  1. Introduction to Multimedia Professor: Jim Habermas jrh@it.rit.edu

  2. 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.

  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 http://www.7up.com http://www.coke.com/flashIndex1.html

  4. 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 protocolsHyperText 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 SouthamptonECS.”
