The USE decoder includes a gate circuit that extracts the dropout detection signal only during the audio signal period of the MUSE signal, and generates an output when the time length of the output signal of the gate circuit is larger than the correctable dropout time length. 1. A MUSE decoder comprising: a dropout time detection circuit that performs a dropout time detection circuit; and a muting circuit that performs a mute operation on an audio signal reproduced from the MUSE signal when the output of the detection circuit is obtained.
