S P E C I F I C A T I O N TO ALL WHOM IT MAY CONCERN: BE IT KNOWN that I, ALLEN J. TROST, a citizen of the United States and resident of Cupertino, in the County of Santa Clara and State of California, have invented a PILOT SIGNAL PROCESSING MEANS FOR VIDEO RECORDING APPARATUS of which the following is a specification. ABSTRACT OF THE DISCLOSURE A system is disclosed for processing a pilot signal in a video recording and reproducing apparatus so that the pilot signal can be used to provide automatic correction of the chrominance level for a head switching equalizer for a number of transducing heads, as well as for providing a contin- uous signal that can be used for a time base corrector for the color video signal. The apparatus also corrects internally produced phase errors and phase locks the pilot signal with the color burst of the video signal.
