ABSTRACT:
A television receiver with PIP circuitry provides a snapshot feature for freezing the main video display in the PIP display inset by operation of a special key on a remote control keypad. With the television receiver operating normally (PIP deactivated), one operation of the special key switches the main video signal to the PIP input and freezes the PIP display in its largest size and in the position it occupied the last time PIP was activated. A video message informs the viewer that a snapshot feature is operational. A subsequent operation of the special key switches the PIP signal to the PIP circuitry and unfreezes the display as in normal PIP operation. A further operation of the special key deactivates the PIP circuitry.
