Apple’s FaceTime is now a fact. And by the success Apple had with the iPod and in recent years the iPhone, it is bound to change the market – maybe not the end users one, but definitely the handset vendors, who by now are looking for their own solutions to this problem. I’ve seen a bunch of webinars, whitepapers and other articles about how FaceTime-like services can be integrated by other handset vendors. Usually, these resources focus on a single

Last week I attended a technology event dedicated to embedded solutions. In one of the sessions, a company focused on operating system abstraction layers (OSAL) presented their take on porting. To make a long story short, the hour was devoted to showing how porting becomes a breeze for customers using their product to the extreme – you just “use the product” and voila – no need to think about porting ever again. As someone who’s done his share of porting

We’ve just officially announced our BEE client framework solutions, a broad family of multi-protocol, multi-platform VoIP products. While we have advocated in the past for multi-protocol clients, I think we’ve taken it a step further. Not only do we offer multi-protocol support, we now offer it over multiple platforms in quite a unique manner. Last week, I had 2 meetings back-to-back, in the middle of the night (at least here in Israel, as both were with the west coast) about

There’s a trend these days to employ Forward Error Correction (FEC) as a means to improve media quality in voice and video calls. It is also something that RADVISION has been actively pushing at the ITU-T – and will probably be added in one of the next ITU-T meetings as H.323 Annex I. When we started working on our SVC solution, and had to decide where to place the error correction data, we debated on a very basic question:

This post is part of our Designing Hardware for HD series. Be sure to check it out! [While I've done my best to cover the various options for HD video chips and the trends in the market, I also wanted to take a deeper dive and explain how we analyze such a chip. In this case, the TI DM6467, which we have selected as the basis for our BEEHD product. For that, I asked Amit Klir, our resident video architecture

[This post is taking part in our Designing Hardware for HD series. Be sure to check it out!] Last week I too k the time to map the different options of video coding chip solutions. There is one thing I left out, although it can be deduced from that post, and that’s the trends that exist in the video coding chip market. As a quick recap, there are two main groups of solutions for video coding chips – those that

[This post is taking part in our Designing Hardware for HD series. Be sure to check it out!] One of the most burning issues involved with designing a video telephony device is where the video codec is going to reside. The reason is that this is by far the most CPU intensive task of the whole system, especially when going up to high definition. I’d like to discuss the various options that exist today on the market, with their relative

[Matan Barth is a Project Manager in our Global Services group. Since he is working on several projects that deal with IP PBX technologies, I've asked him to provide his views on this subject. As a result he'll be posting a series of posts on media relay. This is the first installment in the series.] To relay or not to relay – to paraphrase Shakespeare - is a decision that may well be as important as “to be or not

[We've just announced our Samsung-RADVISION VC240 HD videoconferencing LCD monitor and our BEEHD videophone engine. What we've noticed is that customers tend to ask a lot about our video codec in these products. Amit Klir, our "resident media specialist" for BEEHD explains what makes the video codec in our client product so great] As when giving a gift, customizing it makes the gift so much more effective: the same hold true with video codecs. When looking for one, you need
