Abstract
A VCR is connectable to a television receiver and a decoder of scrambled signal. The VCR provides connection paths for coupling a video signal and an audio signal between the television receiver and the decoder. The VCR receives a control signal from the decoder indicating whether the video signal received by the television receiver is scrambled. In a first stand-by mode of the VCR, if the video signal is not scrambled, only the video signal is routed to the decoder through the VCR. If a scrambled signal is received, then the audio signal is also routed to the decoder through the VCR.
