Method and system for look data definition and transmission over a high definition multimedia interface

1. A method, comprising:

generating metadata for video content, the metadata for altering the video content before display thereof by accounting for variations between different display devices and variations between different creative intents by a content creator; and

preparing the video content and the metadata for transmission over a high definition multimedia interface using a gamut profile of a gamut boundary description metadata container to convey the metadata for altering the video content.

2. The method of claim 1 , further comprising transmitting the metadata and the video content over the high definition multimedia interface, such that the metadata is available to alter the video content before the display thereof.

3. The method of claim 1 , wherein the metadata is prepared for the transmission at least one of in-band and out-of-band with respect to the video content.

4. The method of claim 1 , wherein the metadata is prepared for the transmission using at least one of a new gamut profile and an unused gamut profile of a gamut boundary description metadata container with respect to version 1.3A and any earlier versions of the High Definition Multimedia Interface Specification.

5. The method of claim 1 , wherein the metadata is prepared for the transmission using a vendor specified information frame.

6. The method of claim 5 , wherein said preparing step comprises applying gamut boundary description flow control to the vendor specified information frame.

7. The method of claim 1 , wherein the metadata is prepared for the transmission using a high definition multimedia interface consumer electronics control protocol.

8. The method of claim 7 , wherein said preparing step comprises at least one of adding a network abstraction layer on top of the consumer electronics control protocol and enabling quality of service.

9. The method of claim 7 , wherein said preparing step comprises timing the consumer electronics control protocol to the video content including coupling the consumer electronics control protocol with a vertical synchronization signal.

10. The method of claim 1 , wherein the metadata is for at least one of color manipulation of the video content, controlling spatial filtering of the video content to change a modulation transfer function associated therewith, controlling a motion behavior of the video content, controlling a film grain aspect of the video content, adding noise to the video content, controlling an editorial of a scene in the video content, and tone mapping with respect to the video content.

11. The method of claim 10 , wherein the metadata corresponds to at least one of one or more look up tables and one or more color transform matrices.

12. The method of claim 1 , wherein said preparing step comprises organizing the metadata into a packet.

13. The method of claim 12 , further comprising generating at least one message for inserting in the packet, the at least one message relating to at least one of color manipulation of the video content, controlling spatial filtering of the video content to change a modulation transfer function associated therewith, controlling a motion behavior of the video content, controlling a film grain aspect of the video content, adding noise to the video content, controlling an editorial of a scene in the video content, and tone mapping with respect to the video content.

14. The method of claim 1 , further comprising storing the video content and the metadata on a disk for subsequent display of the video content modified in accordance with the metadata.

15. A system, comprising:

a metadata generator for generating metadata for video content, the metadata for altering the video content before display thereof by accounting for variations between different display devices and variations between different creative intents by a content creator; and

a metadata transmission preparation device for preparing the video content and the metadata for transmission over a high definition multimedia interface using a gamut profile of a gamut boundary description metadata container to convey the metadata for altering the video content.

16. The system of claim 15 , further comprising a high definition multimedia interface transmission device for transmitting the metadata and the video content over the high definition multimedia interface, such that the metadata is available to alter the video content before the display thereof.

17. The system of claim 15 , wherein the metadata is prepared for the transmission at least one of in-band and out-of-band with respect to the video content.

18. The system of claim 15 , wherein the metadata is prepared for the transmission using at least one of a new gamut profile and an unused gamut profile of a gamut boundary description metadata container with respect to version 1.3A and any earlier versions of the High Definition Multimedia Interface Specification.

19. The system of claim 15 , wherein the metadata is prepared for the transmission using a vendor specified information frame.

20. The system of claim 19 , wherein gamut boundary description flow control is applied to the vendor specified information frame.

21. The system of claim 15 , wherein the metadata is prepared for the transmission using a high definition multimedia interface consumer electronics control protocol.

22. The system of claim 21 , wherein said metadata transmission preparation device at least one of adds a network abstraction layer on top of the consumer electronics control protocol and enables quality of service.

23. The system of claim 22 , wherein said metadata transmission preparation device times the consumer electronics control protocol to the video content including coupling the consumer electronics control protocol with a vertical synchronization signal.

24. The system of claim 15 , wherein the metadata is for at least one of color manipulation of the video content, controlling spatial filtering of the video content to change a modulation transfer function associated therewith, controlling a motion behavior of the video content, controlling a film grain aspect of the video content, adding noise to the video content, controlling an editorial of a scene in the video content, and tone mapping with respect to the video content.

25. The system of claim 24 , wherein the metadata corresponds to at least one of one or more look up tables and one or more color transform matrices.

26. The system of claim 15 , wherein the metadata is organized into a packet.

27. The system of claim 26 , wherein the packet comprises at least one message relating to at least one of color manipulation of the video content, controlling spatial filtering of the video content to change a modulation transfer function associated therewith, controlling a motion behavior of the video content, controlling a film grain aspect of the video content, adding noise to the video content, controlling an editorial of a scene in the video content, and tone mapping with respect to the video content.

28. The system of claim 15 , further comprising a storage device for storing the video content and the metadata on a disk for subsequent display of the video content modified in accordance with the metadata.
