INTRA MOTION COMPENSATION EXTENSIONS

摘要

A video coder comprising one or more processors determines that a current block of the video data is encoded using an intra motion compensation (IMC) mode, wherein the current block is in a frame of video; determines an offset vector for a first color component of the current block of the video data; locates, in the frame of video, a reference block of the first color component using the offset vector; modifies the offset vector to generate a modified offset vector in response to the offset vector pointing to a sub-pixel position for a second color component of the current block of video data; locates, in the frame of video, a reference block for the second color component using the modified offset vector; and codes the current block based on the reference block for the first color component and the reference block for the second color component.
