Abstract

PURPOSE:To enhance the transmission efficiency by giving correction to the self- terminal clock signal so that the self-terminal clock signal may be in agreement with the center point between the synchronous signal transmission time and the reception time. CONSTITUTION:The 2nd terminal comprises transmission device 11, reception device 12, clock generation device 13, transmission timing control unit 14 and timing comparison device 15 respectively. And the 1st terminal consists of transmission device 1, reception device 2, clock signal generation device 3 and transmission timing control unit 4 each. At the 2nd terminal, the reception time is referred to as T4 for the synchronous signal sent from the 1st terminal. And the nearest clock signal generation time subsequent to T4 is referred to as T5. Then the synchronous signal is transmitted at time T6 obtained from T6-T5 T5-T4, and at the same time the self-terminal clock signal is corrected so that the self-terminal clock signal may be in agreement with the center point between the synchronous signal transmission time and the reception time. In this way, the synchronization of the clock signal is secured via only the 1-bit synchronous signal, thus increasing the transmission efficiency.
