Patent number: 7796512Abstract: A session mobility for moving a session held between a switching source device and a communication counterpart to a switching destination device other than the switching source device. The switching source device transmits media data relating to a session by multicast or broadcast prior to device switching. The switching destination candidate device receives the transmitted media data, and thereby switching destination determined device, in replace of the switching source device, outputs media data. Thus, a switching time from a switching source device to a switching destination device can be made fast such that a user cannot perceive it.Type: GrantFiled: March 13, 2006Date of Patent: September 14, 2010Assignee: Panasonic CorporationInventors: Daisaku Komiya, Sachiko Takeshita, Mingqiang Xu, Kentaro Takei, Maki Amishima

Patent number: 7539759Abstract: A protocol for extending session endpoints in an ad-hoc network environment first performs device discovery to determine local devices within its coverage area and the capability of those devices. These local devices then exchange session descriptions with the endpoint device. If the current session may be supported by one of the local devices, the endpoint device, responsive to a command from an user, transfers the session endpoint to the local device and the endpoint device acts as a proxy for the local device in the session. Optionally, if the local device has a path to the correspondent node that is independent of the path through the endpoint device, it establishes the session along this path and then signal the endpoint node to terminate its session.Type: GrantFiled: April 15, 2003Date of Patent: May 26, 2009Assignee: Panasonic CorporationInventors: Sathya Narayanan, Daisaku Komiya, Rajesh Khandelwal

Publication number: 20080205507Abstract: When a switching target device receives a media output indication from a sender device, a switch (401) connects with contact B, which causes all image data stored in an extended media buffer (402) to be inputted in a decoder (201), starting from the first frame (which is an I-frame) of the image data. The decoder (201) decodes the image data, starting from the I-frame, and stores a reconstructed image in a reconstructed-image buffer (202). A reconstructed image required for decoding video picture data outputted from a media buffer (2108) is held in the reconstructed-image buffer (202). Thus, when device switching occurs, the decoder (201) can immediately start decoding regardless of whether video picture data inputted from the media buffer (2108) is an intraframe.Type: ApplicationFiled: February 8, 2006Publication date: August 28, 2008Applicant: MITSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventors: Daisaku Komiya, Yoshimasa Honda, Sachiko Takeshita
