H.263-video-decode-based error detection and concealment

This paper presents an error correction method applied in H.263 video coding, which is H.263 video decode based error detection and concealment algorithm. This algorithm can be applied in video communication of Public Switched Telephone Network (PSTN), Internet or mobile channel. It has been found that this error correction method can greatly improve the quality of images transmitted on channel with noise interference and will not decrease compression ratio.
