| Abstract: | Authors analyzes briefly the video coding principle on MPEG 4 and H.263 standard. Based on the coding experiment of image sequences, compares and analyzes coding performance, such as the output bitrate,peak signal and noise ratio and subjective image quality between MPEG 4 and H.263 The comparison results are given. |
