FIELD: video data encoding and decoding.
SUBSTANCE: increase in the efficiency of video coding is achieved by receiving an encoded video stream including a set of video parameters and video data divided into multiple layers, obtaining, based on the set of video parameters, syntax elements containing signalling overhead for transmitting a set of video parameters with a large number of sets of output layers and/or layers in each set of output layers, and decoding, based on information obtained from the set of video parameters, a portion of the video data of the encoded video stream that corresponds to the set of output layers.
EFFECT: increase in the efficiency of video coding.
