Bandwidth, Quality of Service and Cost Rationalization: Deploying Personal Video Conferencing

As is the case with other forms of enterprise communications, video conferencing is valued for its ability to improve productivity and collaboration across geographically dispersed teams. Unlike web or audio conferencing, video conferencing integrates an all-important visual element that boosts enterprise collaboration and increases employee productivity, which, according to Frost & Sullivan, has been driving wider video conferencing adoption. Even more valuable of a collaboration tool has been the introduction of personal video conferencing via desktop and mobile devices. In lieu of often cumbersome room conferencing solutions, employees are able to host and attend virtual conferences with video on an individual basis and with minimal additional equipment (a simple webcam is needed, which today is often built into desktop computers, laptops, tablets and other mobile devices). While the attractive Software-as-a-Service model continues to gain traction among CIOs in implementing personal video conferencing services, network and quality-of-service concerns arise when considering tens to hundreds to thousands of employees all video calling at the same time.


Until now, the attractiveness of deploying personal video conferencing has been muffled by the economics of installing across-the-board higher quality bandwidth. Unlike web conferencing, desktop sharing or VoIP calling, video conferencing requires a high level of continuous, unbroken connection for the duration of a meeting, which eats bandwidth, costs a lot of money and can negatively affect service quality. Historically, the fix has been to build out a separate overlay network designed to support hefty video performance requirements. This is also expensive and doesn’t eliminate the need for top-of-the-line broadband services.

Business-class-level broadband service with MPLS is usually needed to provide enough connectivity to avoid traffic congestion and ensure video conferencing quality. Upgrading multiple access circuits can increase a company’s broadband costs by thousands of dollars per month. For enterprises wishing to expand personal video conferencing to all employees, this level of additional bandwidth is simply not cost effective.


Personal enterprise telepresence leaders Vidyo have shaken up the video conferencing industry, delivering Adaptive Video Layering: an optimization of video streams based on network characteristics and endpoint capabilities, leveraging H.264 Scalable Video Coding (SVC)-based compression technology and Vidyo’s IP. Each layer’s frame rate, quality and resolution can be adjusted in real-time in response to bandwidth fluctuations, packet loss and/or available CPU resources. In short, Vidyo’s Cloud-based video conferencing platform optimizes video for each endpoint, continuously monitoring network performance and device capabilities. The result is always-fluid video conferencing from desktops and mobile devices over low-cost broadband internet, LTE, 3G or 4G networks, and an enormous shift in the accessibility of personal video conferencing.

The significance of this software is that companies can now easily and cost-effectively benefit from universal video conferencing while slashing the cost of deployment, all by leveraging a converged IP network instead of building out a video-dedicated overlay network. Essentially any connected device with a webcam becomes a virtual meeting endpoint regardless of network capability. Employees thus incorporate video communication into their daily work lives at an unprecedented level, transforming remote interaction, information sharing and collaboration.
