PROBLEM TO BE SOLVED: To perform appropriate communication control, depending on whether communication quality must be held for each communication device.SOLUTION: A controller for controlling communication between one or more communication devices, and a plurality of other communication devices communicating with the one or more communication devices, performs allocation control of channels used for communication between one or more communication devices and a plurality of other communication devices, and based on the fact whether each of the plurality of other communication devices is in a state capable of allowing communication error, sets a threshold related to communication quality for each of the plurality of other communication devices, determines whether allocation of channels allocated to communication between one or more communication devices, and a plurality of other communication devices is changed, based on the value related to the current communication quality specified for each of the plurality of other communication devices, and a threshold set for each of the plurality of display devices, and changes channel allocation when a determination is made that channel allocation is changed.SELECTED DRAWING: Figure 1 |
