FIELD: data processing.
SUBSTANCE: invention relates to video decoding, particularly to determination of reference pictures set (RPS), which are used in predicting decoding of current picture (image). Disclosed is a method of determining RPS, which is a set of reference pictures used in predicting decoding of a current picture, involving: obtaining a flag indicating whether RPS is determined based on the value of the pictures order count (POC) of the current picture and the previous picture or whether RPS is determined based on the reference RPS index, which is the reference RPS identification value, which is one of the predetermined RPS sets and referred to when determining the RPS, and delta RPS, which is the difference value between the reference image POC value included in the reference RPS, and the reference picture POC value included in the RPS; and determining RPS in accordance with flag value.
EFFECT: high efficiency of video decoding.
