AVC Conferencing Parameters

Basic Conferencing Parameters

When defining a new video Profile, you select the parameters that determine the video display on the participant’s endpoint and the quality of the video. When defining a new conference Profile, the system uses default values for Continuous Presence (CP) standard conferencing. Continuous Presence conferencing enables several participants to be viewed simultaneously and each connected endpoint uses its highest video, audio and data capabilities up to the maximum line rate set for the conference.

The main parameters that define the quality of a video conference are:

•Line (Bit) Rate - The transfer rate of video and audio streams. The higher the line (bit) rate, the better the video quality.

•Audio Algorithm - The audio compression algorithm determines the quality of the conference audio.

•Video protocol, video format, frame rate, annexes, and interlaced video mode - These parameters define the quality of the video images. The RMX will send video at the best possible resolution supported by endpoints regardless of the resolution received from the endpoints.

—When Sharpness is selected as the Video Quality setting in the Conference Profile, the RMX will send 4CIF (H.263) at 15fps instead of CIF (H.264) at 30fps.

—H.264 High Profile protocol provides better compression of video images in line rates lower than 384 Kbps and it will be automatically selected for the endpoint if it supports H.264 High Profile. If the endpoint does not support H.264 High Profile, the RMX will try H.264 Base Profile which provides good compression of video images in line rates lower than 384 Kbps (better than H.263 and not as good as H.264 High Profile).

—When working with RMXs at low bit rates (128, 256, or 384Kbps), HDX endpoints will transmit SD15 resolution instead of 2CIF resolution.

When using a full screen (1x1) conference layout, the RMX transmits the same resolution it receives from the endpoint.

•Lost Packet Recovery (LPR) - LPR creates additional packets that contain recovery information used to reconstruct packets that are lost during transmission.
