Abstract
Color television device, of the type in which two color signals are transformed, before their emission on the same guide, into two sequential signals alternating to the line frequency, by means of a switch having two inputs in the which signals are respectively applied, and an output to which the two signals are directed alternately, while in the reception the two received sequential signals or two sequential signals obtained, from the two received sequential signals, are separated by means of a switch having at least one input in which are applied the signals to be separated and at least one output assigned to one of the signals to be separated, characterized in that during the emission an identification signal is injected, directly or indirectly, in at least one of the inputs, which will be called first entry, of emission switch during recurring periods, called s of control, each of which is undertaken in a frame-suppression interval, because the emission switch is commanded so that it changes state regularly to line frequency at least between the beginning of each control period and the beginning of the suppression-frame interval containing the following control period, and because the reception switch is controlled by a device, attached to a receiver channel, called a control signal, which provides it during said control periods with a signal called control signal, which is a function of the phase of the reception switch in relation to the phase of the emission switch, said control device being arranged in such a way that it causes the change of state of the reception switch outside the periods regularly at line frequency. of control and, during periods of control, maintains or breaks the regular alternation of these changes of state, depending on the signal provided by the control path, so that the reception switch is in phase with the transmit switch at the end of each control period.
