ABSTRACT OF THE DISCLOSURE This invention relates to a picture-in-picture type television receiver in which a sub-picture screen is provided within a main picture screen and the pictures on the main and sub-picture screens can be exchanged by means of a viewer operated control. According to this television receiver, when a command for exchanging the pictures is issued, if the picture displayed on the main picture screen is of a PAY channel (CABLE CHANNEL), the main and sub-channels cannot be exchanged with each other, and the exchange of the pictures is inhibited. The viewer is warned of this exchange inhibition for a predetermined time period. Thus, the user can utilize the television receiver more conveniently and is relieved of any anxiety when the pictures are inhibited from being exchanged with each other.
