摘要： An acquirer acquires abnormality information indicating that an abnormality has occurred in equipment provided in a conference room. The equipment is, for example, a display device such as a display or a projector. A conference information generator generates conference information indicating a progress status of a conference which is carried out in the conference room by processing information output from a device provided in the conference room. An information transmitter determines a first timing which is a timing at which abnormality-relevant information which is information to be transmitted due to occurrence of the abnormality is transmitted using the conference information and transmits the abnormality-relevant information to the equipment or another device at the first timing.
