This page was created in 1995 to test browsers.
I've added a few things, e.g. flash since then, but have not fixed all the broken links.
See the video page for more.
Most Browsers have built in capability to display plain text, html and inline GIF, PNG and JPEG format images, however they require external viewer/helper applications or plug-ins (see below) for audio, video and other image formats. You can use these examples to verify you have installed and configured your browser to use these viewers. Some types of files cannot be displayed on all platforms.
We also list some other multi-media applications that have become popular on the Internet, but run independently of the Web and don't use Web browsers.
Mosaic categorizes files by MIME types The following lists the file type (e.g. text/plain) and gives the file name extension (e.g.txt) used to signify this type in parenthesis. See Notes on adding Viewers. More information on document types is here.

Streaming Audio/Video How to Listen to Audio at laurable.com and Streaming Media at mbone.com The most common kinds are radio broadcasts; e.g. WHYY NPR in Philadelphia broadcast via: MP3 pointed to with an MPEG playlist [listen.pls] (For use with Real, iTunes, Quicktime, Winamp) Play list looks like this: [playlist] NumberOfEntries=1 File1=http://22.214.171.124:80/ or MP3 pointed to with an Advanced Stream Redirector file [whyy.asx] (For use with Windows Media Player) The ASX file simply contains a URL e.g. http://126.96.36.199:80 or a RealMedia stream [live40.ram] A realMedia stream file contains a URL like: rtsp://streamer.whyy.org/encoder/live.rm CU-SeeMe - Video Conferencing (Will work on over a 28.8 kbps modem.) VDOLive - Live motion video which can run in real time at up to 15 frames per second with a 28.8 kbps modem. (video/vdo .vdo) VXtreme - Streaming Audio/Video format used by CNN. Resolution ranges from 10-20 fps w/ a 160x120 window at 28.8Kbs to 20 fps w/ a 640x480 window at 1 Mbs PointCast - Push Technology that delivers news automatically. Internet Relay Chat (IRC) - A multi-user version of UNIX talk. It works like a text version of CB radio. Real Audio - Real Time AM radio quality Audio over a 14.4Kbs modem. (FM/broadcast quality over a 28.8kbs modem and near-CD quality over ISDN) Progressive Networks, who developed RealAudio, also has RealVideo. (audio/x-pn-realaudio .ra or .ram) (A .ram file is a link to a .ra file which contains something like: rtsp://media.real.com/showcase/service/samples/b56realaudio8.rm (audio/x-pn-realaudio-plugin .rpm) See RealAudio and RealVideo Test Clips In Aug. '97 MCI and Progressive Networks introduced RealNetwork a service that will for the first time deliver audio and video to broadcast-size audiences over the Internet using RealAudio technology. Windows Media Player See Windows Media Player multimedia file formats at Microsoft Internet Phone e.g. The VocalTec Telephone Gateway reduces long-distance telephone charges by routing calls and FAXs from the PSTN over the Internet. Virtual Reality Modeling Language (VRML) - A standard language for describing interactive 3-D objects and worlds delivered across the Internet. In Aug. '97 Microsoft and Netscape agreed on the VRML standard and said they would incorporate it into future versions of their browsers.
