摘要
PURPOSE: A distributed motion estimation method in a video encoder is provided to accurately predict movement while keeping complexity of a video encoder lower to increase accuracy of channel modeling, thereby increasing compressing efficiency. CONSTITUTION: A distributed motion estimation method in a video encoder comprises the following steps. A total prediction step number for phased motion prediction about current frame data is determined using previous frame data. A motion vector is generated by performing motion prediction about current frame data as many as real prediction steps whose number is lower than total prediction step number. The total prediction step number, real prediction step number and motion vector are transmitted to a decoder.
