Patent number: 7657630Abstract: 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.Type: GrantFiled: September 10, 2004Date of Patent: February 2, 2010Assignees: Sony Corporation, Information Broadcasting Laboratories, Inc.Inventors: Yoshihisa Gonno, Fumihiko Nishio, Kazuo Haraoka, Yasuaki Yamagishi

Patent number: 7627881Abstract: A transmitting system for transmitting contents data, meta data, and meta data schema. A meta data schema that represents the structure of meta data of contents data is stored in a meta data schema storing portion. A contents segmenting portion generates segmentation data for selecting a particular segment from successive contents data supplied from a contents storing portion and supplies the generated segmentation data to a meta data combining portion. The meta data combining portion correlates meta data with corresponding segmentation data in a format corresponding to the structure of the meta data schema, combines the meta data with the segmentation data, and outputs the combined data. The meta data schema, meta data with segmentation data, and contents data are converted in a transmission format.Type: GrantFiled: January 28, 2000Date of Patent: December 1, 2009Assignees: Sony Corporation, Information Broadcasting Laboratories, Inc.Inventors: Yoshihisa Gonno, Fumihiko Nishio, Kazuo Haraoka, Kazuhiko Takabayashi, Yasuaki Yamagishi
