Effect switcher and switcher system

A switcher system, comprising:

• video mixing circuitry that includes:
• internal busses defining cross points;
• an input terminal configured to receive a plurality of first video signals and supply the plurality of first video signals to first corresponding cross points of the cross points;
• a video signal generation circuit configured to generate a second video signal;
• and
• a storage connected to the video signal generation circuit through a dedicated connection, and configured to
• store the second video signal,
• supply the second video signal to second corresponding cross points of the cross points, and
• output an electrical signal that carries the second video signal;
• control circuitry coupled with the video mixing circuitry and configured to:
• control display of a Graphic User Interface (GUI) screen;
• and
• control an operation of the video mixing circuitry in response to a user operation of the GUI screen;
• an output terminal configured to output (i) a plurality of video signals from at least one of the first corresponding cross points or the second corresponding cross points and (ii) information for designating a display region of an image of the second video signal on a screen to electrical-to-optical conversion circuitry;
• and
• the electrical-to-optical conversion circuitry configured to output an optical multiplexed signal, the optical multiplexed signal carrying (i) the plurality of video signals from the output terminal and (ii) the information for designating the display region of the image of the second video signal on the screen.
