ClearOne® VIEW® AV Streaming System Powers AV System at New Unilever Singapore Training Facility

 

 

With 24 AV zones spread throughout two buildings, the company now has full, simple control of its expansive AV system.

 

 

SALT LAKE CITY, UTAH, August 15, 2017 — When Unilever, the world’s largest consumer goods company, built its new training facility in Singapore, perhaps the most crucial component was a robust audio/video system that would be easy to use, had no audio lag and could deliver multiple sources to a total of 49 endpoints including digital signage displays. Working with Principle One, a leading technology integration firm with offices in Hong Kong, Singapore, Shanghai and Tokyo, the company turned to ClearOne (NASDAQ:CLRO), the leading global provider of audio and visual communication solutions, and the ClearOne VIEW network streaming system based on Streamnet®-patented technology TCP/IP solution to provide the 24-zone, four-source system that makes the training center more efficient and enjoyable for both employees and trainees…

Yes, 4K Really DOES Matter!

Written on July 13, 2017 at 11:58 am, by

 

I recently read an article titled “Does 4K even matter?” It was a good article with some salient points. I would argue that 4K does matter for a variety of reasons; and I agree with the author that 4K is a tool…and the right tool is going to depend upon the job. 4K makes sense when all the parts in the entire system support 4K or when a customer wants to future-proof an installation and install as many 4K-compatible devices as possible in the project.

 

VIEW® Pro 4K – Encoder

Just as our currently-shipping 2K version of VIEW® Pro; the 4k version supports all of the awesome licensed features that make our ecosystem unique. We offer a composition feature that allows the user to create video walls and/or multi-viewer compositions. The number of sources that can be shown on a video wall or even a single screen is virtually unlimited — and it’s incredibly scalable with no requirement for a video wall processor. Applications span almost any vertical market- from Command and Control Centers to medical appliactions; any customer that requires the highest resolution, best color space (4:4:4), and finest detail.

 

Using both H.264 and H.265 video coding compression, VIEW Pro 4K can ride on existing networks. These streams are 1/10 to 1/100 the size of comparable streams using Motion JPEG or Uncompressed Video offering incredible scalability. In addition, our current VIEW Pro 2K solutions can be intermingled and work in the same installations as our 4K solutions.

 

Another important feature of VIEW Pro is the ability to both ingest and create RTSP streams to work with 3rd-party decoders like VLC. 4K video playback on VLC does have some specific requirements for it to work successfully, including enabling the GPU accelerated feature in VLC. By using the processing power of the graphics card, it will reduce the load on the processer. Newer operating systems with the latest drivers will be required for 4K decoding to work smoothly. Consider an application in a medical or dental school where a professor streams 4K via RTSP for students to pick up on their laptops. Through a 3rd-party control, the professor can switch these streams at will.

 

ClearOne’s 4K VIEW Pro continues the lineage of providing the best value, greatest flexibility, and interoperability with 3rd-party control systems that earns it’s moniker of being the only “true video DSP” in the streaming marketplace.

 

4K encoders and decoders have their places in the AV world, and adoption will continue to grow as the entire industry matures and expands, with all pieces in the chain become 4k-enabled.

Getting Creative With AV over IP

Written on June 22, 2017 at 4:30 pm, by

 

One of the interesting things about AV over IP is that it offers a unique way to accomplish AV communication goals.  The rules change when your sources and end points are routed over a network; and this offers a great deal of flexibility.  An integrator recently presented some design requirements that allow an advantage with this flexibility.

 

The system called for 16 IP cameras on a network that needed to be routed to and controlled from a separate network without any Ethernet connection between the two networks.

 

The 16 cameras are connected to a layer-3 switch.  The IP addresses of each of those cameras are entered as a proxy on the decoder which has an RTSP license for hosting 3rd-party streams.  Each IP camera can provide different resolutions; and by using lower-resolution streams, the decoder does not to scale the video.  With the decoder hosting these RTSP Streams, the decoder now becomes the source into the encoder.  Usually we think of the decoder as the end point, but not in this scenario.  The connection between the two is an HDMI cable.  This addresses one of the primary requirements of the system which is security.  The customer does not want the IP cameras accessible from the network on which they are being viewed.

 

The encoder that is connected to the switch has an RTSP license that allows it to send RTSP streams to 3rd-party devices.  Viewers with access to the “viewing” network can use a soft decoder like VLC to pick up the stream via a URL.  The viewer sees whatever is on that URL which could be any of the 16 camera feeds or a combination of multiple cameras in a layout created in the VIEW® Pro Panorama Software.  The switching between these sources and layouts is accomplished using our VIEW Virtual Matrix software (see links to sample videos below) or our free Virtual Control software.  This GUI can even be accessed via a mobile device.  For more extensive control we offer free modules for all of the popular control systems.

