ABSTRACT:
A VCR includes circuitry for controlling a cable converter unit, circuitry for detecting the presence of a television signal, and control code transmission means for remotely controlling a cable converter unit. Advantageously, because the VCR is coupled to the output of the cable converter unit, the VCR can monitor the television signals received from the cable converter unit to ensure that commands sent to the cable converter unit from the VCR are executed. In one embodiment, infrared (IR) transmission of commands from the VCR to the cable converter unit is employed.
