Abstract

Receiving apparatus to be used in an installation for the transmission of color television signals, in which the transmitted signal comprises a signal component that refers substantially to the brightness of the scene, and further comprises a signal component consisting of a wave quadrature-modulated auxiliary carrier with two signals of different bandwidths, each of which consists of a certain combination of the signals that refer to the respective color components of the scene, combinations that are such as to obtain, by operations linear signals, color difference signals of two signals of different bandwidths, characterized in that the modulated auxiliary carrier wave is supplied to at least two synchronous modulators, preferably of high level, the auxiliary carrier wave being demodulated in the direction of the axis of the different color difference signals with respect to the frequency uences within the frequency range of the lower bandwidth signal, and the auxiliary carrier wave is also demodulated with respect to the external frequencies of the frequency range of the smaller bandwidth signal, the resultant stop being applied to this signal. Demodulation mentioned in the last term to one or more of the color difference signals, with a phase corresponding to the phase of the arrest that would be obtained by demodulating the auxiliary carrier wave in the direction of the axis of the greater bandwidth signal.
