Model 5154
Video Generator/Audio De-Embedder Module
When audio is being de-embedded from
the SDI input signal the de-embedding
process will not change any incoming
audio group data. All embedded audio
signals present on the SDI input will “pass
through” unaltered to the SDI output. This
is important as “downstream” equipment
will often also need access to the audio
content.
It’s important to note that when changing
from an external SDI signal to the internal
generator (or vice-versa) the SDI output
will momentarily lose timing and some
video and audio “glitches” may be present.
For the intended Model 5154 applications
this should not prove to be an issue but is
worth mentioning.
Installation
Integration of the Model 5154 into a select-
ed application should prove quite simple,
only connecting SDI input and output sig-
nals, digital audio outputs, as well as
DC power is required. The coaxial (BNC)
input and output connections are compat-
ible with most HD-SDI and 3G-SDI signals.
If the specific Model 5154 being installed
also includes optical support one or two
single-mode fiber interconnections will be
made. The fiber connections utilize minia-
ture LC plugs.
Four AES3-compliant unbalanced digital
audio outputs are connected by way of a
9-pin D-subminiature (DE-9) connector.
Each of these four digital audio signals
supports two channels of audio.
The DC power source is nominal 12 volts
with an acceptable range of 10 to 18 volts.
It’s possible that the module will be part of
a local RS-485 data bus that’s associated
with a Studio Technologies’ Model 5190
Remote Access Module. If so, two ad-
ditional wires are required to connect the
module to the data bus. After all the con-
nections have been completed the module
can then be secured into the designated
mounting location.
Coaxial (BNC) SDI Output
The Model 5154 provides an SDI output
that utilizes a broadcast-standard BNC
socket. This output is referred to as the co-
axial (BNC) SDI output. Refer to Figure 2
for a detailed view of the connector’s loca-
tion on the rear of the module. The coaxial
(BNC) output, depending on operating
conditions, will be either a SMPTE-
compliant HD-SDI (1.485 Gb/s nominal)
or a 3G-SDI (2.97 Gb/s nominal) signal.
The exact format/rate combinations sup-
ported by the Model 5154 are listed in the
Specifications section of this guide.
Coaxial (BNC) SDI Input
An SDI source can be connected to
the Model 5154 by way of a broadcast-
standard BNC connector. This is referred
to as the coaxial (BNC) SDI input. Refer
to Figure 2 for a detailed view of the con-
nector’s location on the rear of the module.
The coaxial (BNC) input is compatible
with SMPTE-compliant HD (1.485 Gb/s
nominal) and 3G (2.97 Gb/s nominal) SDI
signals. It is not compatible with standard
definition SD-SDI (270 Mb/s nominal) sig-
nals. The exact format/rate combinations
supported by the Model 5154 are listed in
the Specifications section of this guide.
A configuration setting must be made for
the coaxial (BNC) SDI input to be active.
Refer to the Configuration section of this
guide for details.
