ABSTRACT:
A video display for a television apparatus has a wide format display ratio and is synchronized with a first video signal representative of first picture. A PIP processor is responsive to a second video signal representative of a second picture to define an auxiliary picture smaller in size than the video display. A FIFO line memory stores successive lines of video information representative of the auxiliary picture, which are combined with certain successive lines of video information representative of the first picture. A counter initialized at a time corresponding to the start of each horizontal line of the first video signal generates a variable time delay. A FIFO control circuit successively initiates a transfer of the lines of video information representative of the auxiliary picture from the line memory for combination with the video information representative of the main picture after the variable time delay. The variable time delay determines one of a plurality of horizontal panning positions of the auxiliary picture across all of the video display. A manually operable remote control can be used for adjusting the variable time delay.
