BrightEye 91 HD Upconverter with AES Audio
BrightEye 91 - Page 2
PRODUCT OVERVIEW
BrightEye 91 upconverts standard definition (SD) signals into high definition
(HD) and performs format and aspect ratio conversion as needed. The built-in
frame synchronizer handles any asynchronous signals fed to the unit.
As video is processed, audio is processed too, since the BrightEye 91
accommodates both embedded audio and discreet AES digital audio streams. Up
to sixteen channels of embedded audio are supported. Audio mixing is available
for two of the four embedded audio groups. The AES I/O ports can be configured
for eight channels of audio input, eight channels of audio output, or four in/four
out. The audio mixer can be used for AES channels as well.
The rear-panel HDMI output connector is compatible with many LCD monitors
and allows confidence monitoring of signal feeds.
Basic controls are accessed on the front panel. BrightEye PC and BrightEye Mac
Control applications provide access to video processing functions, input and
output, and audio mixer controls that are not available from the front panel.
FUNCTIONAL DESCRIPTION
As shown in the diagram, when a standard definition serial digital video input is
fed to the BrightEye 91, the signal enters the serial digital receiver and is frame
synchronized to the reference input. Audio is disembedded and passed around the
upconversion process.
Alternately, when analog composite video is fed to BrightEye 91, the analog video
is converted at 14 bits of resolution to digital YCrCb components (601). The signal
is frame synchronized to the reference input and then fed to the upconverter.
Aspect ratio of the video output is selectable between Anamorphic, Pillar Box, or
Crop. It can also be set manually if desired.
External AES audio can be inserted into the SDI stream or replace existing
embedded audio. There are eight AES digital audio ports that can be used for
input or output. There are 3 ways to configure the audio ports: Mux 8 where the 4
AES BNCs are configured as 8 input channels, Mux 4 where 2 BNCs are 4 input
channels and 2 BNCs are 4 outputs channels, and Demux 8 where the 4 AES
BNCs are configured as 8 output channels. Audio level adjustment and channel
mixing is provided.
All 16 channels of audio are passed through. Audio is passed around the
upconversion process in order to preserve lip sync. Audio is embedded into the
video stream prior to output. Of the sixteen channels of audio, you can select one
pair to monitor through the Audio Monitor headphone jack by making a selection
from the
Mon Assign
control on the
Audio Out
menu.
The HDMI output provides confidence monitoring of the same signal that is on
the two HD SDI output BNCs.
BrightEye 91 is powered by a 12 volt DC universal power supply. This power
supply can accept an input voltage between 100 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.
