    Abstract: PURPOSE:To facilitate the circuit integration of a video circuit by revising only a data corresponding to an adjusted item among plural adjusting items and transferring the data of all the plural adjusting items serially. CONSTITUTION:A serial data is supplied to a shift register 101 from a deflection circuit 32 in the unit of 65 bits and a blanking pulse Pb is supplied as a clock pulse. The data is converted into an analog voltage by a D/A converter 103 at every adjustment item and the analog control voltage of each adjustment item is extracted. Then the adjustment control voltage of the sound volume and sound quality is fed to electronic control circuit of a preamplifier 23 and the adjustment control voltage of other item is supplied to each electronic control circuit of a video circuit 14. Since the data of each item are transferred serially for the adjustment, it is enough to add one pin for the data in case of circuit integration of the circuit 14 and then the circuit integration is facilitated.

    Abstract: PURPOSE:To reduce noises without using any large-capacity memory and without spoiling the fineness so as to make a movement detecting circuit omittable, by detecting field or frame differences from ones, whose amplitudes are smaller than a prescribed one, of the signals of high-frequency components. CONSTITUTION:Means 2 and 4 which separate video signals into 1st signals having low-frequency components and 2nd signals having high-frequency components, means 5 and 8 which separate the 2nd signals into 3rd signals having amplitudes larger than a prescribed level and 4th signals having amplitudes smaller than the prescribed level, means 11-13 which detect 1-field or 1-frame signals on the 4th signals and obtain 5th signals, and means 3 and 7 which combine the 1st, 3rd, and 5th signals, are provided. As a result, high-frequency signal components can be compensated and deterioration of the fineness of pictures can be eliminated. Moreover, no large-capacity memory is required as a field or frame memory and a movement detecting circuit can be omitted.
