One program (channel) is displayed on the full TV screen at the same time as one or more other programs are displayed in inset windows. Sound is from the main program only. This will allow you to play your Xbox/PS on the main display while you keep watching a TV show, movie, or other program in the second display. This supports up to 3 sub-screens at a single time so you can be watching 4 other things at a single time as you are on your main display!
