History of Multimedia

• Newspaper: first mass communication medium, uses text, graphics, and images
• Motion Pictures: conceived in 1830s to observe rapid motion
• Wireless Radio Transmission: Guglielmo Marconi, Italy, 1895
• Television: established video as a commonly available medium

Hypermedia and Multimedia

• Hypertext System: read nonlinearly by following links
• Hypermedia: includes multimedia, graphics, images, sound, and video
• World Wide Web (WWW): best example of a Hypermedia application
• Multimedia: represents computer information through audio, graphics, images, video, and animation

Multimedia Software Tools

• Categories: text, audio, images, drawings, animation, and video
• Examples: video teleconferencing, distributed lectures, tele-medicine, and augmented reality

Interactive and Static Media

• Interactive Media: user has control over elements
• Static Media: no temporal component, no synchronization among data

Linear vs. Non-Linear Multimedia

• Linear: not interactive, user has no control
• Non-Linear: interactive, user has control and navigational control
• Examples: movies, games, and courseware

Digital vs. Analog

• Digital Data: represented as binary data
• Analog Data: represented based on medium property

Multimedia Applications

• Examples: digital video editing, electronic newspapers, World Wide Web, on-line reference works, home shopping, interactive TV, and multimedia courseware

Importance of Multimedia

• Fields where multimedia is useful: business, education, entertainment, home, and public places
• Examples: sales/marketing presentation, staff training, courseware, e-learning, games, and information kiosk
