Improved compatibility and interoperability in multi-layer video coding

摘要

The present disclosure provides devices and methods for processing video data. The method can include extracting an output operation point from the received video data. If the output operation point corresponds to one of the entire bitstream and the temporal subset of the entire bitstream with only the base layer as output, the method includes performing a first bitstream conformance test. May be included. If the output operation point corresponds to one of the layer set specified by the base video parameter set (VPS) of the active VPS and the temporal subset of the layer set, where only the base layer should be output May include performing a second bitstream conformance test. If the output operation point corresponds to one of the output layer set (OLS) specified by the VPS extension of the active VPS and the temporal subset of OLS, the method performs a third bitstream conformance test Steps may be included.
