Notes CSC413 CHAPTER 1 WHAT IS 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 requires creative, technical, organizational, and business skills.
¢  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.
¢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 Web.
¢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.
¢Authoring tools are used to merge multimedia elements into a project.
¢These software tools are designed to manage individual multimedia elements and provide user interaction.
The primary media for delivering multimedia projects are:
 
¢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.
¢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.
¢Copper wire, glass fiber, and radio/cellular technologies also serve a means for delivering multimedia files across a network.
 
APPLICATION OF MULTIMEDIA
¢Business - Business applications for multimedia include presentations training, marketing, advertising, product demos, databases, catalogues, instant messaging, and networked communication.
¢Schools - Educational software can be developed to enrich the learning process.
¢Home (gardening, cooking, home designing) – Most multimedia projects reach the homes via television sets or monitors with built-in user inputs.
¢Public places (hotels, train stations, shopping mall, museums) – Multimedia will become available at stand-alone terminals or kiosks to provide information and help.
 
¢Virtual reality is an extension of multimedia.
goggles, helmets, gloves – to place user “inside” a lifelike experience.
 ¢It uses the basic multimedia elements of imagery, sound, and animation. 
¢It requires terrific computing horsepower to be realistic.
 
¢In VR, cyberspace is made up of thousands of geometric objects plotted in three-dimensional space.
¢The more objects, the more points describe the object, the higher resolution – more realistic
¢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.
