Abstract:
A video coder may determine a search region for coding a current block of video data using Intra Block Copy (Intra BC). In some examples, the video coder determines a central point for the search region, and determines the search region for the current block based on the central point and a defined size for the search region. The video coder stores reconstructed blocks of the video data from a current picture that includes the current block in a memory based on the determined search region. The video coder codes information from which to identify one of the reconstructed blocks within the search region, and codes the current block based on the identified one of the reconstructed blocks according to Intra BC.
