BrightEye 94 SD Aspect Ratio Converter
BrightEye 94 - Page 2
PRODUCT OVERVIEW
BrightEye 94 converts standard definition signals from 4:3 to 16:9 or from
16:9 to 4:3. Manual aspect ratio controls are also provided. The built-in frame
synchronizer handles any asynchronous signals fed to the unit. An external
reference input allows genlock to a house reference.
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. Two channels of audio can be monitored on the headphone jack.
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 standard definition serial digital
video input is fed to the BrightEye 94, 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 and audio signals are joined in the embedder. This embedded signal
passes through a serializer to a pair of SD SDI outputs. The HDMI output
provides confidence monitoring of the same signal that is on the two SD SDI
output BNCs. 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 94 is powered by a 12 volt DC universal power supply. This power
supply can accept an input voltage of between 100 and 230 volts, at 50 or 60
