• the controller being further adapted for controlling the video formatter to:
• cause the single screen to be in a multi-view state where a video from the second video signal is displayed with a video from the first video signal on the single screen for a first time period;
• cause the single screen to be in a single-view state, after the first time period, where a video from the first video signal is displayed alone on the single screen for a second time period longer than the first time period;
• and
