Abstract
A method of driving a CCD semiconductor delay line capable of providing a good delay characteristic without externally supplying a clock signal. An intermittent reference signal is extracted from the color burst signal of an inputted television signal. Using the intermittent reference signal, a continuous reference signal is generated by a phase locked loop. The continuous reference signal drives a CCD semiconductor delay line to delay the television signal.
