Abstract:
A method for a video encoder or decoder using an Intra Block Copy (IntraBC) mode is disclosed. If IntraBC mode is enabled and no loop filter is used for a current picture, a currently decoded reference picture for the current picture is marked as a long-term reference picture before and during decoding of the current picture. The currently decoded reference picture is assigned in reference picture list construction for IntraBC reference of the current picture and buffer fullness for the DPB is calculated before starting decoding the current picture by taking into account of only one reference picture buffer. According to another method, if the maximum DPB size is 1, a variable or a syntax element is set to a target value to impose restriction to use only one picture storage buffer in the DPB to store reference picture for encoding or decoding of a current picture.

Claim (Index 13):
The method of  claim 12 , wherein the total number of reference pictures is calculated as a sum of a first total number of short-term RPS (reference picture set) that have POC (picture order count) values less than the POC value of the current picture, a second total number of short-term RPS that have the POC values greater than the POC value of the current picture, a third total number of long-term RPS, and a version value associated with the information regarding whether two versions of the current decoded picture are used, and wherein the version value is 1 if two versions of the current decoded picture are used and the version value is 0 if one version of the current decoded picture is used.
