Patent number: 8559428Abstract: MTID of a terminal apparatus is preliminarily registered into a database of an ISP. In step S2, when a power source of the terminal apparatus is turned on first, (MTID=B) is transmitted from the terminal apparatus to a router. A transmission signal is received by the router and (HGWID=A, MTID=B) is transmitted from the router to the ISP. If (HGWID=A, MTID=B) has been registered in the database, the ISP transmits a permission message in step S5. In step S6, an IP address for a new terminal apparatus is allocated and the new terminal apparatus can participate in a homenetwork. If (HGWID=A, MTID=B) is not registered, a refusal message is sent to the router.Type: GrantFiled: January 2, 2009Date of Patent: October 15, 2013Assignee: Sony CorporationInventors: Shinya Kimura, Takahiro Sasaki, Motoki Nakade, Yoshiyuki Kunito, Akihiro Hokimoto, Makoto Oka, Shinako Matsuyama, Atsushi Shionozaki

Publication number: 20130143597Abstract: An apparatus, method and computer program storage device cooperate to provide a quality position estimation of a mobile communication device by determining a reference area. The reference area includes the position of the mobile communication device as well as a plurality of transmitters. Transmitters that are detected as being outside of the reference area are excluded from contributing to the position estimate. The reference area is centered at a standard position, which may be a previous position or a GPS based position, for example. The range of the reference area includes a component that considers the range of a transmitter, as well as a GPS error or an estimated move distance of the mobile communication device.Type: ApplicationFiled: August 24, 2011Publication date: June 6, 2013Inventors: Koshiro Mitsuya, Atsushi Shionozaki

Patent number: 8064461Abstract: Systems and methods are described for increasing data transfer efficiency between networks. The invention being particularly well suited when establishing connectivity between wireless networks, such as based on IEEE 802 standards, and traditionally wired network protocols (often referred to as internet protocols), such as TCP/IP and UDP. The invention provides formatting of network packets and then processing of network packets according to one or more optimization processes. One optimization process comprises performing partial packet retransmissions to increase network efficiency, especially in high bit error rate networks such as wireless networks. Another optimization process comprises suppressing unnecessary packet acknowledgements, therein reducing burst traffic and saving substantial overhead in lossy networks. Additional aspects of the invention provide further benefits.Type: GrantFiled: September 15, 2009Date of Patent: November 22, 2011Assignees: Sony Corporation, Sony Electronics, Inc.Inventors: Yoshifumi Nishida, Atsushi Shionozaki

Patent number: 8010862Abstract: An embodiment of the present invention includes a buffer, a selector, and an analyzer. The buffer stores at least a default stream coded by a multiple description (MD) coding and a restart stream coded by a predictive coding. The default and restart streams correspond to a media content. The selector selects a transmit frame from the default and restart streams according to a transmission status. The transmit frame is transmitted to a receiver. The analyzer provides the transmission status based on feedback information provided by the receiver.Type: GrantFiled: January 20, 2010Date of Patent: August 30, 2011Assignees: Sony Corporation, Sony Electronics Inc.Inventors: Ezra Jacques Elie Eric Setton, Atsushi Shionozaki
