An engineer set up video conferencing so that users join the conference by using the Streaming feature on the Cisco Telepresence MCU device Given this setup, which functionality is available to…

Streaming on the Cisco TelePresence MCU is a unidirectional media delivery mechanism; the stream is encoded and sent to viewers who consume it passively. Because participants join as stream consumers rather than full conference participants, they have no bidirectional control channel and therefore cannot send audio, video, or data back to the MCU.

Whiteboard annotation requires an interactive data channel between the endpoint and the MCU, which is not provided to streaming viewers.

The streaming resolution is set and encoded by the MCU; viewers have no control plane connection to request resolution changes.

Layout customization requires a participant to have an active, interactive connection to the MCU conference, which streaming viewers do not have.
