Abstract
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.
Claims9
A method for decoding a coded video sequence comprising:
- receiving a video syntax set that includes information applicable to said coded video sequence, where said coded video sequence includes a plurality of layers of coded video frames;
- and
- decoding said coded video sequence with said video syntax set;
- wherein said video syntax set includes a dependency flag indicating one or more direct dependencies between said plurality of layers of said coded video sequence and said video syntax set further includes a syntax element number and at least one pair of indexes (i,j) when said direct dependency specifies said layer indexed by said second index value is a direct reference layer for said layer indexed by said first index value, and wherein said syntax element number specifies the number of layers the layer indexed by said first index value directly depends on, wherein i is said first index value and j is said second index value;
- and
- wherein said direct dependency specifies whether a particular layer indexed by a second index value is a direct reference layer for another layer indexed by a first index value.

An electronic device, comprising:
- a processor;
- and
- a non-transitory computer readable storage medium storing program for execution by the processor, the program including instructions to:
- receive a video syntax set that includes information applicable to said coded video sequence, where said coded video sequence includes a plurality of layers of coded video frames;
- and
- decode said coded video sequence with said video syntax set;
- wherein said video syntax set includes a dependency flag indicating one or more direct dependencies between said plurality of layers of said coded video sequence;
- wherein said direct dependency specifies whether a particular layer indexed by a second index value is a direct reference layer for another layer indexed by a first index value;
- wherein said video syntax set further includes a syntax element number and at least one pair of indexes (i,j) when said direct dependency specifies said layer indexed by said second index value is a direct reference layer for said layer indexed by said first index value, wherein said syntax element number specifies the number of layers the layer indexed by said first index value directly depends on, wherein i is said first index value and j is said second index value.
