Sometimes people use the expression “timing is everything” very loosely, but when it comes to real time video communication, this colloquialism rings true. It is both irritating and frustrating when you are trying to have a meaningful exchange with someone and you end up with pregnant pauses between the time that you say something and the other end receives it. The results: frequent air-time collisions and lip sync so bad you feel like you’re conversing with a ventriloquist. This delay between transmit and receive is known as latency.
Latency has long been one of the most significant factors inhibiting video conferencing adoption. Those who struggled through it, did so for years because there were no alternatives. There are several contributing factors to the “glass to glass” latency in a video conferencing system, including network traversal, endpoint encode and decode, and, the greatest source of latency, the transcoding MCU. Now, however, with the arrival of a new class of solutions that have eliminated the need for transcoding, including Vidyo’s personal telepresence, end users have options and are beginning to demand more natural interactions from their visual communications experiences.
At the Visual Communications Industry Group’s first annual conference in Ft. Lauderdale, FL this week, Bob Dixon of the Ohio Academic Resources Network and Ben Fineman of Internet 2 hosted a session on Desktop Collaboration Tools. Vidyo and three other vendors were invited to participate in the session to provide a live demonstration of their desktop solution, have a couple customers join via their tool to talk about their use cases, and give a brief presentation regarding the solution.
Tandberg withdrew from the event citing that they wouldn’t have anyone in the area to do it… When Polycom gave their demonstration and presentation. Latency. Like Tandberg their dependency on the transcoding MCU for multipoint conferences puts them at a disadvantage in terms of performance.
Users in the audience, after suffering through the latency issue for years, were quick to identify it and were effectively demanding a higher quality solution. In short, they were looking for Vidyo. Happily, they found us on the show floor and in our presentation on scaling video conferencing deployments. And soon, they’ll find us in their network, where their MCU used to be.
