to search for the media samples only in the cache.

8. The system of claim 7, further comprising computer-executable instructions for storing the media sample in a cache.

9. The system of claim 8, wherein said media sample is retrieved from the web component stream and stored in the cache piece by piece, wherein each piece of said media sample comprises a header, said header comprising a tag indicating that said piece is part of said media sample.

10. The system of claim 7, further comprising computer-executable instructions for receiving a rendering time for the media sample, retrieving the media sample from the cache, and rendering the retrieved media sample as a function of the received rendering time of the media sample, wherein said retrieving of the media sample from the cache comprises referencing the media sample to be retrieved by appending a custom protocol to a uniform resource locator of the media sample, said custom protocol restricting a renderer to search for the media sample only in the cache.

11. The system of claim 7, further comprising computer-executable instructions for retrieving additional data other than web content data from the presentation stream or presentation file and rendering said additional data.

12. The system of claim 7, further comprising computer-executable instructions for receiving a rendering command relating to the media sample and coordinating a rendering time for the media sample by the received rendering command.

13. The system of claim 12, further comprising computer-executable instructions for coordinating synchronization between the media sample and additional data other than web content data by the received rendering command.

14. The system of claim 7, wherein the computer-executable instructions are stored on one or more computer-readable media.

16. The system of claim 7, wherein retrieving includes retrieving, by the client computer from the received web component stream, only the plurality of media samples corresponding to the requested rendering point.
