PROBLEM TO BE SOLVED: To reproduce contents having a reproducing frequency limit. SOLUTION: An audio data file having a reproducing frequency limit is reproduced from a memory card 40 to be decoded by an audio decoder 12 and to be reproduced. A lapse time of a reproduction time for the file is counted based on a data amount transferred from a DSP 30 to the audio decoder 12. When the lapse time exceeds a prescribed time, the number of reproduction times is determined to be counted as one reproduction, and a value of a reproduction frequency CT is brought into decrement. When the requency CT reaches to zero, a reproduction operation for the audio file is prohibited on and after it. When an instruction except a usual reproduction operation is issued midway of the reproduction, the counting of the lapse time is stopped temporarily, or the counted lapse time is reset. |
