Provided answer is correct -By enabling 802.11n data rates and providing packet error correction, multicast-to-unicast capabilities of Cisco VideoStream enhance the reliability of delivering streaming video over Wi- Fi beyond best-effort features of traditional wireless networks. https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-1/VideoStream/b_Cisco_Unified_Wireless_Network_Solution_VideoStream_Deployment_Guide.html

VideoStream VideoStream provides efficient bandwidth utilization by removing the need to broadcast multicast packets to all WLANs on the AP regardless if there is a client joined to a multicast group. In order to get around this limitation, the AP has to send multicast traffic to the host using Unicast forwarding, only on the WLAN that the client is joined and at the data rate the client is joined at. VideoStream can be enabled globally on the controller. The feature can also be enabled at the WLAN level, and provides more control to the administrator to identify specific video streams for Multicast Direct functionality.
