  • Page 2: Product Overview

    It also disembeds audio from the SDI input and converts it to four analog audio outputs. The BrightEye 16 has an SDI video and a reference input. The input signal is converted to analog composite and synchronized (genlocked) to the reference signal.
  • Page 3 D-to-A Conversion to Analog Destination One application, shown in the illustration below, utilizes the full functionality of BrightEye 16 by using the converted SDI input from a video server to feed an analog VTR, all timed to the same house reference.

  • Page 4: Rear Connectors

    BrightEye 16 D-to-A Converter TBC/FS and Disembedder REAR CONNECTORS All connections to the BrightEye 16 converter are made on the rear of the unit. Refer to the illustration below. BrightEye 16 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 5: Operation

    OPERATION Control and operation of the BrightEye 16 converter is performed from the front panel or with the BrightEye Control application. Some control settings are only available with BrightEye PC or BrightEye Mac. These NOTE parameters cannot be monitored or controlled with the front panel.

  • Page 6: Adjusting Parameters From The Front Panel

    BrightEye 16 D-to-A Converter TBC/FS and Disembedder The Gain indicator illuminates red when the gain level has been adjusted off from unity by the user. The 0 VU point corresponds in the digital domain to the digital reference level (-18 or -20 dBFS) and in the analog domain to the analog reference level (-10 or +4 dBu).
  • Page 7 Timing The timing function operates in one of three modes: 1. When the Frame Sync control is turned On and a proper reference signal is connected to the Ref In BNC, the video output of the unit will be syn- chronous and locked to the external reference.

  • Page 8: 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 16 from a personal computer. Installation and instructions for using this software application are given in the PDF manual on disk.
  • Page 9 Proc Menu • Gain – adjust the overall gain of the signal from 50 to 150%. • Chroma – adjust the chroma gain of the signal from 50 to 150%. • Pedestal – adjust the pedestal level of the signal +/- 5 IRE. •...
  • Page 10 BrightEye 16 D-to-A Converter TBC/FS and Disembedder Audio Mixer Menu • Outputs 1-4 – provide peak/VU status, with the same methodology as the front panel VU indicators, but on a per channel basis, rather than per channel pair. Peak/VU indicators illuminate red when the audio level on that channel exceeds the headroom level set by the user with the Peak Indicator control.
  • Page 11 Timing Menu Use the timing controls below when the Frame Sync function is On: • Ver Time – adjust the vertical timing of the signal in lines in reference to the Ref In signal. • Hor Time – adjust the horizontal timing of the signal in clocks in reference to the Ref In signal.
  • Page 12 BrightEye 16 D-to-A Converter TBC/FS and Disembedder Output Menu Use the Output menu to set the following output conditions for the module: • V Blanking – set the vertical blanking to Narrow (NTSC: lines 1-9, PAL: lines 1-6) or Wide (NTSC: lines 1-20, PAL: lines 1-22).
  • Page 13 Aud Config Menu Use the Aud Config menu to set the following output conditions for each audio group: • Dig Ref Level – selects the digital reference output level. This pulldown lets you choose between: -20 dBFS or -18 dBFS. •...

    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 18 BrightEye 16 D-to-A Converter TBC/FS and Disembedder 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 19 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. This method provides the best image fidelity with the fewest artifacts, but it requires three independent transmission paths (cables).
  • Page 20 BrightEye 16 D-to-A Converter TBC/FS and Disembedder 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 21 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. The IEC specification does not dictate line voltage or frequency.
  • Page 22 BrightEye 16 D-to-A Converter TBC/FS and Disembedder 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 23 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 24 BrightEye 16 D-to-A Converter TBC/FS and Disembedder 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.
