Publication number: 20090239567Abstract: In conventional services for communicating various media, there are limits to the number of users, the number of group lists, and the like that can be handled by servers provided by communication providers. A service system includes a server provider network 4 in addition to communication provider networks 1 to 3, and the communication provider networks 1 to 3 and the server provider network 4 are configured to be able to communicate with a PoC domain server 2 through the Internet 1. A server provider network (4) 3D having a PoC server 3D-1 and a GL server 3D-2 is also added. The user can receive services of PoC and the like from a terminal device 6 by automatically searching another server such as a server 3B-1 when users beyond the capability of a server 3A-1 simultaneously try to communicate.Type: ApplicationFiled: October 30, 2006Publication date: September 24, 2009Inventor: Nobuyuki Ema

Patent number: 7181125Abstract: A device which is capable of storing moving picture data received from each terminal and providing each terminal with video information to be reproducible by rapidly forwarding or reversing at any desired speed independent of usable terminals. A video storage type communication device 30 with a receiving portion 35 and a transmitting portion 38 transmits and receives video data over a communication network 10 to and from each terminal 1–n. A coded video data received from terminals 1–n is stored as it is in a first storage portion 32 and, at the same time, the data converted into specially reproducible video information is stored in the second storage portion 33. At the time of reproducing, the reproduction control portion 35 controls the reproduction selector switch 36 to obtain the video data from the first storage portion 32 or the second storage portion 33, changing the reproduction mode from ordinary to the rapid forwarding/reversing and vice versa.Type: GrantFiled: January 9, 2002Date of Patent: February 20, 2007Assignees: Sharp K.K., Nippon Telegraph & Telephon CorporationInventors: Hirotaka Nakano, Osamu Nakamura, Youji Kanada, Tsuneko Kura, Takashi Oshima, Tadashi Uchiumi, Keiichi Hibi, Jiro Nakabayashi, Tsuneaki Iwano, Nobuyuki Ema

Patent number: 6275532Abstract: In a video-coding and video-decoding device, motion-compensated interframe prediction is achieved by determining motion vectors of respective pixels according to representative motion vectors with weighting, and determining accurate motion vectors between video frames, dividing each frame into areas optimal to an objective figure, size and location and performing effective encoding and decoding of the motion vectors. According to the invention a motion-compensated interframe predicting portion generates a predicted video-frame by varying codable area according to a reference video-frame received from a frame memory portion and an input video frame and obtains side-information. A motion vector searching portion searches a motion vector.Type: GrantFiled: August 29, 1996Date of Patent: August 14, 2001Assignee: Sharp Kabushiki KaishaInventors: Keiichi Hibi, Nobuyuki Ema

A video storage type communication device 30 with a receiving portion 35 and a transmitting portion 38 transmits and receives video data over a communication network 10 to and from each terminal l-n. A coded video data received from terminals l-n is stored as it is in a first storage portion 32 and, at the same time, the data converted into specially reproducible video information is stored in the second storage portion 33. At the time of reproducing, the reproduction control portion 35 controls the reproduction selector switch 36 to obtain the video data from the first storage portion 32 or the second storage portion 33, changing the reproduction mode from ordinary to the rapid forwarding/reversing and vice versa.Type: GrantFiled: October 1, 1997Date of Patent: June 20, 2000Assignees: Sharp K.K., Nippon Telegraph & Telephon CorporationInventors: Tadashi Uchimi, Keiichi Hibi, Jiro Nakabayashi, Tsuneaki Iwano, Nobuyuki Ema, Hirotaka Nakano, Osamu Hakamura, Youji Kanada, Tsuneko Kura, Takashi Oshima

Patent number: 5742729Abstract: A video storage type communication device stores video data received from a terminal and reproduces required video information by rapid forwarding or reversing at any desired frame rate at the terminal independent of the terminal specification. A video storage type communication device includes a transmitting portion for transmitting video data and a receiving portion for receiving video data over a communication line. A video storage portion stores received video data. A communication control portion carries out video communication by controlling the above-mentioned portions. A refresh image detecting portion judges, from the received video data, whether the received video data is a refresh image. A storage control portion adds inter-frame or intra-frame prediction coded information to the received video data in accordance with the determination by the refresh image detecting portion and stores the received video data in the video storage portion.Type: GrantFiled: March 12, 1996Date of Patent: April 21, 1998Assignees: Sharp Kabushiki Kaisha, Nippon Telegraph and Telepone CorporationInventors: Nobuyuki Ema, Keiichi Hibi, Jiro Nakabayashi, Tsuneaki Iwano, Osamu Nakamura, Youji Kanada, Tsuneko Kura, Takashi Oshima
