Background
Many products for conference collaboration (e.g., video conferencing, presentation switchers), etc. support multi-window functionality, i.e., displaying content from multiple video sources simultaneously through multiple windows on the same screen. In some multi-window layouts of the screen, the sub-windows are not equally positioned, for example, a sub-window occupies a larger area, or a sub-window is superimposed in front of the rest of the sub-windows, and we refer to the sub-window positioned more prominently as the main window.
Currently, there are two methods for displaying the main window: 1. presetting, namely presetting that a main picture is fixedly matched with a certain video signal; 2. and manually selecting, wherein the user matches the main window to a required certain video signal through manual selection. The two methods are not flexible enough or complicated to operate, and the video signal which is accessed emergently cannot be played on the main window immediately.
