Paper Abstract

Compressed video bitstreams are very sensitive to transmission errors. If we lose packets or receive them with errors during transmission, a video decoder normally applies error concealment techniques to repair the damaged frame. The effectiveness of these error concealment schemes relies on the performance of the error detection algorithm. In this paper, we present a new error detection scheme based on a fragile watermarking algorithm to support error concealment. We verified that the proposed algorithm generates good performances in peak signal-to-noise ratio and objective visual quality test through the computer simulation by H.324M mobile simulation set.
