• Video Clarity - Video Clarity feature applies video enhancing
algorithms to incoming video streams of resolutions up to and
including SD.
• Operator Conferences - Offers additional conference management
capabilities to the RMX users, enabling them to attend to participants
with special requirements and acquire participant details for billing
and statistics. This service is designed usually for large conferences
that require the personal touch. Operator assistance is available in
MPM, MPM+ and MPMx Card Configuration Modes. For more
information, see Chapter 8, "Operator Assistance & Participant Move"
on page 8-1.
From Version 7.1, MPM media cards are not supported.
• Supported resolutions:
— H.261 CIF/QCIF – Is supported in Continuous Presence (CP)
conferences at resolutions of 288 x 352 pixels (CIF) and
144 x 176 pixels (QCIF). Both resolutions are supported at frame
rates of up to 30 frames per second.
— 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 2-4.
— 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 2-4.
