BrightEye 91

HD Upconverter with AES Audio

Easy To Use

BrightEye 91 is an upconverter with analog composite and
SD SDI inputs. Feed the analog composite or SD SDI output
of a camera to a BrightEye 91 and upconvert to HD. You can
take the HD signal from the BrightEye 91 into a switcher
or projection system. Upconverting existing SD equipment
lets you leverage the equipment you already have and
operate in the HD domain.

A special Mirror Output Mode can be enabled, causing the
output image to be ipped left to right for use with on­camera talent. An external reference input allows genlock
to a house reference. All vertical interval data and closed
captioning is faithfully passed.

Upconvert Before Distribution

While some cameras may have rewire out, using the video
output and upconverting before distribution is preferable
since longer cable runs can be achieved and quality is
superior. Additionally, the BrightEye 91’s reference input
allows you to time the upconverted video output for use
with a production switcher.

Audio Processing

BrightEye 91 handles both embedded audio and discrete
AES digital audio inputs. Sixteen channels of embedded
audio are supported in BrightEye 91. If the incoming video
has embedded audio, the audio will be safely bypassed
around the video processing and lipsync will be preserved.
Audio mixing is available for two of the four embedded
groups of audio.

Front Panel and Software Control

Input selection, gain control, and test pattern controls are
provided through the front panel interface. Audio presence LEDs
indicate which channels are detected. Controls for crop, letterbox
and pillarbox are accessed from the front panel or BrightEye Mac
or PC software. Video and audio levels and the audio mixer can be
adjusted through BrightEye Mac or PC software.

Audio Monitoring

Audio monitoring is easy with BrightEye 91’s convenient 3.5
mm mini jack. Just select the audio channels you want to
monitor from the front panel and plug in a headset.

Monitoring with HDMI

The HDMI connector on the rear of the unit provides a future
proof monitoring interface. Plug it into most LCD monitors
for condence monitoring of your feed.
