  3. 1. Course Detail • Course Name – Multimedia technologies • Credit Hour – 03 How this course will proceed – Stream 1: Lectures will be delivered. Assignments, Quizzes, Exams – Book: Digital Multimedia By: Nigel Chapman and Jenny Chapman – Stream 2: Practical Assignments will be given Tools will be introduced and Tutorials may be scheduled (on demand) – Tools: Macromedia Products, Adobe Products, Corel Products, Discreet Products

  4. 2. What Is Multimedia? • Multimedia is a computer-based interactive communications process that incorporates text, graphics, sound, animation, and video • The shared digital representation that combines different media together can be loosely called Multimedia

  5. 3. Applications of Multimedia • Interactivity – That goes beyond the simple control offered by VCR – Where you can change the story by altering the events that occur – Where you can choose to have transcription if there is hearing impairment – Where you can choose to hear what is written if you have impaired vision • Forensic Multimedia – Where jury members can examine the events from different angle • Entertainment – Games | Starship Titanic, Doom and its bloody off springs, Prince of Persia – Movies | … • Education – Cinemania, Encyclopedia, Britannica – CBTs : Computer Based Trainings – Simulations

  6. 4. Visualization How to represent a particular data, information etc.. • Pie Charts / Bar Charts generated from a spreadsheet • Three Dimensional Data Representations • Time Varying Presentations for complex dynamic systems – Atmospheric dynamic to represent a tropical storm • Linear or Non Linear Behaviors – TV Programs – Block Buster Movies – Web Sites • Creativity – Target Audience – Keen Observations – Lots of exposure to similar area – In‐depth Analysis – Re Creation in a better way – Open to Criticism

  7. 5. Delivery of Multimedia • Online Delivery – Uses a network to send information from computer, often server machine providing centralized storage of bulky data, to another, usually a personal computer on somebody’s desk. – The network can be LAN, Internet (World Wide Web) • Offline Delivery – Uses some removable storage medium – CD ROMs / DVDs

  8. 6. Multimedia Production Making of Multimedia requires software not only for preparation of individual media elements, but for their integration into finished production. • Authoring Systems – Programs that allow a designer to assemble different media elements in space and time, and add interactive behavior to them. – These systems interpret user actions and commands in a non‐trivial ways in order to translate the mode of working that is natural to designer. • Story Boards – Mean of making and communicating multimedia designs. – Used in large animation studios, and by music videos and advertisement producers, to plan the construction of a piece of work, and to communicate its structure among the team producing it. – A sequence of still picture showing the composition of shots at key points in production. – So it plans the work, which can be used to organize its subsequent development. – Linear in behavior like a comic strip.

  9. • Initial Story Board

  10. • After Multimedia Production

  11. 7. Terminology • What do call a mixture of media under software control? • Multimedia Production – Where the display and presentation of media elements is a sole purpose – Web Page or an encyclopedia on CD‐ROM • Multimedia Application – Where the display of the multimedia is more intimately bound up with computation

  12. 8. User Interface • Means by which choices can be presented to users can vary enormously. • Menus, Dialog Boxes, Outlined Buttons and so on…

  13. 9. Evolution of Multimedia • 1945 ‐ Vannevar Bush (1890‐1974) wrote about Memex • 1960s ‐ Ted Nelson started Xanadu project • 1967 ‐ Nicholas Negroponte formed the Architecture Machine Group at MIT • 1968 ‐ Douglas Engelbart demonstrated NLS system at SRI • 1969 ‐ Nelson & Van Dam hypertext editor at Brown • 1976 ‐ Architecture Machine Group proposal to DARPA: Multiple Media • 1985 ‐ Negroponte, Wiesner: opened MIT Media Lab • 1989 ‐ Tim Berners‐Lee proposed the World Wide Web to CERN • 1990 ‐ K. Hooper Woolsey, Apple Multimedia Lab • 1992 ‐ The first M‐Bone audio multicast on the Net • 1993 ‐ U. Illinois National Center for Supercomputing Applications: NCSA Mosaic • 1994 ‐ Jim Clark and Marc Andreesen: Netscape • 1995 ‐ JAVA for platform‐independent application development.

  14. 10. Multimedia Applications • Hypermedia Courseware • Video Conferencing • Video‐on‐demand • Interactive TV • Groupware • Home Shopping • Games • Virtual Reality • Digital video editing and production systems
