Software MCU Comparison – What does the market offer?

A Videoconference Multipoint Control Unit (MCU) is a crucial part of every serious Videoconference infrastructure. It’s a system used to connect multiple media streams into a single Videoconference, therefore very often the MCU is referred to as a “bridge”.

The traditional MCU is a DSP (digital signal processing) based hardware whose primary functionality is to decode all incoming media streams, compose a single stream for each far-end participant and finally re-encode that stream before sending it out, needless to say all this requires a huge amount of processing power. More over, hardware-based MCUs define scalability on a per-port basis, which means if we want to have more participants connected in a Videoconference at the same time, we need MCUs with more video ports i.e. more DSPs and DSP hardware does not come cheap.

That is why a lot of companies are turning their attention towards a new type of product when it comes to multipoint Videconferences – the so-called “software MCU” or soft-MCU. A soft-MCU serves the same purpose as the hardware-based, except that all the transcoding and signal processing is done in the software which introduces big advantages in terms of cost, scalability and flexibility.

The soft-MCU eliminates the need for DSP hardware and can run on virtualized servers on private or public clouds, therefore it is significantly cheaper to deploy than the expensive hardware MCU. In terms of scalability, customers can often just purchase the number of ports they require at the time and then scale up or down easily as the need changes. Software MCUs offer also more flexible deployment, updates and feature enhancements are easy and more frequent, which gives them advantage in today’s fast evolving demands in the Videoconferencing world. Manufacturers can offer the soft-MCU for on-premise deployment on company’s internal servers (usually preferred by enterprises) but the lower end of the group video conferencing market will also benefit from the hosted services (cloud services) offered by providers.

Current market of Software MCU solutions

Although still in relatively early phase in terms of adoption, the market is all but short in offering soft-MCUs solutions for multipoint Videoconferencing. Some of them offered as pure software to be installed on industry-standard servers, some of them require some sort of hardware usually from the same provider which makes them a kind of  “hybrid” solution. I will just go briefly through some of the most talked about products out there at the moment:

 Avistar

Avistar offers the Avistar C3 Conference, a software-based MCU that runs on standard off-the-shelf hardware and operating system software, and on virtualized servers. It is mainly designed for on-premise deployment in enterprise environments, but service providers offering managed Videoconferencing services could also take advantage from it.

Each conference server can support up to 12 ports of simultaneous conferencing, video standards supported are H.263 and H.264 up to 1024 kbps call rate per endpoint with 30 fps.

 Polycom

The Polycom RealPresence Collaboration Server 800s, Virtual Edition is a multi-protocol, integrated, software-based multipoint MCU running on x86 servers. Mainly designed for mid-sized enterprises or to expand an existing RealPresence Collaboration Server (RMX) environment, it provides open standards scalable video coding (SVC) support and interoperability with systems that use advanced video coding (AVC). It can support up to 40 H.263 or H.264 video ports with 720p and 30 fps.

 Vidyo

Vidyo solution consists of Vidyo Router at its center, offered also as a virtual edition (VE), which performs transcoding-free packet switching using their patented Adaptive Video Layering (AVL) technology which introduces low-latency video-streams for endpoints over any IP network. It can be deployed on industry standard servers and is “VMware Ready” certified. Interoperability with legacy systems requires the use of VidyoGateway. The VidyoRouter VE comes in two models – VE 100 and VE 25 offering 100 and 25 concurrent HD connections respectively, supporting native rate and resolution matching per endpoint, up to 1440p at 60fps. Vidyo technology is available through service providers such as Videoconference24.

 Pexip

Pexip is a new start-up that offers pure-software based MCU called Infinity, which will be available from September. It can be deployed on industry-standard servers in a VMware virtualized environment and port capacity can be easily scaled up by adding more servers. It will support H.263 and H.264, SVC, VP8 video codecs as well as interoperability with WebRTC and Lync. We are yet to see how this product will perform in the real-world but it definitely looks promising with of supporting wide range of software clients and endpoints.

Acano

Acana Software MCU Example

Acano is also also a new player in the industry, offering software solution that unites “previously incompatible audio, video and web technologies” in “coSpaces” which are essentially cloud virtual meeting rooms. People can use whatever devices they have to call into a coSpace, including mobile phones, tablets, PCs, Microsoft Lync clients or video endpoints. Designed for the x86 architecture, it runs on their optimized hardware, standard servers, as well as in virtualized environments and can support thousands of users per server, with further scale and resilience provided by native clustering. Major video standards are supported including H.264 AVC, SVC, WebM / VP8, Microsoft RTVideo, and said to support H.265 as well.

 Vidtel

Vidtel is primarily a service provider; does not offer soft-MCU for on-premise enterprise deployment, but they do offer hosted cloud Videoconferencing solution, labeled MeetMe – it’s a cloud-based, “any-to-any” video conferencing service which supports interoperability between SIP, H.323, Google Talk, Skype, and WebRTC. It supports up to 20 video conferencing endpoints with 720p. The infrastructure for video conferencing is hosted on a Vidtel central cloud and each participant is given a private meeting room ID and a login PIN; they use this to join the Vidtel MeetMe meeting and start communicating and interacting almost as if they were in the same office.

