Abstract
A turnaround control arrangement for a color video recording and playback system, in which a color burst frequency at turnaround time is recorded during a certain vertical blanking interval in a distinct pattern; and in which, in playback the tape reversal operation is initiated at least partially under control of this distinct pattern. This 'turnaround flag' is also used to control the insertion of the sound signal carrier frequency of the system during turnaround, thereby to reduce the noise due to the loss of the recorded sound signal during turnaround in playback.
