  • Patent number: 5541780
    Abstract: Helical-scan video tape playback apparatus compensates for the skew generated during special reproduction operations (e.g., search functions) in the long-play mode. Video reproducing circuitry generates a first video signal; and a delay line supplies a second video signal in delayed response to the first video signal, the delay being one-half a horizontal scan line. During special reproduction operations in the long-play mode, a skew compensating device supplies an output video signal responsive to the first video signal when a first condition of a skew jump indication signal obtains and responsive to the second video signal when a second condition of the skew jump indication signal obtains. A frequency divider responds to an envelope comparison signal generated by comparing with a prescribed level the signals picked up by long-play heads and generates a square wave the fundamental frequency of which is half that of the envelope comparison signal.

  • Patent number: 5486873
    Abstract: The present invention is an analog screen-art circuit for displaying a video signal resembling a picture on a screen. The screen-art circuit includes a video signal processor having a color killer circuit for eliminating chrominance signals in a composite video signal. The screen-art circuit also includes an art mode selector for controlling the operation of the screen-art circuit, a number of serially connected delay elements for delaying the signal generated by the video signal processor by respective 1H periods and a switch for selectively switching the signals generated from the video signal processor and the 1H delays when operating in the art mode. The switch is responsive to a control signal provided by a control signal generator which logically combines a number of signals, one of which is based on a composite sync signal generated from the video processor. According to one embodiment of the invention, the other of the two signals is a head switching signal which is commonly found in most VCRs.
