“know” which devices on your IP network want to receive the multicast

packet and who doesn’t. Otherwise, the traffic may be broadcasted to

every end device on your network, slowing it to a halt.

Multcasting isn’t limited to just video either. You can also use it for both

video and peripheral signal extension and sharing (often called “KVM

extension”) applications. These types of extenders feature keyboard/mouse

emulation and emulation for other standard HID devices, while providing

easy access to single-, dual-, or quad-head computers — ideal for

applications requiring multiple graphic heads to be switched simultaneously

from a single workstation. In command and control room setups, for

example, you can multicast video and data to receivers attached to LCDs

in video walls. Users can then interact with computers behind the scenes

using separate keyboard, mice, and digital displays.

Distribution Methods

IP-Based Distribution

IP-based distribution technologies use transmitters

and receivers to extend signals over a TCP/IP

network (a LAN or even a WAN, for instance).

Oftentimes, they’re called IP streamers when used

with codecs. But, when choosing one, be sure

you’re not looking at the consumer-grade devices

for streaming video in small office applications; be

sure it’s a professional-grade multicasting product.

These sophisticated extenders use CATx cabling

infrastructure, but in comparison to standard non-networked CATx

extenders, they multicast data over an active Ethernet network. They do this

by packetizing media streams for delivery over an IP-based network,

so source content can be delivered anywhere you have Ethernet wiring.

By leveraging existing IP network connections to distribute multimedia

content, businesses can avoid running expensive dedicated links from a back

room to digital signage in lobbies or other public areas. Plus, the video is a lot

less susceptible to interference, image skew, and compromised resolution.

Compression makes it possible to run the signal over longer runs — and

compression does not have to mean low-quality video. Compressions may

be lossy or lossless. The IP-based extension methods we’re discussing use

visually lossless compression with algorithms that make it possible to run Full

HD video over the LAN without any visual loss in quality.

They may even simulcast video and audio synchronously so there’s no

latency, feature QoS prioritization and bandwidth-management controls,

and the ability to use bidirectional (two-way) serial signals to query a remote

display to, for example, shut it down and power it on or gather performance

data. What’s more, the system you choose may even support bidirectional

serial connections for use with interactive touchscreens.

Also, they may or may not support existing networking standards.

This is important if you need extra distance in your distribution application. If

they do support Ethernet standards, you can extend video through

networking switches to get extra-long distances, beyond the specified

cabling distances of 328 feet (100 m) per the Ethernet standard.

Because IP-based extenders are based on standardized Ethernet protocols,

you can even use media converters and run several miles over fiber cabling.

Plus, these extenders transmit signals digitally from end to end, so digital

content is never compromised.

Meeting existing standards also allows for ea

sy installation and expansion.

Simply plug in as many receivers as you need for your remote screens and

use a standard Gigabit network switch with IGMP snooping to control

the traffic. IGMP is very important in multicasting. This stops an IP switch

from passing on multicast data onto every port and prevents performance

degradation and wasted network bandwidth. Switches with IGMP support

Picture Quality

Cable Length

Picture quality of an analog

signal gradually declines over

longer lengths of cable.

Picture quality of an digital

signal (e.g. HDMI) suddenly

drops at a certain length of

QUESTI

Contact the experts on 0118 965 6000

1. How far do you need to transmit your video?

Do you want to go farther than 320 feet?

2. Do you have copper (CATx or coax) wiring not in use?

3. How important is video quality? Do you intend to

transmit medical images or detailed graphics renderings?

4. Is bandwidth an issue on your network? Is your LAN

already being used for VoIP or data-intensive applications?

5. Do you want to transmit to one screen or multiple screens?

6. Will you need connectivity to serial touchscreens?

7. Is data privacy an important consideration?

8. Will you be distributing video near machinery?

9. Do your network switches support IGMP snooping?

10. Do you need peripheral support (for instance, for remote

users who require keyboard and mouse control, or for

command and control room applications)?
