I’ve been writing about or simply mentioning High Definition in almost every post here, so excuse me for not telling (again) the HD story or explaining (again) why it’s worth your every cent. I have already discussed the definition of “high”, and reached the following lower limits: Display resolution of 720p 25 frames per second Bitrate of 1 Mbps The evolutionary steps of video conferencing that introduced us to HD were quite dramatic: in two

Last week Tsahi wrote a funny post on what Twitter would look like if Microsoft was behind it. Well, I thought to myself – I love Twitter, I love video conferencing – how about writing my own twist on Tsahi’s post, and try to imagine how video conferencing would look if it was built by the Twitter folks… Video Conferencing would be given a much cooler name. Viddo? Confr? Each speaker would be limited to 140 words. After 140

“Sometimes we spend more time than we should defending the old thing, instead of working to take advantage of the new thing.” ~ Seth Godin. A while ago I wrote a post about the sisyphic nature of our work, where generations come and go but the market demand remains forever. My bottom line was that as there is never enough processing power, you should always be planning your next generation. “Next generation” in Hebrew is “Ha-Dor Ha-Ba”, and so when

In the video processing world we are all performance chasers. Just like “ambulance chasers” us video processing guys are making a living from victims of disasters, applications that needed video but couldn’t afford it, applications that thought there is “too much processing power“. On one hand, the world went from SD to HD in just a few months, and suddenly the bigger the better. On the other hand, Tsahi has already discussed how CPUs today fail to deliver in terms

There are tons of collaboration tools out there. Lots of them support video. There isn’t a clear “best” or “better” solution, as it all depends on needs and communication characteristics. And yet, if I were an enterprise, big or small, looking for a collaboration tool, there are a few things I would look for, guidelines I would follow. I call them my 10 commandments for collaboration software: I. I am Standard-based While proprietary solutions can promise (and even deliver) cool

“Generations come and generations go, but the earth remains forever…” (Ecclesiastes 1) In almost every other post in this blog, and maybe in any tech blog, in salesmen’s pitches, the news, magazines and commercials – it’s High Definition this, High Definition that. And ever since LifeSize announced the first ever High Definition endpoint in December 2005, the video conferencing market has gone HD-loony with “high definition” becoming a must-phrase in every discussion. Q: So what, really, is High Definition

I have been talking and writing a lot about Video Conferencing since I started working for RADVISION. I have to admit, in the past I wasn’t sure what form would the personal video conferencing endpoint have, but lately the answer is literally right in front of you: Desktop Video Conferencing. If you haven’t heard, Desktop Video Conferencing is happening, and although there is always room for more innovation, the recent release of Scopia Desktop, RADVISION’s desktop video client, is promising

The Human Race 10K banner. (CC) On the last (Sun)day of August I participated in a one of the most amazing world-wide sporting events/marketing campaigns I have ever experienced – the Nike Human Race 10K. In case you hadn’t heard: on August 31 almost 1 million runners, in 27 locations around the world, from China to Australia, including myself and 10,000 others in Tel Aviv, ran 10 kilometers. This was a truly thrilling experience, and not just because I

[This post is based on a lecture given by Ariel David and I on the effects of IP networks on visual quality in video over IP applications] One of the biggest obstacles of the video conferencing industry has long been the user experience. Early video conferencing systems suffered from poor quality video and low fidelity audio, as well as great difficulties in establishing and maintaining connection for the conference duration. Most of these issues were solved with advances in processor
