Model 5152
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 mul-
timedia installations. As a member of the
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 embedder products, Model
5152 embedding operation does not require
an external source of SDI to be connected.
Advanced circuitry within the Model 5152
supports the generation of a broadcast-
standard high-definition SDI signal. And
rather than reproducing a fixed test pattern,
the Model 5152 has the capability to store
and output two custom video images. The
images, one for “720” and one for “1080,”
are based on bitmap (.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. When
a valid HD- or 3G-SDI signal is connected
to the module’s input it will pass through,
unchanged, to the module’s SDI 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 SDI input
signal. This “learning” capability allows a
Model 5152 to automatically adapt to the
SDI format and rate utilized by a specific
facility or application.
An alternate operating mode can be se-
lected, allowing the Model 5152 to serve
as a dedicated video signal generator. In
this mode an SDI signal connected to the
module will serve as an external timing
reference.
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/
