Processing of illegal motion vectors for intra block copy mode in video coding

Abstract:

An example method for coding video data includes determining, for a current block of a current picture of video data, the current block coded using an intra block copy (IBC) mode, whether a motion vector (MV) for identifying a prediction block for the current block is a legal MV. The example method further includes, responsive to determining that the MV is not a legal MV, reconstructing samples of the current block using an alternative processing method.
