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.
Claims7
A video cassette recorder for performing a special replay of a signal recorded in a mode providing quintuple the recording time of a standard recording mode, said video cassette recorder comprising:
- a delay unit for delaying a reproduced signal by any of 0.2H, 0.4H, 0.6H, 0.8H, and 1H;
- a skew detection unit;
- and
- a switching unit for selecting any of said reproduced signal and an output of said delay unit in response to any of a signal detected by said skew detection unit and a magnetic head switching signal.
A video cassette recorder for performing a special replay of a signal recorded in a mode providing quintuple the recording time of a standard recording mode, said video cassette recorder comprising:
- a delay unit for delaying a reproduced signal by any of 0.4H, 0.8H, 1.2H, 1.6H, and 2H;
- a skew detection unit;
- and
- a switching unit for selecting any of said reproduced signal and an output of said delay unit in response to any of a signal detected by said skew detection unit and a magnetic head switching signal.
A video cassette recorder for reproducing a still image of a signal recorded in a mode providing quintuple the recording time of a standard recording mode, said video cassette recorder comprising:
- a pair of magnetic heads for recording and reproduction having a width wider than a pitch of recorded tracks;
- a delay unit for delaying by 0.2H a signal reproduced by one of said pair of magnetic heads for recording and reproduction;
- and
- a switching unit for selecting any of a signal reproduced by the other of said pair of magnetic heads and an output signal of said delay unit in response to a head switching signal.
