Abstract:
A video collecting device (10) generates a video recorded medium (101) and a position/time recorded medium (102). A video searching device (20) creates a video database in which video data read from the video recorded medium (101) is correlated with position/time data read by a data reading section (21) by a correlating section (24) with respect to time. A video shooting trace displaying section (32) searches video data including the shooting places on a map in a map display section (28) and displays the shooting places as traces. An on-map input section (29) designates a place on the map with reference to the traces, and then a video displaying section (33) reproduces the video data on the place and its neighborhood.
Abstract:
The invention relates to a method and a device for subtitling video-camera recordings. According to the invention, subtitle information which has been inputted via a keyboard (2) is converted into video-text signals using a video-text generator (13) and inserted into the blanking intervals of the video recording. On the reproduction side, the recording can subsequently be played back with or without subtitles.
Abstract:
The invention relates to a method and a device for recording/ processing of authentic image and/or audio data. To achieve an authentic image or sound recording the entire process of converting from analogue to digital signals, the identification or the characteristics of the individual components used are received, and recorded or stored after a signature calculation. The digital data are linked with each other in a device shown by the figure in such a manner that separation of the individual processes is not possible on the device without manipulations which can subsequently be recognised. The signature also enables the order and the complete nature of all visual or audio information to be logged in a tamper-proof manner.
Abstract:
A video security system (10) capable of monitoring and recording fixed and moving targets and recording management information into a video signal such that the text can be removed from the video image produced by the video signal at playback of the recorded video signal. The VSS (10) allows a camera (70b) to switch (toggle) between two or more view positions of interest and to set the view positions into memory by pressing a single switch. The cameras (70b) are controlled to move rapidly, but accurately, between the positions within controlled parameters of speed and acceleration - including a period of substantially zero acceleration between changes in the rate of acceleration.
Abstract:
A method is provided for transmitting information having a header portion (242) and a body portion (244), the method includes the steps of providing a clock (80), generating (316) a first key base on the clock (80) and a part of the header portion (242), using the first key for encrypting the body portion (244) to generate an encrypted body portion, combining the encrypted body portion and the header portion to form a data packet (240), combining a video program and the data packet (240) to form and transmit a composite video signal (326). After encryption the encrypted body portion can be scrambled by using a scrambling key to swap the bits of the body portion. A method for receiving transmitted information having a header portion (242) and an encrypted body portion comprises the steps of providing a clock (80), generating (318) a first key based on the clock (80) and a part of the header portion (242), using the first key for decrypting the encrypted body portion to generate a decrypted body portion, combining the decrypted body portion and the header portion to form a data packet, and recording the data packet on a video cassette tape (328).
Abstract:
A video tape player monitors the selection habits of a viewer selecting from a plurality of video tapes. Each video tape contains a plurality of programs. A first type of video tape has a title information symbol contained in a predetermined interval of the tape, e.g. the vertical blanking interval, for each program on the tape. A clock provides the time of occurence of commands. A detector receives user inputted commands for controlling the movement of the video tape such as play, record, stop. The user inputted commands comprise a start play command to start moving, in a longitudinal direction, the video tape proximate to a magnetic head so that the magnetic head can detect said programs on the video tape and a stop command to stop moving the tape. A controller is coupled to said detector for commanding the motor in response to said detected user inputted commands and for reading the time of occurence of said detected user inputted commands. A first memory stores a title information symbol for each program on a second type of video tape. A second memory stores the title information symbol and the time of occurrence of said detected user inputted commands. A circuit provides the contents of the second memory to an external analyzer.
Abstract:
A full motion color digital video signal (52) is compressed, formated for transmission, recorded on compact disc media (20) and decoded at conventional video frame rates. During compression, regions of a frame are individually analyzed to select optimum fill coding methods specific to each region. Region decoding time estimates are made to optimize compression thresholds. Region descriptive codes conveying the size and locations of the regions are grouped together in a first segment of a data stream. Region fill codes conveying pixel amplitude indications for the regions are grouped together according to fill code type and placed in other segments of the data stream. The data stream segments are individually variable length coded according to their respective statistical distributions and formatted to form data frames. The number of bytes per frame is dithered by the addition of auxiliary data determined by a reverse frame sequence analysis to provide an average number selected to minimize pauses of the compact disc during playback thereby avoiding unpredictable seek mode latency periods characteristic of compact discs. A decoder includes a variable length decoder responsive to statistical information in the code stream for separately variable length decoding individual segments of the data stream. Region location data is derived from region descriptive data and applied with region fill codes to a plurality of region specific decoders selected by detection of the fill code type (e.g., relative, absolute, dyad and (DPCM) and decoded region pixels are stored in a bit map for subsequent display.
Abstract:
Systems and methods can support a data processing apparatus. The data processing apparatus can include a data processor that is associated with a data capturing device on a stationary object and/or a movable object. The data processor can receive data in a data flow from one or more data sources, wherein the data flow is configured based on a time sequence. Then, the data processor can receive a control signal, which is associated with a first timestamp, wherein the first timestamp indicates a first time. Furthermore, the data processor can determine a first data segment by applying the first timestamp on the data flow, wherein the first data segment is associated with a time period in the time sequence that includes the first time.
Abstract:
An information storage medium storing subtitle text-based information, and a method and apparatus utilizing same, process a subtitle The information storage medium includes: dialog information which contains script text information of the subtitle and information specifying an output type of the script text; and presentation information which contains style information used to convert the script text into a bitmap format through rendering. With this structure, the amount of data required for a subtitle and the amount of data that should be processed when a subtitle is output may be greatly reduced.