 LifeSize

LifeSize UVC Multipoint is a software-MCU that can be installed on industry-standard servers. It supports H.263 and H.264, SVC video standards and interoperability with Lync (Microsoft RTVideo). Customers can purchase and scale one port at a time and administrators can selectively control the quality and capacity of each port, ranging from 360p for mobile users to 1080p for room-based environments (with the Enterprise edition) and maximum of 128 participants in a single conference.

 Cisco

Cisco became the undisputed king in Videoconferencing hardware, with the acquisition of Tandberg, but they do not offer software-MCU that can be deployed on-premise. They do however offer cloud Videoconferencing service called – Cisco WebEx Telepresence, which can support up to 12 participants per conference with 1080p. At the moment it’s only available in the U.S. and Canada.

 Blue Jeans Network

Blue Jeans – similar to Vidtel, Blue Jeans is a service provider offering hosted hosted video bridging with multi-vendor interoperability including Skype and Lync. Also they are the developers of their own solution and allow re-selling. It supports up to 25 participants per meeting with 720p at 30 fps  and offers easy web based management capabilities for administrators as well as reporting capabilities.

 Avaya / Radvision

Avaya / Radvision is offering the Elite 6000 Series – software-based hybrid multi-point control unit providing high port density up to 40 full 1080p HD ports (80 720p) on a single 1U system. All the major video standards are supported as well as interoperability with other vendors.

As we can see there are lots of different flavors and there are more solutions out there, opening new opportunities for those who could not own standalone MCU before. It’s hard to say what the future holds, certainly it’s too early to dismiss hardware-based MCUs in which companies have invested a lot of money. It’s clear that the two solutions will coexist for some time and it’s up to the customers to choose the best solution for their business based on their requirements in usage, cost and features.

What is WebRTC? – Overview for Busy People

webrtc, logo, chat, bubble, shapes, colours, colorsNo other topic is roaming the news and social media as much as WebRTC these days. But what is WebRTC and what should it mean to you?

Today I would like to give you an overview around this trend and where it came from. In this article I would like to try out the “For Busy People” article format by consolidating all hot topics into quick facts to add value to you without getting side-tracked. I know you busy people are busy and so you can just skip the parts of the article that you are not interested in.

What does WebRTC stand for?

WebRTC means Web Real-Time Communication, so we are talking about ways to communicate without any delay, based on a web-browser, without the use of software that needs to be installed beforehand.

What is WebRTC?

WebRTC is an open framework for placing real-time communication components on web-pages and is controlled by the World Wide Web Consortium (W3C), who are also taking care of other web-standards such as HTML, XML, CSS and others. WebRTC components could include methods such as VoIP, Instant Messaging (or just “chat”), video conferencing or a combination of these. Personally I would count WebRTC to the umbrella of Unified Communications, but the actual use of the WebRTC solutions depend on each enterprise.

Where does WebRTC come from?

WebRTC technology was first developed by Global IP Solutions (or GIPS), a company founded around 1999 in Sweden. In 2011 GIPS was acquired by Google and the W3C started to work on a standard for WebRTC. Since then Google and other major players in the web-browser market, such as Mozilla and Opera, have been showing great support for WebRTC.

How does WebRTC work?

The framework is based on HTML5 and JavaScript but does not utilise SIP or H.323 like other Unified Communication solutions. The signalling and transfer of data works over RTP and with an XMPP extension called “Jingle”. With the newly introduced JavaScript Session Establishment Protocol (JSEP) direct connections can be established without the need of a piece of hardware in the middle. Depending on the deployment audio, video and / or other data can now be exchanged to allow WebRTC to happen in your browser.

And for our firewall traversal specialists: WebRTC can do STUN, ICE, TURN, RTP-over-TCP and supports proxies. What else do you wish for?

What does WebRTC mean to me?

Imagine the impact of 1,000,000,000+ endpoints. Not bad! This is the potential amount of endpoints talking to each other and making VoIP calls or even video conferences. Even though Microsoft is strongly pushing Skype for desktop video conferencing, they are also making sure that their Internet Explorer is ready to take on the WebRTC challenge.

But the missing link right now is: Will there be interoperability between WebRTC and other Unified Communication solutions? I believe the first developers, making both worlds compatible to each other will have edge.

Examples for WebRTC?

The possibilities are impossible to count. Especially in the age of BYOD everyone has their smartphone always ready and beyond that every notebook and desktop PC could participate in WebRTC. Here are some examples I could think of:

  • Customer service via video conference (the end of the service hotline?)
  • Working together on documents via web (web-collaboration beyond firewalls)
  • Smart-TVs allow you do do video conferences without infrastructure or service running in the back (if there’s a browser – there’s a way!)
  • Not interested in video conferences? Have a video diary! (takes only cloud storage and WebRTC)
  • WebRTC might change the face of Social Media platforms like Facebook, LinkedIn and Twitter completely if implemented (why not quickly talk about it?)
  • Instead of displaying phone numbers to your common window-shopper, provide a QR-code or a NFC space, so users can reach directly to you with their smartphone or tablet (we got a camera, a mic, a speaker – so let’s use them!)

