Module Description
The IQBRK00 is designed to take up to two
embedded audio streams, break them out to AES
and then re-ingest the resultant signals. The end
result being the ability to insert a pure audio device
into an embedded stream. It can take its audio
input on a channel-by-channel basis from either
the dual AES, the embedded sources or a
combination of both. At the heart of this module is
a comprehensive processing block that provides a
powerful
audio
manipulation
solution.
The
processed audio can be embedded into the SDI
output as well as being fed to the AES outputs.
Each audio output can be fed with a separate
audio combination as necessary. The audio
sources are protected by a firewall that ensures
breaks in the incoming signal do not effect the
output. Video proc. amp. control and a video delay
of up to three frames make this a powerful solution
for the video stream. Audio features include fixed
and tracking delays, channel-level shuffling, proc.
amp controls and assignable four-input mixers for
combining audio sources. The user can choose to
combine audio channels from any of the input
sources - embedded streams and AES inputs.
Bypass paths allow for the passing, embedding or
de-embedding of non-PCM audio such as Dolby E.
Analog audio outputs are also provided to enable
either AES to analog audio conversion or analog
audio de-embedding.
Applications:
De-embed audio output to external dedicated
audio unit (e.g. Graphic EQ, reverb, chain of audio
boxes, etc.), then re-embed its output into the
video stream.
De-embed Dolby E audio stream, pass through
Dolby E decoder, re-embed resulting AES audio.
De-embed AES audio, pass through Dolby E
encoder, re-embed Dolby E stream.
