Abstract
A television receiver has a main, or regular, display; a picture-in-picture display; and an on-screen menu display for adjusting various television operating parameters, including those which are channel or source related, such as channel labeling, source labeling and on-screen program guide operation. When a channel or source related menu is displayed for operation on channel or source related functions, the channel or source operated upon is displayed in the picture-in-picture display and the main display may be blanked to present a more legible background for the menu.
