Polycom RealPresence Collaboration Server (RMX) 1500/2000/4000 Administrator’s Guide

The creation of a new H.263 4CIF slide is supported in the IVR Service in addition to the current H.263 IVR slide. If users utilize the default Polycom slides that are delivered with RMX 1500/2000/4000, the slide’s resolution will be as defined in the profile, i.e. SD, HD, CIF, etc.

For more information see “High Resolution Slides” on page 17-16.

H.263 4CIF Guidelines

•H.263 4CIF is supported with H.323, SIP and ISDN connection endpoints.

•H.263 4CIF is supported in CP mode only.

•Click & View is supported in H.263 4CIF.

•AES encryption is supported with H.263 4CIF.

•H.263 4CIF is supported in recording by the RSS2000 and other recording devices.

•All video layouts are supported in H.263 4CIF, except 1x1 layout. In a 1x1 layout, the resolution will be CIF.

•For information about Resource Usage see Table 21-5 on page 21-8.

•H.239 is supported in H.263 4CIF and is based on the same bandwidth decision matrix as for HD.

The CP Resolution Decision Matrix

All the CP resolution options and settings are based on a decision matrix which matches video resolutions to connection line rates, with the aim of providing the best balance between resource usage and video quality at any given line rate.

The following factors affect the decision matrices:

•The Media cards installed in the system affect the number of video resources used for each video resolution and frame rate, the supported video protocols and the maximum resolution that can be used by the RMX. For example, 1080p 30fps resolution is supported only with MPM+ and MPMx media cards and not by MPM cards.

•The used video protocol: H.264 base Profile or H.264 High Profile. The H.264 High Profile maintains the Video quality at bit rates that are up to 50% lower than previously required. For example, a 512 kbps call will have the video quality of a 1Mbps HD call while a 1Mbps HD call has higher video quality at the same (1Mbps) bit rate.

H.264 High Profile is supported only by MPMx media cards.

•A different decision matrix is used for Motion and Sharpness as the quality requirements are different.

By default, the system shipped with three pre-defined settings of the decision matrix for H.264 Base Profile and three pre-defined settings of the decision matrix for H.264 High Profile with Motion and Sharpness video quality for each:

•Resource-Quality Balanced (default)

A balance between video quality and resource usage. This is the only available resolution configuration in version 6.0.x and earlier.

•Resource Optimized

System resource usage is optimized by allowing high resolution connections only at high line rates and may result in lower video resolutions (in comparison to other resolution configurations) for some line rates. This option allows to save MCU resources and increase the number of participant connections.
