It can seem daunting – creating content on such a large canvas for public consumption. Video walls make a huge impression (pun intended) for lobby areas, informative signage, or even retail use. Even with the hardware setup, just configuring the sources to appear as desired can be a time-consuming task… at least until now.
Auto-discovery of sources can be key to saving time — and sanity — with a video-wall project. The foundation of a fully expandable mesh network of sources and endpoints makes the concept nearly nirvana, and VIEW® Pro delivers. It’s really that simple, with one screen or many, and the PANORAMA software license, you can add a video wall to your existing network, and configure it literally in minutes.
Watch these examples, to see just how easy it can be with our latest VIEW Pro Features and Tips:

Traditionally, AV content is distributed using fixed hardware matrix solutions – a method still being used in some projects. This method will have one piece of hardware with fixed number of inputs and fixed number of outputs; all the sources and destinations being connected to this same box.
There are some major disadvantages in using this traditional method. To name just a few:
a) Multiple racks of equipment and more footprints are needed
b) Expensive, specialized, and source-dedicated cables are needed
c) Complex installation and maintenance is required
d) Cable restriction for length limitation is a consideration and even it may pick up noise and distortion
e) Rigidity is a reality – the system is neither scalable nor flexible. For example: Starting with one 16×16 (sources x destinations) unit, a customer would face purchasing another entire 16×16 system should they need to add just two more channels…a 32×32 system in which only 18×18 are being used.
The modern and new way of distributing AV contents is through TCP/IP Ethernet network. To explain simply, the source devices are connected to a device called an “Encoder.” The destination devices are connected with a device called a “Decoder.” The Encoders and Decoders are connected with an Ethernet Network Switch.
There are countless advantages in using this new method. To name just a few:
a) Highly scalable: Any source to any destination in any combination of the inputs/outputs can be connected in the system. Add a device when needed and if needed.
b) No distance limitation in the network.
c) Highly flexible, including video, audio, data, and control – all in the same network. Can extend the system by increment of 1 unit (unlike the purchasing scenario above!)
d) Highly reliable with high-quality signal transmission over standard Ethernet networks, using standard CAT5e/6 cables.
e) Internet Protocols are matured and standardized for interoperability and are future-proof.
f) Highly affordable, using the existing IP network infrastructure that includes the switches and cables.
g) Ease of installation and maintenance.

Have you ever heard of HDCP? Ever wondered what it really means or why it exits?
HDCP is an acronym for High-bandwidth Digital Content Protection. It is a form of digital copy protection that was developed by Intel with the intention of preventing the copying of digital audio and video content as it travels across connections. Being that HDCP is a digital technology, HDMI and DVI cables are used.
HCDP becomes relevant when it comes to moving audio and video signals over a network…..AV over IP Video Distribution. If a signal is protected by HDCP, once that signal is put into a video distribution system, it will pass if the device the signal is flowing into is HDCP compliant. There are two general standards in the HDCP world….1.4 and 2.XX. Without getting into the details on either, suffice it to say that in a professional AV Distribution System, the equipment you use should be compliant with both in order to provide both a legal solution and one that is flexible for your clients needs.
In our industry one of the main challenges that integrators face is with Apple. Using an Apple device as a source into an Encoder can create an issue even if the content being played is not HDCP protected. AV Integrators have told me that their customers often call and say that their Apple Device is not passing audio and video even when the content being played is not HDCP encrypted. By default Apple has HDCP Content protection enabled on their devices. Apple has presumably taken this route so they will not be liable for the actions of an end user.
To get around this, some encoding and decoding devices have a switch that enables them to turn HDCP off. In theory this appears to be a viable solution. The reality however is that the HDCP licensing agreement that all manufactures who wish to be in compliance sign, does not allow for this work around.
With ClearOne’s View Pro System we fully support the HDCP standards of 1.4 and 2.XX. Our View Pro AV over IP Streaming Solution will never block protected or unprotected content. There is never a need to turn HDCP off. ClearOne has taken the position to comply with HDCP Licensing to the letter of the law.

Why AV over IP?
Back when I first started my career in AV, signal distribution was much simpler. As we progressed in this exciting industry; along came the need of distributing signals further with much larger matrices. We then began to see the influx of UTP and Category cabling.
The AV industry thought these concepts and said, “Hey we can utilize this!” But this presented the problem of the number of pairs. Category cabling only has four pairs, which means distributing audio, video, and control at the same time becomes a challenge… four pairs just aren’t enough. In order to make things work, we needed to packetize. We needed to become digital – which, as you know is exactly what happened; and, to this day, works extremely well.
It begs the questions why haven’t we completely adopted this as an AV industry standard?
Here are a few points to think about when signal distribution is on your plate.
- Will my design need to expand in the future?
- Do I already have category cable in place?
- Will I need to control the device at the destination of the signal or the source for that matter?
- Do I have the need for a processing of my signal such as video wall modes?
All network media solutions are not the same. ClearOne’s VIEW® Pro allows you to design signal distribution systems that are completely future-proof and fully expandable. VIEW Pro gives you the ability to take any audio, video, or control signals and stream them to virtually any location. This is what you would expect; and what most manufactures offer. However, ClearOne solutions also have processing built right in that allows you to adjust virtually every single part of your signal. In addition, we also have other integrated options such as video-wall processing and composition modes.
Regardless of what your distribution needs may be, please take a moment and review ClearOne’s innovative Network Media Steaming offerings. You may just find yourself also asking why this isn’t the AV Industry standard!
We’re here to help. We’d love to hear from you and discuss your AV distribution needs.

