Video-based Screen Sharing Support for
Polycom Trio Solution
Polycom Trio 8500 and 8800 allows you to use Video-based Screen Sharing (VbSS) with Skype for
Business clients that enables both application and desktop sharing. In previous releases, Trio systems
supported only Remote Desktop Protocol (RDP) for receiving content. Only systems registered to Skype for
Business support VbSS content sharing.
The advantages of VbSS content sharing over RDP are as follows:
● The video experience is faster, with an improvement in frames-per-second.
● Works better in low bandwidth conditions, even when receiving high motion content, such as 3-D
graphics.
However, if any participant in a Skype for Business conference does not support VbSS, the Skype for
Business server content switches from VbSS to Remote Desktop Protocol (RDP) content.
