ABSTRACT:
A digital process for controlling the correct reproduction of a composite television signal and in particular of a composite color television signal comprising sequential-type chrominance signals, transmitted or recorded on an information-carrying medium such as a videodisk in which binary-coded pulsed signals are inserted during available intervals of the line scanning return, the binary value of these pulsed signals representing a particular state to be controlled. This value is detected during the process reproducing the composite television signals to make the particular state to be controlled dependent on this value. A first coded pulsed signal may be used for identifying the two components of the chrominance signals. A second coded pulsed signal may be used for identifying the face read of a transparent videodisk having information recorded on both its faces.
