<p><P>PROBLEM TO BE SOLVED: To reduce a power consumed by a memory, used by an encoding processing and a decoding processing, and to realize the lowering of a consumption power as a recording reproducing device. <P>SOLUTION: An encoder 113 and decoders 111 and 112 have memories 14 and 15 for holding intermediate data, when the encoder and the decoders are operated. A clock control section 115 controls so as to supply only the used memory with a clock, or controls the frequency of the clock supplied to the memory. A memory power-supply control section 18 controls so as to supply only the used memory with a power supply. When a battery is used as the power supply supplied to the recording reproducer and a trans-coding processing is conducted, the clock control section 115 stops supplying of the clock to the memory. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
