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

Publication number: 20020154558Abstract: The progress status of the download later than the actual progress status is displayed on a display unit of a terminal in a period of downloading encrypted music data MD1′.[92% completed] is displayed in a display screen Z2 even though the download of the encrypted music data MD1′ is completed in time t3. And, the billing request Creq is transmitted to a distribution and billing server in time t5, and a display screen Z3, showing the download is completed, is displayed on the display unit after the terminal receives the billing request C req.Type: ApplicationFiled: May 2, 2002Publication date: October 24, 2002Inventors: Yasuhiro Urata, Hidekazu Li, Kuniaki Naoi, Youji Kanada, Toshihiro Sugano, Kenichi Suimon, Toshiyuki Ishizuka, Nobuyuki Takahashi

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: 5796436Abstract: If received coded video-data includes data with an error unable to be decoded or data disagreeing with ITU-T recommendation H.261 (e.g., the number of bits per frame exceeds the limit defined by the recommendation), it must be stored with due countermeasures taken against error and inadaptable data, which allows the stored data to be effectively reproduced. Received coded video-data is decoded by a transmission-line decoding portion and divided into frames by a data dividing portion. Thereafter it is decoded by an information-source decoding portion and then intraframely encoded by a intraframe coding portion. According to a signal from a bit-counting portion showing that the number of bits in one frame of coded video-data exceeds the limit defined by ITU-T recommendation H.Type: GrantFiled: September 13, 1996Date of Patent: August 18, 1998Assignees: Sharp Kabushiki Kaisha, Nippon Telegraph & Telephone CorporationInventors: Masahiro Shioi, Takeshi Makiyama, Keiichi Hibi, Jiro Nakabayashi, Tsuneaki Iwano, Osamu Nakamura, 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
