Abstract
A scalable video decoder provides a method for decoding a video sequence comprising: decoding a plurality of frames of said video sequence where at least two of said frames belonging to a different one of a plurality of layers; said video sequence includes a video parameter set (VPS) syntax used for said decoding regions of an encoded video; said VPS syntax includes a VPS extension set syntax including attributes regarding representation format characteristics (e.g. color characteristics); said VPS extension set syntax including a number of representation format characteristic syntax structures and an index referencing a representation format structure for each layer; each of said number of said representation format characteristic syntax structures indicates a different set of said attributes.
Claims10
A method for decoding a video sequence comprising:
- (a) receiving said video sequence,
- (b) identifying a video parameter set syntax included in said video sequence;
- (c) identifying a video parameter set extension syntax included in said video parameter set syntax;
- (d) identifying, from said video parameter set extension syntax, representation formats, a number of said representation formats, indexes referencing said representation formats for each of a plurality of layers and a present flag indicating whether or not said indexes are present;
- and
- (e) decoding a plurality of frames of said video sequence by using said representation formats and said indexes.
4-5. (canceled)
A device for decoding a video sequence comprising:
- circuitry to:
- receive said video sequence;
- identify a video parameter set syntax included in said video sequence;
- identify a video parameter set extension syntax included in said video parameter set syntax;
- identify, from said video parameter set extension syntax, representation formats, a number of said representation formats, indexes referencing said representation formats for each of a plurality of layers and a present flag indicating whether or not said indexes are present;
- and
- decode a plurality of frames of said video sequence by using said representation formats and said indexes.
A device for encoding a video sequence comprising:
- circuitry to:
- encode representation formats, a number of said representation formats, indexes referencing said representation formats for each of a plurality of layers and a present flag indicating whether or not said indexes are present;
- encode a video parameter set extension syntax including said representation formats, said number of said representation formats, said indexes and said present flag;
- encode a video parameter set syntax including said video parameter set extension syntax;
- and
- send a video sequence including said video parameter set syntax.
