About the Cisco MeetingPlace Video-Conferencing Process
How Video Conferences Run About the Video Images
The visual stream to and from the vid eo endpoints is entirely processed by the Cisc o IPVC MCU. After
the call is connected, the media stream is routed from the video endpoint, through the CiscoIPVC MCU
for processing into a unified video stream, and back to the video endpoints for display to the users.
However, users control the status of the transmission (for example, started, paused, or terminated) from
within the Cisco MeetingPlace web-conferenci ng meeting room. See About Displaying the Status and
Options of Video Participants in the Meeting Room, page 2-8.
About the Audio Channel
The audio streams of the Cisco IPVC MCU and Cisco MeetingPlace a re mixed to allow audio and
video-conferencing participants to hear and speak to each other. The audio channel fro m each video
endpoint is routed to the Cisco IPVC MCU, then passed through the video link to the
Cisco MeetingPlace audio server, where it is mixed with the audio fr om audio-only endpoints and sent
back to all users, to form a seamless audio experience for participants on both video and audio-only
endpoints.
About Displaying the Status and Options of Video Participants in the Meeting Room When the Cisco IPVC MCU admits a participant to a video conference, the CiscoIPVC MCU notifies
Cisco MeetingPlace Video Integration, which notifies Cisco MeetingPlace Web Conferencing.
Cisco MeetingPlace Web Conferencing identifies the participant as a video participant in the participant
list in the Cisco MeetingPlace web-conferencing me eting room. The participant name displayed comes
from the participant’s profile or guest information if they outdialed from Cisco MeetingPlace, and from
the gatekeeper if they dialed in to the video conference. When a participant mutes, pauses, changes the
view of, or terminates their video connection, Cisc o MeetingPlace Web Conferencing registers this
change in the meeting room user interface and passes the request to
Cisco MeetingPlace VideoIntegration, which passes the request to the Cisco IPVC MCU where it is
performed. If the user terminates the connection by hanging up the vi deo endpoint, the
Cisco IPVC MCU notifies Cisco MeetingPlace VideoIntegration, which then notifies
Cisco MeetingPlace Web Conferencing so that the status of that participant can be updated.
When a video participant speaks, the Now Speaking display shows “Video Participant.”
How Cisco MeetingPlace Video Integration Tracks Port AvailabilityThe number of available ports and conferences is determined by the Cisco IPVC MCU.
Cisco MeetingPlace Video Integration polls the Cisco IPVC MCU every 30 minutes for this information
and passes it to the Cisco MeetingPlace audio server, which displays it in MeetingTime.
Cisco MeetingPlace Video Integration uses this information to regulate the creation of and entry to video
conferences.
