## Abstract

A method for encoding video data is provided that includes determining whether or not a parent coding unit of a coding unit of the video data was predicted in intra-prediction block copy (IntraBC) mode and, when it is determined that the parent coding unit was not predicted in IntraBC mode: computing activity of the coding unit, determining an IntraBC coding cost of the coding unit by computing the IntraBC coding cost of the coding unit using a two dimensional (2D) search when the activity of the coding unit is not than an activity threshold, and computing the IntraBC coding cost of the coding unit using a one dimensional (1D) search when the activity of the coding unit is less than the activity threshold, using the IntraBC coding cost to select an encoding mode from one of a plurality of encoding modes, encoding the coding unit using the selected encoding mode.

## Claims

### Claim 1

A system comprising:
a memory configured to store data for a picture; and
an encoder coupled to the memory and configured to:
determine that a parent coding unit of a child coding unit of the picture is not predicted in an intra-block copy mode; and
skip an intra-block copy search for the child coding unit in response to determining that the parent coding unit is not predicted in the intra-block copy mode.
