BrightEye 90-F HD Up/Down/Cross Converter and ARC with AES Audio and Optical Output
BrightEye 90-F - Page 2
PRODUCT OVERVIEW
BrightEye 90-F 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-F auto-senses the input format and determines if it should up,
down, or cross convert, based on the user’s selection of output format. The user
only needs to select the preferred output format. BrightEye 90-F will then accept
any video input and perform the proper video conversion as needed.
As video is processed, audio is processed too, since the BrightEye 90-F accommodates
both embedded audio and discreet AES digital audio streams. Up to sixteen
channels of embedded audio are supported. Audio mixing is available for two of
the four embedded audio groups. The AES I/O ports can be configured for eight
channels of audio input, eight channels of audio output, or four in/four out. The
audio mixer can be used for AES channels as well.
The rear-panel HDMI output connector is compatible with many LCD monitors
and allows confidence monitoring of signal feeds.
Basic controls are accessed on the front panel. BrightEye PC and BrightEye Mac
Control applications provide access to video processing functions, input and
output, and audio mixer controls that are not available from the front panel.
FUNCTIONAL DESCRIPTION
As shown in the diagrams that follow, when a high definition or standard definition
serial digital video input is fed to the BrightEye 90-F, the signal enters the serial
digital receiver and is frame synchronized to the reference input. Audio is disembedded
and passed around the video processing.
Alternately, when analog composite video is fed to BrightEye 90-F, the analog
video is converted at 14 bits of resolution to digital YCrCb components (601). The
signal is frame synchronized to the reference input then fed to the upconverter.
Processing for upconversion, downconversion, ross conversion and aspect ratio
conversion is done at 12- and 16-bits. Aspect ratio of the video output is selectable
between Anamorphic, Pillar Box, Letter Box, or Crop. It can also be set manually
if desired.
External AES audio can be inserted into the SDI stream or replace existing
embedded audio. There are eight AES digital audio ports that can be used for
input or output. There are three ways to configure the audio ports: Mux 8 where
the 4 AES BNCs are configured as 8 input channels, Mux 4 where 2 BNCs are
4 input channels and 2 BNCs are 4 outputs channels, and Demux 8 where the
4 AES BNCs are configured as 8 output channels. Audio level adjustment and
channel mixing is provided.
All 16 channels of audio are passed through. Audio is passed around the video
processing in order to preserve lip sync. Audio is embedded into the video stream
prior to output. Of the sixteen channels of audio, you can select one pair to
monitor through the Audio Monitor headphone jack by making a selection from
the Mon Assign control on the Audio Out menu.

BrightEye 90-F - Page 3
The HDMI output provides confidence monitoring of the same signal that is on
the two SDI outputs. When SD SDI is present on the SDI outputs, composite
video will be present on the composite output BNC.
BrightEye 90-F is powered by a 12 volt DC universal power supply. This power
supply can accept an input voltage between 90 and 230 volts, at 50 or 60 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.
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. The BrightEye series
of up, down, and cross converters were designed specifically with this in mind
and provide the highest possible level of signal processing quality.
Key aspects of this design are:
1) The Standard Definition analog inputs and outputs feature 12-bit
quantization, with 4-times oversampling and 4:4:4 internal processing.
This allows for better separation of real image content from artifacts.
2) The RF aspects of the electrical performance of the SDI inputs and outputs
have been carefully optimized for reliable and dependable SDI I/O
performance even under adverse conditions.
3) Input signals are upsampled to 4:4:4 spatial resolution in RGB colorspace
and adaptively de-interlaced. This enables all of the geometrical conversions
of the image to be performed in the Progressive domain. This enhancement
to the temporal resolution of the image is a key contributor to final image
quality, even if the final output is interlaced.
4) The colorspace and geometrical conversions of the signal are performed at
up to 16 bits of resolution.
5) The final output signal is built from this intermediate progressive
workspace, which is the most uncompromised version of the image possible.
It provides the best possible starting point from which to create the final
output signal.

SD Aspect Ratio Conversion
The BrightEye 90-F 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-F where the aspect ratio can be corrected for input to an SD switcher that
requires 16:9 Letterbox.
HD Cross Conversion
The BrightEye 90-F can perform cross conversion between two different types of HD
signals. As shown here, the 1080i input from an HD network feed is sent to the BrightEye
90-F where the format is converted to 720p as required for input to an HD router.

Remote Truck/OB Van
As shown below, the BrightEye 90-F accepts an SD SDI or HD SDI signal. The user sets
the unit to the desired output type. The BrightEye 90-F 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-F is set to output HD 720p. If the incoming signal is
720p, the signal simply passes to the output. If the incoming signal is 1080i, the unit cross
converts the signal and outputs 720p. If the incoming signal is SD SDI, the unit upconverts the
signal and outputs HD 720p.
