EXECUTIVE SUMMARY

The Radvision XT5000 high definition conferencing system is designed to be installed either permanently in a small to medium sized conference room or as part of a Roll-about unit.

The basic system supports two HD channels: The main channel at 1920 x 1080 pixels /50fps (default for UK users) and the presentation channel at 1920 x 1080 /60fps. The main channel frame rate may be increased to 60fps via the configuration menu. A high definition (HD) camera, a table microphone pod, an infra-red remote control and PC connectivity completes the package.  Several options are also available:

1. A four or nine site on-board Multipoint Conference Unit (MCU)
2. 12 Mbit/s Extended IP Bit Rate
3. Additional Digital Microphone Array Pod
4. Advanced Audio CODEC pack (G.728 and G.729A)
5. Support for Scopia desktop and mobile

The maximum point to point connection speed is 6 Mbit/s, the 12 Mbit/s Extended IP Bit Rate option extends the total MCU call bandwidth to 12 Mbit/s but individual connections are still restricted to 6 Mbit/s.

Compatibility with other H.323 CODECS is achieved across a range of resolutions from SIF (352x240) to 1920x1080 pixels. The quality of the conference is dependent upon the capability of the remote CODEC and the connection speed.

Pros:

• Feature rich, compact and easy to install.
• Up to 1080p @ 60fps on the main video channel and 1920 x 1080 pixels @ 60fps on the H.239 presentation channel.
• 12 Mbit/s overall MCU bandwidth.

Cons:

• Camera Performance.
• Only two images from: Near, Far and Presentation available in single monitor mode
• Limited web video monitoring facilities.
