Abstract

PROBLEM TO BE SOLVED: To put video and audio on the air in linkage and independently by receiving the output of a touch panel provided with an input function for changeover-controlling video signals and audio signals and changeover-controlling a video switcher and an audio switcher. SOLUTION: In the video signal switching system of the news of a television studio, a 16-divided video generation part 1 respectively reduces the 16 pieces of video signals A-P and displays them on one screen. The touch panel 3 is provided with plural control input parts corresponding to the plural pieces of the display of a display 2 and information touched by an operator from the above is delivered to a control part 4. The control part 4 edits the information touched by the operator and controls the video switcher 5 and thesaudio switcher 6 based on it and the video switcher 5 and the audio switcher 6 are switched by control from the control part 4 and output video signals and audio signals to be put on the air. Thus, a news changeover and send-out system capable of performing various changeover is obtained.
