  • Publication number: 20230191256
    Abstract: An example of a server receives first event data from an information processing apparatus. The server stores therein event management data including event state information that indicates whether a second event has already occurred or has not yet occurred. When receiving a request from the information processing apparatus, the server transmits at least one piece of second event data to the information processing apparatus. The at least one piece of second event data includes second event data based on event management data in which the event state information indicates that the second event has already occurred and/or second event data to be transmitted when the second event data stored in the first storage area is insufficient. Upon receiving the third event data indicating that the second event has occurred, the server updates the event state information so as to indicate that the second event has already occurred.

  • Publication number: 20140085061
    Abstract: According to a related remote control system, a remote control processing may occur even during an operated side terminal is in an emergency situation. An operated side terminal transmits, to a relay server, reception status information identifying a reception status for a remote control. Upon receiving a remote control request from an operating side terminal, the relay server determines whether or not a remote control is permitted based on access permission information which includes a pair of an operating side terminal permitted to remote control and an operated side terminal, and additionally, determines, based on reception status information, whether or not the operated side terminal currently accepts the remote control. Based on the determination outcomes, the relay server transmits, to the operated side terminal, a control message related to the remote control, based on which the operated side terminal provides a service.
