Abstract
A color television receiver suitable for two color television transmission systems, a color synchronization signal of a first frequency being transmitted in the first system (pal) at the rear threshold of the line synchronization pulses and being transmitted in the second system (secam) a color identification signal by modulation of the frequency of the color carrier, during a sequence of lines coinciding with the frame suppression interval, whose color identification signal exhibits, at least during part of each of said lines, a second frequency and a third frequency alternating from one line to the other, whose frequencies differ from each other and, at least one of whose frequencies differs from the first frequency, characterized in that the receiver comprises a system identification channel connected to the receiver input to identify the television transmission system in c odor from the received color television signal, said channel comprising barrier circuits for selecting the signals that appear in the frame blanking intervals, a means for suppressing signals of the first frequency and a means for detecting signals having a frequency in the group formed by the second and third frequencies, whose frequency differs to a greater extent from the first frequency.
