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.
