SYSTEMS AND METHODS FOR CONSTRAINING REPRESENTATION FORMAT PARAMETERS FOR A PARAMETER SET

摘要

Techniques and systems are provided for encoding video data. For example, a method of encoding video data includes generating an encoded video bitstream comprising multiple layers. The encoded video bitstream includes one or more sequence parameter sets and a video parameter set. The method further includes generating, according to a constraint, one or more representation format parameters for a sequence parameter set assigned to a base layer of the encoded video bitstream. The constraint limits values of the one or more representation format parameters in the sequence parameter set to be less than or equal to values of corresponding representation format parameters that are assigned to the base layer in the video parameter set.
