PROBLEM TO BE SOLVED: To provide a video audio signal changeover device that can accurately obtain a switching point at which at least either of a video signal and an audio signal is switched and information with respect to the switching point. SOLUTION: The video audio signal changeover device 1 includes a control signal generating section 3 that generates a control signal according to an input, a video/audio changeover effect section 5 that replaces at least either of the video signal and the audio signal with other video signal or audio signal and attaches a video effect to the video signal, and a receiving signal analysis section 7 that receives the control signal and either of the video signal and the audio signal from the control signal generating section 3 and the video/audio changeover effect section 5, extracts the switching point of the video signal or the audio signal and at least either of the other replaced video signal and audio signal and analyzes the type of the extracted signal. |
