This contribution presents three aspects to extend the use of intra block copy (IBC). In aspect #1, combined IBC and intra prediction (IBC-CIIP) is proposed, in which the prediction of a CU is obtained by blending two predictions generated by IBC and intra prediction. In aspect #2, IBC with geometry partitioning (IBC-GPM) is proposed, in which a CU is divided into two sub-partitions geometrically, predicted by IBC and intra prediction individually. In aspect #3, IBC with local illumination compensation (IBC-LIC) is proposed. On top of ECM-6.0, simulation results of the proposed method are reported as below:
