Abstract: 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.

Abstract: Monitor camera units, a data storing unit, a control server, and a monitor display are coupled by a network. The monitor camera unit includes a motion detector for detecting motion from video data, a microphone, a traffic monitor, a memory for storing the video data, and a sensor signal input circuit. The traffic monitor monitors the traffic of the network. If the traffic is high, only necessary data or sound data is transmitted. The memory stores the video data in response to the motion detector and a thinning circuit thins the video data from the memory in response to a sensor signal. The control server receives the alarm data from the monitor camera and further receives the alarm type data, time data, position data of a pivoting unit for pivoting the camera unit and transmits the data to the display terminal. In the presence of a loud sound, alarm data is also generated but it is not sent if a switch is OFF. The control server includes a data base storing set of alarm data.

Abstract: When a video input (image data) sequentially fetched from a monitor camera is to be stored in data storage means, frame rate calculating means calculates a frame rate for storage of the image data by using a picture recording time mode, a residual capacity of the data storage means, the presence of generation of an alarm signal and a value of a picture quality parameter for data compression. The frame rate calculating means thins a video signal which does not correspond to the frame rate so as not to be stored in the data storage means. Consequently, image data for a predetermined time are stored in the data storage means.

Abstract: 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.

Abstract: The identification information input apparatus comprises a rotary encoder group for giving the user a click feel per unit rotation and generating an electric signal, and inputting arbitrary alphanumeric characters forming alphanumeric characters assigned in proportion to rotation angle via rotating operation, a pushbutton switch group for confirming alphanumeric characters input via the dial unit, password conversion unit for converting the electric signal generated by the dial unit to the alphanumeric characters based on a conversion table, and password authentication unit for authenticating the converted alphanumeric characters by checking whether the alphanumeric characters converted by the conversion unit are alphanumeric characters constituting the password.

Abstract: A multimedia information distributing system for accumulating multimedia title data to supply title data in accordance with a demand from a client. The multimedia information distributing system is composed of clients and a server which are in communicable relation to each other. Each client includes a material and scenario storage information converting section having a conversion rule between an environment depending upon the client and an internal environment of a title server to convert material position information into a format agreeing with each environment. The client transmits material storage information and a title comprising materials and scenario to the server. The server registers the transmitted title through the use of the material storage information made in advance in the client to agree with the server environment.
