Abstract
Encoding or decoding a video signal includes determining multiple candidate motion vectors for a current block, the candidate motion vectors including a first motion vector used to predict a collocated block within a first frame. A reference frame identifier associated with the first motion vector can be compared to a reference buffer index of a reference frame used to predict the current block of a second frame. On the condition that the reference frame identifier is the same as the reference buffer index, the first motion vector is advanced ahead of remaining ones of the multiple candidate motion vectors.
