Abstract
A method of decoding and encoding video data includes constructing a motion vector candidate list for the current block of video data based on the motion information from the neighboring blocks relative to the current block determined to include motion information, and adaptively ordering the constructed motion vector candidate list for the current block of video data based on at least one weight among a plurality of weights associated with motion information included in each neighboring block determined to include motion information.
