BrightEye 90-A TM HD Up/Down/Cross Converter and ARC with Analog Audio User Guide Revision 2.4 SW v1.2.3 This user guide provides detailed information for using the BrightEye 90-A HD up/down/cross converter and aspect ratio converter (ARC) with analog audio output.
BrightEye 90-A HD Up/Down/Cross Converter and ARC with Analog Audio PRODUCT OVERVIEW BrightEye 90-A upconverts standard definition (SD) signals into high definition (HD), downconverts HD signals into SD, cross converts between a variety of HD standards, and performs format and aspect ratio conversion (ARC). The built-in frame synchronizer handles any asynchronous signals fed to the unit.
BrightEye 90-A TM The HDMI output provides confidence monitoring of the same signal that is on the two SDI output BNCs. When SD SDI is present on the SDI outputs, composite video will be present on the composite output BNC. BrightEye 90-A is powered by a 12 volt DC universal power supply. This power supply can accept an input voltage between 100 and 230 volts, at 50 or 60 Hertz. It uses a standard IEC line cord and can be used anywhere in the world.

BrightEye 90-A TM 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. Whether upconverting from standard definition to HD formats, converting between different HD formats, or downconverting to SD, extra care must be paid to every aspect of the signal and the content of the images.
BrightEye 90-A HD Up/Down/Cross Converter and ARC with Analog Audio APPLICATIONS HD Upconversion 1 The BrightEye 90-A can upconvert SD video from many different source types. As shown in the example below, the SD ingest signal from a satellite is fed to a BrightEye 90-A where it is upconverted to feed an HD Master Control Switcher. The other output can be sent to other HD destinations.
BrightEye 90-A TM HD Downconversion 1 As shown in the example below, the HD ingest signal from a satellite is fed to a BrightEye 90-A where it is downconverted to feed an SD Master Control Switcher. The other output can be sent to another SD destination. SD Master Control Switcher SD SDI HD Signal In BE 90-A Downconversion Other SD Destination House Reference HD Downconversion 2 As shown in the example below, the BrightEye 90-A can be used to downconvert material originated in HD.
BrightEye 90-A HD Up/Down/Cross Converter and ARC with Analog Audio SD Aspect Ratio Conversion The BrightEye 90-A 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 90-A where the aspect ratio can be corrected for input to an SD switcher that requires 16:9 Letterbox.
BrightEye 90-A TM Remote Truck/OB Van As shown below, the BrightEye 90-A accepts an SD SDI or HD SDI signal. The user sets the unit to the desired output type. The BrightEye 90-A auto-senses the input format and determines if it should up, down, or cross convert the signal, based on the user’s output format selection. In this example, the BrightEye 90-A is set to output HD 720p. If the incoming signal is 720p, the signal simply passes to the output.
BrightEye 90-A HD Up/Down/Cross Converter and ARC with Analog Audio REAR CONNECTORS All connections to the BrightEye 90-A are made on the rear of the unit. Refer to the photo below.

BrightEye 90-A HD Up/Down/Cross Converter and ARC with Analog Audio 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 90-A 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 90-A HD Up/Down/Cross Converter and ARC with Analog Audio 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 90-A 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 90-A HD Up/Down/Cross Converter and ARC with Analog Audio 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 90-A 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 90-A HD Up/Down/Cross Converter and ARC with Analog Audio 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.
BrightEye 90-A 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 90-A HD Up/Down/Cross Converter and ARC with Analog Audio 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.
BrightEye 90-A 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 longwinded “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).
