Patent ID: 8537939

Claim:
A reception apparatus comprising: spectrum inversion detection means for detecting the occurrence or absence of spectrum inversion in a received signal complying with the Digital Video Broadcasting-Terrestrial 2 standard known as DVB-T2, using a P 1 signal constituting said received signal; spectrum inversion means for performing a spectrum inversion process on said received signal if the occurrence of said spectrum inversion is detected at least by said spectrum inversion detection means; and demodulation means for demodulating said received signal having undergone said spectrum inversion process if the occurrence of said spectrum inversion is detected by said spectrum inversion detection means, said demodulation means further demodulating said received signal yet to undergo said spectrum inversion process if the absence of said spectrum inversion is detected by said spectrum inversion detection means, wherein said spectrum inversion means always performs said spectrum inversion process on said received signal regardless of whether the occurrence or the absence of said spectrum inversion is detected.
