PURPOSE:To prevent the receiving status of normal satellite broadcasting from being disturbed by controlling a system obtained by combining two satellite broadcasting receivers and a MUSE decoder so that a keyed AFC pulse based upon a MUSE signal received by one receiver is not outputted to the other receiver. CONSTITUTION:In the case of simultaneously recording normal satellite broadcasting signals in different channels as a sound and an image by a VTR 5 while looking/listening the normal satellite broadcasting signals by a TV 4, switches 54 to 57 are connected to the terminal (b) side. At the time of receiving a high vision broadcasting channel or the like in the status, a MUSE signal from an FM demodulator 42 is supplied to a MUSE decoder 7 and a keyed AFC pulse is outputted. However the pulse is interrupted by the switch 55 and is not supplied to a controller 53 in the VTR 5. Thereby horizontal stripes are not generated on the demodulation output screen of the VTR 5. |
