    摘要: A control system, for example, for a television receiver comprised of a monitor and a tuner has a plurality of sources of control commands, such as, remote control command receivers associated with the television monitor and tuner, respectively, and a manual control device or keyboard associated with the monitor, a plurality of input terminals connected to the control command sources, respectively, through independent paths and each of which is assigned a predetermined priority in relation to the other input terminals, and a controller for selecting one of the control commands in the order of the predetermined priorities assigned thereto when such control commands are simultaneously received at the respective input terminals, and for producing a control signal for the monitor and/or tuner in correspondence with the selected control command.

    摘要: A raster distortion correction circuit for correcting both pincushion distortion and trapezoidal distortion of a raster on a cathode ray tube. A parabolic-shaped signal and a sawtooth-shaped signal, both having frequencies equal to the vertical deflection frequency, are supplied to the correction circuit. The amplitude and polarity of the sawtooth-shaped signal is selectively adjusted, and the adjusted sawtooth-shaped signal is combined with the parabolic-shaped signal and supplied to a current modulator. A horizontal deflecting current flows through the modulator and is thus modulated by the combined parabolic-shaped signal and adjusted sawtooth-shaped signal, the modulated horizontal deflecting current being supplied to a horizontal deflection coil included in the horizontal deflection circuit for the cathode ray tube. The parabolic-shaped signal component corrects the pincushion distortion and the adjusted sawtooth-shaped component corrects the trapezoidal distortion.
