FIELD: physics.
SUBSTANCE: invention relates to video encoding techniques. Result is achieved by receiving a bit sub-stream having a sequence parameter set (SPS) with a decoded picture buffer (DPB) syntax for an output layer set (OLS) with one single layer; setting the number of layers in the OLS to a value equal to one, based on the fact that the OLS has one single layer; obtaining a DPB syntax structure for OLS with one layer from the SPS, when the number of layers in the OLS is equal to one; and the single layer image is decoded using the DPB syntax to obtain a decoded image.
EFFECT: high efficiency of video encoding.
