Abstract
A wide screen television apparatus comprises a memory for storing a set of video sources, a circuit for tuning to the set of video sources and a video signal processor. The video signal processor is coupled to the memory and to the tuning circuit, and develops a wide screen multiple picture display by selecting any one of the set of video sources for generating a main picture of the display and by selecting all of the set of video sources for generating supplemental pictures of the display, for example as three POP's. A remote control can be activated for choosing the set of video sources and for selecting the main picture from among the supplemental pictures. The multiple picture display is modified in a manner which identifies which one of the supplemental pictures corresponds to the main picture. An on-screen display indicator can be generated for the supplemental picture corresponding to the main picture. In an alternative, the supplemental picture corresponding to the main picture can be repositioned on the display. In another alternative, the supplemental picture corresponding to the main picture can be modified in appearance.
