MULTIMEDIA MAGIC!
1_____________________________
Until now multimedia applications have been used mainly in the fields of
information, training and entertainment. For example, some museums, banks and
estate agents have information kiosks that use multimedia. Several companies
produce training programs on optical disks, and marketing managers use
presentation packages (like Microsoft PowerPoint or Lotus Freelance Graphics for
Windows) to make business presentations. They have all found that moving
images, sound and music involve viewers emotionally as well as inform them, and
make their message more memorable.
2_____________________________
Sound is an important component of the multimedia approach. The effective
use of sound can be used to grab the attention of the participant, set the mood or
underscore a point. The most popular way of delivering sound is the hardware
sound board. Such boards offer two important capabilities. The first of these is a
built-in stereo synthesizer complete with a built-in audio amplifier. Just connect a
set of speakers and you've got instant sound, music and speech capabilities. The
second capability is the musical instrument digital interface that allows an
electronic musical instrument to communicate with other MIDI- equipped
instruments or PCs.
3______________________________
Between 80 and 90 per cent of all multimedia applications are distributed on
CD-ROM, some just on CD, some on several media (as with Autodesk's
Multimedia Explorer, which comes with both a CD-ROM and diskettes). The
reason for CD-ROM's popularity in multimedia is simple - a single CD can contain
650 MB of data. That's over 500 floppy disks' worth of programs, sound and
graphics. The newest CD-ROM standard, CD-ROM XA (for extended
Architecture) uses data compression to fit even more on these shiny discs. Many
XA drives are also compatible with Kodak's PhotoCD technology, that digitises
photographs and places them on a CD-ROM.
