Abstract
A video distribution network having an architecture that distributes video services over a greater serving area. The broadcast consolidation section receives broadband data from a plurality of information providers, preferably as compressed, digital signals using asynchronous transfer mode ATM transport. The broadcast consolidation section combines the ATM streams from different information providers and outputs a consolidated signal onto a transport ring. The broadcast ring supplies the consolidated broadcast signal to a plurality of video network hubs, each of which downloads the consolidated broadcast data, converts the consolidated broadcast data to motion picture experts group MPEG data on an RF carrier, and combines the RF signal with other RF signals before transmission by optical fiber to a plurality of local video access nodes. Each local video access node combines the RF broadcast data from the corresponding video network hub with downstream interactive multimedia television IMTV traffic supplied by an ATM backbone subnetwork. The combined RF signals are output from the local video access nodes to the access subnetwork servicing these subscribers. The architecture of the …
