Abstract

A removable storage media is received by and interacts with both a first video player system and a second video player system. The first video player system has a first video display that has a first display characteristic and the second video player system has a second video display that has a second display characteristic, the first display characteristic being different from the second display characteristic. The removable storage media includes a plurality of storage locations and stores a sequence of full frames of video data, first sub-frame metadata, and second sub-frame metadata. The first sub-frame metadata is generated and the second sub-frame metadata are used to process the full frames of video data to correspond to the first video display and the second video display, respectively.

Claims

1. A removable storage media that may be received by and interact with both a first video player system and a second video player system, the first video player system having a first video display that has a first display characteristic, the second video player system having a second video display that has a second display characteristic, the first display characteristic being different from the second display characteristic, the removable storage media comprising:

a plurality of storage locations;

a sequence of full frames of video data stored in at least a first of the plurality of storage locations;

first sub-frame metadata, generated to accommodate at least the first display characteristic, that is stored in at least a second of the plurality of storage locations;

the first sub-frame metadata defines a first plurality of sub-frames within the sequence of full frames of video data, each of the first plurality of sub-frames having at least a first parameter that differs from that of the other of the first plurality of sub-frames;

second sub-frame metadata, generated to accommodate at least the second display characteristic, that is stored in at least a third of the plurality of storage locations; and

the second sub-frame metadata defines a second plurality of sub-frames within the sequence of full frames of video data, each of the second plurality of sub-frames having at least a second parameter that differs from that of the other of the second plurality of sub-frames.

2. The removable storage media of claim 1, wherein:

the first sub-frame metadata can be retrieved and used by the first video player system to tailor the sequence of full frames of video data for the first display; and

the second frame metadata can be retrieved and used by the second video player system to tailor the sequence of full frames of video data for the second display.

3. The removable storage media of claim 1, wherein the first parameter comprising a sub-frame center point within the sequence of full frames of video data.

4. The removable storage media of claim 1, wherein the first video player system comprising a television, and the second video player system comprising a computer.

5. The removable storage media of claim 1, wherein the first video display comprising a display of a hand-held device.

6. The removable storage media of claim 1, wherein the storage media comprises a video disk.

7. The removable storage media of claim 1, wherein the storage media comprises random access memory.

8. The removable storage media of claim 1, wherein the storage media comprises read only memory.

9. The removable storage media of claim 1, further comprising digital rights management data in at least a fourth of the plurality of storage locations, the digital rights management data relating to the sequence of full frames of video data.

10. The removable storage media of claim 1, further comprising digital rights management data in at least a fourth of the plurality of storage locations, the digital rights management data relating to the first sub-frame metadata.

11. The removable storage media of claim 1, further comprising:

audio data corresponding to the sequence of full frames of video data;

first sub-frame audio data corresponding to the first plurality of sub-frames; and

second sub-frame audio data corresponding to the second plurality of sub-frames.

12. The removable storage media of claim 1, wherein the first display characteristic comprising a first image resolution and the second display characteristic comprising a second image resolution.

13. The storage media of claim 1, wherein the first display characteristic comprising a first diagonal dimension, the second display characteristic comprising a second diagonal dimension, and the first diagonal dimension being substantially greater than the second diagonal dimension.

14. The removable media of claim 1, wherein the sequence of full frames of video data comprising an encoded sequence of full frames of video data.

15. Video player circuitry comprising:

media interface that receives a removable media, the removable media having stored thereon both full frame video and a plurality of sub-frame metadata;

interface circuitry communicatively coupled to a display having at least one display characteristic;

processing circuitry that selects first sub-frame metadata from the plurality of sub-frame metadata based upon the at least one display characteristic;

the processing circuitry generates tailored video from the full frame video using the first sub-frame metadata; and

the processing circuitry delivers the tailored video via the interface circuitry.

16. The video player circuitry of claim 15, wherein the processing circuitry performs post-processing pursuant to supplemental information as part of the generation of the tailored video.

17. The video player circuitry of claim 15, wherein the video player circuitry and the display are disposed in a single housing.

18. The video player circuitry of claim 15, wherein the video player circuitry is disposed in a first housing and the display is disposed in a second housing.

19. The video player circuitry of claim 15, further comprising decoder circuitry operable to decode the full frame video.

20. The video player circuitry of claim 15, wherein the full frame video has a first resolution and the tailored video has a second resolution that is less than the first. resolution.

21. The video player circuitry of claim 15, wherein the full frame video has a first aspect ratio and the tailored video has a second aspect ratio that differs from the first aspect ratio.

22. The video player circuitry of claim 15, wherein at least a portion of the processing circuitry comprises general purpose processing circuitry that performs underlying functionality pursuant to program code.

23. A method associated with a removable storage media, the method comprising:

storing first data representing a full screen video sequence;

storing second data representing first sub-frame metadata, the second data for use in producing first tailored video from the first data, the first sub-frame metadata defining both a first sub-frame within the full screen video sequence and a second sub-frame with the full screen video sequence, the first sub-frame having at least one characteristic that differs from that of the second sub-frame; and

storing third data representing second sub-frame metadata, the third data for use in producing second tailored video from the first data.

24. The method of claim 23, further comprising distributing the removable storage media.

25. The method of claim 23, wherein the first data is encoded.

26. The method of claim 23, further comprising coupling the removable media to a video player system.

27. The method of claim 23, further comprising storing fourth data relating to digital rights management.
