Technical Considerations:Macintosh Platform

We recommend that you view this exhibit with the latest of any of the currently available browsers. In particular, make sure you are using NCSA Mosaic 2.01 (final release), Netscape 1.12 or Spyglass Mosaic 2.0, or later versions of any one of these browsers. Older versions will NOT display all the multimedia information inside this exhibit. Another point to note is many of the pages are Netscape optimized, so that they may appear slightly different from how they were intended with other browsers. If you are currently using an older version of any of these browsers, use the links below to download the most current versions:

• NCSA Mosaic
• Netscape
• Spyglass Mosaic (NOTE - Spyglass Mosaic is a commercial product.)

Movies:

Development of software to facilitate easier viewing of MPEG and QuickTime movies over the web is in constant flux. Currently, technology that allows "realtime" streaming of video directly to web pages, thus eliminating the need for external players, is available in QuickTime format for some of the Expo movies. To view them, you need the Apple/Netscape plug-in for Netscape 3.0 betas listed below. In current development for MPEG streaming is Vosaic, which will allow audio and video streaming for MPEG movies, AS WELL as providing hyperlinking within movies. There are also some proprietary new formats which support some level of streaming, however, are not worth considering in the mainstream.

Fast Player - for viewing QuickTime movies you download
Sparkle - for viewing MPEG movies you download
Apple/Netscape Plug-in - streamed QuickTime for Netscape 3.0
MovieStar Plug-in - allows viewing of streamed Quicktime movies in Netscape 2.0 and older

For use with the Macintosh, there is a tool available which modifies QuickTime movies appropriately for use with the streaming plugins. It is very easy to use, just open and save. Then upload the movies up to your server.

Sounds:

Sound App - plays all sound formats
Note: With new Atlas Navigator products, the LiveAudio Plug-in alleviates the need for any external sound player.
Note: for Mosaic, the default setting plays audio files internally (no interface). If you wish to change this, use SoundApp as above and configure Mosaic through Preferences in the Options menu.

Graphics/Other:

JPEG View - for viewing external GIF and JPEG images

Configuring your browser to make use of SoundApp (for example):

1. Find your configuration window wherever preferences are accessible
2. Find section that deals with helper applications or mime-types
3. Enter 'audio/x-aiff' to make use of AIFF sound files
4. Click on it and press the 'Browse' button
5. Locate your copy of SoundApp and then close the preferences window
Note: if you are using Netscape, the first time you attempt to download an AIFF or unknown file, Netscape will prompt you for which helper you wish to use. Simply locate and select SoundApp.
