BrightEye 76 HD/SD Analog to Digital Converter With Optical Output

BrightEye 76 - Page 2

PRODUCT OVERVIEW

BrightEye 76 converts standard definition analog component or composite video,
or high definition analog component video to SDI on an optical output with simul-
taneous conversion of two channels of audio and embedding. A TBC/Frame Sync is
a standard feature and allows the BrightEye to work with any type of video input.
BrightEye 76 is versatile enough to handle applications from broadcasting to
desktop video with sources such as VTRs and incoming satellite feeds.
Basic controls are accessed on the front panel. The BrightEye PC and Mac
Control applications provide access to video proc functions, input and output, and
built-in audio mixer controls that are not available from the front panel.

FUNCTIONAL DESCRIPTION

As shown in the functional block diagram below, analog video is converted at 
14 bits of resolution and digitally decoded to YCrCb components. The signal is
then time base corrected and frame synchronized to the reference input. Proc amp
adjustments are provided for the converted video.
The audio is converted to digital then passed through the built-in 2-channel mixer
with shuffle and level control.
The video and audio signals are joined in the embedder. This embedded signal
passes through a serializer to an optical SDI output on the rear of the unit.
BrightEye 76 is powered by a 12 volt DC universal power supply. This power
supply can accept an input voltage between 90 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.
