First Claim
1. A contents providing device for providing a contents signal to a plurality of contents receiving devices, the contents providing device comprising:
- a receiving unit which receives request signals transmitted from the plurality of contents receiving devices;
a totaling unit which totals the request signals received by the receiving unit;
a resource allocation unit which allocates a resource and adjusts a transmission schedule for providing the contents signal on the basis of the result of totaling by the totaling unit; and
a contents providing unit which provides the contents signal to the plurality of contents receiving devices on the basis of the resource allocated by the resource allocation unit;
an event signal generation unit which generates an event signal indicating the provision of the contents signal; and
an event signal transmission unit which transmits the event signal to the plurality of contents receiving devices,wherein,the contents providing device further comprises an update signal generating unit which generates an update signal for updating, in the contents receiving device, the same contents signal as an updated contents signal registered in the database when it is updated,the event signal generation unit generates a signal indicating the provision of the update signal as the event signal,the resource allocation unit allocates a resource for providing the update signal as the contents signal,the contents signal providing unit provides the update signal in the contents signal.

Abstract
At a server 2, a subject for updating an object registered in a database 3 and an event for obtaining the subject are generated, while a request for the subject from a receiving terminal 5 is received and totaled so that a resource necessary for providing the subject is allocated on the basis of the result of totaling. Then, the event is transmitted and the subject is provided on the basis of the resource allocated thereto. At the receiving terminal 5, the event is received and the necessity of the subject to be obtained on the basis of the event is evaluated so that request data requesting the subject is transmitted to the server 2 on the basis of the result of evaluation. Then, the subject provided by the server 2 in response to the request data is obtained on the basis of the event.
