HD / SD SDI Dolby
®
Decoder and Audio Multiplexer
Decode incoming embedded or discrete Dolby
®
Digital/E and re-embed into an HD / SD SDI signal.
The MUX-8248 is ideal for decoding incoming Dolby
®
Digital or
Dolby
®
E audio and embedding the AES audio into an
HD / SD SDI video signal. When Dolby
®
Digital or Dolby
®
E is
present on a discrete AES pair or on an embedded audio pair,
the decoder produces up to 10 decoded channels, according to
the Dolby
®
sub-format received by the metadata. The resulting
channels are then available for mapping, inversion and level
adjustment and then embedded into the video signal.
The MUX-8248 offers up to 16 channels of audio embedding,
with the option for up to 8 channels of discrete analog audio.
In addition to the audio proc controls for channel mapping,
inversion and level, 16 channels of selectable sample rate
conversion allows for the re-timing of audio. Full video proc
control, with user memory allows adjustment of white level,
black level, color gain and color phase.
The MUX-8248 can embed Dolby
®
metadata on the SDI output,
sourced from either SDI input video or from the decoder
as desired. With the optional analog / metadata the rear
module’s Dolby
®
Meta output can provide RS-485 metadata for
downstream devices or systems. Metadata on the Dolby
®
Meta
RS-485 output can also be sourced from either SDI input video
or from the decoder as desired.
