Patent number: 7099564Abstract: An image recording and reproducing apparatus for recording and reproducing a multiple picture signal obtained by multiplexing picture signals from a plurality of cameras via a frame switcher, the image recording and reproducing apparatus performing high-accuracy fast-forwarding of a prerecorded image from a specific camera and allowing easy retrieval of a target image. The image recording and reproducing apparatus has a skip reproduction feature for alternating skipping of n frames and continuous reproduction of m frames. m is set to a number related to the frame switching pattern. In case n=4 and m=3, four frames are skipped after reproduction of Frame A1. Then Frames C6, A7, B8 are continuously reproduced. Thus, the images displayed on the monitor are A1, A7, and A13.Type: GrantFiled: July 26, 2001Date of Patent: August 29, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Mamoru Higashimura, Kazuhisa Tsuzuki, Motohiro Misawa, Megumi Umezawa, Ichiro Ogawa, Manabu Nakamura

Patent number: 6838974Abstract: Plural security units are coupled to plural control units through a communication line including transmission and response lines. Each control unit detects data collision on the transmission line to avoid the data collision. Re-transmission interval is independently assigned to each control unit. If the command to or from a security unit in charge of this control unit is received, the control unit rewrites the conditional data of the security unit in accordance with the detected command. The control (security) unit further includes a transmission (response) line monitoring portion, so that bi-directional communication is provided in addition of the response (transmission) line monitoring portion. Address data is classified to provide all unit communication, a group communication, and independent communications.Type: GrantFiled: December 27, 2000Date of Patent: January 4, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Kazuhisa Tsuzuki, Motohiro Misawa, Tooru Toyoda

Patent number: 6747554Abstract: In a network surveillance unit, a video input unit inputs image information output from a video output device such as a camera or a switcher. A coded image storage unit codes and accumulates the image information. An alarm management unit detects the presence or absence of alarm generation from an alarm generating device, and stores the alarm information. A communication unit receives a request from a display terminal through a network, and transmits the coded image accumulated in the coded image storage unit or the alarm information accumulated in the alarm management unit according to the request.Type: GrantFiled: January 20, 2000Date of Patent: June 8, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Mamoru Higashimura, Manabu Nakamura, Junichi Hamada, Motohiro Misawa

Patent number: 6559765Abstract: An integrated security system includes a plurality of security devices each issuing an alarm signal. A plurality of control units are associated to control the security devices via a communication line. Each security device comprises an alarm storing section for storing alarm signals received from individual security devices as alarm information. An alarm transmitting section transmits the alarm information to all of the control units via the communication line. The alarm information stored in the alarm storing section during a predetermined storage time are transmitted at a time as an alarm notification command to the control units.Type: GrantFiled: December 28, 2000Date of Patent: May 6, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Kazuhisa Tsuzuki, Motohiro Misawa, Tooru Toyoda

Patent number: 5365264Abstract: A bi-directional video signal transmission system is equipped with transmission lines having coupled upsteam and downstream segments. With the entire band of a RF signal being taken as a modulation frequency band, an image signal modulated to a frequency band and RF-multiplexed in the upstream segment is introduced into the downstream segment at the modulated frequency and is then branched to demodulate the same frequency band, thereby obtain one video signal transmission channel. In response to a request by a subscriber, a channel management section assigns and releases the transmission channels and further outputs a control command whereby a transceiver control section performs switching-control of the transmission frequencies to transceiver units.Type: GrantFiled: November 29, 1991Date of Patent: November 15, 1994Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Akino Inoue, Motohiro Misawa, Kazuaki Yamaguchi, Etsumi Kanaya
