Abstract
An apparatus for reproducing a system clock provided with a reproducing unit for reproducing a first time reference clock T , a generating unit for generating a system clock Sck, a generating unit for generating a second time reference clock T , a synchronization control unit for minimizing, based on the clocks T and T , the deviation between these clocks, a first calculating unit for calculating a difference between counts of the clock T counted in a predetermined time interval, and a second calculating unit for calculating a difference between counts of the clock T counted in a predetermined time interval, the outputs of the calculation of the differences being input to the synchronization control unit to minimize the deviation between the clocks, whereby it becomes possible to reproduce high quality data even when switching channels from one node to another node when reproducing digital data from a plurality of sending side nodes at a receiving side node.
