BrightEye 25

Analog Video / Audio to SD SDI Converter
with TBC and Embedder

BrightEye 25 converts analog composite video to SD SDI,
with simultaneous conversion of four channels of audio
and embedding. A TBC/Frame Sync is a standard feature
and allows this BrightEye to work with any sort of video
input. Great for broadcast and desktop applications,
BrightEye 25 can be used with sources such as VTRs and
incoming satellite feeds.

The analog input is converted at 12 bits of resolution and
digitally decoded to 10 bit YCrCb components. The signal is
then time base corrected and frame synchronized to the
reference input. The audio is converted to digital and then it
passes through the built-in four channel mixer with shue
and level control. The video and audio signals join up in an
embedder which can be targeted to any of the four groups.

Basic controls are accessed on the front panel. BrightEye
Mac or PC software provides access to video proc functions
and the built-in audio mixer. The vertical interval can be
passed or blanked. VU indication is provided on the front
panel and through BrightEye Mac or PC software.
