What about wireless distribution components?
It is taking the industry longer to offer completely reliable solutions for
distributing high-quality video wirelessly. Part of the problem is the inability
to consistently transmit full-motion video in real time over an active wireless
connection. Because the technology often involves multicasting video,
audio, and peripheral signals, there are latency issues at a higher resolutions.
Error propagation and latency can make transmittal unreliable if there is
insufficient or shared bandwidth.
Yes, it can be done, but bandwidth is still a limitation. Full HD video
requires a huge amount of bandwidth, limiting distance. Even the best
solutions on the market today are limited to maximum distances of about
30 Meter, and having to go through walls reduces distances further.
Also complicating matters: The wireless video solutions have to share
the spectrum with other wireless services, including regular Wi-Fi. This may
affect the reliability of the wireless video system as well as the Wi-Fi
network, so some planning and careful design is recommended.

Splitters
For displaying images on multiple screens, order a splitter. Unlike CATx-
based broadcasters or multichannel extension products, splitters divide a
PC’s VGA, DVI, HDMI
®
, DisplayPort, or other type of signal without
sacrificing quality.
In some cases, splitters buffer output and drive signals extra distances
without any loss, so they essentially function as extenders, too. They’re
a great choice for splitting signals in retail applications where you want
to keep source equipment in a secure area.
Plus, they’re very easy to set up. In most cases, you just connect the video
cables, power up your system, and you’re ready to start duplicating images
for multiple monitors or displays.
Switches
Available in VGA, DVI, HDMI, and other versions, these enable you to
switch video from PCs with multiple video outputs to a common display.
You can do this manually or set it up to switch automatically based on
input detection. Many switches also come with IR remote control units so
you can switch sources away from the unit itself. Most also include an
RS-232 port for connecting to a serial console.
Matrix versions are available for showing video images from separate
sources on multiple displays, eliminating the need to constantly swap
cables between inputs and outputs.
For instance, if your operation has four PCs and you want to display the
video on one monitor to the other three monitors, a matrix video switch
is what you need to handle the job. In many cases, they can be linked to
a Crestron, AMX, or similar system.
Any source input can be routed to any display output, and their matrix
functionality makes them ideal for command and control rooms where
one has to frequently switch video from multiple sources to multiple
screens. They are also great for video broadcasting, corporate theater,
conference room, and training applications. For easy recall, most matrix
switches store a number of preset routing patterns.
And because many newer HDMI switches are HDCP compliant, they can
be connected to Blu-ray players or other protected-content sources, a
function that enables easy integration into video production environments.
Advanced video and peripheral sharing systems
In some applications, switching just video and audio isn’t enough. You
may also need to access and switch between peripheral USB HID devices
and remotely located computer CPUs or backracked servers, and provide
switching access to more than one employee.
In these applications, a modular video and peripheral matrix switching
system can provide you with the flexibility you require. These modular
crosspoint switching systems enable you to switch between PC CPUs in
applications where HD video is everything. They’re designed to interface
with and enable non-blocking matrix switching of digital video, USB-HID,
USB 2.0, RS-232, and audio ports.
What’s more, they enable you to use the existing cabling infrastructure
for connectivity between a console/CPU and a switch without a media
converter or third-party switching device.
In addition to matrix switching, they may even provide high-performance
routing of HD video, audio, and data for complete signal distribution. In
this instance, they work as extension devices, and like our IP-based
extenders, they use multicasting to distribute signals over a network.
If you don‘t need such advanced switching and extension capabilities, but
just want easy monitoring and switching of video from multiple computer
heads, a KVM type of sharing/switching device may be all you need.
These give you the ability to control multiple CPUs or servers from one
keyboard and mouse plus the ability to display the video from those
multiple servers or servers on one monitor — all at the same time, and in
real time.
In addition to command and control rooms, KVM switches are ideal for
workstations in financial, banking, engineering, graphics, and healthcare.

QUESTI
NS
Contact the experts at 0811/5541-110.
1. Where do you intend to store most of your video
content (on a back-racked server, on a workstation
PC, at a remote office, on an FTP site)?
2. Do you intend to distribute video from a number of
different sources (including Blu-ray or DVD players)?
3. Will you need to integrate a sales CRM system or
other database into your AV distribution system?
4. Do you intend to use RSS feeds or other external
Web content on digital signage?
5. When outputting video from a single source to
multiple displays, do you require extended distance?
6. Will you be transmitting in video areas with
interference or vibration?
7. Do you have CATV or other RF coax wiring
available?
8. Will you need to distribute signals from more than
one source to a display?
9. Will many users, including those in remote offices,
require workstation access to multiple computers for
routing video to multiple screens?
