ABSTRACT:
A reproduced signal processing system is employed in an apparatus for recording and reproducing a television signal on and from a rotating recording medium with one field being recorded on each track by means of at least one head. A circuit delays the signal thus reproduced by a period equal to one half of one horizontal scanning period of the television signal. A gate circuit selectively passes both the delayed reproduced signal and the delayed reproduced signal. Horizontal synchronizing signal are separated from the signal passed by the gate circuit. A standard signal supplying circuit provides a standard horizontal synchronizing signal. The phases of the separated horizontal synchronizing signal and the standard horizontal synchronizing signal are compared. Detection of coincidence or non-coincidence of the two phases forms a gate signal for so controlling the reproduced signal which has passed through the delaying circuit.
