Thanks, Chris Moffatt Lead Program Manager ConferenceXP Project, Microsoft Research chris...@microsoft.com<mailto:chris...@microsoft.com> www.conferencexp.net<http://www.conferencexp.net/> _____ From: Chris Moffatt Sent: Tuesday, November 23, 2004 10:52 AM To: 'cxpannou...@list.research.microsoft.com' Cc: 'presenter-profs-ad...@cs.washington.edu' Subject: Release Candidate for ConferenceXP 3.0 is now available! Dear ConferenceXP User, I'm pleased to report that we are very close to releasing ConferenceXP 3.0 and we'd like to invite you to participate in some real-world testing with the our release candidate. You can download the ConferenceXP 3.0 release candidate here<http://www.conferencexp.net/test/CXPClientSetup30_RC1.msi>. Click here<http://www.conferencexp.net/community/images/cxp30_screenshot.jpg> to view a screenshot. This is a major release, with many enhancements and improvements including: Great support for high quality conferencing: - Controls for audio and video are embedded into the video window to provide a Windows Media-style experience. - ConferenceXP now supports a much wider range of cameras and capture cards. We will post a list of supported devices on the web site. - Support for multiple cameras on a single computer. - We have upgraded our video to the Windows Media 9 codec and also enabled support for "very low quality" (160x120@30fps, 50Kbps) for bandwidth-limited scenarios. - We have improved the usability of the ConferenceXP Client UI. Great Support for wireless, collaborative learning environments: - We have implemented Reed-Solomon Forward Error Correction (FEC) in order to improve the reliability of delivering static data (e.g. slides, ink and navigation over wireless networks) over ConferenceXP's RTP network protocol. - With the 3.0 release, ConferenceXP's peer-peer, multicast architecture, coupled with highly reliable delivery of static data, we are in a position to support large classroom/lecture scenarios where all or many students have tablets or notebooks. - OneNote SP1 is able to receive RTDocument data, and can be used as a client to CXP Presenter and the upcoming v2.0 release Classroom Presenter from University of Washington. (This functionality was included in 2.4.2 but is now exposed in the UI and has undergone testing and bug fixes). - We recently completed a scalability test where we deployed 50 tablets over 802.11b, and were able to deliver slides and ink with greater than 99% reliability, Archive Service and Multicast/Unicast Reflector Service: - The ConferenceXP 3.0 client is enabled to take advantage of our upcoming releases of Archive Service and Multicast Reflector. - The ConferenceXP Archive Service supports record and playback for a ConferenceXP session, including multiple audio/video streams, presentation, and ink. - The ConferenceXP Multicast/Unicast Reflector enables clients running on networks where multicast is not enabled, or not enabled, to participate in a multi-point conference. - We plan to release Beta versions of these services before the end of the year. If you are eager to test these components, let us know and we can direct you to hosted services for testing. Under the covers - RTP/RTCP: We have done extensive work at the network level, and stability and performance has been significantly improved. - RTDocs: We have finalized the interfaces and formats for RTDocs, and look forward to the development of additional collaborative applications. Application Development - ConferenceXP 2.4 was a great platform for collaborative applications and the enhancements and additions to 3.0 have extended the capabilities available to developers. These enhancements include the ability share several capabilities in the same window. - If you're interested in developing collaborative applications on a platform that supports a rich sharing architecture and API, please visit us at http://www.conferencexp.net<http://www.conferencexp.net/> to learn more about how to get involved.
