1. A method for managing a decoded picture buffer (DPB) comprising:
responsive to a bitstream of a coded sequence of pictures, deriving a list of all reference pictures used in decoding of a portion of bitstream syntax essentially consisting of a single list of reference pictures including single number indicating a total number of all reference pictures;
decoding a picture in the coded sequence of pictures including predicting a portion of the picture from reference pictures in the list; and
parsing, from the bitstream syntax for entries in the list of reference pictures, an identification of a reference picture by a difference in a picture order count (POC) between a current picture and the identified reference picture, including:
parsing a magnitude of the difference;
determining if the magnitude of the difference is greater than zero;
when the magnitude is determined to be greater than zero, parsing a flag indicating a sign of the difference.
