BrightEye 70

HD/SD AES Embedder / Disembedder

The BrightEye 70 is a dual rate eight channel audio
embedder or disembedder for 1.5 Gb/s high denition video
signals or for 270 Mb/s standard denition signals. Four
AES ports automatically congure as inputs or outputs
depending if the module is congured as mux or demux.

When congured as a multiplexer, the BrightEye 70 has one
serial digital video input and four AES audio inputs. These
four AES streams are embedded into the video stream.
AES inputs are sample rate converted, allowing the use of
asynchronous audio. The output of the module is a digital
stream that contains the original video signal and four AES
pairs.

When congured as a demultiplexer, audio signals present
in the incoming video signal are extracted and delivered as
standard AES digital audio streams.

The BrightEye 70 includes an eight channel audio mixer
with channel swap and shue capability that allows
you to completely re-arrange and re-mix audio channels.
It provides precise control over audio level, with up to
12 dB of gain to compensate for low level sources. All
audio processing is performed at full 24 bit resolution
by a digital signal processor (DSP). Delay is adjustable
up to one second. The Data mode operation allows
embedding or disembedding of Dolby E or AC3 signals.
