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.

摘要： PROBLEM TO BE SOLVED: To simultaneously transmit control / monitor information to an optional relay stage while suppressing the processing delay time in relay stages.
SOLUTION: An AC1 field assigned to an ACI1 field of a broadcast TS packet in addition to basic information is specified to a TMCC storage field in an STL / TTL transmission packet. The AC1 field in the TMCC field in the transmission packet is used for transmission of e.g., the control / monitor information to simultaneously apply controlling / monitoring to each relay stage. In this case, simultaneous information stored in the AC1 field in the TMCC field of the transmission packet is automatically assigned to the AC1 field in the TMCC fields in the case of conversion into the broadcast TS packet and transmitted while being automatically assigned to the AC1 field in the TMCC filed in the transmission packet in the case of conversion into the transmission packet after transmission in a station, then the packet is automatically distributed to all the relay stages and it is not required to re-superimpose the information in each relay stage.
