AN ENCODER, A DECODER AND CORRESPONDING METHODS USING IBC SEARCH RANGE OPTIMIZATION FOR ABITRARY CTU SIZE

摘要

The present disclosure provides a method of video coding implemented by a decoding device or an encoding device for optimum usage of a hardware reference memory buffer, wherein a group of reference coding tree units (CTUs) for Intra Block Copy (IBC) mode prediction of a current block of a current CTU is determined based on a size of the current CTU, and wherein the reference samples of the current block are obtained from the group of reference CTUs.
