Abstract: The present invention relates to an automated optoelectronic switched distribution system. A head end switching control center is provided. Optical fibers are connected to the head end switching control center. Subsidiary switching control centers (SCC) are connected to the optical fibers. Coaxial feeders are connected to the subsidiary switching control centers. Subscribers are connected to each feeder. Each feeder can carry numerous channels and each subscriber is connected to at least two allocated channels from the feeder. The subsidiary switching control center has remote switching and processing converters for receiving signals from the optical fibers and transmitting signals to a channel allocated to an individual subscriber. Each subsidiary switching control center has a remote switching and processing converter-transmit to receive signals from a subscriber's allocated transmit channel and to direct that signal to an output channel.

Abstract: A two-way cable distribution system for offices and office/apartment complexes wherein a single cable is used to interconnect tenants or owners with video/audio, facsimile, security and data services; with each user being allocated dual TV channels for the simultaneous transmission and reception of programs--all with complete privacy. User's multi-channel remote switching and processing converters (RSPC) are mounted in the switching control center where they also double as precision frequency controlled channel processors and eliminate problems of switching video crosstalk that occurs with IF or baseband switching. Spectrum capacity on each riser exceeds 800 MHz and enables more than 60 users per riser, each to be assigned 12 MHz bandwidth, without the need for line extenders amplifiers. Trunking of signals between buildings within a complex is not required because of riser transmissions that assign user drops in descending frequency along the length of the cable.

Abstract: A two-way cable television broadcasting system wherein a single coaxial cable is used to deliver TV and FM programs to many subscribers with each subscriber having a specific allocated band of frequencies for reception of any desired television or FM program and where each subscriber can independently select the program desired to be seen and/or heard which will be delivered to the subscriber over an allocated band of frequencies. The subscriber drops from said coaxial cable are so arranged that they descend in frequency along the length of the feeder cable. Automatic switching of any incoming program to any drop is achieved by means of converting all incoming channels to a common I.F. frequency at an amplifier or control station and then deconverting said frequency to the desired outgoing band of frequencies.