A lot can be said for standards. For instance, could you imagine how difficult it would be if the gas pedal wasn’t always on the right? Look at the recent troubles several car manufacturers have had, including lost lives over messing around with how an automatic transmission’s shift level works.
Standards work in all parts of life. So, as AV professionals, why have we had a variety of non-standard ways of delivering content?
The excitement of AV over IP products implies that maybe we will start using standards to replace balun and HDBaseT products for a more standards-based approach. But the more IP products that come to market, the more proprietary streaming products that emerge. The trouble with a proprietary stream is it locks the end user into a single solution, with limited expansion capabilities.
With a true standards-based solution, you can build an eco-system of devices, but are not tied to a single manufacturer, you can mix and match based on budget, features and the architecture of the system. ClearOne’s VIEW® Pro streaming solution leverages the power of H.264 streaming, thereby using visually Loss-Less streaming algorithms, to allow crystal-clear, ultra-high-quality audio and video at very low latency, all at a very low overall bandwidth (typically 8MBb/s). Additionally, based on what the clients’ needs are, we can control and manipulate streams that we don’t even encode, such as those natively streamed from an IP security or PTZ camera, or a conferencing codec with H.264 capabilities or from a computer on the network. Similarly, if perfect frame synchronization is not required, or the need for video windowing, or other advanced features is not required at some displays, there are many, easy, low-cost ways to decode the stream, such as Apple® TV or other H.264 stream viewers, or simply watch the stream on a PC, MAC, IOS or Android device.
By leveraging the power of Standards, we open the client to an eco-system of devices that will be a viable signal distribution infrastructure that will stand the test of time. To take this one step farther, ClearOne’s VIEW® Pro solution leverages H.264 streams, yet provides ULTRA low latency, low bandwidth and the best possible image quality, yet provides advanced capabilities like Video Wall processing, windowing processing and other neat features like USB HID and native RTSP and UDP streaming.
If you haven’t tried VIEW® Pro yet, why not? I’m sure it will exceed you current standard.
VIEW® Pro streaming encoders & decoders lead the industry in sending high quality h.264 video and audio over an existing IP network; but you probably already knew that. What you may not have known are the brilliant and flexible control capabilities of this technology.
In this post, we’re going to take a look at controlling devices via RS-232 and how you can use this power to take over the world, well, maybe just a client’s displays and audio outputs.
As an integrator, you’ve labored for several weeks (and weekends), up and down three flights of stairs, installing a multitude of displays for a client. You’re now hoping to solve the problem of powering on/off monitors, and to make it easy for the end user to select which source to show on any of the multitude of new displays. VIEW® Pro is the answer; allowing you to create an ASCII command list in the Dealer Setup software and then selecting that list using the Serial to Command selection on the Sources tab of any encoder being used in your streaming project.
The true efficiency of this “mesh network” setup is that you need only have the command list on one device, then using the magic of AV over IP, you can send those serial commands to any decoder on your network to perform the functions you’ve programmed. These commands can include the Active On/Off of the decoders themselves as well as Monitor Power On/Off which would of course require a serial cable from the decoder to the display. The D210 decoder is designed to mount directly behind a display with its small design, making this feature perfect for that model.
Additionally, commands such as Source Select can be used to change which sources are being played on any decoder on your network. Using a 3rd-party controller, such as a Crestron device, connected to the serial port of any available encoder or decoder, a savvy integrator could then program a stylish interface for powering displays on and off as well as providing the client an easy-to-use GUI for changing what video and audio is being played throughout the organization.
To expand on this ability, integrators can use VIEW® Pro’s new 2 way rs-232 pass through allowing use with ANY of the popular control system such as Utelogy, AMX, and the aforementioned Crestron to “pass-through” any driver over IP and extend the power and reach of the control system.
This control feature is included with all of our VIEW® Pro streaming product lines, with no additional upgrade or licensing. Competitors don’t offer this method of control with their streaming devices. Think about the possibilities you can provide for your clients. Not only are you giving them the industry leading 4:4:4 color space of vibrant, crystal-clear video with the lowest latency times; you’re offering built-in control that allows you to provide a professional AV over IP solution with fewer devices and affordable upgrade licensing across their existing networks.
Look into ClearOne’s VIEW® Pro streaming encoders & decoders for your next project and see why we are taking the industry by storm with our network media streaming solutions. You know us for audio, and now you know why “we do video.”
