50. Model is based on data from Lync 2013 Preview deployments at Microsoft and TAP customers Video usage (not BW!) doubled compared to Lync 2010 P2P video calls: Heavily depends on user behavior Plenty of resolutions possible from 180p to 1080p ~75% of users with default video resolution of 424x240 ~25% increase video window to obtain 640x360 or HD video

51. MultiView conference video calls: Depends even more on user behavior Typical screen real estate allows for tiles with resolution of 424x240 (clipped to square) Data sharing reduces screen real estate for video in most conferences Not all users actually use video Receive: average of 2.5 video streams Send: average of 1.6 video streams
