Data-Over-Audio sub-tab provides controls that allow
SMPTE 337/338/339 non-PCM data to be embedded and
de-embedded on embedded audio pairs, offering a very
convenient self-contained transport within the program
stream physical media.

SDI IN
The COM Routing tab and appropriate
sub-tab is set to receive serial data, noting
bit rate and parity settings to conform to
the received serial data.
The Data Insertion Source drop-down on
this sub-tab is set for COM 1.

Shown below is an example setup where serial data is embedded as SMPTE 337 non-PCM data on a sending embedded
pair, and then extracted on a receiving pair and converted back to serial data using two cards/devices with the +ANC option.

The received serial data is then directed to
an embedded audio output channel pair by
setting a pair to Embedded Data using the
Output Audio Routing/Controls tab (in
this example, Emb pair 7/8).
B
On the COM Routing tab, select Audio Data Extractor
to extract and route the received SMPTE 337 data to the
desired COM port, noting bit rate, protocol, and parity
settings.
D
The embedded data pair on the receiving end is then
selected using the De-Embed Source select
drop-down on the Data-Over-Audio Setup sub-tab (in
this example, Emb Pair 4 (channels 7/8) as
correspondingly set on the sending card).
C
Notes: • Embedded channel pair selected must be a standard boundary pair (e.g., 1/2, 3/4 and so on).
• SMPTE 337/338/339 embedded pair carrying non-PCM data here is marked as “Non-PCM Data Unknown”. Any intermediate devices between
the Cobalt sending card/device and the Cobalt receiving card/device will transfer this data intact, as long as these devices can transfer in a
bit-accurate manner. Most devices capable of carrying Dolby® streams are capable of this. However, any intermediate devices must have
functions such as PCM level controls and SRC disabled.
When data is successfully being de-embedded, the status
display shows green and indicates the bit rate (bit rate is bit
rate configured on sending end; typically SMPTE 337 data
transfer is much faster than serial)
