Region having a same size in a audio signal region of a transmission frame is allocated to each of an active engine and passive engine. The active engine reads out input signals written into regions of the frame, performs signal processing on the read-out signals, and writes resultant signals into the region allocated to the active engine. The passive engine reads out the input signals written into the regions, performs the same signal processing as the active engine on the read-out signals, and writes resultant output signals into the region allocated to the passive engine. When a flag of the active engine is indicative of a normal state, an output device reads out the output signals from the region allocated to the active engine, but, when the flag is indicative of an abnormal state, the output device reads out the output signals from the region allocated to the passive engine. |
