    Abstract: Devices and methods for improving use of supplemental enhancement information (SEI) messages in multi-layer codecs for decoding multi-layer bitstreams containing video information are disclosed. In one aspect, a device may include a memory configured to store video information associated with the multi-layer bitstream, the stored video information comprising an SEI message and a processor operably coupled to the memory. The processor is configured to determine whether the SEI message belongs to a first SEI message category or a second SEI message category based on an identifier in the SEI message. The processor is further configured to determine whether the SEI message applies to the operation points or the layers and, in response to the SEI message being of the first SEI message category and applying to the operation points, associating each semantic of the SEI message with each operation point among the operation points.

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

    Abstract: Methods for defining decoder capability for decoding multi-layer bitstreams containing video information, in which the decoder is implemented based on multiple single-layer decoder cores, are disclosed. In one aspect, the method may include identifying at least one allocation of layers of the bitstream into at least one set of layers. The method may further include detecting whether each set of layers is capable of being exclusively assigned to one of the decoder cores for the decoding of the bitstream. The method may also include determining whether the decoder is capable of decoding the bitstream based at least in part on detecting whether each set of layers is capable of being exclusively assigned to one of the decoder cores.
