Signaling scalability information in a parameter set
A system for decoding a video bitstream includes receiving a frame of the video that includes at least one slice and at least one tile and where each of the at least one slice and the at least one tile are not all aligned with one another.
1. A method for decoding a coded video sequence comprising:
(a) receiving a first syntax set that includes information applicable to a base layer of a coded video picture of said coded video sequence;
(b) receiving a second syntax set that includes information applicable to an enhancement layer of the coded video picture of said coded video sequence
wherein the first syntax set and the second syntax set include source dimension information for the base layer and the enhancement layer, respectively, the source dimension information indicating that the corresponding layer includes pictures having a mixture of frames in a two-dimensional format and a three-dimensional format;
(c) receiving a first source scan type information indicator identifying a source scan type of the base layer;
(d) receiving a second source scan type information indicator identifying a source scan type of the enhancement layer;
(e) decoding the base layer based on the first source scan type information indicator and the first syntax set; and
(f) decoding the enhancement layer based on the second source scan type information indicator and the second syntax set.
2. The method of claim 1 wherein said first and second source scan type information indicators indicate that a corresponding layer includes pictures having an interlaced scan type.
3. The method of claim 1 wherein said first and second source scan type information indicators indicate that a corresponding layer includes pictures having a progressive scan type.
4. The method of claim 1 wherein said first and second source scan type information indicators indicate that a corresponding layer includes pictures having an unknown scan type.
5. The method of claim 1 wherein said first or second source scan type information indicator indicates that a corresponding layer includes pictures having a mixture of interlaced and progressive scan type.
6. The method of claim 1 wherein said first or second source scan type information indicator indicates that a corresponding layer includes pictures having a scan type selected from the group including, (1) an interlaced scan type, (2) a progressive scan type, (3) an unknown scan type, and (4) a mixture of interlaced and progressive scan type.
