multimediawhen a user is given the option

of controlling the elements.Interactive multimedia is called

hypermediawhen a user is provided a

structure of linked elements for navigation.Multimedia developersdevelop multimedia

[Introduction to Multimedia]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.


7/24Chapter 1: What is Multimedia?

[Introduction to Multimedia]Multimedia projects can be linearor

nonlinear.

Projects that are not interactive are calledlinear.

Projects where users are given

navigational control are called non-linearand user-interactive.


8/24


[Introduction to Multimedia]Authoring toolsare used to merge

multimedia elements into a project.

These software tools are designed tomanage individual multimedia elements

and provide user interaction.


9/24


[Introduction to Multimedia]The primary media for delivering

multimedia projects are:

Compact disc read-only (CD-ROM).Digital Versatile Disc (DVD).


10/24


[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 burnersare used for reading discs andconverting the discs to audio, video, and

data formats.


11/24


[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 burnersare used for reading discs

and converting the disc to audio, video,

and data formats.


12/24


[Introduction to Multimedia]Copper wire, glass fiber, and radio/cellular

technologies also serve as means for

delivering multimedia files across anetwork.


13/24


[Multimedia Application]

A computer based interactive communicationprocess that incorporates media elements suchas text, graphics, sound, animation and videoon a computer.

Interactivityis the key component to deliver aninteractive multimedia application

Interactivityability of user to interact with theprogram

The ability of the user to interact with the programis perhaps the single most critical features ofmultimedia.


14/24


[Multimedia Application]Multimedia application can be either linearornon-linear

Linear

Not interactive

Starting at a beginning and running through the end

Eg. Montage on TV

Non-linearInteractive

Ability of end user to interact and control theapplication

Eg. Games software


15/24


[Multimedia Application]

All these media are structured in such a

way that the audience has control over

their presentation..is when end users are allowed to control

what & when the elements are delivered


16/24


[Applications Of Multimedia]

Multimedia is a very effective presentation

and sales tool.

Multimedia in businessMultimedia in schools

Multimedia at home

Multimedia in public places


17/24


[Applications 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 bedeveloped to enrich the learning process.


18/24


[Applications of Multimedia]Home - Most multimedia projects reach

the homes via television sets or monitors

with built-in user inputs.Public places- Multimedia will become

available at stand-alone terminals or

kiosks to provide information and help.


19/24


[Interactive Multimedia]

Interactive multimediais when user areallowed to control what & when the elements aredelivered.

Hypermediais interactive multimedia when astructure of linked elements through which theuser can navigate.

Virtual realityis interactive multimedia to thefullest extension.

Hypertextis when words are keyed or indexedto other words. The text part of this termrepresent the projects content and meaning,rather then the graphical presentation.


20/24


[Multimedia Terminologies]

Multimedia developers

Multimedia title

Storyboarding

Authoring tools

Graphical user interface (GUI)


21/24


[Multimedia Terminologies]Multimedia developers: the people who weavemultimedia elements into meaningful tapestries

Multimedia title: if the project will be shipped or sold toconsumers or end users, typically in a box or on the

Internet, with or without instructionsStoryboarding : determining how a user will interact withand navigate through the content of a project

Authoring tools : these software tools are designed to

managed individual multimedia elements and providemultimedia interaction

Graphical User Interface (GUI): the sum of what getsplayed back and how it is presented to the viewer


22/24


[Virtual Reality (VR)]Virtual reality is an extension of

multimedia.

It uses the basic multimedia elements ofimagery, sound, and animation.

It requires terrific computing horsepower to

be realistic.


23/24


[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 theWorld Wide Web.

VRML documents have the file extension

.wrl.

[Summary]

Multimedia is a combination of text, graphic art,

sound, animation, and video.

Multimedia projects can be linearor nonlinear.Multimedia projects are often stored on CD-ROM
