REPRESENTATION FORMAT UPDATE IN MULTI-LAYER CODECS

摘要

An apparatus for encoding video information according to certain aspects includes a memory and a processor configured to: receive a video parameter set (VPS) including one or more representation format syntax structures, the VPS indicating a first representation format syntax structure associated with a first layer of the plurality of layers; receive a sequence parameter set (SPS) including (1) a reference to a second representation format syntax structure in the VPS or (2) a third representation format syntax structure not included in the VPS, each representation format syntax structure including a first flag indicative of whether to code color components of chroma format of a layer separately; and update a value of a first variable indicative of whether to code color components of chroma format of a layer separately without referring to a value of the first flag in the first representation format syntax structure.

1. An apparatus for encoding video information, comprising:
a memory for storing video information associated with a plurality of layers; and a processor operationally coupled to the memory and configured to:
receive a video parameter set (VPS) including one or more representation format syntax structures, the VPS indicating a first representation format syntax structure of the one or more representation format syntax structures associated with a first layer of the plurality of layers;receive a sequence parameter set (SPS) including (1) a reference to a second representation format syntax structure of the one or more representation format syntax structures in the VPS or (2) a third representation format syntax structure not included in the one or more representation format syntax structures in the VPS, each representation format syntax structure including a first flag indicative of whether to code color components of chroma format of a layer separately; andupdate a value of a first variable indicative of whether to code color components of chroma format of a layer separately without referring to a value of the first flag in the first representation format syntax structure, the first variable associated with the first layer.
