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?

setup, diagram, webrtc, workflow, process, technical, implementation, visual, visualisation, chart, image, picture, explanation, how does webrtc work

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!

Microsoft Lync 2013 – New Feature Overview

microsoft, lync, 2013, im, uc, unified communications, client, screenshot, example

Microsoft Lync 2013 – Main Window

Are you planning to upgrade your unified communications IM client? Following up on the article “What Is Microsoft Lync?” by Mark Stubbles we would like to introduce you today to all new features of Microsoft Lync 2013.

In comparison the Microsoft Office Communicator (also known as OCS) had the look and feel of Windows XP, the Lync 2010 update brought it up to speed with the Windows 7 design and finally Lync 2013 has the looks of the Windows 8 and Office 365 environment. But of course there is much more under the hood than just eye-candy. I listed below a few of the new features that were most interesting to me.

Overview of new features in Lync 2013

Visual Features:

The main window has been optimized to provide better access and a more intuitive using of the application. The new tabbed conversation feature gets rid of having several chat windows open at the same time – so you can keep track of all your conversations in a single place and just have to browse through them. Similar to the tabbed browsing of Google Chrome you are also able to move a certain chat out of the tabbed conversations and provide them with their own window and naturally you can move it back into the tabbed conversation window.

And for everyone who would like to display the images and fonts larger they can easily adjust the display setup in the configuration of the client. This is not only a help to users with sight challenges, but also can be useful for a deployment on wall-mounted displays.

Easier Deployment:

The main Lync 2013 client and the Online Meeting add-in is now included in the setup program of Office 2013 so deployment on the software side has been made significantly easier, especially for large enterprises with many thousands of workstations.

However because this part has changed Microsoft has also changed how the group policy is deployed. Instead of working on the communicator.adm file to define policies, certain ADMX and ADML admin templates are provided along with Office Policy Administrative Templates to work on. For more information on this particular topic I suggest reading the Microsoft article on “Group Policy Settings for Lync 2013“.

BYOD Enhancements:

Microsoft Lync 2013 – Calling a Smartphone

With Lync 2010 the App for smartphone, there was only support for presence and instant messaging while the new Lync 2013 App for smartphones and tablets also supports Voice calls and mobile video conferencing over WiFi and cellular data connection alike. Regardless of the fact that many desk phones can be connected with your Lync client, utilizing Lync on smartphones and Lync on PCs within your organisation your permanently replace the requirement of having a separate hardware phone on your desk and cutting costs for invest and maintenance by enforcing unified communications technology. For a more detailed overview of the features for mobile Lync I recommend the “Mobile Client Comparison Tables” page by Microsoft.

The users accessing from non-corporate workstations via browser also get some good news. The Lync 2013 Web App for web-based conferencing received support for voice and high definition video conferencing devices. Meeting participants can also show their screens for collaboration or presentation and re-assign the presenter role to others – They get the full Lync 2013 meeting experience without having the software client installed on the machine.

Functional Features:

The Lync 2013 client can handle virtual environment better. Virtual Desktop Infrastructure (VDI) fully supports audio and video devices, like a headset and a webcam, to be connected to the client even though you might be using a virtual machine such as a thin client or a differently re-purposed workstation. For more details on how to deploy the Lync VDI plug-in please check the Microsoft TechNet article.

Microsoft Lync 2013 – Chat Room Integration

Another interesting new feature is the chat room integration (also known as persistent chat rooms or topic feeds). In older versions you were already able to create group conversations for multiple users to chat or hold a presentation for instance. In the new Lync 2013 however these can be promoted to be permanent and will be also available for others to be joined, including all the content that was added and when. It might not be applicable to all services and organisations, but this feature might the need for static email lists and adds a new dynamic way of sharing information and making such available for all. If you don’t want it to be available for all users, there is also the option to limit the visibility to certain users or user groups.

Also newly implemented is a feature that lets Lync 2013 automatically assign you with “presenting” status, to block incoming communication unless the sender is in an approved group. If you are a two-screen users however this is not automatically done for you, if you use the secondary screen as presenting space.

