ABSTRACT:
Data input to an encrypting/decoding portion are input to an erroneous decoding detector. The erroneous decoding detector judges whether the data input are correctly decoded or not. For example, if it is judged that audio data input are not correctly decoded, the erroneous decoding detector does not output the audio data or outputs data indicating silence, thereby executing mute processing.
