Abstract

Cell loss is inevitable in ATM networks due to network congestion and appears to be a critical factor affecting the quality of video signal. For transmitting MPEG video over ATM networks, cell loss causes error propagation in both spatial and temporal domain, which in turn leads to severe degradation in image quality. In this paper, 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 cell loss compensation method called modified boundary matching algorithm is then proposed for transmitting MPEG video bit-stream in ATM networks. Simulation results demonstrate that the proposed method yields satisfactory results even when the cell loss rate is very high.
