Abstract
A cable television/video distribution and selection system for distributing video signals throughout a home or building over in-wall electrical wiring. A remote device is connected to a display monitor or television set and also to the electrical wiring through an electrical outlet. The remote device is comprised of a first video signal selector device which is used by a user to generate a selection signal which corresponds to the cable television channel which the user has selected. The remote device also includes a transmitter/receiver for sending the selection signal-over the electrical wiring to a tuner and then receiving the video signal (television station) from the tuner. The transmitter/receiver matches the characteristic impedance of the electrical wiring and is tuned to a predetermined frequency band. The distribution device is connected to the electrical wiring and also to a video signal source, such as a cable television cable entering the building. The distribution device contains a second transmitter/receiver which is tuned to the same frequency band as the remote device and is similarly matched to the characteristic impedance of the electrical wiring. The distribution device also contains a tuner for tuning the cable television channel corresponding to the selector signal it receives from the remote device. After the requested channel is tuned by the tuner, the video signal is sent back to the remote device for viewing on the display monitor.
