%X An unsymmetrical cross-search algorithm(UDCS) was proposed based on motion vector distribution characteristics.Search steps of using small cross-search pattern to find small motion vectors in initial phase and unsymmetrical cross-search pattern to determine search large motion vectors in subsequent steps were brought forward.Finally,the architecture of the algorithm for implementation was introduced and performance was analyzed.
