Supplemental Conferencing Features

In addition to Standard Conferencing the following features can be enabled:
•

— H.263 4CIF - A high video resolution available to H.263 endpoints that are not
H.264 enabled. It is only supported for conferences in which the video quality is set
to sharpness and for lines rates of 384kbps to 1920kbps.
— Standard Definition (SD) - A high quality video protocol which uses the H.264
video algorithm. It enables HD compliant endpoints to connect to Continuous
Presence conferences at resolutions of 720X576 pixels for PAL systems and 720X480
pixels for NTSC systems. Bit rates for SD range from 256Kbps to 2Mbps. For more
information, see "Video Resolutions in CP" on page 2-3.
— High Definition (HD) – HD is an ultra-high quality video resolution. Depending
on the RMX's Card Configuration mode, compliant endpoints are able to connect
to conferences at resolutions ranging from 720p (1280 x 720 pixels) to 1080p (1920 x
1080 pixels) (in MPM+ and MPMx Modes) at bit rates ranging from 1024 Kbps to 4
Mbps (6 Mbps with MPMx). For more information, see "Video Resolutions in CP" on
page 2-3.
H.239 – Allows compliant endpoints to transmit and receive two simultaneous streams
of conference data to enable Content sharing. H.239 is also supported in cascading
conferences. Both H.263 and H.264 Content sharing protocols are supported. If all
endpoints connected to the conference have H.264 capability, Content is shared using
H.264, otherwise Content is shared using H.263.
For more information, see "H.239 / People+Content" on page 2-25.
Lecture Mode – The lecturer is seen by all participants in full screen while the lecturer
views all conference participants in the selected video layout.
For more information, see "Lecture Mode" on page 2-75.
Presentation Mode – When the current speaker's speech exceeds a predefined time (30
seconds), the conference layout automatically changes to full screen, displaying the
current speaker as the conference lecturer on all the participants' endpoints. During this
time the speaker's endpoint displays the previous conference layout. When another
participant starts talking, the Presentation Mode is cancelled and the conference returns
to its predefined video layout. Presentation mode is available with Auto Layout and
Same Layout.
— If the speaker in a video conference is an Audio Only participant, the Presentation
Mode is disabled for that participant.
— Video forcing works in the same way as in Lecture Mode when Presentation Mode
is activated, that is, forcing is only enabled at the conference level, and it only
applies to the video layout viewed by the lecturer.
Telepresence Mode - enables the connection of numerous high definition telepresence
rooms and of different models (such as TPX and RPX) into one conference maintaining
the telepresence experience. This mode is enabled by a special license.
Encryption – Used to enhance media security at conference and participant levels. For
more information, see "Message Overlay" on page 2-45.
Conference Recording - The RMX enables audio and video recording of conferences
using Polycom RSS 2000 recording system.
