PURPOSE:To operate a digital signal processing circuit normally and to satisfy the processing even under the worst condition, by obtaining normal synchronizing signal as long as all digital signal trains to b received are not interrupted. CONSTITUTION:The digital signal processing circuit 101 is operated in synchronizing with a synchronizing signal 12 and processes digital signal trains 1, 2, 3. Processed digital signal trains 5, 6, 7 are outputted corresponding to the inputted digital signal trains 1, 2, 3. Thus, in this synchronizing signal reproducing system, if at least one digital signal train is normal out of the inputted digital signal trains 1, 2, 3 is normal, a synthesized signal 10 provides normal timing information. Since a timing pickup circuit 202 and a synchronizing signal generating circuit 203 are normally operated, a synchronizing signal 12 is normally obtained. |
