METHOD AND APPARATUS FOR CALIBRATING THE PHASE OF A VIDEO SIGNAL |
摘要 |
The color burst of a first video signal is brought into a desired phase relationship with the color burst of a second video signal by generating a first number which is representative of the phase relationship between the burst of the second video signal and a calibration reference signal and generating a second number which is representative of the phase relationship between the burst of the first video signal and the calibration reference signal. The second number is compared with the first number, and the phase of the burst of the first video signal is adjusted automatically in a manner such as to achieve a predetermined relationship between the second number and the first number.
