Integrating and Delivering Multimedia

• A use of computers to present text, graphics,
  audio, video, and other media elements integrated
  into one application
• TV has multimedia but not interaction
• e-Games, e-education, e-news,e-commerce,
  e-entertainment, e-books, e-reference, e-betting

Multimedia Comes of Age

• HARDWARE
• Scanners, digital cameras,video capture cards,
  The mouse
• SOFTWARE
• Hypertext
• HyperCard in the late 1980s
• Multimedia encyclopedias in early 1990s were the
  first full-fledged hypermedia products

10
Multimedia Composition Software

• Multimedia composition software is designed to
  incorporate elements of different media into a
  common digital environment
• import sound files, image files, video files
• create graphical objects and recording sound
• Multimedia presentation software is a popular
  sub-category of this type of software
• PowerPoint
• Astound
• Corel Presentations,
• HyperStudio, etc.

Multimedia Authoring Software

• Multimedia Authoring software is designed to
  incorporate elements of different media into a
  common interactive digital environment
• Range of interactive features is much greater
  than with multimedia composition software
• Products can be tailored with programming
  (scripts)
• Applications
• Computer-based training(CBT)
• Informational kiosks
• Computer games
• Edutainment

17
Multimedia Authoring SoftwareBuilt-in
Programming Languages

• authoring tools have their own proprietary
  programming language to write scripts
• Scripts are typically event-driven, (activated by
  the occurrence of some event)
• Mouse movement,
• Clicking the mouse
• Pressing the Enter key,
• timed sequences of events
• completion of certain events, etc.

18
Popular Authoring Software

• HyperStudio, HyperCard
• low-end authoring software with similar
  interfaces
• allows only elementary animation
• products are called stacks (of cards)
• Director
• an animation software for the desktop
• operates with a stage metaphor, products are
  called movies
• Authorware
• A software application with user interaction
• programming flowchart metaphor

Interactive Multimedia on the WebFirst
Generation Tools

• Animation
• animated GIFs
• external video files
• Java applets
• Interactivity
• HTML forms and CGI(Common Gateway Interface)
  scripts
• server-side image maps
• client-side image maps
• Programming with Java
• Java is designed especially for use on networks
• code runs on any machine with the Java runtime
  environment software installed

23
Interactive Multimedia on the WebEmerging
Technologies

• Dynamic HTML (DHTML) User interaction
• dynamic style sheets
• dynamic data content
• dynamic object positioning
• Extensible Markup Langauge (XML)
• complementary to HTML
• adds tremendous flexibility to Web pages
• applications can describe to each other a
  documents data and its relationships

Multimedia Development Life Cycle

• Analysis -- decide on content, audience, and
  delivery
• Design -- organize the overall multimedia
  document
• Scripting -- specify details of all the
  components that make up the product
• Production -- author the document based on the
  script

Summary

• Hardware and software systems for delivering
  interesting multimedia content have gradually
  evolved over the past decade
• Multimedia composition software is widely used
  for producing multimedia presentations, but
  usually offers little interactivity
• Multimedia authoring software offers extensive
  interactivity as well as full multimedia
  integration
• The Web provides limited multimedia authoring and
  interactivity but its capabilities in this regard
  will no doubt improve in the future
• The development of professional multimedia
  products proceeds in stages and is ordinarily
  completed by teams of specialists
