METHODS OF REFERENCE PICTURE INDICATION FOR VIDEO CODING AND RELATED APPARATUSES
A method decodes one or more code words in a loop that is run N times by decoding an indication of whether a picture is a long-term picture or not and deriving a positive integer K[i]>0 for each long-term picture. An indicator value V[i] is derived for each long-term picture by subtracting the value of the positive integer K[i] from a picture indicator value P of the current picture. For each of the indicator values V[i], the indicator value V[i] is compared with values associated with pictures stored in the DPB. The method keeps the pictures stored in the DPB marked as short-term or long-term for which there is a match with one of the indicator values V[i] in the DPB as long-term pictures, and marks long-term pictures for which there is no match with any indicator value V[i] as unused for reference in the DPB.
