Abstract

Methods and apparatuses for processing media data transmitted in a data communication medium. A digital processing system is provided with a time related sequence of media data provided to the digital processing system based on a set of data, wherein the set of data indicates a method to transmit the time related sequence of media data according to a transmission protocol. The set of data, itself, is a time related sequence of data associated with the time related sequence of media data. The time related sequence of media data may be presented and/or stored by the digital processing system.

Claims

1. A method implemented by a digital processing system to process media data, said method comprising:

receiving at said digital processing system a time related sequence of media data provided to said digital processing system based on a set of data, wherein said set of data indicates a method to transmit said time related sequence of media data according to a transmission protocol, and wherein said set of data is a time related sequence of data associated with said time related sequence of media data; and

presenting at said digital processing system a media sequence associated with said time related sequence of media data.

2. The method of claim 1, wherein said set of data is associated with a track of indicating data, and wherein said transmission protocol comprises a packet data protocol.

3. The method of claim 1, further comprising:

receiving packets of data representing said time related sequence of media data, said packets provided to said digital processing system according to said transmission protocol.

4. The method of claim 3, further comprising:

presenting a media object represented by said time related sequence of media data as said packets of data are received at said digital processing system.

5. The method of claim 3, wherein for each of said packets, said set of data refers to data in at least one of a sequence of image data and a sequence of audio data.

6. The method of claim 1, further comprising:

storing said time related sequence of media data.

7. A method implemented by a digital processing system to process media data, said method comprising:

receiving at a digital processing system a time related sequence of media data provided to said digital processing system based on a set of data, wherein said set of data indicates a method to transmit said time related sequence of media data according to a transmission protocol, and wherein said set of data is a time related sequence of data associated with and separate from said time related sequence of media data; and

storing, in a storage area coupled to said digital processing system, said time related sequence of media data.

8. The method of claim 7, wherein said set of data is associated with a track of indicating data, and wherein said transmission protocol comprises a packet data protocol.

9. The method of claim 7, further comprising:

receiving packets of data representing said time related sequence of media data, said packets provided to said digital processing system according to said transmission protocol.

10. The method of claim 9, further comprising:

presenting a media object represented by said time related sequence of media data as said packets of data are received at said digital processing system.

11. The method of claim 9, wherein for each of said packets, said set of data refers to data in at least one of a sequence of image data and a sequence of audio data.

12. The method of claim 7, further comprising:

presenting at said digital processing system said at least one of a sequence of image data and a sequence of audio data represented by said time related sequence of media data.

13. A machine readable medium containing executable program instructions, which when executed on a digital processing system cause the digital processing system to perform a method comprising:

retrieving at said digital processing system a time related sequence of media data provided to said digital processing system based on a set of data, wherein said set of data indicates a method to transmit said time related sequence of media data to said digital processing system according to a transmission protocol, and wherein said set of data is a time related sequence of data associated with and separate from said time related sequence of media data; and

presenting at said digital processing system said time related sequence media data.

14. The machine readable medium of claim 13, wherein said set of data is associated with a track of indicating data, and wherein said transmission protocol comprises a packet data protocol.

15. The machine readable medium of claim 13, wherein said executable program instructions, when executed on said digital processing system, further cause said digital processing system to perform the method comprising:

receiving packets of data representing said time related sequence of media data, said packets provided to said digital processing system according to said transmission protocol.

16. The machine readable medium of claim 13, wherein said executable program instructions, when executed on said digital processing system, further cause said digital processing system to perform the method comprising:

presenting a media object represented by said time related sequence of media data in response to said packets of data being retrieved at said digital processing system.

17. The machine readable medium of claim 15, wherein for each of said packets, said set of data refers to data in at least one of a sequence of image data and a sequence of audio data.

18. The machine readable medium of claim 13, wherein said executable program instructions, when executed on said digital processing system, further cause said digital processing system to perform the method comprising:

storing information associated with a media object represented by said time related sequence of media data in response to said packets of data being retrieved at said digital processing system.
