Abstract:
1. A reception apparatus for receiving an Orthogonal Frequency Division Multiplexing (OFDM) signal transmitting data in bursts for a service by time division, comprising: a tuner operable to select a specific channel for a service to be received; a demodulator operable to demodulate the OFDM signal; a Fast Fourier Transform (FFT) section operable to convert the OFDM signal output from the demodulator to a signal in frequency domain; an equalization section operable to equalize the signal in frequency domain output from the FFT section; an error correction section operable to apply error correction to the signal output from the equalization section, wherein, after the service to be received is specified when received data is the specified service to decode the specified service, transmission channel decoding is performed to a part to be decoded, of the specified service and a part prior to the part to be decoded, and when received data is not the specified service, the transmission channel decoding is not performed, the transmission channel decoding including each process applied by the FFT section, the equalization section, and the error correction section.
