Chapter 1-Conference Profiles

Video Clarity - Video Clarity feature applies video enhancing algorithms to incoming video streams of resolutions up to and including SD.

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 2-3.

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+ Mode) at bit rates ranging from 1024 Kbps to 4 Mbps (6 Mbps with HD VSW). For more information, see "Video Resolutions in CP” on page 2-3.

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 both MPM and MPM+ Card Configuration Modes. For more information, see Chapter 7, “Operator Assistance & Participant Move” on page 7-1.
