USE OF HEVC DECODED PICTURE HASH SEI MESSAGES FOR MULTI-LAYER CODECS.

摘要

In an example, a method of coding video data includes coding one or more non-video coding layer (VCL) network abstraction layer (NAL) units of a layer of a multi-layer bitstream, where the one or more non-VCL NAL units contain a decoded picture hash SEI message. The method also includes determining a set of layers of the multi-layer bitstream to which the decoded picture hash SEI message is applicable based on a layer identifier of the one or more non-VCL NAL units containing the decoded picture hash SEI message.
