    BrightEye 10 Optical/SDI to Analog/SDI Converter User Guide N S E M B L E Revision 3.0 SW v1.0.2 This user guide provides detailed information for using the BrightEye™10 Optical and SDI to Analog and SDI Converter unit. The information is organized into the following sections: •...

  • Page 2: Product Overview

    BrightEye 10 is powered by a 12 volt DC universal power supply. This power supply can accept an input voltage between 90 and 230 volts, at 50 or 60 Hertz. It uses a standard IEC line cord and can be used anywhere in the world.
  • Page 3 This application, shown in the illustration below, utilizes the full functionality of BrightEye 10 by using the converted SDI output from an optical input to feed a destination such as a video router while monitoring the signal on an RGB monitor at the same time.
  • Page 4 BrightEye 10 Optical/SDI to Analog/SDI Converter Driving an RGB Projector The ability of BrightEye 10 to accept optical inputs makes it an ideal choice for converting sources located a great distance away. One example of this would be to drive an RGB projector whose video source is located in a distant location similar to the example shown below.

  • Page 5: Rear Connectors

    BrightEye 10 REAR CONNECTORS All connections to the BrightEye 10 converter are made on the rear of the unit. Refer to the illustration below. BrightEye 10 Rear Connectors Power Connection Connect a modular power supply to the 12 volt DC power input connection on the far left of the unit.
  • Page 6 BrightEye 10 Optical/SDI to Analog/SDI Converter Input/Output BNCS There are five rear BNC connectors used as inputs and outputs as follows: SDI In This BNC input accepts a SMPTE 259M serial digital component signal, 525 or 625 line standard. SDI Out The Serial Digital Component signal from the reclocking circuitry is presented on this connector.

  • Page 7: Operation

    BrightEye 10 OPERATION Control and operation of the BrightEye 10 converter is performed from the front panel or with the BrightEye Control application. Some control settings are only available with BrightEye PC or Mac. These parameters NOTE: cannot be monitored or controlled with the front panel.

  • Page 8: Adjusting Parameters From The Front Panel

    BrightEye 10 Optical/SDI to Analog/SDI Converter ADJUSTING PARAMETERS FROM THE FRONT PANEL Use the Mode, Right Arrow, and Left Arrow buttons to select and adjust parameters from the front panel. Pressing the Mode button activates the front panel for editing and tabs between each section of editable parameters.

  • Page 9: Using The Brighteye Control Application

    USING THE BRIGHTEYE CONTROL APPLICATION The BrightEye PC and BrightEye Mac applications included on CD-ROM are designed to allow you to configure and control the BrightEye 10 from a personal computer. Installation and instructions for using this software application are given in the PDF manual on disk.
  • Page 10 BrightEye 10 Optical/SDI to Analog/SDI Converter Output Menu • Output – select the type of output signal from the unit from the Output pulldown as Composite, Beta, SMPTE, or RGB. • Gain – adjusts the gain of the analog video signals in the Digital-to-Analog converter and encoder circuitry of the converter.

    BrightEye 10 Optical/SDI to Analog/SDI Converter BRIGHTEYE POWER SUPPLY INFORMATION Below is a list of power supplies and optional items that may have come with your BrightEye: BEPS BrightEye Individual Power Supply. BEPS6 Spider Power Supply. This powers 6 single high BrightEyes or 3 double high BrightEyes (BrightEye 90 family).
  • Page 15 BrightEye 10 GLOSSARY This is a brief glossary of commonly used terms associated with this product. AES/EBU The digital audio standard defined as a joint effort of the Audio Engineering Society and the European Broadcast Union. AES/EBU or AES3 describes a serial bitstream that carries two audio channels, thus an AES stream is a stereo pair.
  • Page 16 BrightEye 10 Optical/SDI to Analog/SDI Converter Chroma The color or chroma content of a signal, consisting of the hue and saturation of the image. See also Color Difference. Component In a component video system, the totality of the image is carried by three separate but related components.
  • Page 17 BrightEye 10 dBFS In Digital Audio systems, the largest numerical value that can be represented is referred to as Full Scale. No values or audio levels greater than FS can be repro- duced because they would be clipped. The nominal operating point (roughly corre- sponding to 0 VU) must be set below FS in order to have headroom for audio peaks.
  • Page 18 BrightEye 10 Optical/SDI to Analog/SDI Converter The International Electrotechnical Commission provides a wide range of worldwide standards. They have provided standardization of the AC power con- nection to products by means of an IEC line cord. The connection point uses three flat contact blades in a triangular arrangement, set in a rectangular connector.
  • Page 19 BrightEye 10 Multi-mode Multi-mode fibers have a larger diameter core (either 50 or 62.5 microns), and a correspondingly larger aperture. It is much easier to couple light energy into a multi-mode fiber, but internal reflections will cause multiple “modes” of the signal to propagate down the fiber.
  • Page 20 BrightEye 10 Optical/SDI to Analog/SDI Converter Return Loss An idealized input or output circuit will exactly match its desired impedance (generally 75 ohms) as a purely resistive element, with no reactive (capacitive or inductive elements). In the real world we can only approach the ideal. So our real inputs and outputs will have some capacitance and inductance.
  • Page 21 BrightEye 10 A Time Base Corrector is a system to reduce the Time Base Error in a signal to acceptable levels. It accomplishes this by using a FIFO (First In, First Out) memory. The incoming video is written into the memory using its own jittery timing.
