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