Abstract

In one example an apparatus for coding video data comprises a video coder configured to for a parallel motion estimation (PME) region comprising a plurality of blocks of video data within the PME region identify a common set of spatial candidate blocks outside of and adjacent to the PME region each of the common set of spatial candidate blocks at a respective predefined location relative to the PME region and for each of the blocks within the PME region for which motion information prediction is performed generate a respective motion information candidate list wherein for at least some of the blocks within the PME region for which motion information prediction is performed generating the motion information candidate list comprises evaluating motion information of at least one of the common set of spatial candidate blocks for inclusion in the motion information candidate list for the block.
