Claim 5:
6. A method for transmitting video signals in an internet protocol network, the method comprising:
receiving a layered video data stream comprising a base layer and a set of enhancement layers;
identifying bandwidth-limited links of an internet protocol network between a video router and a plurality of video receivers in a peer-to-peer multicast;
forwarding the base layer to each of the plurality of video receivers in the multicast;
selectively forwarding one or more of the enhancement layers, but fewer than all of the set of enhancement layers received, to one or more of the plurality of video receivers through the bandwidth-limited links of the internet protocol network based upon throughput in the bandwidth-limited links;
wherein the layered video data stream is transmitted via a communications channel configured for an internet protocol, and wherein each layer of the layered video data stream comprises data packets; and
encoding a sequence number and priority identifier in each of the data packets, wherein the sequence number and the priority identifier for each data packet is based upon a layer to which the packet belongs.
