Abstract: The invention provides a system and method for processing one or more audio/video sources for connection to a video monitor and speaker, utilizing a single coaxial cable between each remotely located audio/video source and a processing means. It provides a simultaneous or sequential display of one or more remotely located video sources and annunciation of one or more remotely located audio sources. The processing means and the audio/video sources include a splitter and combiner to separate and combine, respectively, an audio/video modulated carrier from DC power. The processing means and the video source may contain a switch for selecting power from the coaxial cable or from a local power source. By requiring only a single coaxial cable between each video source and the processing means, cable installation is greatly simplified.
