Abstract

The present invention provides a switching method of the different display windows of a TV. Before the switching, the TV displays the TV programs, received from the broadcast system and a server, in a main window and a sub-display window respectively, and the switching method includes the following steps that: the TV and the server determine the channel identifiers of the TV programs displayed by each other; the TV displays the TV programs, received from the broadcast system and the server, with the channel identifiers of each other using the first display window and the second display window respectively. By the present invention, the sources of the contents displayed respectively in the first display window and second display window do not change, thereby maintaining the respective display quality (including resolution and picture size) of the two display windows unchangeable before and after the switching.
