BrightEye 25 A-D Converter with TBC/FS and Embedder
PRODUCT OVERVIEW
BrightEye™ 25 converts analog composite video to SDI with simultaneous conver-
sion 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.
BrightEye 25 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 Control application
provides access to video proc functions, input/output and built-in audio mixer
controls not available from the front panel.
A glossary of commonly used video terms is provided at the end of this user guide.
FUNCTIONAL DESCRIPTION
As shown in the functional block diagram below, analog video is converted at
12 bits of resolution and digitally decoded to YCrCb components (601). 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 and then passes through the built-in four
channel mixer with shuffle and level control. One of the four audio groups is
selected for embedding into the SDI output.
The video and audio signals are joined in the embedder. This embedded signal
passes through a serializer to two timed SDI outputs on the rear of the unit.
BrightEye 25 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.