You may have made experience with previous versions of the client that you would like to keep a certain conversation up for reference but you need to restart the machine. What happens? The information is gone. In the new Lync 2013 once you are back booted up, the conversation comes back along with the content of the conversation, you held before rebooting. I found this to be quite the time-saver in those moments.

Improvements of already deployed functions:

  • Outlook Meeting Scheduling updated
  • Native Video Conferencing enhanced
  • Web App and Mobile App now support voice and video conferencing
  • Contact and card view was improved
  • Meeting participation functions were heavily improved for better collaboration

Have you tried Lync 2013 out yet? Missed your favourite new feature? I would be delighted to hear your opinion. Drop us your comment below!

Low Budget Telepresence for Your Tablet

Revolve Robotics to turn your tablet into a Telepresence device soon?

Not yet another app but a high-tech tablet stand, that is what the people from Revolve Robotics are introducing to the market and they call it “Kubi”.

Kubi, Telepresence, Revolve Robotics, Video, Conference, Video Conference, Tablet, Stand, Mount, Tripod, Apple, iOS, Android, Google, iPad3, iPad, iPad4, High-tech, High, Tech, nice, Design, Lights, No, Cable, Meeting Room, Meetingroom, Small, Medium, Business, SMB, Home, BYOD, Communication, Enterprise, Unified Communications,

The sleek design and the wide range of possible applications for Kubi allows you to use it as personal Telepresence device for the home office as well as it could provide a low-budget Telepresence solution to small to medium-sized meeting rooms.

Who is Revolve Robotics?

Based in San Francisco (USA), Revolve Robotics was founded earlier this year by Artificial Muscle, Inc. (AMI) founder Marcus Rosenthal and Key System Designer and Product Visionary Ilya Polyakov.

How to get it?

Kubi is currently available for pre-order at indiegogo.com for the price of $199 instead of the targeted retail price of $249. As this is a new product you may also support the Revolve Robotics start-up and the Kubi tablet stand on the very same web page.

What can it be used with?

Kubi is designed and tested to work with the Apple tablet line-up (e.g. iPad3, iPad4 and iPad mini) but it is said to be basically compatible with every device that supports Bluetooth 4.0 as well. An iOS app is currently on the way as per developers and an Android solution is planned to be completed in the future as well.

Technically this would include newer smartphones as well, however the current Kubi model does not have arms small enough to hold the device properly. Perhaps Revolve Robotics will surprise us in the future with a solution that concentrates entirely on smartphones and similar devices.

How does it look like?

Kubi, Apple, iPad, iPads, iPad1, iPad2, iPad3, iPad4, iPad mini, Sleek, Design, White, Stand,

Summary

Product designs like the Kubi and start-ups like Revolve Robotics indicate that both Telepresence technology as well as BYOD is not just a trend in the market. The applications and the hardware might change but at least two things are clear:

  1. Telepresence (a.k.a. Video Conferencing) is here to stay
  2. Enterprise and consumer technology will continue to merge

That much being said I am looking forward to hear more from Kubi as well as from the start-up company Revolve Robotics and wish them all the best for the release of their high-tech tablet stand.

Nintendo brings Personal Telepresence to your Living Room

Nintendo and Vidyo announced that the new Nintendo Wii U console will support the Telepresence technology from Vidyo. Users will be able to use their Nintendo Wii U now to make video calls to other players. This Telepresence solution was introduced in November under the name “Wii U Chat” (Video attached below).

The scope of service will be first for point-to-point connections only but it perhaps this can be enhanced to a multi-site-call, similar to the Google Hangout, in the future. This is the first step of bringing enterprise grade Telepresence technology into the homes of families and not only into an enterprise boardroom. This is an important step for Vidyo to take and shows again the success and potential of software-based Telepresence solutions as well as the importance of BYOD. We are excited about this news and hope we see new revelations in the market of Telepresence solutions for consumers soon.
