- HEVC SEI USE OF SPECIFIC HEVC SEI MESSAGES FOR MULTI-LAYER VIDEO CODECS

摘要

Devices and methods are disclosed for improving the use of Supplemental Enhancement Information (SEI) messages in multi-layer codecs for decoding multi-layer bitstreams containing video information. In one aspect, a device is a memory configured to store video information associated with a multi-layer bitstream, wherein the stored video information may include a processor operatively coupled to the memory, have. The processor is configured to determine, based on the identifier in the SEI message, whether the SEI message belongs to a first SEI message category or a second SEI message category. The processor also determines whether an SEI message is applied to operating points or layers and, in response to the SEI message being of a first SEI message category and applied to operating points, To each of the operating points.
