READING (Done on LifeSize A Leading Member in Video Conferencing)
Its said that Videoconferencing has never taken off in the industry, mostly because of the quality. A creative only has to see his beautiful roughcut butchered over a stuttering video link to walk away from the technology forever. Had the opportunity to finally take a live look at the LifeSize high definition videoconferencing system. In short, the system delivers a 16:9 widescreen 1280x720 pixel image (720p in broadcast parlance) at 30 frames per second with very little artifacts.
By comparison, traditional video conferencing uses CIF resolution which is 352x240. Thanks to Videré, a specialist on video conferencing systems based in Quincy, MA, was able to see it side by side with a traditional videoconferencing rig, and there is no comparison...
The components powering this system are sleek and well designed:
A remote controlled camera more than a little reminiscent of the sleek Apple iSight camera, a slim desktop audioconferencing device, a small tuck-away electronics package.
The system functions as you would expect, a slim remote gives you access to onscreen menus that you use to make calls as well as control the system. The camera has an exceptionally wide field of vision at 70 degrees to produce the widescreen aspect ratio of the image. Videré set up two IP calls, one from a Tandberg system and one from the Lifesize system at the same data rate, 512kbs and the difference was dramatic, not just in the absence of stairstepping, color blooms and other static artifacts, but also in the fluidity of motion, color saturation and general naturalness of the Lifesize image.
There is of course a price to pay for this. The system is slightly more expensive than a Polycomm system for example, though of course, you are getting a High Definition product versus a product that Polycomm will probably end of life soon to move to HD. There are no current universal HD standards so you will only get HD if you are talking to another Lifesize system. You can connect to non-HD systems over IP using h.323 standard but if you want to use dialup you will need an IP to public switched network bridge.
The system consumes a lot of bandwidth delivering full HD at 1.2 megabits more bandwidth than all but the most robust private networks can deliver with Quality of Service protection. You could chance the connection over the Internet, but doubt it would work consistently unless both ends are supplied by the same carrier. The bottom line though is that this is the first system that has a potential for becoming a tru working tool for creative markets.
You can hook up video sources as well as computers output to it and get full motion realtime video like you have never seen before on a videoconference link. Ideally, you would provide both ends of the call, either office to office or office to client as well as the network connectivity that it requires. Pair that with a well designed room with proper lighting and careful training of the staff to manage the systems, and we could come closer to finally being able to substitute much client travel with videoconferencing.
If you are considering video conferencing, Lifesize is a must see.
