Abstract

A controller of an IRD generates a provisional ID for uniquely identifying an Event within the unit. Then, an Event within the unit is read from a Resource Schedule Board (RSB), and a record ID (Event ID) of the Event is extracted. A provisional ID, which is different from the registered record IDs within the related unit, is searched for. The searched provisional ID is set to be the record ID and is combined with a global unique ID (GUID) of the unit, thereby generating an Object ID. As a result, the Object ID for uniquely identifying the Event within a bus is speedily determined.
