METHOD FOR SIGNALING OF SET OF OUTPUT LAYERS IN SCALABLE VIDEO STREAM Russian patent published in 2023 - IPC H04N19/31 H04N19/36 H04N19/187 

Abstract RU 2787850 C1

FIELD: video encoding/decoding.

SUBSTANCE: decoding of an encoded video bitstream, using at least one processor, includes obtainment of an encoded video sequence including multiple sets of output layers from the encoded video bitstream; obtainment of the first flag indicating, whether each set of output layers of multiple sets of output layers includes more than one layer; based on the first flag indicating that each set of output layers includes more than one layer, obtainment of the first syntax element indicating a mode of the set of output layers; selection of at least one layer from a number of layers included in multiple sets of output layers as at least one output layer based on at least one of the first flag and the first syntax element; and output of at least one output layer.

EFFECT: provision of a mechanism of signaling of a set of output layers for a scalable video stream.
