demand)

– Tools: Macromedia Products, Adobe Products, Corel Products, Discreet Products

1. Course Detail

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

2. What Is 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

3. Applications of Multimedia

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

4. Visualization

• 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 onsomebody’s desk.– The network can be LAN, Internet (World Wide Web)

• Offline Delivery– Uses some removable storage medium– CD ROMs / DVDs

5. Delivery of Multimedia

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.

6. Multimedia Production

• Initial Story Board

• After Multimedia Production

• 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

7. Terminology

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

• 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.

9. Evolution of Multimedia

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

10. Multimedia Applications
