BrightEye 3 Analog to SDI Converter with TBC/FS

APPLICATIONS

The versatility of BrightEye 3 can be utilized in any number of different applica-
tions where conversion of composite/Y/C and component analog video to SDI is
required.

Analog to SDI/Optical Conversion and Distribution

One application, shown in the illustration below, utilizes the full functionality of
BrightEye 3 by converting an output from a consumer VCR to an SDI signal for
feeding a non-linear editing system. The use of a reference input also allows the
converted signal to be synchronous with the house reference.
