VIDEO PARAMETER SET SIGNALING

摘要

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.

1. 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.
