Model 5150
Video Generator Module
Introduction
The Model 5150 Video Generator Module
is a unique device suited for a variety of
custom broadcast, post-production, in-
dustrial, and corporate multimedia instal-
lations. As a member of the 5100-Series
of modules, the Model 5150’s compact
size belies its powerful video feature set.
Advanced circuitry within the Model 5150
supports the generation of a broadcast-
standard high-definition SDI signal. And
rather than reproducing a fixed test pat-
tern, the Model 5150 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 5150’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
SDI output. Only when an input is not pres-
ent 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” capabil-
ity allows a Model 5150 to automatically
adapt to the SDI format and rate utilized
by a specific facility or application.
General Highlights
Applications for the Model 5150 include
sports broadcasting booth packages,
“POV” (point-of-view) remote-controlled
camera systems, stadium video interface
(I/O) locations, and government/corporate
facilities. The module’s performance is
completely “pro” with video quality, reliabil-
ity, and installation flexibility matching that
of much larger-scale equipment.
For operation the Model 5150 only re-
quires connection of a few signals. These
consist of SDI inputs and outputs, an
external source of nominal 12 volts DC
and, optionally, two wires associated with
a local RS-485 data bus. Coaxial SDI input
and output support is standard. Optical
input and output support is optional. The
acceptable DC input voltage range is 10 to
18, allowing a variety of power sources to
be utilized.
