ABSTRACT OF THE DISCLOSURE Disclosed in a variable aspect ratio television receivier, which receiver a non-standard television signal containing an identification signal superimposed upon video signal for the first several horizontal scann- ing lines in the vertical scanning period. An AND gate is adapted to detect the aforementioned identification signal as such if the signal has a frequency within a range sufficiently high compared to the horizontal scann- ing frequency and lower than and sufficiently distinguish- able compared to the color sub-carrier frequency and a sufficient level within a range conforming to the broad- casting standard continuously for a predetermined period in its predetermined section, and the output of the AND circuit is used to drive a deflection amplitude switch relay circuit for controlling the horizontal deflection amplitude of the image reproduction.
