(Modified for Quicktime Player 7)
You must use Quicktime Player Version 7.
Please confirm that you have the correct version installed.
We are using Apple Quicktime Streaming to play the conference presentations. The web pages are using embedded video windows with the Quicktime Plug-in. The streaming technology uses industry standard RTSP/RTP streaming so that you can watch the movie without having to download it to your computer. In essence, packets are played shortly after they are delivered rather than being stored in a file on your disk.
People playing this material might run into two problems: 1) the plug-in does not connect to the server and 2) the plug-in connects and begins to play sound but no video. Likely solutions to these two problems are described in the following two sections.
RTSP/RTP streaming works exceptionally well unless your computer is behind a firewall or "network address translation" (NAT) box. In this case you need to use what is called HTTP Streaming. With previous versions of the Quicktime Player you had to specify explicitly which streaming you wanted to use. The new release of QtPlayer, which is Version 7.0.3, will work correctly if you specify "automatic" in the "Plug-in Settings/Advanced/Streaming Transport" preference.
The webpages will automatically select TCP streaming so the media should play whether your directly connected to the Internet or you are connected through a router with network address translation (NAT) enabled.
We have used different video codecs for the material. The source material was captured using an MPEG4 codec, but the the smaller versions we are publishing use the recently released H.264 video codec. Consequently, you need Quicktime 7 to play these videos. Apple has released a version of Quicktime 7, which you can download, for both Mac OSX and Windows. Notice that the Windows version is a preview release. I have had no problems with this version since I installed it on W2K, and the H.264 codec is noticibly better than other codecs at particular bitrates.