From the ClearOne side, all this requires is a single Encoder with and RTSP License and a Single Decoder with both and RTSP and a Composition license.  While it’s not something you run into every day, it is a unique way to solve a problem.  The end result is a very flexible, scalable and certainly a very cost effective solution.

Video Walls Cannot be That Simple

Written on June 8, 2017 at 10:15 am, by

 

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:

What is 4:4:4 color and why should I care?

Written on March 15, 2017 at 5:45 am, by

 

In the AV industry we pride ourselves on providing the best-quality audio and visual communication to our clients.  One way in which we can do that is to offer video solutions in 4:4:4 color.

 

 

When digital video was first introduced, video files sizes were large in relation to storage and transmission capabilities.  One of the ways to address these larger file sizes was to introduce “chroma sub sampling.”  In digital video there are two main components; Luminance and Chrominance.  Luminance (or contrast) is the difference between the lightest and darkest parts of an image.  Chrominance is the color saturation of an image.  The human eye is very sensitive to small changes in contrast (Luminance) and is less sensitive to changes in color saturation (Chrominance).

 

 

To make digital video files more manageable, compression was introduced.  A true-color video signal (4:4:4) includes all of the red, green, and blue color information of each pixel.  In a 24-bit system, there are 8 pixels for each color and thus 24 bits in true color.  Chroma subsampling reduces file size by removing color.  In the AV world, the most common color space is 4:2:0, which is DVD quality. However, with 4:2:0 quality, the viewer is only seeing 50% of the available color.  To make up for that loss of color, the pixels that were removed are recreated by borrowing or “interpolating” from the adjacent pixels.  In some instances 4:2:0 quality is perfectly acceptable.  In other instances however the chroma sub sampling provides the viewer an experience that is less than optimal.

 

 

I can think of at least three instances in which 4:4:4 color is required:

 

  1. Telemedicine:  Surgical procedures streamed over a network require extremely accurate color information on the receiving end.
  2. Spreadsheets: Small text on a spreadsheet in color is virtually unreadable at anything other than 4:4:4 quality.
  3. Corporate Branding: Accurate color representation in a company logo.  Think of how some iconic brands might appear if the colors were not accurate represented.

 

 

If two video streams with identical content are placed next to each other, one at 720P 4:4:4 color and the other at 1080P 4:2:0, chances are extremely high that the average viewer will choose the lower resolution image with the true color as the more impactful.  Color trumps resolution pretty much every time.  So the next time you are specifying a streaming solution make sure to factor in which color space is most appropriate for the application.

The Power of AV over IP

Written on November 2, 2016 at 11:04 am, by

 

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.

 

 

ClearOne’s StreamNet technology – a high-quality, AVoIP streaming solution that provides digital media distribution with unmatched scalability and ease of deployment on existing IP networks. It supports all types of AV sources to be distributed through existing Ethernet networks to all types of endpoints – from video wall screens to single, large-display screens and laptops or mobile devices.

We’re traveling the states showing off our newest products. Read about our adventure at each stop on the ClearOne Sales Roadshow Tour and be on the look out for us at a city near you.

 

HOUSTON – 1/12/17

This fabulous trek comes to an end in the Lone Star State. The Houston AV practitioners really helped us end on a high note, with unique interest in the Network Media Streaming solutions. The demos and even the networking of peers was a great ending to a productive series of meetings.  We hope to be on the road again in the near future, as we look ahead to more releases, and new innovations!

DALLAS – 1/10/17

 

We started off 2017 with the next-to-last Roadshow in Dallas – the mild weather in direct contrast to the high energy and interest of our attendees as we did hands-on demos of all the Pro Audio, Network Media Streaming, Wireless Mics, and Video Collaboration solutions. The UNITE 200 PTZ camera was of special interest, as well as the overall integration of products, bringing together the best in audio and visual communications with the flexibility to fit any environment!

 

SAN FRANCISCO – 12/8

Rainy San Francisco played home to our last Roadshow of 2016 (Seems strange to call it the last -but  we’ll  be back in January with more locations!)