Is there a WebRTC presentation?

You are lucky! Google has recently released a web-based presentation with a lot of interesting slides. I have also added a video below, for your to get some more details on WebRTC, Let me know of your thoughts!

Personal Telepresence – Software Solution Comparison

Telepresence on your desk is a great enhancement to the benefits of video collaboration. It enables you to join meetings ad-hoc and (at least for me) replaced the need for doing a phone call. Even if hardware based endpoints are not available there are software solutions available for personal telepresence.

Throughout 2012 I have been using a hardware-based endpoint for quick communication via video and since January 2013 I switched to a software-based solution. I tried out a few and wanted to share the comparison with you.

In the personal telepresence solution comparison below, I listed several options on personal telepresence software clients or web conferencing solutions with video conferencing functions. You will also find links to each solution further down, in case you would like to get more details on the products.

My requirements

In the comparison we considered most features and functions but to keep it short and sweet, we published only the most popular and relevant ones. For myself I have a strong focus on security and encryption as well as the ability to call all other H.323 based endpoints and infrastructure devices. With the Videoconference24 client for example I am able to call any box no matter if it is from Huawei, LifeSize, Cisco, Radvision / Avaya, Polycom or similar manufacturers. As long a software-client supports standard SIP or H.323 calling those is also possible – you get the idea: I want to reach them all and I want my line secure even through public internet!

Beside that I enjoy the ability to invite for multipoint video conferences without reserving resources on a separate MCU. In most cases this would cost money yet again and like this I can completely cut both the invest in MCUs as well as starting a video call for right now, without booking nor calling anyone to prepare my conference. Of course video conferencing managed services do make sense in many occasions but just for a sudden meeting I don’t need someone on top of things.

Participants of comparison:

There are more solutions than that available and if you would like to add the solution you have good experiences in please feel welcome to let us know in the comment section below. As usually I am more than happy to update the comparison in collaboration with you.

Summary

I am now using the Videoconference24 solution provided by Global Media Services and don’t have a broken heart when I think back to my hardware-based endpoint from last year. Just one thing I would like to add is that when you are saving big-time money going to software-based solutions: Get high-end peripherals for it! You don’t want to be the VGA person in a HD call because you are using the old webcam back from the days. Recommended gear (in my books) comes from makers such as Logitech and Jabra.

What are you using? And … are you happy with it? I want to know your opinion!

Have An Ultimate Experience With The LifeSize Icon Video Conferencing System

They are out: Check out the new LifeSize Icon series video conferencing endpoints!

Gone are those days, when business was concentrated at a single location. This era witnesses the spread out of business, globally. Many businesses have their bases in in numerous countries of the world or in many cities across a country, so it is not possible to monitor the production team or any other unit of a company by making a physical presence. This calls for the extensively emerging need of ‘video conferencing’, which makes it easier for the business heads to visit all the units or conduct meetings worldwide, and finally, enjoy supper with the family. Doesn’t it feel contended? Of course, it does!

Like it or not! Video conferencing is on a fast transitional phase. Now, it is about the best quality to have best business meetings. Companies are looking out for systems that provide seamless experience, which is easy to use, efficient and budget friendly.

Bearing all the factors in mind, LifeSize has come up with a newly designed system – the Icon series. LifeSize, a division of Logitech, has introduced this system that not only eliminates the cost, but also renders a system that can be used on the go, as soon as the system is installed, without any substantial training.

Colin Buechler, CEO of LifeSize, motioned that the interface of this system is easy to handle, as it doesn’t have too many buttons, to make the system complex to handle. According to him, cost and the system complexity are the two major reasons for any company to be away from the adoption of a video conferencing system and LifeSize has taken care of these factors, while developing its system.

According to LifeSize, Icon Series can be deployed with LifeSize UVC applications that make video conferencing more efficient and flexible. When a video conference is a concern, there are two major factors that are taken into consideration—image and audio quality. So, here is certain in-depth information regarding these two qualities:

High Definition Image

LifeSize cameras provide high definition image, with a wide angle of 70 degrees. The camera lens is empowered by up to 10x optical zoom. The camera supports the highest video performance available and delivers flawless 1080p60 for ultimate clarity and fluid motion.

High Definition Audio

High definition image doesn’t suffice the need of an efficient video conference, it requires having an echo free audio too. The built LifeSize Digital MicPod in the Icon series systems delivers a great feel of Telepresence , as it has an omnidirectional microphone with strong audio processing and delivering capability. Also, if you want to have a standalone environment, you can soon integrate LifeSize touch-screen phone into the system.

Now how much is that?

What are you waiting for? LifeSize Icon series has already arrived and is available at a starting price of 2,999 USD (depending on your region and selected features). Check out their homepage for more information and request a demo!
