摘要： PURPOSE:To set the reproduction system conformed to a tape by providing the reproduction system changeover controller to a conventional system configuration. CONSTITUTION:When a reproduction command is sent from a reproduction system changeover controller 1 to a reproduction device 3, the reproduction device 3 sets a VTR 9 to the reproduction state. The reproduction device 3 outputs a video signal to the NTSC changeover switch SW 4 and outputs a control signal recorded on the tape to the reproduction system changeover controller 1. The reproduction system changeover controller 1 discriminates whether or not the signal of the NTSC system is reproduced based on the frequency of the signal and outputs a video processing switching signal to the NTSC changeover switch SW4. When the NTSC SW is turned on, the video signal is fed to a video output form changeover device 7 and when the NTSC changeover switch is turned off, and the signal is sent to a PAL/SECAM/ MESCAM video processing unit 6 via a PAL/SECAM/MESECAM recording discrimination device 5 and in the case of the reproduction of the NTSC signal, a reproduction system control signal is outputted to the video output form changeover device 7 to control the reproduction system.
