…And does it really matter?
- December 2010 – Elisa service on Galaxy- first mobile service offering
by a telecom provider on a tab and phone
- August 2011 – Vidyo’s mobile client is available in the Apple App Store
delivering multipoint HD videoconferencing for both iPhone and iPad
- October 2011 – Polycom announces first enterprise HD video software
solution for tablets
Who was first? Others have called out Polycom for making this false claim. While Vidyo was both first to demo multipoint video conferencing on a mobile device (January 2010 in Paul Otellini’s CES keynote) as well as deliver multi-party videoconferencing on a smartphone and tablet, the real issue for enterprise decision makers is not about who is first, but about who can deliver a complete solution. With the memory of Steve Jobs still in sharp focus, I’m reminded that it is not about a specific product, but about delivering for the user the most satisfying effortless experience.
In videoconferencing, porting an application to run on a device is only a small part of the requirement—this just delivers the potential for a personal video communication device. Having an intuitive UI for entering and interacting within a videoconference is another part of the experience. But the most important aspect is the actual video interaction that makes the communication experience natural and engaging. The challenge is that mobile devices use wireless networks—WiFi, 3G or 4G—and packets will be dropped and bandwidth may be limited as well as highly variable. And, an enterprise quality solution must be capable of multi-party conferences that enable communication with other mobile devices as well as desktop and room system participants who may encode at far higher resolutions.
Delivering on this challenge requires a completely different infrastructure architecture than what is offered by the old market leaders such as Polycom whose MCU architecture was designed for perfect connectivity such as provided by ISDN, and has now developed Band-Aid approaches including Forward Error Correction, Loss Packet Recovery and others to deal with the Wireless.Wild.West non-guaranteed QoS bandwidth. The result is lackluster performance and increased overhead that further exacerbates the challenging network conditions.
And the bad news gets worse for legacy MCU architectures when it comes to multipoint. When you have a mobile device interacting with another mobile device and an HD room system, the MCU transcodes and gives the gift of additional latency. Since it must transcode to enable disparate devices to be in the same multiparty meeting, it degrades the video quality in the process as well as adds delay. The problem is that for a natural interaction to occur on a mobile device, there just is not any time available for transcoding. Sure you can do it, but the experience is no longer satisfying. You’ll speak over each other, develop a tendency to pause before speaking, and other unnatural behaviors that will make you long for just a phone call or in-person meeting. Clearly, not an “Apple-quality” solution.
Vidyo was built with mobile devices in mind. Vidyo pioneered the use of the recent video compression standard—H.264 SVC— in video conferencing because it enables a latency-free way to adapt to packet loss. Vidyo created an architecture that intelligently routes packets to each participant’s device based upon the resolution required, computational capability and bandwidth available, and to do so by dynamically adapting many times a second to changing conditions. And in a multiparty conference, it does this without transcoding so it maintains original video quality and adds less than 10msec delay because it makes packet routing decisions with no need to perform complex computational gymnastics. The user experiences natural HD quality multiparty videoconferencing that is engaging.
While this alone differentiates the Vidyo solution, the win for an enterprise deployment is that the Vidyo infrastructure can be deployed for 10% of the cost of the old Polycom MCU architecture. A single 1U VidyoRouter device can support 100 simultaneous participants. VidyoRouters can be geographically deployed to minimize bandwidth consumption. Since Vidyo is a software solution with central capacity license management, the full pool of licenses is available to all VidyoRouters as needed. The result is a dramatically lower number of licenses required to be purchased. And best of all, Vidyo only needs non-guaranteed QoS networks including internal bandwidth. The cost savings of moving away from dedicated video networks may pay for the entire Vidyo infrastructure!
So maybe this is why Polycom resorts to a misleading announcement. It craves for leadership, but it’s saddled with an old architecture that just can’t.
