BrightEye 75 - Page 2
PRODUCT OVERVIEW
BrightEye 75 converts standard definition analog component or composite video,
or high definition analog component video to SDI with simultaneous 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 75 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 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 (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 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 SDI output on the rear of the unit.
BrightEye 75 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.
