Many overlay multicast schemes have been proposed recently at the application level to support VoD service over the Internet. However, these schemes are not designed to handle the characteristics of the noisy wireless links. In this paper we propose an overlay multicast scheme called Quick Patch which arranges additional patch streams to clients under poor link conditions to improve their clients' viewing quality. We demonstrate through extensive simulation experiments that Quick Patch is not only scalable, but can sustain the required viewing quality under different network conditions including fluctuating error conditions
