    The spacial and temporal character of motion vector were analysed and according to the spacial and temporal characteristic of motion vector, the different proposed search schemes were adopted for motion estimation; The experi-mental results shows the proposed algorithm reduce the prediction error and has a significant computational speedup compared with other algorithms, but offers a similar, even better performance.
