发明名称 Decoder
摘要 A plurality of decoding programs respectively corresponding to each of a plurality of compression formats is stored in a memory card 18 attached to a slot 16. A CPU 20 determines whether or not a decoding program corresponding to a compression format of music data to be reproduced exists in a RAM 22a, and transfers the decoding program from the memory card 18 to the RAM 22a according to the determination result. That is, when the decoding program corresponding to the compression format of the music data to be reproduced exists in the RAM 22a, the same decoding program is not transferred. The music data is decoded by a DSP 22 according to the decoding program stored in the RAM 22a.
