The worldwide enterprise videoconferencing market grew 20.6% year-over-year to approximately $2.7bn in revenue in 2011, according to the International Data Corporation (IDC) Worldwide Enterprise Videoconferencing and Telepresence 2012-2016 Forecast.

The growth in the revenue was driven by well-defined video use cases across a variety of vertical market business segments, and the continuing decrease of cultural barriers to video acceptance within organisations.

IDC expects that the worldwide enterprise video market will grow to almost $3.2bn in total revenue in 2012, achieving a growth of 18.7% compared to 2011.

IDC Enterprise Communications Infrastructure senior research analyst Rich Costello said they also expect to see increasing integrations of video and telepresence with unified communications and collaboration (UC&C) applications driving the market during the 2012-16 forecast period.

A growth of 22.4% to $716m in total revenue has been seen in the total worldwide enterprise video infrastructure equipment market in 2011, which includes revenue from MCUs, gateways, video network servers and appliances, and other related video network equipment, IDC said.

Worldwide immersive telepresence revenue, which the high-cost, high-end HD segment of the enterprise video and telepresence spectrum, was $315m in 2011, a 22% decrease compared to 2010.
