PROBLEM TO BE SOLVED: To provide a centralized control AV system in which different kinds of AV devices are mixed without being conscious of the differences among the devices for the operator of the system and of which the expandability is superior. SOLUTION: In the centralized control AV system, the music numbers, which correspond to the common code system that does not depend on the kinds of AV devices, are inputted from reservation machines 11 of boxes BX1, BX2,.... Prior to supplying these music numbers to different kinds of AV device groups 21 to 23, 31, 32, 41 and 42, the numbers are converted into the music numbers corresponding to the special code system of various kinds of the devices in code conversion processing sections 121 to 123, 131, 132, 141 and 142. Thus, the system, in which different kinds of AV devices are mixed, is constructed without being conscious of the differences among the devices for the operator of the system. |
