Abstract
An apparatus which depends on one of a plurality of master clocks as a timing source includes a timing-dependency-direction-identifier-extraction unit which detects an identifier indicative of a direction of timing dependency from a received signal with respect to each of the master clocks, a timing-quality-information-extraction unit which detects a code indicative of a timing quality from the received signal with respect to each of the master clocks, and a synchronization unit which selects the timing source based on the code indicative of a timing quality, and identifies a direction of timing dependency of the timing source based on the identifier indicative of a direction of timing dependency.
