Definition - Multimedia

• Multimedia is any combination of text, graphic,

sound, animation and video that is delivered by

computer.

• Integration of multiple forms of media, including

text, graphics, audio, video, etc.

• Multimedia is used to convey information in an

interesting way.


4


Definition - Multimedia Developers

The people who create multimedia projects.


5


Definition - Multimedia Projects

The multimedia materials, which are part of a particular

topic or subject, presented on a computer or television

screen.


6


Definition - Multimedia Title

A multimedia project shipped

or sold to consumers.


7


Definition - Interactive Multimedia

When the multimedia user is allowed to control what

elements are to be delivered and when they are to be

delivered.

Multimedia Usages

Multimedia can be used in:

• Education

• Marketing

• Training

• Scientific Research

• Engineering


9


Multimedia Usages

Computer-Based Training Teaching Aid

13


Multimedia Requirements

• Creative skills

• Technology tools

• Organization and business talent


14


Advantages of Multimedia

1. Enhancement of Text Only Messages

Multimedia enhances text only presentations by

adding interesting sounds and compelling visuals.


15



2. Improves over Traditional Audio-Video Presentations

Audiences are more attentive to multimedia

messages than traditional presentations done with

slides or overhead transparencies.


16



3. Gains and Holds Attention

People are more interested in multimedia messages,

which combine the elements of text, audio, graphics

and video.


17



4. Good for "computer-phobics“

Those who are intimidated by computer keyboards

and complex instructions are more comfortable with

pressing buttons with a mouse or on a screen.


18



5. Multimedia is Entertaining as Well as Educational


19


Disadvantages of Multimedia

1. Expensive

2. Not always easy to configure

3. Requires special hardware

4. Not always compatible


20


Multimedia Categories

• Linear

• Non-Linear


21



• Linear active content

progresses without any

navigation control for the

viewer such as a cinema

presentation.


22




23



• Non-linear content offers user

interactivity to control progress

as used with a computer

game or used in self-paced

computer based training.


24




25



• Multimedia presentations can be live or recorded.

• A recorded presentation may allow interactivity via

a navigation system.

• A live multimedia presentation may allow

interactivity via interaction with the presenter or

performer.


26


Multimedia Systems

• A Multimedia System is a system capable of

processing multimedia data and applications.


27


Multimedia Systems

• A Multimedia System is characterized by

– The processing

– Storage

– Generation

– Manipulation

– Rendition of Multimedia information.


28


Characteristics of a Multimedia System

A Multimedia system has four basic characteristics:

• Multimedia systems must be computer controlled.

• Multimedia systems are integrated.

• The information they handle must be represented

digitally.

• The interface to the final presentation of media is

usually interactive.


29



1. Computer Controlled

• Producing the content of the information – e.g. byusing the authoring tools, image editor, sound andvideo editor

• Storing the information – providing large andshared capacity for multimedia information.

• Transmitting the information – through the network.

• Presenting the information to the end user – makedirect use of computer peripheral such as displaydevice (monitor) or sound generator (speaker).


30



2. Integrated

• All multimedia components (audio, video, text,graphics) used in the system must be somehowintegrated.

• Every device, such as microphone and camera isconnected to and controlled by a single computer.

• A single type of digital storage is used for all mediatype.

• Video sequences are shown on computer screeninstead of TV monitor.


31



3. Interactivity

• Level 1: Interactivity strictly on information delivery.Users select the time at which the presentationstarts, the order, the speed and the form of thepresentation itself.

• Level 2: Users can modify or enrich the content ofthe information, and this modification is recorded.

• Level 3: Actual processing of users input and thecomputer generate genuine result based on theusers input.


32



4. Digitally Represented

• Digitization: process involved in transforming an

analog signal to digital signal.


33


Components of a Multimedia System

• Capture devices / Input Devices

– Keyboard, scanner, video camera

• Storage Devices

– Hard disk, optical disc

• Communication Network

– Modem, network card, cables

• Computer System

– CPU, RAM, Display card

• Display Devices

– Monitor, Projector, Printer


34


What is Multimedia Application?

• Any computer application that contain or use

Multimedia elements.

• A multimedia application is more like a movie or a

book.

• Content must be created and produced.

• Usually interactive.


35


Examples of Multimedia Application

• World Wide Web

• Hypermedia courseware

• Computer-based Training (CBT)

• Interactive TV

• Computer Games

• Virtual reality

• Multimedia Database systems


36


Delivering Multimedia

• Multimedia can be delivered using

– Optical disk (CD-based)

– Over a distributed network (Web-based)


37



Optical Disks

• The most cost-effectivemethod of delivery formultimedia materials.

• These devices are used tostore large amounts of somecombination of text,graphics, sound, and movingvideo.


38



Optical Disks

Media Storage

Compact Disc (CD) 650MB

Digital Versatile Disc (DVD) 4.7GB

Bluray Disc (BD) 27GB


39



Distributed Network

• Suitable for web-based

content eg. website

• Files need to be compress

before transfer


40



Web-based CD-based

Limited in picture size and

low video resolution

Can store high end

Multimedia elements

Can be changes,

damaged or deleted by

irresponsible individuals

Can be permanently

stored and not

changeable

Information can be

updated easily and

cheaper

Information can be quickly

outdated
