Setup/Operating Instructions
BBG-1034-AUD-PRO-DSP Function Menu List and
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.

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. (See COMM Ports
Setup Controls (p. 3-58))

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. (See COMM Ports Setup Controls (p. 3-58))

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)
