  • Digital video effect equipment
    Patent number: 4240112
    Abstract: Digital video effects equipment for providing special effects by controlling the number of quantization levels for each sample of an incoming television video signal. Each video signal sample is converted into a digital signal comprising a predetermined number of binary digits. A gradation modification circuit decreases the gradation represented by the digitized video signal and the decreased gradation signal is reconverted to an analog signal. The resultant special effects gives the video picture an oil-painting-like impression.
    Type: Grant

    Date of Patent: December 16, 1980
    Assignee: Nippon Electric Co., Ltd.
    Inventors: Masao Inaba, Atsumi Sugimoto, Shigeru Miyahara
  • Frame synchronizer having a write-inhibit circuit
    Patent number: 4231063
    Abstract: A frame synchronizer for a television receiver in which the incoming television signal is digitized and stored in a memory, includes a circuit for generating a write-inhibit control signal for inhibiting the write-in of a digitized second television signal into the memory between the switchover from a first television signal to the second television signal and the beginning of a complete frame of the second television signal.

  • Delay compensator for a television signal
    Patent number: 4218705
    Abstract: Delay compensation apparatus for minimizing the delay differences between a video signal transmitted through a plurality of frame synchronizers, which delay the video signal, and a normally undelayed audio signal, the audio and video signal making up a complete television signal. Combinations of discreet delay intervals are imposed on the audio signal such that delay differences between the audio and video signal are minimized to the extent that the negligible remaining delay difference does not degrade the reproduced television picture.

  • System for reducing transmission problems in a parallel digital data transmission system
    Patent number: 4181914
    Abstract: A digital transmission system wherein a signal to be transmitted is represented by a plurality of parallel data bits, each of said data bits having a positional significance ranging from a most significant data bit to a least significant data bit. Each of said data bits are assigned to one of a plurality of data transmission highways based on the positional significance of the data bit. Failure of a particular highway results in a reassignment of the data bits to the highways so that transmission degradation is minimized.

  • Phase locking system for television signals using a digital memory technique
    Patent number: 4007486
    Abstract: A phase locking system locks at least one incoming composite video signal to the synchronizing signals of a second, reference wave. The incoming signal is strobed at a rate dependent upon the incoming color subcarrier into a memory, essentially on a field-by-field basis. Circuitry is provided by grouping the fields on a repeating field-tagged basis (groups of four for the NTSC signal format) to maintain signal integrity.
