Abstract
PURPOSE:To make it possible to reproduce excellent pictures regardless of the kind of a system by tracking-correcting and reproducing a magnetic tape recorded on a difference system and then by switching and using a deflecting current by partially modifying a deflecting circuit. CONSTITUTION:A video head is supported by an electromechanical converting element and displaced in the turning-axial direction for tracking correction. Once a video signal obtained by tracking correction is supplied to video input terminal 13, part of its has its synchronizing signal extracted by synchronizing separating circuit 14 and it is sent to vertical deflecting circuit part 11 and horizontal deflecting circuit part 12. Circuit part 11 consists of vertical oscillation circuit 16 generating a saw-tooth wave, vertical amplitude adjusting alternation circuit 17 adjusting the amplitude of the saw-tooth signal, vertical deflecting coil 18, etc., and circuit 17 is equipped with amplitude adjusting variable resistors 21 and 22, which are used for corresponding systems by being switched by being switched by change-over switch 23. Circuit part 12 has its amplitude adjustment made in exactly the same way of switching change-over switch 31. Consequently, it is made possible to reproduce picture of good quality displayed over the entire CRT screen.
