A 3G-SDI signal may have two HD sub streams (e.g. for 3-D TV),
AKN as 3G-B standard select between stream 1 or 2 for embedded
audio. See SMPTE 425M for details.
The interface offers a test generator to either check downstream
connections during installation or for use in case of an input fail but you
may also use it to move 16 independent audio channels over a single
coax cable from point to point.

Relay. It provides a shortcut from
SDI-IN to SDI-OUT1 and
disconnects the de-embedder
from the SDI input. This relay
also serves as a fail bypass if
the power is off. This feature
maintains the SDI signal for
downstream equipment.
Will pass the embedded audio
data from the de-embedder to the
embedder 1:1. This function
preserves the original
ancillary data structure.

For compensation of any kind of
audio processing delay within the
chain of devices you may use a
Video Delay. Position "0" turns
off the delay function.
The HD SDI standard allows
for asynchronous audio. This is
critical if you have decided to
synchronize the device on such
signal. Here you find a solution.
You may either use the
embedded word clock or the SDI
carrier itself as a reference.
