Abstract:
A device for coding video data is configured to: determine a coding unit of a picture of the video data is coded using an intra block copy mode; determine a vector for a first chroma block of the coding unit; locate a first chroma reference block using the vector, the first chroma reference block being in the picture; predict the first chroma block based on the first chroma reference block; locate a second chroma reference block using the vector, the second chroma reference block being in the picture; and predict a second chroma block of the coding unit based on the second chroma reference block.
