Moreover, the broadcast apparatusextracts the set of the identifier of the reception apparatusand the command for the reception apparatusfrom the proxy request PR stored therein, and assembles a command packet from the set of the identifier and the command. Then, the broadcast apparatusgenerates a stream in which the assembled command packet is multiplexed, and sends it out to a broadcast channel. The reception apparatusseparates 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.
