Claim One:
1. A decoder for decoding a video encoded in a data stream, comprising: a desymbolizer configured to debinarize binarizations of horizontal and vertical components of motion vector differences, wherein the video is predictively coded by motion compensated prediction using motion vectors, the horizontal and vertical components of the motion vector differences representing prediction error with respect to the motion vectors, and each of the binarizations of the horizontal and vertical components including a prefix bin string having two bins based on a cutoff value equal to two, and a suffix bin string having an Exp-Golomb code of order one, wherein each of the two bins of the prefix bin string is individually coded as a fixed length binary code and represents a flag associated with an absolute value of a motion vector difference; and a reconstructor configured to reconstruct the video based on the debinarized values of the horizontal and vertical components of the motion vector differences.
