Definition of Multimedia

    medium intermediary
  • In information field Multimedia means multiple
    means by which information is stored,
    transmitted, presented and perceived.

3
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 computer-controlled 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.

5
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.

6
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)

7
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.

8
Key Figure in the www
  • Tim Berners-Lee is the Director of the World
    Wide Web Consortium, a Senior Research Scientist
    and the 3COM Founders Professor of Engineering in
    the School of Engineering, with a joint
    appointment in the Department of Electrical
    Engineering and Computer Science MIT's CSAIL
    where he leads the Decentralized Information
    Group (DIG), and Professor of Computer Science at
    Southampton ECS.
