PPROBLEM TO BE SOLVED: To provide a digital demodulation technology which acquires more accurate data by reducing the error caused in the operation control of a tuner or demodulator, etc. PSOLUTION: A start timing determiner 80 determines the start timing 75 of the operation control of circuit components by a tuner controller 26 and a demodulation controller 41 in a time period composed of a guard interval 54 of a symbol and a separate sub-guard interval 53 of a separate symbol connected to the guard interval 54. An error corrector 36 corrects an error to be contained in a signal Si due to the operation control of the circuit components after a deinterleaving process disperses it. PCOPYRIGHT: (C)2008,JPO&INPIT
