Abstract: The invention relates to a system and method of communication between optical transceivers in an optical WDM network, wherein a broad-band modulation of optical signals in a primary frequency band is utilized for transmitting primary high-speed data, while a plurality of relatively low-frequency in-band subcarriers is used to modulate the optical signals to transmit secondary data between network nodes, wherein the plurality of low-frequency subcarriers lie at least in part within the primary frequency band.

Abstract: Methods, systems and software are disclosed for automated Measurement of Video Quality parameters. The system includes a static Test Pattern provided either in form of a Test Pattern File, converted via a standard playout device (test source) into analog or digital test signal and supplied to the input of a System Under Test, or in form of a Reflectance Chart installed before the front-end device of the System Under Test, such as TV camera. The system also includes a video capture device connected to the back-end device of the System Under Test, e.g. to the output of system decoder/player. A Video Quality Analyzer processes the captured video data and generates a detailed Analysis Report.

Abstract: A CCD video camera is coupled to a host system. The CCD video camera captures image data representing elements in its field of view. The video camera does not include a digital signal processing circuit for processing the raw video data into the appropriate video format. The raw video data is processed and converted into the appropriate video format for display by the host computer system after it is received from the video camera. Necessary gain adjustments and control signals are calculated within the host computer and provided to the video camera or used during the digital signal processing of the video data to adjust the parameters of the data before the video images are displayed. A histogram is generated in order to continually monitor and adjust the exposure and gain of the system and thereby appropriately change the necessary control signals for optimal performance.

Abstract: A disk-assisted system for editing video tapes. Source material from video tapes is logged onto random access storage such as a hard disk drive using of a Macintosh-based computer system. At any one time, only a small portion of the tape material is stored as video frames on the computer disk. By software control, material is cached back and forth between the computer disk and the video tape. Thus editing is accomplished and an edit decision list constructed for compilation of the final video production. This provides the advantage of fast access time for editing of the material which is on the disk while allowing actual physical editing at the end of the project of the actual video tape material. The processes of logging the material onto the disk and editing the final tape are performed automatically.

Abstract: A harness release device for towing a water skier by a harness worn by the skier. The device having a frame and a cylindrical handle with two ends both of which being rotatably attached to and supported by the frame. The handle is freely rotatable about its longitudinal axis. A harness line, having a first end and a second end, is fixedly attached to said frame at the first end. The second end of the harness line is releasably connected to the handle. The releasable connection is formed by winding the second end of the harness line around the handle by rotating the handle in a first direction. The harness engages the harness line whereby if the skier lets go of the handle, the handle spins thus releasing the harness line from the handle and the harness.

Abstract: A computer-based video editing system provides software controlled wipes between scenes. These wipes may be the conventional horizontal, vertical, or clock type wipes used in video to transition from one scene to the next. Instead of being generated by conventional digital wave form generators, the wipes are generated as a bit map in computer memory, thus allowing the editor to design his own wipes as desired. The wipes are generated by comparators which have as their inputs line-by-line video data and computer controlled threshold data so as to control a video switcher to select between scenes as determined by the wipe pattern.
