BrightEye 54 TM Sync Generator and Test Signal Generator User Guide ENSEMBLE D E S I G N S Revision 4.1 SW v1.0.3 This user guide provides detailed information for using the BrightEye 54 Sync Generator and Test Signal Generator unit.
BrightEye 54 Sync Generator and Test Signal Generator PRODUCT OVERVIEW BrightEye 54 is a master sync generator and test signal generator that is perfect as a master reference generator for remote trucks, desktop, and fly packs. It is a stable timing source, operating from an internal precision standard that meets full broadcast specifications.
BrightEye 54 TM The digital Tone Generator is also locked to the master clock, so the 48 KHz AES output will be synchronous to the video outputs. In NTSC there are exactly 8008 audio samples in every 5 video frames. There will be exactly 1920 audio samples in every PAL video frame. The Tone Generator can be configured for a 1.0 KHz continuous tone, or an interrupted tone which is coordinated with the Cyclops moving element.

BrightEye 54 TM APPLICATIONS BrightEye 54’s small size and complete feature set make it a versatile sync and test signal generator. Some examples of possible BrightEye 54 applications are given below. Desktop Application BrightEye 54 is convenient for desktop and non-linear editing applications since it can provide reference for all types of VTRs and provides test signals as well.
BrightEye 54 Sync Generator and Test Signal Generator Satellite or ENG Feeds Use BrightEye 54 in conjunction with the BrightEye 20 embedder and BrightEye 1 converter and frame sync to manage satellite feeds and transmission signals. Analog or AES Audio µW Rcvr Analog Video BrightEye 1 ADC/FS BrightEye 54 SPG/TSG BrightEye 20 Embedder SDI/Embed AES & Analog Audio SDI/Embed Test Signals REAR CONNECTORS All connections to the BrightEye 54 converter are made on the rear of the unit.
BrightEye 54 TM Power Connection Connect a modular power supply to the 12 volt DC power input connection on the far left of the unit. Use the locking ring to secure it. USB Connector The USB connector is used to provide more comprehensive control, diagnostics, and upgrades to the unit from a PC or Mac. Use the BrightEye Control application included on CD-ROM to make adjustments as described in the OPERATION section of this user guide.
BrightEye 54 Sync Generator and Test Signal Generator OPERATION Control and operation of the BrightEye 54 is performed from the front panel or with the BrightEye Control application. NOTE: Some control settings are only available with BrightEye PC or Mac. These parameters cannot be monitored or controlled with the front panel. Front Panel Controls and Indicators The front panel, as shown in the figure below, provides status indicators and control over video and audio output.
BrightEye 54 TM 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. Pressing the Right Arrow or Left Arrow advances the selection within a given section of parameters, or increases (Right Arrow) or decreases (Left Arrow) the value of a selected parameter.
BrightEye 54 Sync Generator and Test Signal Generator Slate This control allows the identification slate on the test signal output to be turned on and off. The content of the slate can be configured in the Config menu in the BrightEye Control application. Tone This control toggles the analog audio tone on and off. This applies to the analog audio out, the AES out, and the embedded tone on the SDI out. Advanced configuration of digital and analog audio reference levels is available in the Config menu.
BrightEye 54 TM 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 54 from a personal computer. Installation and instructions for using this software application are given in the PDF manual on disk.
BrightEye 54 Sync Generator and Test Signal Generator Config Menu Use the Config menu shown below to set the following parameters: • Standard – select the output standard for SDI and composite video. This pulldown lets you chose between: NTSC (525) and PAL (625). • HD Standard – select the HD Tri Level Sync standard. This pulldown lets you choose between: 1080i, 720p, 1080p, or 1080sF. • Setup – turn Setup On or Off for 525 60Hz signals.
BrightEye 54 TM ADJUSTMENTS Frequency Adjustment The BrightEye 54 contains a precision timing source that is calibrated at the factory to meet full specifications for timing precision. However, because clock crystals shift frequency as they age, it may be necessary to adjust the frequency of the internal source. This adjustment should not be necessary until after several years of use.

BrightEye 54 Sync Generator and Test Signal Generator 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. The AES/EBU standard covers a wide range of sample rates and quantizations (bit depths.
BrightEye 54 TM 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). The commonly used component formats are Luminance and Color Difference (Y/Pr/Pb), and RGB.
BrightEye 54 Sync Generator and Test Signal Generator 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 reproduced because they would be clipped. The nominal operating point (roughly corresponding to 0 VU) must be set below FS in order to have headroom for audio peaks.
BrightEye 54 TM user must take care to verify that a device either has a universal input (capable of 90 to 230 volts, either 50 or 60 Hz), or that a line voltage switch, if present, is set correctly. Interlace Human vision can be fooled to see motion by presenting a series of images, each with a small change relative to the previous image. In order to eliminate the flicker, our eyes need to see more than 30 images per second.
BrightEye 54 Sync Generator and Test Signal Generator NTSC The color television encoding system used in North America was originally defined by the National Television Standards Committee. This American standard has also been adopted by Canada, Mexico, Japan, Korea, and Taiwan. (This standard is referred to disparagingly as Never Twice Same Color.) Optical An optical interface between two devices carries data by modulating a light source.
BrightEye 54 TM RGB RGB systems carry the totality of the picture information as independent Red, Green, and Blue signals. Television is an additive color system, where all three components add to produce white. Because the luminance (or detail) information is carried partially in each of the RGB channels, all three must be carried at full bandwidth in order to faithfully reproduce an image.
BrightEye 54 Sync Generator and Test Signal Generator Time Base Error Time base error is present when there is excessive jitter or uncertainty in the line to line output timing of a video signal. This is commonly associated with playback from video tape recorders, and is particularly severe with consumer type heterodyne systems like VHS. Time base error will render a signal unusable for broadcast or editing purposes. Tri Level Sync An analog sync reference signal that is used in High Definition systems.
