Introduction:

The display of cytometric audio and video information on the Internet is useful for the display of critical steps in sample preparation, for the explanation of complex images and for the demonstration of particular instrument functions.

Network browsers like Netscape 2.x or 3.x versions use plugins for the execution of specific functions like audio or video replay,on-line radio/TV or on-line telephone/video communication.

Plugins are software drivers converting various audio or image formats into browser compatible formats. Plugins are different for different network browsers, Windows versions and computer platforms like PC or MacIntosh.

Audio:

Replay:

PC under Windows3.x (e.g. Netscape2.x, 16bit) or Windows95 (e.g.Netscape Gold2.02 or 3.0, 32bit)

Start audio message by double left or single right mouse click on sound icon,
or download plugin by a left mouse click on the green double cross icon !

Recording:

A PC sound card, a microphone and driver software for the proper operation of the card are required for audio recording under Windows3.x (Accessories/Sound Recorder) or Windows95 (Accessories/Multimedia/Sound Recorder).

Notebook computers are sometimes equipped with a multimedia card and an internal microphone. Audio documents in PC's are frequently recorded in: .WAV format.

Plugins:

Windows3.1:
Audio plugins are required for the Netscape2.0 16 bit browser. MIDI audio format plugins are available, information on audio .WAV file plugin will be soon provided.

Windows95:
Audio plugins are standard features in the Netscape Gold 3.0 32 bit browser.

Audio Call in .htm Documents:

Sound documents are embedded in .htm text files as follows:

|embed src="explan1.wav" noerr="true">
|/embed>

| = < in real .htm files

Video:

Replay:

PC under Windows3.x (e.g. Netscape2.x, 16bit) or Windows95 (e.g.Netscape Gold 3.0 or 2.02, 32 bit)

Video: Closed Chamber Piezo-Cell Sorter

Recording:

A PC video card including the software drivers for the card are required. Input from a video or CCD camera as well as from a video recorder is accepted via a BNC or cinch input plug. The video sound tracks may be also be imported via the mono or stereo audio input plugs of the video card.

Captured video sequences are stored e.g. as .AVI files (audio+video). The audio tracks in .AVI files may be either original or they can be patched/superimposed e.g. with .WAV audio files.

AVI files on the Internet contain usually compressed video information. Intel Codec compressed video .AVI files are readily accepted by Netscape plugins while others e.g. Aura compressed .AVI files required special plugins.

MPEG (for Windows95/NT) compressed .MPG files represent another useful video standard.

On-line video is available from VDO-net (Windows95/NT).

Plugins:

Windows3.1:
Video and audio plugins (see above under Audio) are required for the Netscape2.0 16 bit browser

Windows95:
Video (.AVI, Apple Quicktime) and audio plugins are standard features in the Netscape Gold 3.0 32 bit browser.
