1. a kind of method, including:

  • In response to the request from equipment, the first safe class that the equipment is supported is determined;

    The first safe class supported using the identified equipment will be encoded from satellite service provider'"'"'s received signalBe grouped at the first IP, wherein first IP groupings comprising it is from the satellite service provider, used identified theThe first safe class that one equipment is supported is come the data that encode, and wherein executes volume after determining the first safe classCode, and with other data are received from the satellite service provider, the coding continues;

    The first IP groupings of coding are sent at least the first equipment;

    In response to the request from the second equipment, the second safe class that the second equipment is supported is determined;

    In response to determining that the second safe class that the second equipment is supported is different from the first safe class that the first equipment is supported,The second safe class supported using identified second equipment will be encoded from the satellite service provider received signalBe grouped at the 2nd IP, wherein second IP groupings comprising it is from the satellite service provider, used identified theThe second safe class that two equipment are supported is come the data that encode, and wherein in the second safety for determining that the second equipment is supportedCoding is executed after grade, and with other data are received from the satellite service provider, the coding continues;

    AndWhile the first equipment continues to the first IP groupings of coding, the 2nd IP groupings of coding are sent at least secondEquipment;

    To be wherein encoded into from the satellite service provider received signal the first IP grouping the step of and will be from the satelliteService provider received signal is encoded into identical data of the step of the 2nd IP groupings using same satellite service, andWherein the first IP groupings are formed to the multicast received by multiple first equipment with the first safe class, Yi JiTwo IP groupings are formed to the multicast received by multiple second equipment with the second safe class.
