ENCODER, DECODER AND CORRESPONDING SIGNALING METHODS AND SEMANTICS IN PARAMETER SETS Russian patent published in 2024 - IPC H04N19/31 H04N19/70 H04N19/136 H04N19/187 H04N19/184 

FIELD: physics.

SUBSTANCE: invention relates to video encoding means. Value of the first syntax element is obtained from the SPS, wherein the value of the first syntax element is used to indicate whether the syntax structure of parameters of the decoded image buffer, DPB, is present in the SPS. Value of the second syntax element is obtained from the SPS, at least when determining that the value of the first syntax element indicates that the syntax structure of the DPB parameters is present in the SPS. Value of the second syntax element is used to indicate the presence of the syntax element DPB in the syntax structure of the DPB parameters. Syntax DPB element is applied to the time sublayer, except for the highest time sublayer in the video sequence.

EFFECT: high efficiency of video encoding.
