Abstract

PURPOSE:To suitably synthesize a sub-video corresponding to a main video by removing a referring signal to show which video is outputted from a main video output device, judging whether or not the referring signal satisfies the synthesizing conditions and communicating the effect do as to synthesize it to a video synthesizing device with a control device when the conditions are satisfied. CONSTITUTION:A control device 1 sets the conditions to synthesize a sub-video to a comparator 3 beforehand. From a main video output device, an output signal and a referring signal are outputted and inputted to the comparator 3. The comparator 3 judges whether or not the synthesizing conditions are satisfied and communicates the effect to the control device 1. The control device 1 commands a video synthesizing device 6 to synthesize the sub-video when the conditions are satisfied. When the judgement of the comparator 3 does not satisfy the conditions, the control device 1 commands the video synthesizing device 6 to output a main video only. Thus, since the video synchronizing device 6 can switch and output the main video and the synthesizing video, the sub-video can be suitably synthesized and displayed by matching to the timing of a main video.
