iPhone 3G is by far the most hyped phone (or even product) out there today. Everything about it is great - even though you can’t get coverage, have lousy battery life, buggy OS updates and general instability when you call, the party in the Apple AppStore is going on without a stop, with over 30 million dollars of sales in the first month alone. iPhone iPhone really changed the mobile handsets market. Other than making the concept of downloading applications

Interesting times in the mobile handsets arena. VisionMobile maps the new centers of gravity in this industry. I believe competition will lag behind Apple’s iPhone in their next release as well as copycatting its ideas and designs. Talking about the iPhone - I am thinking of starting a petition to ban iPhone from Google Alerts for 3G video. For the past two weeks I am getting nothing from that service besides iPhone jailbreaks and teardowns. Growing bandwidth and increasing CPU power will change television as we know it. It will also speed up the use of video telephony adoption and quality and this fits well with the trend of multi-core diversification I have written about. You can add to this TiVo’s two new deals with YouTube and Amazon - it’s only the beginning. HD is seen by some as the true promise of VoIP - this is certainly different than the Unified Communications pitch. What happens when you don’t have enough bandwidth though?

There’s no presence in TelePresence. And you know what? There’s also no “unified” or “communication” in UC (Unified Communication). These are just new buzzwords in VoIP town. They are there to replace “video conferencing” and “convergence.” Besides the fact that they are more of the same (maybe better), there’s nothing new under the sun.

Everything today is High Definition (HD). Whether you’re talking about televisions, projectors, video conferencing or even voice calls - the latest and greatest is high-definition capable. That said, high definition is really complex to deal with, not just in terms of bandwidth requirements, but in terms of processing power - especially if we’re dealing with visual communications. The challenge Have you ever tried watching a movie encoded in high definition format on your laptop? Assuming you have a single

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
