Definition of Multimedia
From etymology
“Multi” = “numerous”
“media” = “medium” = “intermediary”
In information field
Multimedia means “multiple means” by which
information is
stored, transmitted, presented and perceived.

CD-Roms / DVDs / WWW
In the past, the word "multimedia" made many users think of
CD-ROMs and later DVDs, not Web sites. But now true
multimedia has come to the Web with the increased online use
of the rich media and interactivity once reserved for CDs.
The Web is just one way to present multimedia along with
CDs, DVDs, and other platforms.
Programs such as Director and Flash have tremendously
enhanced the ability to use the WWW for multimedia
presentations

Digital multimedia
Digital multimedia is the field concerned with the computercontrolled integration of text, graphics, still and moving images,
animation, sounds, and any other medium where every type of
information can be represented, stored, transmitted, and
processed digitally.
4
Challenges of multimedia system design
Host computing power requirement
Data storage and management requirements.
Cross platforms - different hardware and operating systems.
Human interface - Interactivity - the user can control the
presentation of information being presented.
5
Hypermedia
Application of hypertext concept to multimedia documents
Linking or embedding of multimedia objects
System components (e.g. Word-Wide Web)
makeup language
e.g. HyperText Markup Language (HTML)
directory service
e.g. Uniform Resource Locator (URL)
communication protocols
HyperText Transfer Protocol (HTTP),
File Transfer Protocol (FTP)
6
OS & Hardware support for multimedia
The viewer's equipment has to be powerful enough to support
the multimedia presentation.
Real-time services required; e.g., to satisfy the continuous
playback requirements of media data such as digitized audio
and video.
Web surfers who still use a modem, the slow download speed
can make the online multimedia experience sometimes
frustrating.
