  • Patent number: 6588014
    Abstract: A digital broadcasting system capable of quickly acquiring long term program information. An SI generating part SG2 generates a long term program information S_EIT which is multiplexed in a transport stream TS2 only. The SI generating part SG2 gives information on whether the long term program information S_EIT is present or not for each service to other SI generating parts SG1 and SG3. The SI generating parts SG1 and SG3 multiplex the given presence information in transport streams TS1 and TS3. In this way, the presence information is multiplexed in all the transport streams. Therefore, the presence information may be acquired whichever transport stream is being received. If the presence information is retained beforehand, the information may be quickly used as required.
