Abstract

PURPOSE:To obtain a color VTR having color phase irregularity improve greatly by making its pilot burst system interchangeable for that of a conventional device. CONSTITUTION:In a horizontal synchronizing signal equivalent period during recording, pilot burst signal Sp is added to chrominance signal Ss, and Sy, it is inserted by being inverted to chrominance signal Ss and burst signal Sb at intervals of 1H in the equivalent period of horizontal synchronizing signal Sh of luminance signal. For reproduction, the phase of this inverted pilot signal Sb is restored to the original phase and APC is exercised by this pilot burst signal of the restored phase.
