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.
