BrightEye 94 TM SD Aspect Ratio Converter User Guide Revision 2.4 SW v1.2.3 This user guide provides detailed information for using the BrightEye 94 aspect ratio converter.
BrightEye 94 SD Aspect Ratio Converter PRODUCT OVERVIEW BrightEye 94 converts standard definition signals from 4:3 to 16:9 or from 16:9 to 4:3. Manual aspect ratio controls are also provided. The built-in frame synchronizer handles any asynchronous signals fed to the unit. An external reference input allows genlock to a house reference. All vertical interval data and closed captioning is faithfully passed. Up to sixteen channels of embedded audio are supported.

BrightEye 94 SD Aspect Ratio Converter Hertz. It uses a standard IEC line cord and can be used anywhere in the world. It is normal for the converter to be quite warm to the touch when operating. PERFORMANCE ADVANTAGES OF THE BRIGHTEYE SERIES When images are converted between different formats, color spaces, and resolution geometries, the need for accuracy and fidelity are extremely important.
BrightEye 94 TM APPLICATIONS SD Aspect Ratio Conversion The BrightEye 94 can perform standard definition aspect ratio conversion to convert the aspect ratio of the SD input signal to a different aspect ratio. In the example below, the input from an SD camera with 16:9 lenses can feed an anamorphic signal to the BrightEye 94 where the aspect ratio can be corrected for input to an SD switcher that requires 16:9 Letterbox.
BrightEye 94 SD Aspect Ratio Converter REAR CONNECTORS All connections to the BrightEye 94 are made on the rear of the unit. Refer to the photo below. BrightEye 94 Rear Connectors 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 Connect a PC or Mac to the USB connector to enable more comprehensive control, diagnostics, and upgrades to the BrightEye 94.
BrightEye 94 TM Ref In This BNC accepts an analog composite video signal or Tri-Level Sync reference which is used as the genlock and timing reference for the internal Frame Synchronizer. Typically the reference signal is Color Black or Color Bars fed from a master sync generator (such as the BrightEye 55). OPERATION Control and operation of the BrightEye 94 is performed from the front panel or remotely from a networked PC with the BrightEye PC or BrightEye Mac Control application.
BrightEye 94 SD Aspect Ratio Converter Status Indicators The following status indicators and controls are provided on the front panel: Embed In Illuminates green when an embedded audio stream is detected on the SD SDI In video input BNC. Mon Vol (Monitor Volume) Illuminates green when audio monitor volume is set to unity, or red when set to other than unity. This control affects the audio headset jack output. Input Illuminates green when a valid SD video signal is detected on the SD SDI In video input BNC.
BrightEye 94 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 94 SD Aspect Ratio Converter GLOSSARY 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). In television systems, these will generally be 48 KHz and either 20 or 24 bits.
BrightEye 94 TM number of bits of resolution, or quantization, will be able to capture a signal with more detail or fidelity. Thus, a video digitizer with 12 bits of resolution will capture 4 times as much detail as one with 10 bits. Blanking The Horizontal and Vertical blanking intervals of a television signal refer to the time periods between lines and between fields.
BrightEye 94 SD Aspect Ratio Converter commonly used format throughout the world, either as PAL or NTSC. It is also referred to as Encoded video. Color Difference Color Difference systems take advantage of the details of human vision. We have more acuity in our black and white vision than we do in color. This means that we need only the luminance information to be carried at full bandwidth, we can scrimp on the color channels.
BrightEye 94 TM can be very cost effective in transmission and routing, but can also add complexity to signal handling issues because the audio content can no longer be treated independently of the video. Eye Pattern To analyze a digital bitstream, the signal can be displayed visually on an oscilloscope by triggering the horizontal timebase with a clock extracted from the stream.
BrightEye 94 SD Aspect Ratio Converter 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 94 TM MPEG The Moving Picture Experts Group is an industry group that develops standards for the compression of moving pictures for television. Their work is an on-going effort. The understanding of image processing and information theory is constantly expanding. And the raw bandwidth of both the hardware and software used for this work is ever increasing.
BrightEye 94 SD Aspect Ratio Converter Oversampling A technique to perform digital sampling at a multiple of the required sample rate. This has the advantage of raising the Nyquist Rate (the maximum frequency which can be reproduced by a given sample rate) much higher than the desired passband. This allows more easily realized anti-aliasing filters. PAL During the early days of color television in North America, European broadcasters developed a competing system called Phase Alternation by Line.
BrightEye 94 TM video. This could refer to standard definition at 270 Mb/s, HD SDI or High Definition Serial Digital video at 1.485 Gb/s, or to the newer 3G standard of High Definition video at 2.97 Gb/s. SMPTE The Society of Motion Picture and Television Engineers is a professional organization which has done tremendous work in setting standards for both the film and television industries. The term “SMPTE’” is also shorthand for one particular component video format - luminance and color difference.
BrightEye 94 SD Aspect Ratio Converter Tri-Level Sync For many, many years, television systems used composite black as a genlock reference source. This was a natural evolution from analog systems to digital implementations. With the advent of High Definition television, with even higher data rates and tighter jitter requirements, problems with this legacy genlock signal surfaced. Further, a reference signal with a 50 or 60 Hz frame rate was useless with 24 Hz HD systems running at film rates.
BrightEye 94 TM YUV Strictly speaking, YUV does not apply to component video. The letters refer to the Luminance (Y), and the U and V encoding axes using in the PAL composite system. Since the U axis is very close to the B-Y axis, and the V axis is very close to the R-Y axis, YUV is often used as a sort of shorthand for the more long-winded “Y/R-Y/B-Y”. Y/Cr/Cb In digital component video, the luminance component is Y, and the two color difference signals are Cr (R-Y) and Cb (B-Y).
