ABSTRACT:
Characteristic amounts in each small region of audio signals transmitted in the working system and the standby system are extracted by characteristic amount calculators6-1, 6-2. A characteristic amount comparator7compares the characteristic amounts and judges occurrence of fault of a fault. Characteristic amount difference calculators9-1, 9-2, ∥D∥ comparator10, and faulty system judging unit11judges the system having a fault. Majority decision processor12and significance judging unit13enhance the reliability of the judgement. Delay difference of audio signals between systems is roughly detected by sub-sampling audio signals of two systems and comparing them, and then accurately detected without sub-sampling. Delay difference between audio signals is adjusted by the detected delay difference.
