Abstract：
 A motion estimating method of H.264 / AVC coder divides integer motion estimation to be rough layer and fine layer being estimated separately in sequence then inputting parallel interpolation of half pixel and fine layer motion estimation into reference frame data and integer pixel data of rough layer motion vector separately and carrying out half pixel motion estimation as well as quarter pixel motion estimation for calculating out final minimum residual error and its corresponding final motion vector by utilizing motion vector corresponding to minimum residual error under optimum prediction mode obtained from rough layer motion estimation.
