Cisco tackles videoconferencing

During the last 15 years billions upon billions of dollars have been invested in research and development relating to videoconferencing.

It was always the "next big thing" in converged IT and Telecoms and would reduce corporate travel bills massively. After 9/11 the videoconferencing industry went through a series of mergers hoping to cash in on a fear of flying but the need to still conduct meetings with remote offices and clients. This has resulted in a leaner industry with more chance of sustaining profitability.

Sadly, despite the successes videoconferencing has had it is stained by the fact the technology has failed more often than it succeeded. So why did Cisco spend two years of R&D time developing their own video-based solution called Telepresence?

The answer is that Cisco sees money. Not just money from customers but money internally. However, rather than try and build a faster, more reliable videoconferencing solution, Cisco has built something a little difference. They call the product Telepresence and it's more about a virtual meeting room than a videoconference. So what is it?

What is Telepresence?

Cisco Telepresence is a room-based solution for virtual meetings, similar to the Halo system that HP is aggressively promoting. It comes as a complete solution with screens, microphones, cameras, lighting, desks and a host of other components that are built into a bespoke room. The screens are 65 inch plasma displays running at high resolution. The microphones have their own noise cancelling codecs developed by Cisco and, we are told, even trap and eliminate the noise and interference of a mobile phone when it is trying to find a signal.

By using such large screens, the person at the far end appears to be actual size rather than scaled down to fit a monitor. The idea is that they look just as they would in a real meeting, were they sitting across the table from you.

The cameras are fixed, not the usual pan, tilt, zoom that you find in videoconferencing and this is important. It means that they have a fixed focal position that can be used to accurately reflect a picture and ensure that the experience is always the same. The back of the unit has its own lighting that is designed to give the cameras the ideal environment in which to work. Each camera is focused on one desk and two people.

Fitting conferencing to a business

There are two versions of the Telepresence system, the entry level 1000 with a single screen and two seats for $79,000 and the 3000 with three screen and six seats for $300,000. Those prices are per room so double it to provide a working point-to-point solution.

When running, Cisco claim that they need as little as 4Mbps per screen and up to 2Mbps for the audio and data traffic. To maintain a high quality image such as Telepresence provides over such modest bandwidth makes this quite remarkable.

In order to use Telepresence you also need Cisco Call Manager v5. This is because Cisco has done away with the plethora of remote controls that most videoconference suits possess and reduced the whole thing to a single button for call setup. Call Manager also allows you to use its scheduling facilities to manage your room.

Another missing element in this cost is the room environmental components. Here Cisco is again being a little careful with their costing. To soundproof a room removing the noise or air conditioning, external noises carried through roof spaces and through cable ducting can be expensive. You have to pay for that on top of the system costs.
