PROBLEM TO BE SOLVED: To eliminate noise. SOLUTION: Data input to an encoding/decoding unit 21 is input to an error decoding detector 23. The detector 23 judges whether the input data is correctly decoded or not. For example, if the detector 23 judges that input audio data is not correctly decoded, the detector 23 does not output the audio data, or outputs data indicating no sound for muting. |
