Abstract

A system for encoding and/or decoding video that includes the use of super blocks. The use of super blocks permits a reduction in the bit-rate of the video bit stream.

Claims

1. A method for decoding video comprising:

(a) receiving a super block flag indicating a super block consisting of a plurality of smaller blocks of pixels having shared decoding information with said super block;

(b) receiving a coded block pattern flag indicating whether said super block has a residual;

(c) decoding said super block based upon said super block flag and said coded block pattern flag.

2. The method of claim 1 wherein said super block is 32×

32 pixels.

3. The method of claim 2 wherein said of said smaller blocks are 16×

16 pixels.

4. The method of claim 1 wherein said super block is 64×

64 pixels.

5. The method of claim 1 wherein said shared decoding information includes at least one of (a) block type;

(b) transform type; and

(c) motion vector.

6. The method of claim 5 wherein said decoding information includes at least two of (a), (b), and (c).

7. The method of claim 6 wherein said decoding information includes at least three of (a), (b), and (c).

8. The method of claim 1 wherein said super block has a block order and said shared decoding information is included together with the first of said smaller blocks of said block order.

9. The method of claim 1 wherein said shared decoding information is not included in other ones of said smaller blocks of said super block.

10. The method of claim 1 wherein said shared decoding information includes at least one of (a) macro block skip;

(b) transform size; and

(c) delta quantization.

11. The method of claim 10 wherein said decoding information includes at least two of (a), (b), and (c).

12. The method of claim 11 wherein said decoding information includes at least three of (a), (b), and (c).

13. The method of claim 1 wherein said shared decoding information includes (a) block type;

(b) transform type;

(c) motion vector;

(d) macro block skip;

(e) transform size; and

(f) delta quantization.

14. A method of decoding video comprising:

(a) receiving a super block consisting of a plurality of smaller blocks of pixels having shared decoding information with said super block in a bit stream of encoded said video;

(b) extracting said shared decoding information from one of said smaller blocks of pixels;

(c) applying said shared decoding information to another one of said smaller blocks of pixels of said super block;

(d) decoding said one of said smaller blocks based upon said shared decoding information;

(e) decoding said another one of said smaller blocks based upon said shared decoding information.

15. The method of claim 14 further receiving a super block flag indicating said super block.

18. The method of claim 14 wherein said super block is 32×

32 pixels.

19. The method of claim 18 wherein said of said smaller blocks are 16×

16 pixels.

20. The method of claim 14 wherein said super block is 64×

64 pixels.

21. The method of claim 14 wherein said shared decoding information includes at least one of (a) block type;

(b) transform type; and

(c) motion vector.

22. The method of claim 21 wherein said decoding information includes at least two of (a), (b), and (c).

23. The method of claim 22 wherein said decoding information includes at least three of (a), (b), and (c).

24. The method of claim 14 wherein said super block has a block order and said shared decoding information is included together with the first of said smaller blocks of said block order.

25. The method of claim 14 wherein said shared decoding information is not included in other ones of said smaller blocks of said super block.

26. The method of claim 14 wherein said shared decoding information includes at least one of (a) macro block skip;

(b) transform size; and

(c) delta quantization.

27. The method of claim 26 wherein said decoding information includes at least two of (a), (b), and (c).

28. The method of claim 27 wherein said decoding information includes at least three of (a), (b), and (c).

29. The method of claim 14 wherein said shared decoding information includes (a) block type;

(b) transform type;

(c) motion vector;

(d) macro block skip;

(e) transform size; and

(f) delta quantization.

16. The method of claim 16 further comprising receiving a coded block pattern flag indicating whether said super block has a residual.

17. The method of claim 16 further comprising decoding said super block based upon said super block flag and said coded block pattern flag.
