摘要

PROBLEM TO BE SOLVED: To provide a digital terrestrial broadcasting relay transmission apparatus which makes relay transmission possible while avoiding multistage connection with a microwave network and maintaining signal quality.;SOLUTION: A digital terrestrial broadcast wave of a speicfic channel is selectively received at a tuner 12. A digital broadcast signal (TS, TMCC/AC) is demodulated from a received signal at a demodulation part 13. Then an error correction is applied by decoding parts 14 and 15 to restore CN deterioration and decode. After TOT rewriting in consideration of a loss time required for signal processing at a TOT rewriting processing part 16, time division multiplex is performed by a multiplexing processing part 17 to reconfigurate a TS broadcast signal and then transmit from a TTL transmission part 18 to a nextstage relay station by a TTL wave. By arranging such a relay transmittion apparatus as this for an intermediate relay station, TTL 2-stage relay is disolved while maintaining the signal quality.;COPYRIGHT: (C)2004,JPO&NCIPI
