    • A broadcast system BS includes a broadcast apparatus 1 and a reception apparatus 2. The broadcast apparatus 1 first receives and stores therein a proxy request PR including at least an identifier assigned to the reception apparatus 2 and a command to be transmitted to the reception apparatus 2. Moreover, the broadcast apparatus 1 extracts the set of the identifier of the reception apparatus 2 and the command for the reception apparatus 2 from the proxy request PR stored therein, and assembles a command packet from the set of the identifier and the command. Then, the broadcast apparatus 1 generates a stream in which the assembled command packet is multiplexed, and sends it out to a broadcast channel. The reception apparatus 2 separates the command packet from the stream sent out to the broadcast channel, and restores the set of the identifier and the command of the reception apparatus 2. Then, the reception apparatus 2 determines whether or not the disassembled command is destined for the present reception apparatus based on the pre-stored identifier of the present reception apparatus and the disassembled identifier of the reception apparatus 2. If so, the reception apparatus 2 stores therein the command destined for the present reception apparatus. The reception apparatus 2 executes the command, which has bee stored as described above.
    • 广播系统BS包括广播设备1和接收设备2.广播设备1首先接收并存储包括至少分配给接收设备2的标识符的代理请求PR和要发送到接收设备2的命令 此外,广播装置1从存储在其中的代理请求PR提取接收装置2的标识符集和接收装置2的命令,并从标识符和命令的集合中组合命令包。 然后,广播装置1生成组合的命令包被复用的流,并将其发送到广播信道。 接收装置2将命令包与发送到广播信道的流分离,并恢复接收装置2的标识符和命令的集合。然后,接收装置2判断分解的命令是否发往 本接收装置基于本接收装置的预先存储的标识符和接收装置2的拆卸标识符。如果是,则接收装置2存储指定给本接收装置的命令。 接收装置2执行如上所述存储的命令。
