PROBLEM TO BE SOLVED: To surely perform, in the event of occurrence of a specific interruption factor in a slave device, interruption processing corresponding to the specific interruption factor in a master device. SOLUTION: A PDA 70 that is the master device generates and outputs an interruption factor mask setting command to a tuner card 10 that is the slave device. In response thereto, the tuner card 10 generates and outputs an interruption signal to the PDA 70 only when a specific interruption factor 5A of a plurality of interruption factors occurs, to thereby execute processing for making the PDA 70 execute the corresponding specific interruption processing. The PDA 70 receives from the tuner card 10 the interruption signal which is generated only in the occurrence of the specific interruption factor A5, and executes, in response thereto, the corresponding specific interruption processing without confirmation for interruption factor to the tuner card 10.
