BrightEye 11-HD TM HD/SD SDI to Analog Converter ENSEMBLE D E S I G N S Revision 2.0 SW v1.0 This user guide provides detailed information for using the BrightEye™11-HD HD/SD SDI to Analog Converter module.
BrightEye 11-HD HD/SD SDI to Analog Converter PRODUCT OVERVIEW BrightEye 11-HD provides HD or SD digital to analog video conversion with the full range of analog output formats available for HD and SD. When an HD input is present, HD RGB or YPrPb are output. When an SD input is present, Beta, SMPTE, RGB, or composite with simultaneous Y/C is put. 12 bit processing and conversion at 8x oversampling produce the best looking images possible. Output format and gain are controlled from the front panel.

BrightEye 11-HD TM OPERATION Control and operation of the BrightEye 11-HD converter is performed from the front panel or with the BrightEye PC or Mac 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 of the converter, shown in the figure below, provides status indicators and control over output selection and gain.
BrightEye 11-HD HD/SD SDI to Analog 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. 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 11-HD TM UsingThe 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 11-HD from a personal computer. Installation and instructions for using this software application are given in the PDF manual on disk. If the BrightEye 11-HD is connected to a computer running this software, the following menus are available for controlling and monitoring the unit.
BrightEye 11-HD HD/SD SDI to Analog Converter • Setup – check the box to add setup to the composite output signal (525 SD mode). Leave the box unchecked for no setup. This control is only available on BrightEye PC or Mac. There is no front panel control or indication of this setting. Setup will be grayed out when a SMPTE, RGB, 625, or HD input signal is present.

BrightEye 11-HD HD/SD SDI to Analog Converter 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 11-HD 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 11-HD HD/SD SDI to Analog Converter 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 11-HD TM IEC The International Electrotechnical Commission provides a wide range of worldwide standards. They have provided standardization of the AC power connection 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.
BrightEye 11-HD HD/SD SDI to Analog Converter 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. This will degrade the ability of the fiber to be used over long distances. See also Single mode.
BrightEye 11-HD TM 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. This will create impedance matching errors, especially at higher frequencies.
BrightEye 11-HD HD/SD SDI to Analog Converter TBC 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. This operation is closely associated with the actual digitization of the analog signal because the varying position of the sync timing must be mimicked by the sampling function of the analog to digital converter.
