<p><P>PROBLEM TO BE SOLVED: To provide a decoding method and a decoding device, and a program therefor that can reduce power consumption accompanied by decoding processing. <P>SOLUTION: A clock control section 11 predicts the number of clocks needed for processing from a variable modulation and demodulation section 13 to a deblocking filter 23 based upon header data etc., of encoded data. The frequency of a clock signal supplied from a clock control circuit 7 to a CPU 8 and a voltage supplied from a power source 6 to the CPU 8 are controlled based upon the prediction result. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
