ABSTRACT The present invention, in an error detection circuit suited for use, for example, in an error detection circuit for a digital VTR, is enabled to detect a position of error data without employing an error detecting code but by detection of an out-of- band component of a video signal and enabled thereby to make error detection even at a variable-speed playback. Also, the error detection circuit of the invention is provided with a peak detection circuit for detecting a peak value from an output of a filter detecting the out-of-band component of the video signal so as to correctly detect the position of error data through detection of a pattern of the peak values.
