High Definition Video Switching; Operator Conference; Video Resolutions - Polycom RMX 2000 Getting Started Manual

Chapter 1-System Overview

Video Resolutions

1-6
• 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

High Definition Video Switching

In High Definition Video Switching (HD VSW) mode all participants see
the same video picture (full screen). Only one CIF video resource is used
for each connection.
HD VSW mode conferencing is defined by:
• Conference Line Rate setting in the conference profile
— All endpoints must connect to the conference at the same Line
Rate. Line rates range from 384kbp to 6Mb. The RMX will always
connect participants at the highest possible video quality the is
supported by the conference Line Rate.
• Endpoint capabilities
— Compliant endpoints can connect to conferences at resolutions of
up to 1920 x 1080 pixels (1080p).
The video quality for the conference is determined by the Highest Common
Mechanism and is based on the endpoint with the lowest capabilities that
is connected to the conference. The Highest Common Mechanism enables
the system to dynamically select the best video quality as endpoints
connect to and disconnect from the conference.

Operator Conference

In Continuous Presence mode, a special conference that enables the RMX
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.
