Classification: CPC H | IPC H

Claim 14:
15. A method comprising:
computing an inter-prediction coding cost for a coding unit (CU);
computing an intra-prediction coding cost for the CU;
determining whether a minimum of the inter-prediction coding cost and the intra-prediction coding cost is greater than a cost threshold;
when a parent CU was not predicted in an intra block copy (IntraBC) mode:
computing activity of the CU;
determining whether the activity of the CU is less than an activity threshold;
when the activity is not less than the activity threshold:
computing an IntraBC coding cost of the CU using a two dimensional (2D) search; and
selecting a mode for encoding the CU based on the inter-prediction coding cost, the intra-prediction coding cost, and the IntraBC coding cost computed with the 2D search.
