ABSTRACT:
A network architecture for delivery of broadcast and interactive digital services over a hybrid fiber-coax distribution system. The network includes at least one remote/local hub that communicates with a plurality of video information providers (VIPs) and a plurality of headends/central offices. Each headend communicates with a plurality of settop terminals. The hub includes a backbone subnetwork which provides the physical medium for components within the hub to communicate with each other, and for entities located outside the hub, such as the VIPs and the headends, to communicate with, and through, the hub. The hub processes broadcast digital information services from a VIP and distributes the services directly to the plurality settop terminals. The network architecture permits two-way transparent data transport service between the VIPs and the video information users. Through frequency division multiplexing, the network architecture facilitates analog signal distribution so both analog and digital services can be distributed.
