Abstract

Aspects of a method and system for providing visually related content description to physical layer are provided. A MAC layer and/or a PHY layer in a wireless communication device may be controlled for processing at least one media object in an audiovisual scene based on metadata information that corresponds to the audiovisual scene. The metadata information may result from, for example, MPEG-4 encoding of the audiovisual scene. Each media object may be forward error corrected based on a determined priority level, such as foreground and background priorities, that results from the metadata information. In this regard, the number of bits utilized for protection and/or the RF modulated scheme may be selected in accordance with the priority level. The RF modulation may be, for example, QPSK modulation or 16 QAM modulation. The metadata information and the processed media objects may then be wireless communicated.

Claims

1. A method for handling data in a communication system, the method comprising:

controlling at least one of;

a MAC layer and a PHY layer, in a wireless communication device for processing at least one media object in an audiovisual scene based on metadata information corresponding to said audiovisual scene; and

wirelessly communicating said metadata information and said processed at least one media object in said audiovisual scene.

2. The method according to claim 1, comprising determining a priority level for said at least one media object in said audiovisual scene.

3. The method according to claim 2, comprising FEC coding each of said at least one media object in accordance with said determined priority level.

4. The method according to claim 2, comprising RF modulating each of said at least one media object in accordance with said determined priority level.

5. The method according to claim 4, wherein said RF modulating is QPSK modulation.

6. The method according to claim 4, wherein said RF modulating is 16 QAM modulation.

7. The method according to claim 1, wherein said audiovisual scene is an MPEG-4 audiovisual scene.

8. A machine-readable storage having stored thereon, a computer program having at least one code section for handling data in a communication system, the at least one code section being executable by a machine for causing the machine to perform steps comprising:

controlling at least one of;

a MAC layer and a PHY layer, in a wireless communication device for processing at least one media object in an audiovisual scene based on metadata information corresponding to said audiovisual scene; and

wirelessly communicating said metadata information and said processed at least one media object in said audiovisual scene.

9. The machine-readable storage according to claim 8, comprising code for determining a priority level for said at least one media object in said audiovisual scene.

10. The machine-readable storage according to claim 9, comprising code for FEC coding each of said at least one media object in accordance with said determined priority level.

11. The machine-readable storage according to claim 9, comprising code for RF modulating each of said at least one media object in accordance with said determined priority level.

12. The machine-readable storage according to claim 11, wherein said RF modulating is QPSK modulation.

13. The machine-readable storage according to claim 11, wherein said RF modulating is 16 QAM modulation.

14. The machine-readable storage according to claim 8, wherein said audiovisual scene is an MPEG-4 audiovisual scene.

15. A system for handling data in a communication system, the system comprising:

circuitry within a wireless communication device that enables controlling at least one of;

a MAC layer and a PHY layer, in said wireless communication device for processing at least one media object in an audiovisual scene based on metadata information corresponding to said audiovisual scene; and

said circuitry enables wirelessly communicating said metadata information and said processed at least one media object in said audiovisual scene.

16. The system according to claim 15, wherein said circuitry enables determining a priority level for said at least one media object in said audiovisual scene.

17. The system according to claim 16, wherein said circuitry enables FEC coding each of said at least one media object in accordance with said determined priority level.

18. The system according to claim 16, wherein said circuitry enables RF modulating each of said at least one media object in accordance with said determined priority level.

19. The system according to claim 18, wherein said circuitry enables modulating using QPSK modulation.

20. The system according to claim 18, wherein said circuitry enables modulating using 16 QAM modulation.

21. The system according to claim 15, wherein said audiovisual scene is an MPEG-4 audiovisual scene.
