Abstract
Techniques and systems are provided for encoding and decoding video data. For example, a method of encoding video data including a plurality of pictures is described. The method includes performing intra-picture prediction on a block of one of the pictures to generate a prediction unit. Performing the intra-picture prediction includes selecting a reference block for intra-block copy prediction of a coding tree unit (CTU). The reference block is selected from a plurality of encoded blocks, and blocks within the CTU encoded with bi-prediction are excluded from selection as the reference block. Performing the intra-picture prediction further includes performing intra-block copy prediction with the selected reference block to generate the prediction unit. The method also includes generating syntax elements encoding the prediction unit based on the performed intra-picture prediction.
