摘要： In a multiplex signal processing apparatus, in the band of a demodulated signal in which a carrier is amplitude-modulated in a vestigial side band by a main signal, another carrier is superposed which is identical in frequency to the first carrier but different in phase by 90.degree. is amplitude-modulated its double side bands by a multiplex signal which is different from the main signal and which is formed into a vestigial side band signal by a nyquist filter. At least either the frequency or polarity of the multiplex signal is inverted on the transmission side by a multiplier, an oscillator and a filter. At least either the frequency or polarity of the multiplex signal is inverted on the reception side by a multiplier, an oscillator and a filter. The reception side has a crosstalk reduction filter for removing crosstalk from the main signal to the multiplex signal.

摘要： In the television broadcasting system called letter box method, it is proposed to transmit an image having a larger aspect ratio than that of the existing broadcasting system by using some of the scanning lines of the existing broadcasting system, and transmit some additional information signal in the remaining portion. An offset value applied to the additional information signal at the transmission side must be removed completely at the reception side. Accordingly, at the reception side, in the scanning line in which an offset reference signal indicative of the offset value is transmitted, the offset reference value and a DC level reference value of the scanning line are detected, and these values are retained until a next offset reference signal is detected. By detecting a DC level of a scanning line containing the additional information signal, a difference from the DC level reference value previously detected and retained is obtained, and the offset reference value detected and retained previously is corrected by this difference. Thus obtained offset value is subtracted from the transmitted additional information signal.

摘要： A video signal processing circuit synthesizes a video signal and a graphic signal on the basis of a display switching control signal, inverts a synthesized signal on the time axis for each of a forward scanning period and a backward scanning period, and output a display signal. A speed modulating signal control circuit inverts the binarized display switching control signal on the time axis for each of the forward scanning period and the backward scanning period, expands the pulse width thereof, and feeds the display switching control signal to a speed modulating signal generating circuit. The speed modulating signal generating circuit subjects a display signal to first-order differentiation, inverts the polarity of a differentiated signal in the backward scanning signal, sets a portion, corresponding to the graphic signal, in the differentiated signal on the basis of the display switching control signal at a zero level, and generates a speed modulating signal.
