Publication number: 20040210949Abstract: A data reception and playback apparatus that enables reception of data to be played back next to be performed to the fullest extent possible without degrading the playback quality of data being played back, allowing a plurality of data to be played back seamlessly. In this apparatus, a schedule control section decides the pre-read schedule (pre-read amount and pre-read time interval) of media data to be played back next based on a receive buffer decrease speed input from a receive buffer observation processing section, and outputs a data acquisition request command to a data request processing section in accordance with this pre-read schedule. Data request processing section converts the data acquisition request command for AV2 data input from a schedule control section to a data request signal, outputs this signal to a communication processing section, and executes AV2 data small-amount pre-read processing for a server.Type: ApplicationFiled: April 6, 2004Publication date: October 21, 2004Applicant: Matsushita Electric Industrial Co., Ltd.Inventors: Masataka Sugiura, Mitsuhiro Suzuki

Publication number: 20040103011Abstract: An insurance system that guarantees re-distribution of electronically distributed authorized data. The insurance system is constructed in such a way that a right to receive re-distribution is generated contingent upon taking out an insurance policy, and can thereby implement an insurance system capable of smoothly carrying out re-distribution of contents electronically distributed through a network. Furthermore, the insurance system is constructed in such a way as to receive re-distribution through the insurance service server, which allows the insurance service server to control re-distribution independently and prevents illegal re-distributions as a consequence.Type: ApplicationFiled: December 2, 2003Publication date: May 27, 2004Inventors: Kouji Hatano, Masataka Sugiura, Yoshihiro Tsukamoto, Satoshi Terasaki

Patent number: 6362783Abstract: A method of detecting a position of a radio mobile station in radiocommunications, which is capable of accurately and simply finding the position of the mobile station. At a measuring point the mobile station measures the reception radio strength levels from a plurality of base stations and conveys the measurement results through the base station to a control station. The control station learns, through a neural network, the correlation between the reception radio strength levels and the position of the mobile station on the basis of the measurement results at a plurality of measuring points and the positions of the measuring points. Subsequently, when the mobile station communicates to the control station the reception radio strength levels measured at an arbitrary point, the control station estimates the position of the mobile station, causing those measurement results, on the basis of the correlation obtained through the learning.Type: GrantFiled: October 3, 2000Date of Patent: March 26, 2002Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masataka Sugiura, Hiroyoshi Ishibashi, Etsumi Kanaya, Toru Kubo, Kazuaki Yamaguchi, Natsuki Oka
