BrightEye 91-A
HD Upconverter with Analog Audio
Easy To Use
BrightEye 91-A 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-A and upconvert to
HD. You can take the HD signal from the BrightEye 91-A 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 on-camera 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-A’s reference input
allows you to time the upconverted video output for use
with a production switcher.
Audio Processing
BrightEye 91-A handles both embedded audio and eight
analog audio inputs. Sixteen channels of embedded audio
are supported in BrightEye 91-A. 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.
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 condence
monitoring of your feed.
Front Panel and Software Control
Input selection, gain control, and test patterns control 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-A’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.
