Loss recovery techniques for transmission of MPEG video over ATM networks

Cell loss is a critical problem for transmission of video over ATM networks. We first introduce a structural method for packing MPEG video bit-stream into ATM cells. With this method, the impact of cell loss can be limited to the lost cells only. A compensation method called the modified boundary matching algorithm is then proposed for recovery of the lost video information. Simulation results demonstrate that the proposed method yields satisfactory results even when the cell loss rate is very high.
