Abstract	The growth in mobile communication and Internet usage has lead to increase in demand for robust transmission of compressed video over error prone channels. The quality of decoded video in erroneous environment depends on efficient detection and concealment of errors. In this paper, improved error detection and concealment techniques using syntactic, semantic and statistical information in MPEG-4 are proposed. The proposed detection scheme can detect most types of transmission error and locate the exact position of the first error. The proposed concealment method can mask the impairments caused by the detected error significantly. The performance of the proposed detection and concealment techniques are evaluated with multiple video sequences at different bit error rates (BERs). Experimental results show the error detection ratio (EDR) of the detection scheme for different types of transmission error is more than 90%, close to 100% sometimes. And the improved detection technique combining with the improved concealment method can increase the video quality efficiently.
