Explanation:
Binary Floor Control Protocol (BFCP) is a Cisco Jabber Video for TelePresence media stream that uses only
one User Datagram Protocol (UDP) link. BFCP is a content-sharing protocol that uses a separate content
channel to enable endpoints to display presentation materials and participants simultaneously.
Each of the other media streams requires two links: one for Real-time Transport Protocol (RTP) and one for
RTP Control Protocol (RTCP). The secondary video stream is used for presentation sharing. Far-end camera
control (FECC) is used to pan, tilt, and zoom remote cameras.
