Abstract

PURPOSE:To record and process a video signal synchronously with a color frame by outputting a trigger setting a recording timing of a video signal fed to a video recorder externally synchronously with the color frame of the video signal. CONSTITUTION:A trigger 31 outputted from an external device 3 utilizing an edit device or the like is fed to a controller 12 of a video recorder 1 via an input port 121. Then a main body 11 extracts reference color frame information inputted always from a picture processing unit being a main body to the video recorder 1 based on relation between a synchronizing signal and a subcarrier and supplies the reference color frame information to the controller 12. The controller 12 supplies a control signal designated by the external device 3 to the main body 11 and generates a trigger 32 to drive a special effect provision device 2 synchronously with the reference color frame information given from the main body 11 and supplies it to the special effect provision device 2 via an output port 122. The special effect provision device 2 supplies the video signal provided with the special effect to a mixer amplifier 111 in the timing of the trigger 33. Thus, the phase of all video signals inputted to the mixer amplifier 111 is adjusted.
