BrightEye 90-F HD Up/Down/Cross Converter and ARC with AES Audio and Optical Output
BrightEye 90-F - Page 2
PRODUCT OVERVIEW
BrightEye 90-F upconverts standard definition (SD) signals into high definition
(HD), downconverts HD signals into SD, cross converts between a variety of HD
standards, and performs format and aspect ratio conversion (ARC). The built-in
frame synchronizer handles any asynchronous signals fed to the unit.
BrightEye 90-F auto-senses the input format and determines if it should up,
down, or cross convert, based on the user’s selection of output format. The user
only needs to select the preferred output format. BrightEye 90-F will then accept
any video input and perform the proper video conversion as needed.
As video is processed, audio is processed too, since the BrightEye 90-F 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 diagrams that follow, when a high definition or standard definition
serial digital video input is fed to the BrightEye 90-F, the signal enters the serial
digital receiver and is frame synchronized to the reference input. Audio is disembedded
and passed around the video processing.
Alternately, when analog composite video is fed to BrightEye 90-F, the analog
video is converted at 14 bits of resolution to digital YCrCb components (601). The
signal is frame synchronized to the reference input then fed to the upconverter.
Processing for upconversion, downconversion, ross conversion and aspect ratio
conversion is done at 12- and 16-bits. Aspect ratio of the video output is selectable
between Anamorphic, Pillar Box, Letter 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 three 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 video
processing 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.
