-- Signal processing is the “invisible hand” of broadcast
production because it seamlessly works behind the
scenes to reduce overhead costs, ensure downstream
quality and—in the United States—keep
programs from falling out of compliance with federal
The real change for signal processing occurred
years ago when video producers migrated
from the National Television System Committee
standard—a single analog distribution standard—to
a mixed bag of formats, including standard-definition,
high-definition or the format produced by the
Moving Picture Experts Group, known as MPEG.
Therefore, to prepare those formats for broadcast,
signal processing employs video and audio filters to
maximize the display of the output signals, whether
they are video files or video streams.
Today, such devices are ubiquitous and are used
in televisions, DVDs, video codecs and broadcast and

|AJA Video Systems’ FS2
For agencies that produce webcasting, AJA Video
Systems offers its FS2 compact 1RU dual-channel
universal frame synchronizer and format converter.
The FS2 enables frame synchronization, signal conversion,
audio delay control and video “region of
interest” selection from DVI/HDMI sources with the
ability to instantly up-convert content for broadcast.
Each FS2 video channel supports analog component
or composite, 3G/HD/SD-SDI, Dual-Link and HDMI
I/O, as well as optical fiber input/output options.
The company recently released new software
for the FS2 that will support non-broadcast digital
input formats. That enables single-link DVI-D inputs
from computer systems, for example, to be fed into
the FS2 and converted to broadcast signals for use
throughout a production or facility.
“The ability to quickly and easily scale content
sourced from the Web into HD broadcasts in real
time is a feature that our FS2 customers are really
excited about,” said Nick Rashby, AJA’s president.
“Both our broadcast and corporate FS2 customers
require the ability to capture from their desktop
feed for live scaling to HD video, and we’re pleased
to provide them with this feature.”

|Cobalt Digital Inc.’s BlueBox
Cobalt Digital Inc. just released a new version
of its BlueBox Group. The modules attach easily
and securely to cameras or host device chassis for
dependable, uncomplicated installation, the company
said. They receive power directly via USB from
video monitors or other equipment without bulky
and non-secure “wall wart” adapters.

analog audio embed and de-embed and providing
3G (1080p59.94/50) support for HDMI models,
according to Chris Shaw, Cobalt Digital executive
vice president, sales and marketing.
“Cobalt recognized the need for first-class quality
and affordable signal conversion in a compact package,”
Shaw said. “BlueBox delivers exceptional performance
from a small footprint with a full feature list
packed into one convenient converter box,” he said.
|Ensemble Designs’ Avenue Router System
“There are many different flavors of signals that
have to be coded and encoded,” said John Pichitino,
Ensemble Designs’ technology evangelist. “All those
signals have their own unique signatures and formats,
and they all have to be moved through the
process,” and the new collection does not necessarily
play well together, he said.
Ensemble Designs says its Avenue Router System
makes the transition to HD and 3 Gb/s easy for
all types of broadcast television stations and video
facilities. The Avenue Flexible Router includes a
real-time video thumbnails screen, and it is a flexible
matrix, Pichitino said. That means producers
are not burdened with choosing a fixed proportion
of inputs/outputs. Users can choose their own mix
of router inputs and outputs. The device can be
used for quality control monitoring, master control
bypass switching, electronic newsgathering trucks
and edit suites.
Canadian company Evertz offers
a range of complete HD, 3G and
3D end-to-end solutions, including
master control systems, large,
medium and small routers, multi-display monitoring,
production tools and interfaces and closed captioning.
The 7812UDX-HD and 7812UDX-AES8-HD are
broadcast-quality Up/Down/Cross Converters that
convert between common SD/SMPTE 259M and
HD/SMPTE 292M video signals. Those modules
support frame synchronization and external inputs
for video timing adjustment, said Mo Goyal, Evertz
director of product marketing.
“Conversion is one of the key things,” Goyal
said. “It has a built-in program that converts and
links the timing into the house format. It has the
ability to not only manage the audio and video, but
has a bunch of noise reduction technology built in.”
The 7812UDX series incorporates the Mosquito
Noise Reduction and Block Artifact Reduction, which
is a new generation of signal processing technology,
and per pixel motion adaptive spatial-temporal noise
reduction. The 7812UDX series also incorporates
new de-interlacing technologies for superior resolution
and artifact reduction, Goyal said.

Gefen’s new 32x32 Modular Matrix can contain
a mix of both DVI and DisplayPort input boards
combined with DVI, extra long range and fiber

provides routing status, and users can control
the matrix from the front-panel push buttons, the
RS-232 interface or an IP control.
“Users can tailor their matrix by combining different
input and output boards depending on the distance
their displays need to be extended,” Gefen said.

|TVOne’s C3-540 CorioMaster
TVOne, located in
Erlanger, Ky., specializes
audio and multimedia
on its proprietary
Corio video conversion technology.
The company’s C3-540 CorioMaster is a multiviewer
video processor that is suitable for multi-image
video wall productions. Outputs can be grouped
together or individually and can be independently
rotated through 360 degrees in real time, without
adding additional delay, for use in creative video-wall
applications, said Kelly Broderick, marketing manager.
Multiple layouts can be used at the same time or
one layout can be designed to tie multiple projectors
or monitors together as one large image. Up to four
layouts can be used simultaneously, Broderick said.
Control of the CorioMaster is provided by a
multiplatform software package that provides an
intuitive way of setting up layouts and defining the
video canvas to be used for each layout.
New for 2013, the company has produced a
HDBaseT dual output scaling module, adding to
the CorioMaster’s flexibility. The module allows for
the transmission of uncompressed HDMI standard
signals up to 100 meters over good quality Cat-6
network cable. In addition, the use of the scaling
module allows the production display to be located
some distance from the video hardware, using inexpensive,
readily available local area network cabling
with a standard RJ-45 connector.
|Vitec Group’s MGTS Prism
Government broadcasters, such as public, education
and government channels, would be interested in
the Vitec Group’s Mobile Streaming blade the MGTS
Prism, which supports transcoding, encapsulation
to Adobe, Apple and Microsoft streaming formats
with adaptive bit rate, said Michael Chorpash, the
company’s vice president of sales. “Signal processing
is a bit of a loose term, because that could be
processing analog to digital, it could be converting,”
he said. The VPG can be used to convert HD or SD
to a digital H.264 feed, he said.
The PEG channels would be interested in that
product for signal processing because the MGTS
Prism “takes video and digitizes it to fit work flows,”
Chorpash said. “We have some processing features
that will increase the quality and also lower the
latency of the delivery across the network. That’s the
type of signal processing we do.”
