  • Patent number: 6956812
    Abstract: A reception apparatus for OFDM signals having a short initial rise time since start of reception until outputting the sound and/or a picture. An OFDM reception apparatus 1 of the ISDB-T standard presets the TMCC information at the outset in a memory 19 in association with each broadcasting station. This TMCC information contains the information on the RF frequency and the guard interval length, time interleaving pattern information, the information on the carrier modulation scheme and the information on the code rate of the convolutional code. When a user selects a broadcasting station, a control circuit 18 reads out the TMCC information associated with the broadcasting station from the memory 19. The control circuit 18 affords the read-out TMCC information to each circuit to set e.g., the guard interval or the carrier modulation scheme.
