された映像信号のドロップアウト補償装置。a delay circuit that delays the original input video signal by at least one thousand cycles, a switch circuit that selectively takes out the output of the delay circuit and the original input video signal, and detects a dropout section of the original input video signal. It has a dropout detection circuit and a hold circuit that obtains a signal that is in one state from the leading edge of the detection pulse from the dropout detection circuit to the horizontal planking section of the original input video signal,
A dropout compensation device for a video signal, wherein the output signal of the delay circuit is taken out from the switch circuit in place of the original input video signal when the output of the hold circuit brings the skewer into the first state. .
