<p>A combination system having a DVDP (120) and a VCR (110) has a unit for inputting a selection command (111) for setting an operation mode, a unit for outputting the operation mode (210), a D/A converter (160) disposed in the DVDP, a blocking circuit (170) disposed in an output path of video data output from the DVDP, and a control unit (115) for controlling the above elements. The control unit (115) controls the output unit to output an indication of whether the video signal reproduced by the DVDP (120) is a wide screen signal when a DVD mode for operating the DVDP is selected. The control unit (115) stops the operation of the D/A converter (160) and activates the blocking circuit (170) when an operation mode other than the DVD mode is selected. When there is a need to release a view restriction function, the control unit (115) sends a control signal to a channel decoder (300) through a canal control signal output unit (310). Therefore, a control signal appropriat</p> |
