The encapsulation of MPEG (Motion Pictures Experts Group) within a label switching protocol such as MPLS (Multiple Protocol Label Switching) is used to implement a multimedia communications network. The network advantageously improves the delivery of customized services to network subscribers. Encapsulating MPEG within MPLS simplifies network deployment by converging the previously distinct environments of data communications and broadcast television service over cable TV networks. In addition, the encapsulation of MPEG within MPLS allows merging MPEG program content streams with IP streams at the MPLS multiplexing level. This allows for applications such as merging MPEG video programs with IP advertising. Furthermore, the MPEG Digital Storage Medium Command and Control (DSM-CC) protocol may be used for label distribution for the label switching network.
