A sampling clock phase control system includes, at a transmitter side, a circuit for generating a first phase reference signal phase-locked with a color burst of an input color television signal, and a multiplexer for multiplexing the color television signal encoded by a first sampling clock and the first phase reference signal and outputting the multiplexed signal to a channel. The control system includes, at a receiver side, a circuit for generating a second phase reference signal phase-locked with a color burst of a decoded color television signal, a phase comparator for comparing the phases of the first and second phase reference signals, and a circuit which is feedback-controlled by an output signal from the phase comparator and generates a sampling clock for D/A-converting a decoded reception signal.
