Abstract
A picture-in-picture type television receiver in which a sub-picture is displayed inset into a main picture. In the television receiver of this invention the viewer, by operating a single control switch, can cause the receiver to display as the sub-picture either a moving picture or a still picture taken from either the main picture or the sub-picture at a selected point in time, at the viewer's option. When the still picture is taken from the main picture, a new still picture is displayed each time the control switch is operated, whereas when the still picture is taken from the sub-picture, the display of the still picture and the display of a real moving picture are alternately carried out each time the control switch is operated.
