Abstract
A communication system is provided for the distribution of switched video, along with telephony and control information, over fiber from a central office to a subscriber premises. The system can dynamically allocate video channels to subscribers using a pool of switched channel selector units located at the central office, thus permitting increased sharing of video distribution resources and controlling access to all channels. The system can provide a multiplicity of simultaneously available switched channels at each subscriber premises from a selection of over a hundred channels available at the central office. Subscribers are connected to the switched video service through a switched video distribution system rack. Switched channels will travel over single-mode fiber in AM/VSB format compatible with subscriber video equipment.
