PROBLEM TO BE SOLVED: To provide broadcasting services corresponding to an environment on the side of a receiver. SOLUTION: The transmitter transmits a command for operating the receiver and at least one of peripheral equipment and transmits a connection condition data which are conditions when executing this command. A receiving part in the receiver receives the connection condition data which are conditions when executing the command together with this command and a decision part in the receiver decides whether the relevant connection conditions are satisfied or not by analyzing the connection condition data. Thus, even when transmitting the printing command of an English conversation text from the transmitter, for example, on the side of receiving of this printing command, it can be decided whether a printer is connected to the relevant receiver or not. Therefore, the broadcasting services corresponding to the environment on the side of the receiver can be provided such that only when it is decided that the printer is connected, the printing command is executed. |
