ABSTRACT:
There is provided a video cassette recorder comprising a delay element (1), a switching unit (2) for switching an output of the delay element (1), a logic unit (3) for controlling the switching unit (2), and a skew detection unit (4) for detecting a skew, wherein the delay element (1) shares a delay element used for vertical emphasis/vertical de-emphasis and for a comb line filter during a special replay. The video cassette recorder thus provides a fast-forwarding replay image, a rewinding replay image and a still image with improved skew distortion from a tape recorded in a long recording mode providing quintuple the recording time of a standard mode. This realizes an excellent special replay image at low cost without requiring an expensive circuit such as a TBC and the like.
