Executive Summary Radvision XT5000
Evaluation carried out December 2012
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:
- A four or nine site on-board Multipoint Conference Unit (MCU)
- 12 Mbit/s Extended IP Bit Rate
- Additional Digital Microphone Array Pod
- Advanced Audio CODEC pack (G.728 and G.729A)
- 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.
