¢ 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.
