ACCESS BLOCKS SEPARATOR SIGNALING METHOD Russian patent published in 2022 - IPC H04N19/70 H04N19/174 H04N19/169 

FIELD: data processing.

SUBSTANCE: invention relates to the field of data processing. Proposed method and apparatus includes computer program code configured to ensure that the processor or processors perform the following: receiving video data; defining an access block delimiter syntax in at least one network abstraction layer (NAL) block in said video data; determining whether the access unit separator syntax indicates a slice type value for said NAL unit; determining whether the access unit delimiter syntax in said NAL unit indicates a video coding level (VCL) value and/or an access unit sequence number value for the NAL unit; and signaling access unit boundary values ​​for the NAL unit according to whether the access unit delimiter syntax indicates at least one of a slice type value, a VCL value, and an access unit sequence number value.

EFFECT: improving the display of random access block information and improving the reliability of access block boundary detection.
