Abstract: PURPOSE:To extend the application of the TV synchronization by sampling with the frequency of multiplication of the TV frame frequency by a rational number, to transmit the TV signal at a transmission rate within the spe cifications by a TV synchronization of excellent picture quality. CONSTITUTION:A PLL2 generates the sampling frequency from the TV signal of the image picked up by a camera 1.
