Video Generator/Audio Embedder Module
Introduction
The Model 5152 Video Generator/Audio
Embedder Module is a unique device
suited for a variety of custom broadcast,
post-production, industrial, and corporate
multimedia installations. As a member of
the extensive 5100-Series of modules,
the Model 5152’s compact size belies its
powerful video and audio feature set. At its
most basic, the Model 5152 provides the
ability to embed up to eight audio channels
(four AES3 digital audio “pairs”) into an
SMPTE®-compliant HD- or 3G-SDI video
“stream.” Unlike most stand-alone embed-
der products, Model 5152 embedding op-
eration does not require an external source
of SDI to be connected. Advanced circuitry
within the Model 5152 supports the genera-
tion of a broadcast-standard SDI signal.
And rather than reproduce one fixed test
pattern, the Model 5152 has the capability
to store and output two custom high-defi-
nition video images. The images, one for
“720” and one for “1080,” are based on bit-
map (.bmp) files that can be created using
a personal computer’s graphics program.
For convenience, the .bmp files are loaded
into the module’s nonvolatile memory via a
standard USB flash drive. The appropriate
“720” or “1080” image is automatically con-
nected to the SDI output whenever an SDI
input signal is not present. This ensures
that an SDI output signal is always sent to
equipment further along the signal chain.
The Model 5152’s video signal generation
capability can be extremely useful, serv-
ing as both a “keep-alive” signal as well as
allowing a detailed graphics image to be
displayed for identification purposes. To
clarify, when a valid HD- or 3G-SDI signal
is connected to the module’s input it will
pass through, unchanged, to the module’s
output. Only when an input is not present
will the custom image be generated. The
format and rate of the custom image will
match that of the previously-connected in-
put signal. This “learning” capability allows
a module to automatically adapt to the SDI
format and rate utilized by a specific facility
or application.
General Highlights
Applications for the Model 5152 include
sports broadcasting booth packages,
“POV” (point-of-view) remote-controlled
camera systems, stadium audio/video
interface (I/O) locations, and government/
corporate facilities. The module’s perfor-
mance is completely “pro” with video and
audio quality, reliability, and installation
flexibility matching that of much larger-
scale equipment.
