Abstract
PURPOSE: To prevent the slippage of a picture by a variable delay element which has the delay quantity controlled by pulses synchronizing with horizontal synchronizing signals in delayed input composite video signals.
CONSTITUTION: Composite video signals coming from input terminal 1 are supplied to horizontal synchronizing signal separator circuit 6 and PLL 7 to obtain clock pulses which are synchronized with horizontal synchronizing signals. These clock pulses are applied to N-bit CCD 5 to take out composite video signals delayed by time γ, and clock frequency components are eliminated by LPF 9. Since clock pulses are synchronized with the phase of horizontal synchronizing signals, delay time γ is followed to prevent the picture from being double even if they have time base fluctuation components such as reproduced composite video signals.
