Abstract

PURPOSE: To make accurate interlaced scanning possible with a small number of signal connections, by supplying a vertical synchronizing signal, obtained by separating a horizontal synchronizing signal from a composite video signal, and a vertical driving signal from the outside.
CONSTITUTION: A composite video signal inputted to terminal 9 is supplied to synchronous circuit 10 which contains video amplifier circuit 2 and differentiating circuit. Circuit 10 separates a horizontal synchronizing signal from the video signal so as to supply a horizontal synchronizing signal to horizontal detlecting circuit 6. A vertical driving signal from terminal 9, on the other hand, is supplied to vertical deflecting circuit 7 and this driving signal secures a sufficient phase which enables interlaced scanning, and then possesses a pulse waveform sudden in rise. Consequently, accurate interlaced scanning can be realized by a small number of signal connections.
