Avc-Based Video Session Types; Dynamic Continuous Presence; Operator Conference; Avc-Based Video Resolutions - Polycom RealPresence Getting Started Manual

In the same way, the MCU processes the video streams received from the SVC participants,
converts them into AVC video and then transcodes all the video streams to compose the
video layout that is sent to the AVC endpoints.

AVC-based Video Session Types

All endpoints have AVC capabilities and can connect to AVC conferences running on the
MCU. AVC-based endpoints can connect using different signaling protocols and different
video protocols.

Dynamic Continuous Presence

The dynamic Continuous Presence (CP) capability of the Collaboration Server system
enables viewing flexibility by offering multiple viewing options and window layouts for
video conferencing. By default every conference, Entry Queue and Meeting Room has the
ability to declare the maximum CP resolution as defined for the system. This includes
conferences launched by the Collaboration Server Web Client and conferences started via the
API.
For more details, see Polycom® RealPresence Collaboration Server 800s Administrator's Guide,
"Continuous Presence (CP) Conferencing" on page 2-4.
Video Layouts in CP
A selection of layouts are available to accommodate different numbers of participants and
conference settings.
Multiple Switching Modes
If the number of participants is higher than the number of video windows in the selected
layout, switching between video participants can be performed in one of these modes:
•
•
•
•

Operator Conference

In Continuous Presence conferencing, a special conference that enables the MCU user,
acting as an operator, to assist participants without disturbing ongoing conferences and
without being heard by other conference participants. The operator can move a participant
from an Entry Queue or ongoing conference to a private, one-on-one conversation in the
Operator conference. For more details, see Polycom® RealPresence Collaboration Server 800s
Administrator's Guide, "Operator Conferences" on page 10-1.

AVC-based Video Resolutions

Resolution Configuration for AVC-based CP Conferences

The Resolution Configuration dialog box enables the Collaboration Server administrators to
modify the video resolution decision matrix, effectively creating their own decision matrix.
The minimum threshold line rates at which endpoints are connected at the various video
resolutions can be optimized by adjusting the resolution sliders.

Voice activation (default mode)
The Collaboration Server user forces participants to selected video window
Lecture Mode - The lecturer is viewed in full screen by all conference participants, while
the audience is "time-switched" in the speaker's view
Presentation Mode - When the speaker's presentation extends beyond a predefined time,
he/she becomes the current lecturer and the conference switches to Lecture Mode
