  • RF switching with remote controllers dedicated to other devices
    Patent number: 5815088
    Abstract: Apparatus and method for switching between two input sources to a television receiver and/or video recording device. Switching may be carried out with a conventional remote control otherwise dedicated to the video recorder or television receiver by holding down a control button thereof for at least a predetermined interval of time, for example two seconds. Five RF diode switches along with solid state logic components are employed to respond to the remotely developed switching signals for carrying out TV receiver and VCR source selections by the viewer. The pre-existing television or VCR operational status is not affected by the remote controllers where an ongoing channel selection simply is reinforced or a function of the remote controller is elected which has no undesired effect upon that ongoing operational status.
