What
can we say about the evolution of media that has taken place for thousands of years? Since the dawn of time, people have had the need to communicate with one another This created what we called as communication media
4
Multimedia The notion of Multimedia Consists of two words: Multi (Latin)= many; much; Medium (Latin) = An intervening substance through which something is transmitted or carried on.
5
What is Multimedia?
Multimedia can be any combination of text, graphics, sound, animation and video, to effectively communicate ideas to users delivered by computer or any other electronic devices.
6
What is Multimedia? (Other
definition)
Multimedia
is any 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. Tay Vaughan Multimedia : Making it work 7 th Ed.

Why
Multimedia?
Ease of use Intuitive Interface Immersive experience Self-paced interaction and better retention Better understanding Cost effectiveness More fun = greater efficiency
10
Multimedia has a number of distinct and unique features, including: Based on Edgar Dale (Cone Of Learning), on average, people remember: 10% of what they read, 20% of what they hear, 30% of what they see, 50% of what they hear and see, multimedia approach multimedia rich elements, multi-sensory delivery system can facilitate greater retention of new knowledge
11
12
Types of Multimedia
Linear Multimedia
Users have very little control over the presentation
Nonlinear/Interactive Multimedia
Users dictate the flow of delivery. User control the flow of the show.
13
Types of Multimedia: (1)Linear Multimedia The users sit back and watches the presentation The presentation normally plays from the start to end or even loops continually to present the information. A movie is a common type of linear multimedia
14
Types of Multimedia: (2)Interactive Multimedia
The users control the delivery of elements to control the what and when. Users have the ability to move around or follow different path through the information presentation. Advantage: complex domain of information can be presented. Disadvantage: users might lost in the massive information highway. Useful for: information archive (encyclopedia), education, training and entertainment.
15
What
is a Multimedia Project?
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. 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.
16
Delivering and Using Multimedia The primary media for delivering multimedia projects are:
Compact disc read-only (CD-ROM). Digital Versatile Disc (DVD) / Blu-ray Disc
Multimedia Projects can also be delivered online (webs) and through PDAs/Hand-held Devices
17
Delivering and Using Multimedia : (1) 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.
18
Delivering and Using Multimedia : (2) DVD / Blu-ray
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. BD Blu-ray disc (Blu-ray Disc Association BDA)
next-generation format for high-definition video and high-density data. A single-layer disc can fit 23.3, 25, or 27 GB (enough for approximately four hours of high-definition video with audio) supports 25GB for one layer, 50GB for two and 100GB for four
19
Delivering and Using Multimedia (3) Online Multimedia can be delivered online Copper wire, glass fiber, and radio/cellular technologies also serve a means for delivering multimedia files across a network Online uses include:
Books and magazines, Education
Movies, Entertainment
News and weather
Maps
20
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.
21
Application 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.
22
Multimedia Applications Examples of Multimedia Applications:
Digital video editing and production systems Electronic Newspapers/Magazines Games Groupware Home shopping Interactive TV Multimedia courseware Video conferencing Video-on-Demand (VoD) Virtual reality
23
Multimedia System Characteristics
Multimedia systems must be computer controlled. All multimedia components are integrated. The interface to the final user may permit interactivity. Information must be represented digitally.
24
Overlapping Technologies
Different branches of multimedia grow together because of new, upcoming multimedia technology and applications. Two challenges lie ahead:
Timing requirements (synchronization etc.) Integration requirements (of different media types)
25
Summary
Multimedia is the combination of text, graphics, sound, animation and video, to effectively communicate ideas to users delivered by computer. 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. Multimedia is widely used in business, schools, public places, and at home.

Chapter 2- Introduction to making Multimedia
The stages of a Project 1. Planning and Costing 2. Designing and Producing 3. Testing 4. Delivering
28
Planning and Costing
A multimedia project always begin with an idea or a need that refine by outlining its messages and objectives. Identify how you will make each message and objective work within your authoring system
29
Desingning and Producing
Perform each of the planned tasks tp create a finished product
30
Testing
Always test your multimedia program to make sure that they meet the objectives of your project, work properly on the intended platform and meet the needs of your client or end user
31
Delevering
Package and deliver the project to the en user
