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 multiplex signal processing apparatus in a singal transmitting and receiving system includes at the transmitting side: a first amplitude-modulator for modulating a first carrier by a main signal to obtain a vestigial sideband, amplitude-modulated main signal; a second amplitude-modulator for modulating a second carrier which has the same frequency but differs in phase by 90.degree. from the first carrier by a multiplex signal to obtain a double sideband, amplitude-modulated multiplex signal; an inverse Nyquist filter for filtering this signal to obtain a vestigial sideband, amplitude-modulated multiplex signal; and an adder for adding the vestigial sideband, amplitude-modulated main and multiplex signals to obtain a multiplexed signal. The apparatus at the receiving side includes: a Nyquist filter for filtering the multiplexed signal; a carrier regenerator for regenerating the first and second carriers from the multiplexed signal; a main signal detector for detecting the main signal from the multiplexed signal passed through the Nyquist filter by using the first carrier; a filter for removing quadrature distortion from the multiplexed signal; and a multiplex signal detector for detecting the multiplex signal from the multiplexed signal passed through the filter by using the second carrier. By inverse Nyquist filtering the auxiliary signal in quadrature to the picture carrier, a normal synchronous receiver will produce a conventional television signal without distortion (crosstalk) caused by quadrature distortion of an auxiliary signal containing additional picture information while at the same time allowing relatively simple demodulation of the auxiliary signal in improved receivers without adding distortion.

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.
