  1. Lesson 1-What is Multimedia?

  2. Overview • Introduction to multimedia. • Applications of multimedia. • Virtual reality (VR).

  3. Introduction to Multimedia • Multimedia is a combination of text, art, sound, animation, and video. • It is delivered to the user by electronic or digitally manipulated means. • A multimedia project development or a web site requires creative, technical, organizational, and business skills. • Keys to successful development of a multimedia project are • Management of digital tools and skillsets, • Teamwork, • General project management, • Documenting and archiving the process, • Delivering the completed product on time and within budget.

  4. Introduction to Multimedia-Definitions • Multimedia is woven combination of digital manipulated text, photographs, graphic art, sound, animation, and video elements • Multimedia becomes interactive multimedia when a user is given the option of controlling the elements. • Interactive multimedia is called hypermedia when a user is provided a structure of linked elements for navigation. • Multimedia developers develop multimedia projects.

  5. Introduction to Multimedia-Definitions • The software vehicle, the messages, and the content together constitute a multimedia project. • A multimedia project shipped to end-users with or without instructions is called a multimedia title. • A project can also be launched on the World Wide Web (WWW) where you can weave the elements of multimedia into document with HTML (Hypertext Markup Language) or DHTML (Dynamic HTML).

  6. Introduction to Multimedia-Definitions • Multimedia projects can be linear or nonlinear. • Projects that are not interactive are called linear. • Projects where users are given navigational control are called non-linear and user-interactive.

  7. Introduction to Multimedia-Definitions • Authoring tools are used to merge multimedia elements into a project. • Macromedia Director, Authorware, Ulead Media Studio • These software tools are designed to manage individual multimedia elements and provide user interaction. • The sum of what gets played back and how it is presented to the viewer on a monitor is the graphic user interface (GUI). • The hardware and software that govern the limits of what can happen are the multimedia platform or environment.

  8. Introduction to Multimedia -CD-ROM and the Multimedia Highway The primary media for delivering multimedia projects are: • Compact disc read-only (CD-ROM).: Red Laser • 640MB • Digital Versatile Disc (DVD): Blue Laser • 單面單層: 4.7GB • 單面雙層: 8.5GB • 雙面單層: 9.4GB • 雙面雙層: 17GB

  9. Compact Disc Read-Only(CD-ROM) • CD-ROM is the most cost-effective distribution medium for multimedia projects. • It can contain up to 80 minutes of full-screen video or sound. • CD burners are used for reading discs and converting the discs to audio, video, and data formats.

  10. Digital Versatile Disc (DVD) • Multilayered DVD technology increases the capacity of current optical technology to 18 GB. • DVD authoring and integration software is used to create interactive front-end menus for films and games. • DVD burners are used for reading discs and converting the disc to audio, video, and data formats.

  11. Introduction to Multimedia-The Multimedia Highway • Telecommunication networks are global and information elements will link up online as distributed resources on a data highway. • Copper wire, glass fiber, and radio/cellular technologies also serve a means for delivering multimedia files across a network. • Examples: Full-text content from books and magazines; Street maps of any city; feature movies are displayed at home; real-time news reported from anywhere on earth; lectures from participating universities.

  12. Applications of Multimedia • Business - Business applications for multimedia include presentations training, marketing, advertising, product demos, databases, catalogues, instant messaging, and networked communication.

  13. Applications of Multimedia • Schools - Educational software can be developed to enrich the learning process. Figure 1-2. Just Grandma and Me. Figure 1-2. A Project from Yale University

  14. Applications of Multimedia • Home - Most multimedia projects reach the homes via television sets or monitors with built-in user inputs.

  15. Applications of Multimedia • Public places - Multimedia will become available at stand-alone terminals or kiosks to provide information and help.

  16. Applications of Multimedia • TABLE 1-1 Scribin’s Color Organ

  17. Virtual Reality (VR) • Virtual reality is an extension of multimedia. • It uses the basic multimedia elements of imagery, sound, and animation. • It requires terrific computing horsepower to be realistic.

  18. Virtual Reality (VR) • In VR, cyberspace is made up of thousands of geometric objects plotted in three-dimensional space. • The standards for transmitting VR in Virtual Reality Modeling Language (VRML) documents have been developed on the World Wide Web. • VRML documents have the file extension .wrl.

  20. Summary • Multimedia is a combination of text, graphic art, sound, animation, and video. • Multimedia projects can be linear or nonlinear. • Multimedia projects are often stored on CD-ROM or DVDs. They can also be hosted on the Web.

  21. Summary • Multimedia is widely used in business, schools, public places, and at home. • Virtual reality is an extension of multimedia.
