BrightEye 1

Analog/SDI to SDI/Optical Converter

with TBC and Frame Sync

BrightEye 1 is a comprehensive solution to signal
acquisition. With analog component, analog
composite S-Video (Y/C), and SDI video inputs, it can
take on any video source. The built-in Time Base
Corrector/Frame Synchronizer provides a rock steady
output — even with marginal inputs. The reference
input is used to genlock the converter output to
house reference such as color black.

Front panel controls select input source and format
and adjust video gain. Video levels can be adjusted
through BrightEye PC.

Simultaneous SDI (electrical) and Optical outputs are
provided, so you can deliver the signal just about
anywhere. Both Color Bars and the SDI Checkfield
(Pathological) test patterns are included to facilitate
transmission path testing.
