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

The IMTC’s SuperOp! event is just across the corner, and this time, I am proud to say that RADVISION will be hosting it (pdf). Companies coming to this event will be testing their products for interoperability. There are parts of the market though, that are ignoring interoperability. From my own experience, they pay dearly for it in due time. Interoperability can be viewed as a process where you hurtle your product against a product of a different vendor and

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

I read a while ago an opinion stating that there is no need anymore for standards - people choose their proprietary way of communication by installing a given application on their desktop or mobile device - be it Skype or one of the other services out there. I disagree with this view. Proprietary solutions definitely have room in our world. If you take telecommunication, the first thing that comes to mind is Skype. They are based on a proprietary protocol,
