Abstract

In one embodiment, a method that includes receiving plural representations of a video signal, the video signal comprising plural sequenced pictures corresponding to at least a portion of a video program, wherein two or more of the plural representations of the video signal (PROTVS) includes a respective sequence of latticed pictures and one or more of the other PROTVS includes a respective sequence of non-latticed pictures; and providing in plural successive non-overlapping segments distribution interval (SDIs) compressed versions of the PROTVS in a single video stream, wherein each SDI consists of plural non-overlapping, consecutive segments, each of the plural non-overlapping consecutive segments originating from a respective one of the collective PROTVS.

Claims

1. A method, comprising:

receiving plural representations of a video signal, the video signal comprising plural sequenced pictures corresponding to at least a portion of a video program, wherein two or more of the plural representations of the video signal (PROTVS) includes a respective sequence of latticed pictures and one or more of the other PROTVS includes a respective sequence of non-latticed pictures; and

providing in plural successive non-overlapping segments distribution interval (SDIs) compressed versions of the PROTVS in a single video stream, wherein each SDI consists of plural non-overlapping, consecutive segments, each of the plural non-overlapping consecutive segments originating from a respective one of the collective PROTVS.

2. The method of claim 1, wherein the one or more of the other PROTVS include a portion of the plural sequenced pictures of the video signal designated as non-reference pictures in compressed form.

3. The method of claim 1, wherein the non-latticed pictures of the one or more of the other PROTVS possess a picture resolution equal to the corresponding pictures of the video signal.

4. The method of claim 1, wherein the two or more of the PROTVS each include latticed video representations of a respective corresponding portion of the plural sequenced pictures of the video signal.

5. The method of claim 1, wherein the latticed pictures of the two or more of the PROTVS possess a picture resolution less than the corresponding pictures of the video signal.

6. The method of claim 1, wherein providing further comprises compressing the pictures of the PROTVS, segmenting the compressed pictures, and ordering the segments within each SDI and among the plural SDIs.

7. The method of claim 1, wherein within at least one of the plural SDIs, the compressed non-latticed picture corresponding to at least one of the plural segments is dependent on one or more compressed reference latticed pictures corresponding to at least one of the plural segments.

8. A method, comprising:

receiving a single video stream, wherein the video stream includes plural processed representations of a single video signal, wherein two or more of the plural processed representations of the video signal (PPROTVS) includes a respective sequence of processed latticed pictures and one or more of the other PPROTVS includes a respective sequence of processed non-latticed pictures, wherein each of the PPROTVS is received in plural successive non-overlapping segments distribution interval (SDIs), wherein each SDI consists of plural non-overlapping, consecutive segments, each of the plural non-overlapping consecutive segments originating from a respective one of the PPROTVS; and

providing reconstructing versions of the received PPROTVS for subsequent display.

9. The method of claim 8, wherein the one or more of the other PPROTVS include compressed non-reference pictures.

10. The method of claim 8, wherein the processed non-latticed pictures of the one or more of the other PPROTVS possess a picture resolution in reconstructed form equal to the corresponding pictures of the video signal.

11. The method of claim 8, wherein the two or more of the PPROTVS each include processed latticed video representations of a respective corresponding portion of the plural sequenced pictures of the video signal.

12. The method of claim 8, wherein the processed latticed pictures of the two or more of the PPROTVS possess a picture resolution in reconstructed form less than the corresponding pictures of the video signal.

13. The method of claim 8, wherein providing further comprises decompressing the processed pictures of the PPROTVS, de-latticing the decompressed pictures where appropriate, and outputting the de-latticed pictures to a display device.

14. The method of claim 8, wherein within at least one of the plural SDIs, the processed non-latticed pictures corresponding to at least one of the plural segments is dependent on one or more compressed reference latticed pictures corresponding to at least one of the plural segments.

15. A system, comprising:

a memory having executable instructions; and

one or more processors configured to execute the instructions, the instructions causing the one or more processors to;

receive plural representations of a video signal, the video signal comprising plural sequenced pictures corresponding to at least a portion of a video program, wherein two or more of the plural representations of the video signal (PROTVS) includes a respective sequence of latticed pictures and one or more of the other PROTVS includes a respective sequence of non-latticed pictures; and

provide in plural successive non-overlapping segments distribution interval (SDIs) compressed versions of the PROTVS in a video stream, wherein each SDI consists of plural non-overlapping, consecutive segments, each of the plural non-overlapping consecutive segments originating from a respective one of the PROTVS.

16. The system of claim 15, wherein the one or more of the other PROTVS include a portion of the plural sequenced pictures of the video signal designated as non-reference pictures in compressed form.

17. The system of claim 15, wherein the non-latticed pictures of the one or more of the other PROTVS possess a picture resolution equal to the corresponding pictures of the video signal.

18. The system of claim 15, wherein the two or more of the PROTVS each include latticed video representations of a respective corresponding portion of the plural sequenced pictures of the video signal.

19. The system of claim 15, wherein the latticed pictures of the two or more of the PROTVS possess a picture resolution less than the corresponding pictures of the video signal.

20. The system of claim 15, wherein the one or more processors are further configured to compress the pictures of the PROTVS, segment the compressed pictures, and order the segments within each SDI and among the plural SDIs.
