Distribution Amplifier

Communications Specialties

The Pure Digital Fiberlink 8000 Series is an optical distribution amplifier (D.A.) that may be configured to transmit from one to four channels of any type of signal(s) supported by the Pure Digital Fiberlink line of products. The 8000 Series D.A. receives an optical signal from any Pure Digital Fiberlink transmitter and then digitally regenerates and relaunches it without incurring any additional degradation to the original baseband video, audio, or data signal(s). Depending on the configuration of the D.A., the signal is relaunched over one to four separate fibers, creating as many as four identical copies of the original optical signal. Each 8000 Series unit may be configured to receive signals over multimode or single-mode fiber at wavelengths of 850, 1,310, or 1,550 nm.

360 Systems

The Image Server 2000 is an MPEG-2 recorder/server. It is able to play three independent video programs at once, each with four digital-audio channels. A video input is also provided, and recordings may be made while two video programs are playing. The server's internal drives provide as much as a terabyte of program storage, giving 128 hours of video.

White Boards

Hitachi Software Engineering

The StarBoard F-60 and F-75 white boards and their associated software permit presenters to run computer applications and add freehand annotations to the displayed graphics. The StarBoard F-60 and F-75 use a combination of ultrasound and infrared technology to sense the location of pen-type devices near the surface. The surface itself is not an active component and therefore is not prone to any form of degradation or to introduce spurious contact actions into the presentation. The 60- and 75-inch display areas provide a large image on which to work and provide pinpoint accuracy in running applications and adding comments and annotations to presentations.

White Board

Smart Technologies

The mobile Rear Projection Smart Board 2000i interactive white board meets the needs of computer-using educators. Developed with educators' input, the 2000i combines the benefits of a large (66-inch/168 cm diagonal), shadowfree, touch-sensitive display with a height-adjustable design. With an easy-to-turn handle, teachers can lower the screen from teaching height to one that is easily accessible for students of all ages, including those with special needs. The 2000i includes an integrated projector with an extended-life lamp as well as free software upgrades.

Models VB443F and VB43FBD video balun transceiver/combiners are unshielded twisted-pair transmission systems. The VB43 models can send quality color or monochrome video over unshielded twisted-pair cables for distances of as much as 1,000 feet (750 feet into DVR equipment), eliminating the need for coaxial cable. In addition, they interface with four-pair Cat-3, Cat-5, Cat-5e, or Cat-6 cables to send camera power and RS422 control signals. In that way, one four-pair cable connects all of the necessary functions to and from the camera/PTZ to the head end — one pair for video, one pair for RS422, and two pairs for power.

Annotation Module

Elmo Manufacturing Corp.

The EVR-100 permits document camera users to annotate, underline, or highlight any document, photo, or flat art without damaging the original piece. It is designed for active presenters such as educators, training professionals, and medical personnel who require a simple way to annotate in longhand instead of using a mouse. The EVR-100 fits onto any of the company's full-featured analog or digital document camera. It simplifies the storage of notes, formulas, bullet points, and other aids without the need for a computer or other digital accessories.
