<p>A picture-within-a-picture television receiver includes circuitry for displaying a reduced-size frozen image developed from an auxiliary signal (Y) as an inset in the main image. To develop signals representing two fields of the compressed auxiliary image, the system includes circuitry (200,250,254,260) which processes first and second groups of successive horizontal line intervals of one field of the auxiliary video signal to develop signals (Y') representing mutually corresponding horizontal line intervals in two successive fields of the compressed auxiliary video signal.</p> |
