Abstract RU 2832719 C1

FIELD: physics.

SUBSTANCE: invention relates to video encoding. Result is achieved by the fact that the bit stream includes a current sequence parameter set (SPS) containing syntax elements that are applied to the video sequence, wherein the method of decoding said bit stream comprises steps of: obtaining a first syntax element used to determine the maximum number of temporary sublayers, which is allowed to be present in each coded layer video sequence (CLVS), which refers to the current SPS, wherein value of first syntax is in range from 0 to first value, wherein the first value is the value of a second syntax element used to determine the maximum number of temporary sublayers that can be present in a layer in each coded video sequence (CVS) referencing a video parameter set (VPS) when the second syntax element is referenced by an SPS, and the first value is a preset value when the second syntax element is not referenced by the SPS; bit stream is decoded based on the value of the first syntax.

EFFECT: high efficiency of video encoding.
