Title: INTRA PREDICTION FROM A PREDICTIVE BLOCK
Abstract:
A device for coding video data, the device comprising a memory configured to store video data and a video coder comprising one or more processors 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, wherein the first chroma reference block is in the picture; predict the first chroma block based on the first chroma reference block; locate a second chroma reference block using the vector, wherein the second chroma reference block is in the picture; and predict a second chroma block of the coding unit based on the second chroma reference block.
