CGMB113: MULTIMEDIA TECHNOLOGY

1. CGMB113: MULTIMEDIA TECHNOLOGY CHAPTER ONE: INTRODUCTION TO MULTIMEDIA EZE MANZURA MOHD MAHIDIN Adapted from Notes Prepared by: T.J. ISKANDAR ABD. AZIZ

2. Objectives At the end of this chapter, students should be able to: • define basic terms and concepts related to multimedia technologies • understand the history and evolution of media and multimedia technologies • distinguish between the types of linear and non-linear multimedia systems • state the four characteristics of multimedia system

3. 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.

4. What is Multimedia? Multimedia is a combination of digitally manipulated text, graphics, sound, animation and video, to effectively communicate ideas to users delivered by computer or any other electronic devices.

5. 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 7th Ed.

6. What is Multimedia? (Other definition) ‘“Multimedia is the presentation of a (usually interactive) computer application, incorporating media elements such as text, graphics, video, animation and sound on computer.” Stephen McGloughlin Multimedia: Concepts & Practice

7. History Of Multimedia

9. HISTORY :DIGITAL MULTIMEDIA

11. History Of Multimedia • 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 http://www.december.com/present/mediaev.html

12. Digital environment USER Multimedia Building Block Elements of Multimedia

13. Other Terms Related To Multimedia • Hypertext • Nonlinear application whereby user is can navigate freely, by following links that point to other parts of the document, or to other documents. • Hypermedia • When the application is provided with a structure of linked elements through which the user can navigate. • Examples: text, picture, icon that can be clicked and link to other pages.

14. Other Terms Related To Multimedia • Multimedia • means that computer information can be represented through audio, graphics, images, video, and animation in addition to traditional media • Interactive multimedia. • User is allowed to control what and when the elements are delivered.

15. Why Multimedia? Ease of use - Intuitive Interface Immersive experience Self-paced interaction and better retention Better understanding Cost effectiveness More fun = greater efficiency Active participation Accelerated learning – speed up learning process

16. Multimedia rich elements in a multi-sensory delivery environment can facilitate greater retention of new knowledge • 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

18. 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.

19. What is a Multimedia Project/Title? • The software vehicle, the messages, and the content together constitute a multimedia project. • A multimedia project sold to end-users is called a multimedia title. • A multimedia project/title can also be launched on the Web. • Authoring tools are used to merge multimedia elements into a project.

20. 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 • online (webs) • through applications in PDAs/Hand-held Devices /tablet /smartphone /ipad

21. Delivering and Using Multimedia : 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.

22. Delivering and Using Multimedia : 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 burners are used for reading discs and converting the disc to audio, video, and data formats.

23. Delivering and Using Multimedia : Blu-Ray • 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

24. Delivering and Using Multimedia : On line • 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

25. 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.

26. 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.

27. Multimedia Applications Examples of Multimedia Applications: • Digital video editing and production systems • Electronic Newspapers/Magazines • Games • Home shopping • Interactive TV • Multimedia courseware • Video conferencing • Video-on-Demand (VoD) • Virtual reality

28. 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.

29. 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.
