The LifeSize Video Center Version 1.2 software includes a mechanism for automatically changing the bit rate of a stream for certain types of clients when they are detected on the network. Using the right bit rate for the network and device can eliminate the need for buffering, Miller said. Administrators can set up as many as four different bit rates and assign those to particular types of devices based on policies.

This "automatic adaptive streaming," as well as being able to stream to iOS devices, sets LifeSize Video Center apart from other systems in its class, including ones from Polycom and Cisco, Miller said.

Polycom said its Polycom Video Media Center supports multiple video formats, including for mobile devices, for on-demand streaming. The company plans to offer adaptive bit rates for live streaming later this year. Cisco offers automatic transcoding and optimization of streams for a wide range of mobile devices, including the Apple iOS lines, on its higher-end Media Experience Engine appliance.

The updated software is set to become available next month. LifeSize Video Center is available globally for a list price of US$29,999.
