Abstract
PURPOSE: To eliminate the disturbance of reproduced pictures by recording video signals, where same odd signals of odd or even field signals are continuous partially, on a magnetic tape, etc., where control signals are recorded at every frame period, synchronously with control signals.
CONSTITUTION: Synchronizing separator circuit 6 where input video signals from input terminal 5 are supplied to separate composite synchronizing signals and vertical synchronizing separator circuit 7 where composite synchronizing signals separated by circuit 6 are supplied to separate vertical synchronizing signals are provided, and further, framing synchronizing separator circuit 8 where composite synchronizing signals separated by circuit 6 are supplied to separate framing synchronizing signals is provided. Then, AND gate 9 which is connected to delay circuit 11 extracting framing synchronizing signals for a prescribed time from the recording start of video signals and FF circuit 12 which is triggerred by vertical synchronizing signals separated by circuit 7 and has the operation state regulated by framing synchronizing signals are provided, and framing control signals are outputted to output terminal 14 of FF circuit 12.
