  • Circuit arrangement for detecting motion in a television picture
    Patent number: 4688089
    Abstract: To detect horizontally moving portions of a TV frame formed from two adjacent fields, the vertical local frequency at a vertical edge of the moving portion of the picture is measured with a narrow-band-pass filter circuit which is tuned to the local frequency of the comblike structure at ta vertical edge of staggered lines of the two fields of the frame. When such an edge structure is detected, the circuit delivers a detection signal.

  • System for TV transmission
    Patent number: 4620225
    Abstract: A TV transmission system having an increased picture quality. Depending on whether the picture to be transmitted is a still picture or a motion picture, the TV signals are derived either from the scanning of the scene or by interpolation from consecutive scanning lines. The scanning at the transmission side is performed at a higher number than the standard number of picture lines of the system.
