Abstract-- We consider the problem of how to enable the
streaming of live video content from a single server to a large
number of clients. One recently proposed approach relies on
the cooperation of the video clients in forming an application
layer multicast tree over which the video is propagated. Video
continuity is maintained as client departures disrupt the multicast
tree, using multiple description coded (MDC) streams multicast
over several application layer trees. While this maintains con-
tinuity, it can cause video quality fluctuation as clients depart
and trees are reconstructed around them. In this paper we
develop a scheme using the transmission of a single-description
coded video over an application layer multicast tree formed by
cooperative clients. Video continuity is maintained in spite of tree
disruption caused by departing clients using a combination of two
