Abstract
A system for multicast streaming of programs over a packet network includes a node having a processor that conditions a video bitstream such that packets containing an I-frame are located near program specific information (PSI) packets, the processor marking a random join point (RJP) in the video bitstream immediately preceding the I-frame and PSI packets, the node outputting the conditioned and marked video bitstream across the packet network. An edge device of the network includes a buffer that caches packets of the conditioned and marked video bitstream video starting at the RJP, and sends the cached packets to a client receiver.
