  • Page 2: Product Overview

    BrightEye 75 HD/SD Analog to Digital Converter and Analog Audio Embedder PRODUCT OVERVIEW BrightEye 75 converts standard definition analog component or composite video, or high definition analog component video to SDI with simultaneous conversion of two channels of audio and embedding. A TBC/Frame Sync is a standard feature and allows the BrightEye to work with any type of video input.

  • Page 4 BrightEye 75 HD/SD Analog to Digital Converter and Analog Audio Embedder APPLICATIONS The BrightEye 75 is well-suited to applications using HD Cameras or other devices with analog I/O. The built-in TBC/Frame Synchronizer allows you to feed asynchronous or noisy signals to the BrightEye 75. These are then digitized and time-base corrected by noise-tolerant tracking circuitry.

  • Page 5: Rear Connectors

    BrightEye 75 REAR CONNECTORS All connections to the BrightEye 75 converter are made on the rear of the unit. Refer to the illustration below. BrightEye 75 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 75 HD/SD Analog to Digital Converter and Analog Audio Embedder Unbalanced Audio to a RCA Phono Connection – to connect the BrightEye 75 audio input to a consumer audio connector such as an RCA phono jack, connect the pins as follows: •...

  • Page 7: Operation

    BrightEye 75 OPERATION Control and operation of the BrightEye 75 unit is performed from the front panel or remotely from a networked PC with the BrightEye Control application. Some control settings are only available with BrightEye PC or Mac. These parameters NOTE cannot be monitored or controlled from the front panel.

  • Page 8: Adjusting Parameters From The Front Panel

    BrightEye 75 HD/SD Analog to Digital Converter and Analog Audio Embedder Illuminates green when gain is set to unity, red when set to other than unity, or yellow when gain exceeds 0 VU (-20dBFS). Pwr (Power) Illuminates green when power is applied to the 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.
  • Page 9 BrightEye 75 Vid Gain This control adjusts the gain of the analog video signals of the converter. The right arrow increases the gain; the left arrow decreases it. The Vid Gain indicator illuminates green when the gain is set to its nominal or unity setting. Setting Vid Gain to unity ensures correct analog output levels from an analog input source that is at proper level itself.

  • Page 10: Using The Brighteye Control Application

    BrightEye 75 HD/SD Analog to Digital Converter and Analog Audio Embedder 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 75 from a personal computer.
  • Page 11 BrightEye 75 Proc Menu Use the Proc Menu to adjust the parameters of the analog video input signal. The Proc menu provides the following video adjustments: • Gain – adjust the overall gain of the signal from 0 to 150%. •...
  • Page 12 BrightEye 75 HD/SD Analog to Digital Converter and Analog Audio Embedder Mixer Menu Use the Mixer Menu to adjust the parameters of the embedded audio input signal. • Output 1 – provides peak/VU status for output channel 1. The Peak/VU indicator illuminates red when the audio level exceeds the headroom level set with the Peak Indicator control in the Config menu.
  • Page 13 BrightEye 75 Timing Menu Use the Timing Menu to set the parameters of the TBC and Frame Sync functions. 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 is synchronous and locked to the external reference.
  • Page 14 BrightEye 75 HD/SD Analog to Digital Converter and Analog Audio Embedder Config Menu Use the Config menu to set the following output conditions for the output signal: • Signal Mute – select the condition for muting the output signal to No Muting, Mute On Noise, or Freeze on Noise.
  • Page 15 BrightEye 75 Trim Menu The Trim menu provides an advanced level of adjustment to match your BE75 to a particular source if needed. Use the Trim menu to fine tune the color parameters of the output signal up or down, positive or negative. The values shown below are typical, though each BE75 may vary.

  • Page 20 BrightEye 75 HD/SD Analog to Digital Converter and Analog Audio Embedder 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 21 BrightEye 75 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 22 BrightEye 75 HD/SD Analog to Digital Converter and Analog Audio Embedder 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.
  • Page 23 BrightEye 75 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 24 BrightEye 75 HD/SD Analog to Digital Converter and Analog Audio Embedder Multimode Multimode 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 multimode fiber, but internal reflections will cause multiple “modes” of the signal to propagate down the fiber.
  • Page 25 BrightEye 75 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 26 BrightEye 75 HD/SD Analog to Digital Converter and Analog Audio Embedder 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.
