Abstract :
Packet loss is a critical problem for video transmission on packet-switched networks. An error compensation method called the modified boundary matching algorithm is developed for recovering lost video due to packet loss at the video decoder. Simulation results demonstrate that the proposed method preserves good image quality even when the cell loss rate is very high
