DATA RECEIVING DEVICE, METHOD OF REPRODUCING SOURCE CLOCK USED FOR THIS, AND COMPUTER-READABLE RECORDED MEDIUM WHERE PROGRAM FOR EXECUTING THIS METHOD BY COMPUTER IS RECORDED

摘要

A source clock reproducing section (10) is provided with an operating section (2) for operating a controlled variable U for reproducing a source clock obtained by calculating the weighted mean of the remaining amount H of one or more buffers successively detected, multiplying the weighted mean by a prescribed sensitivity A, and adding a prescribed offset value, and an operation control section (5) that sets the manipulated variable to the one used for operating a controlled variable and capable of converging to the source clock quickly from the start of the reproduction of the source clock until the predetermined conditions under which a local clock (14) or a reproducing source clock approaches the frequency of the source clock are satisfied, and that sets the manipulated variable to the one by which the source clock can be reproduced stably after the conditions are satisfied.
