Danny Loeb provided his insights on the effect of multicore on SIP servers, but what about video communication clients? Up until today, there is a tendency to either push multi-core hardware as the next best thing (mainly by the relevant chipset vendors) or to dismiss it for most uses. While that has been true up until today, it’s popularity is changing - the latest evidence being Skype version 4.0 beta release, which is video-centric. There is a multitude of other

This post is better suited for our Video Over Enterprise blog, but this should be a good lesson to all of us in the VoIP market. For the past several years, our company has been investing in VoIP infrastructure. Today, I am capable of making video calls and joining audio and video conferences from practically everywhere - from meeting rooms to my work station, my laptop and even my mobile handset. Or as Sagee would say - “The shoe-maker does

iPhone 3G is not out. As I have predicted, it doesn’t include any video conferencing technology. Instead of starting to analyze and explain what this new version is going to do to the market, I’d like to step back and look at what the first iPhone already did. Simply put, the iPhone has placed the ODMs and the handset vendors in a UI-frenzy.The iPhone came out as an innovative handset. Apple boldly decided not to try and compete in the

Two weeks ago, RADVISION hosted the IMTC SuperOp! 2008 event. The most obvious conclusion from this event is that multimedia conferencing (or should I say Unified Communications) is getting better – at least in terms of interoperability. Without exceptions, all companies successfully connected video sessions with one another. The IMTC SuperOp! event is the main interoperability event of the IMTC. In this event multiple activity groups, each dealing with a different multimedia communications technology, gather in a single room to

[The ITU have started working on a standard called the Advanced Multimedia System, or AMS. It is a communications protocol intended to solve some of the issues that plague today’s protocols and also enable functionality that is not easily achievable with current systems. I have asked Paul Jones, the rapporteur for the AMS expert group to provide some of his insights on this “standard under construction.”]One of the exciting things about the technology industry is that technology is constantly changing

Testing a video telephony system has a lot of aspects. One of the most important ones is the resulting video quality of the system. Problem is, there’s no easy way of doing that. Two approaches exist today for video quality testing: Testing against a known video reference Testing the video without any reference 1. Testing against a known video reference If we receive a video stream that is known in advance, we can

There is a growing trend that is placing video conferencing endpoint vendors on a collision course with LCD makers: In recent years, endpoint vendors have started to provide high-end video conferencing clients built into LCD monitors to executives. As technology becomes cheaper, they will start providing these monitors to all employees - not only to executives. On the other end, the LCD vendors are facing fierce competition with ever-shrinking margins. This competition has forced these vendors to search after added

Video as a means of communication between people has been with us for over a decade, but it hadn’t made it mainstream yet. It seems like there is evidence of that changing.Technology wise, we are almost there: We now have the processing power, bandwidth and knowledge of how to build a video system enabling people to interact in real-time and provide good quality of experience. Only problem is, video telephony is not taking off as much as it should, but
