Abstract
PURPOSE: To eliminate the incapability for extraction of the reference pulse as well as secure the constant position at all times for the output picture image of the device, by detecting the piling position of the color burst signal and then varying the phase of the horizontal synchronous signal.
CONSTITUTION: Color TV signal 22 is applied to synchronous signal isolator circuit 24 and burst signal gate circuit 26, and the horizontal synchronous signal isolated through circuit 24 is applied to burst gate pulse generator 28 plus multivibrators MV5 and MV30 each. The output of generator 28 drives circuit 26 to obtain color burst signal 9, and signal 9 is supplied to level detector 32 to obtain detection signal 34. Signal 34, reference subcarrier signal 40 and output 35 of MV5 are applied to phase difference detector 36 to obtain output signal 37. Output 37 is then applied to MV30 to give modulation to output pulse 42. Then output 42 is applied to reference pulse extractor 11 to obtain the referenc pulse. At the same time, reference horizontal signal 23 is supplied to MV31, and the output 27 is applied to reference pulse extractor 12 to obtain reference pulse 29 of the reference side.
