Abstract:
A method of determining a reference picture set (RPS), which is a set of reference pictures used in predictive decoding of a current picture that is to be decoded, is provided. The method includes: obtaining a flag indicating whether the RPS is determined based on picture order count (POC) values of the current picture and a previous picture or whether the RPS is determined based on an index of a reference RPS, which is an identification value of the reference RPS that is one of pre-defined RPSs and is referred to in determining the RPS, and a delta RPS that is a difference value between a POC value of a reference picture included in the reference RPS and a POC value of a reference picture included in the RPS; and determining the RPS according to a value of the flag.

Claim (Index 7):
A non-transitory computer-readable storage medium storing a bitstream comprising:\n information of the number of reference picture sets, wherein the reference picture sets are included in a sequence parameter set and available to predict a current picture; and delta index information about a difference between an index of a current reference picture set of the current picture and an index of a reference reference picture set (reference RPS), wherein the index of the current reference picture set of the current picture indicates the current reference picture set of the current picture among reference picture sets; and a delta RPS which is a difference value between a picture order count (POC) value of a reference picture in the current reference picture set of the current picture and a picture order count (POC) value of a reference picture in the reference RPS of the current picture, wherein the delta index information and the delta RPS are generated to be used to determine the current reference picture set of the current picture when the index of the current reference picture set of the current picture is equal to the number of reference picture sets included in the sequence parameter set, wherein a value about the index of the reference reference picture set s smaller than a value about the index of the current reference picture set.
