MPEG-2 can be used in many services such as video trunking, pay-per-view (PPV) and Near Video on Demand (NVOD). As MPEG-2 technology becomes commonplace in the cable headend, SONET technology plays a key role in backbone transport of digital content. With SONET, MPEG-2 can be transported using ATM or non-ATM modes. Both in the core and access network, SONET equipment will be standard. End-to-end connectivity is possible on SONET networks that support both modes. Thus SONET can be used as the transport technology of choice to carry MPEG-2 to interconnect service providers to users with exciting new services.
