BrightEye 93 HD Cross Converter
BrightEye 93 - Page 2
PRODUCT OVERVIEW
BrightEye 93 cross converts between a variety of HD standards, whether 720p or
1080i. BrightEye 93 auto-senses the input format and cross converts it, based on
the user’s selection of output format. The user only needs to select the preferred
output format. BrightEye 93 will then accept any video input and perform the
proper video conversion as needed. The built-in frame synchronizer handles any
asynchronous signals fed to the unit.
All vertical interval data and closed captioning is faithfully passed. Up to sixteen
channels of embedded audio are supported. If the incoming video has embedded
audio, the audio will be safely bypassed around the video processing and lipsync
will be preserved.
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 following diagrams, when a high definition serial digital video
input is fed to the BrightEye 93, the signal enters the serial digital receiver and is
frame synchronized to the reference input. Audio is disembedded and passed around
the video processing. The video is cross converted to the selected HD standard.
The video and audio signals are joined in the embedder. This embedded signal
passes through a serializer to a pair of HD SDI outputs. The HDMI output
provides confidence monitoring of the same signal that is on the two HD SDI
output BNCs. A pair of audio channels, selected by the user from the Audio Out
menu, can be monitored on the headphone jack.
BrightEye 93 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. 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.

APPLICATIONS
HD Cross Conversion
The BrightEye 93 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 93
where the format is converted to 720p as required for input to an HD router.
