1. method through the software in the public module upgrading digital broadcasting transmitter that uses to share by a plurality of digital broadcasting transmitters, said method comprises:

  • The digital broadcast signal of the public module of sharing by a plurality of digital broadcasting transmitters that reception comprises that special module with digital broadcasting transmitter separates;

    If need to confirm software upgrading;

    Then according to predetermined lastest imformation, based on the version of each module of broadcasting receiver be included in version in the digital broadcast signal determine whether to upgrade each module of digital broadcasting transmitter with the corresponding module of said each module;

    WithCollect the downloading data block that is used for the module of being upgraded from the digital broadcast signal that receives, with the module of formation upgrading,Wherein, predetermined lastest imformation comprises;

    the module release of the model of digital broadcasting transmitter, the manufacturer of digital broadcasting transmitter and digital broadcasting transmitter,Wherein, public module is sent out with second group first group the form that is different under the said special module, and perhaps the form with the group under the special module is sent out,Wherein, If public module is sent out with second group first group the form that is different under the said special module;

    The step of each module of digital broadcasting transmitter of then determining whether to upgrade comprises;

    if there be first group under the public module in the iterative software that the download service in being included in digital broadcast signal the starts circulation, then receive corresponding download message explanation;

    With the search module identical in the public module tabulation in being included in download message explanation with the module of digital broadcasting transmitter;

    And compare to confirm through version whether each module of digital broadcasting transmitter needs upgrading with the module of the version of the module that searches and corresponding digital broadcasting receiver;

    Wherein, The public module tabulation comprises the information about the module of being shared by two in a plurality of digital broadcasting transmitters perhaps more digital broadcasting transmittersWherein, If public module is sent out with the form of the group under the particular module;

    The step of each module of digital broadcasting transmitter of then determining whether to upgrade also comprises;

    organize accordingly if exist with the model of digital broadcasting transmitter in the iterative software that the download service in being included in digital broadcast signal the starts circulation, then receive corresponding download message explanation;

    Through using predetermined public module information, in the module of the download message explanation definition that receives, search for public module;

    With each module that compares the digital broadcasting transmitter that determines whether to upgrade through version with the module of the version of the public module that searches and digital broadcasting transmitter;

    Wherein, Predetermined public module information comprises one of information of describing among predetermined filename, additional lastest imformation file and the PrivateModuleByte, and said PrivateModuleByte is the message that is included among the ModuleInfoDescriptor that provides separately.