 

Local Integrators and Consultants learned quite a bit about our latest solutions and found some very interesting possibilities with current projects that may now find some huge cost savings and a wealth of features with audio and video conferencing/collaboration. Many were introduced to the power of our streaming solutions, many not having previously done many of these types of installations. Wireless mics were of great interest with the simple integration and security offered with any pro audio installations.  The simplicity and flexibility of ClearOne’s integrated options really helped open everyone’s world to new solutions!

 ANAHEIM 12/6

Just next door to “the happiest place on earth” we found quite a few smiles of our own, as our local west-coast Integrators and Consultants were opening their worlds to all the newest ClearOne solutions.

 

The hands-on demos lasted quite a long time, as our attendees were finding more and more options for integrated solutions – adding industry-leading video collaboration to their pro audio installations, or vice versa, finding that video conferencing and media collaboration installations would be so much more natural and immersive with ClearOne professional audio integration.

 

Interest in streaming technology were answered with the unique ability to run powerful audio, video, and control over a single cable in a client’s existing TCP/IP network – something that opens up a lot of people’s worlds when no new wiring is required to have an easily installed mesh network for media streaming.

 

ClearOne’s wireless mics held everyone’s attention with the breadth of features and security found in such affordable packages. The flexibility of installations and the ease of use with field-upgradable products made the new wireless mics solutions a hit with everyone.

 

WASHINGTON DC – 11/10roadshow-dc

 

Our nation’s capital seems to be relatively calm after such a heated election season. We had a very productive meeting with attendees in Washington DC, with a session full of insightful questions and interactive dialogue. We heard from many consultants and integrators who were excited about all the newest ClearOne solutions and the expanded offerings they could provide for upcoming installations. Others now had the possibility of revisiting large projects already underway with the ability to offer clients solutions with the full range of features at a lower price than what may have been originally suggested.

All in all, we had a great time in Washington DC and will stay in close touch with our new contacts.  Will we see you at the next stop?

 


TORONTO – 11/1

 

Wroadshow-torontoe reached the far north this week with a visit to Toronto as our team of AV experts ran through the demos of the latest CONVERGE® Pro 2 Pro Audio DSP innovations, Spontania and COLLABORATE® Pro cloud-based videoconferencing and media collaboration (respectively), our affordable – and more importantly, highly secure – new wireless microphones, and the powerful flexibility of VIEW® Pro and its ability to stream across existing TCP/IP Ethernet networks.

 

The Canadian stop was very well-received and we thank everyone who attended! We’ll stay in touch with contacts old and new to support everyone with the latest solutions as a one-stop manufacturing resource.

NEW YORK – 10/20

 

The “Big Apple” of AV practitioners’ eyes

 

 

roadshow-nyc

In the shadow of the Empire State Building, the historic Hotel Pennsylvania played host to ClearOne’s second Sales Roadshow.  High above the never-ending NYC  bustle, integrators and consultants learned all about ClearOne’s latest – ending with a hands-on tour of each major group of solutions.

 

Pro Audio has been redefined- AGAIN!  A live-listening demo of CONVERGE® Pro 2’s noise cancellation provided real-time examples of the latest and most powerful adaptive audio DSP algorithms, including acoustic echo cancellation, noise cancellation, feedback elimination, gain and level control, and microphone gating.

 

The Beamforming Microphone Array 2 raised everyone’s brows, representing the second generation of the most powerful beamforming & adaptive steering technology in the industry – something others are just beginning to explore.  The beautiful, sleek design was preserved, with some new back-panel updates and the  addition of color-matched “feet” to completely blend in with the entire piece. In addition, a standard projector mount option is now available with different suspension column lengths.

 

The affordable new DIALOG® 20 wireless microphone system proved that good things come in small packages. Just two channels, it is the affordable choice for smaller venues requiring few wireless mics – with the option to daisy-chain to expand with more channels- or even be combined with options such as the Beamforming Mic Array 2 & CONVERGE Pro 2!

 

VIEW® Pro again displayed the ease of use with auto-discovery and AV over IP streaming on existing networks. The idea of creating a full video wall and video windowing configuration using PANORAMATM in minutes without running any new cable was astounding.

 

COLLABORATE® and Spontaniatrade; video collaboration solutions fit the new work environments with their multi-use appliance and built-in cloud-based conferencing. Huddle rooms and large conference rooms alike can easily add everything from simple in-room wireless presentation to full, remote media collaboration, all with a single appliance.

HDCP isn’t just another useless acronym

Written on October 11, 2016 at 6:15 am, by

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 Limit Yourself When It Comes To Signal Distribution?

Written on September 27, 2016 at 2:33 pm, by

 

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.
