Abstract
A server in connection with a plurality of multimedia sources that has a plurality of clients. The server determines if at least one of the clients is requesting to receive at least one of the sources. The server then multicasts these requested sources to the requesting clients, respectively. If none of the clients is requesting a particular source, the server does not multicast that particular source. If all of the clients cease requesting a particular source that the server is currently multicasting, the server terminates the multicast of that particular source.
