Abstract

In this work we investigate the possibility of detecting errors in H.264/AVC encoded video streams. We propose a method for the detection of errors exploiting the set of entropy coded words as well as range and significance of the H.264/AVC information elements. We evaluate the performance of such syntax analysis based error detection technique for different bit error probabilities and compare it to the typical packet discard approach. Particular focus is given on low rate video sequences.
