Then the motion vector predictor is used only for Luma motion vector prediction while Chroma motion vector is derived from the corresponding Luma vector. Generally speaking Luma motion vector is calculated by adding the motion vector predictor MVP to the motion vector differential MVD for every active prediction direction. Notice that MVD is extracted from the stream (see "mvd_l0"/"mvd_l1" syntax elements in the standard). In MPEG-4 AVC/H.264 there are direct and skip modes where motion vectors are not signaled and are derived from spatial neighboring blocks and a temporal co-located block.
