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

摘要

Devices and methods for determining whether to initiate random access during decoding of video information. In one aspect, a device may include a memory configured to store video information that includes at least one recovery point supplemental enhancement information (SEI) message and a processor coupled to the memory. The processor is configured to determine whether the at least one recovery point SEI message comprises an indication to reset a picture order count (POC) semantic value. The processor is further configured to identify at least one of a first constraint regarding whether the recovery point SEI message is present in an access unit, a second constraint regarding an association of the recovery point SEI message with a picture, or a third constraint and determine whether to initiate the random access and decoding from the access unit based on at least one of the first constraint or the second constraint.
