PROBLEM TO BE SOLVED: To easily discriminate, the deterioration of an error rate by permitting a digital broadcasting receiver to detect the error rate of a code and the related value as received environment values, displaying the received environment value which a received environment value detection means detects and informing a user of it. SOLUTION: Plural digital audio broadcasting DAB is received by an antenna 11. A DAB tuner 12 selects one DAB which a user selects among DAB that can be received by the antenna 11 by tuning. Then it is sent to an A/D converter 13. In the A/D converter 13, the OFDM signal of DAB is inputted from the DAB tuner 12 and it is analog/digital-transformed and it is outputted to a received environment value detection means DSP: 14. The output signal is Fourier-transformed at high speed, is parallel/series-transformed in DSP: 14 and it is transformed into demodulation data. DSP: 14 corrects an error when it exists in a code after demodulation from the A/D converter 13 and outputs it to a D/A converter 15. |
