In a PAL-SECAM color television receiver comprising a transcoder for converting a SECAM signal into a signal which is processable by a PAL decoder, and a systems change-over switch which can be operated by a SECAM identification circuit for automatically adapting the receiver to the reception of or SECAM signals, a blocking circuit which can be operated by a identification signal is used, which blocking circuit in the event a signal is received blocks the output signal from the SECAM identification circuit so that also in the event that a disturbed PAL signal is received said output signal does not adjust the systems change-over switch to the incorrect position.
