We present a construction to transmit high quality video streams, such as MPEG-video in realtime over lossy channels. To protect our messages against losses in the network during transit we use a new Forward Error Correction (FEC) scheme called ERT \cite{Gue96}. Unfortunately a lot of losses are not caused by the network itself but by buffer overflows in the receivermachine when the receiver is not as fast as the sender. In this case we do not use a single machine as the receiver but a cluster of workstations.
