ABSTRACT:
A television receiver is provided which includes a vertical deflection circuit which causes interlacing of an interlaced video signal having two fields each with an integral number of scan lines. The vertical deflection circuit including a jog circuit coupled to a vertical deflection yoke, which jog circuit causes a change in current through the vertical deflection yoke during reception of one of the fields. This change in current causes the fields to interlace with each other when scanned on a picture tube.
