Efficient error handling for video and still picture standards

This paper describes new methods for errors handling at the decoder side, when channel noise affects the transmission of the compressed stream. The proposed error detection techniques are applied to MPEG-4 standard video, but can be also used for general video and still picture standards in which Inverse Quantization clipping or resynchronization markers are present as MPEG-2, H263, H26L, JPEG and JPEG2000. The Improved error concealment techniques presented can be extended to all the standards in which Reverse Variable Length Coding is present 1 .
