MULTIMEDIA 1


What is Multimedia?
• An interactive combination of two or more media elements (multimedia building block), such as text, graphics, audio, animation and video integrated using a computer.
Multimedia
• Multimedia is any combination of text, graphics, sound, animation and video that  is delivered by computer
• A multimedia project development requires creative, technical, organizational, and business skills.
 • When you allow the user to control what and when these elements are delivered, it is interactive multimedia
What is multimedia System?
• A system that supports more than a single type of media
Multimedia Building Blocks
Digital environment
USER
Why multimedia?
–Ease of use –Immersive (virtual reality) experience –interaction and better retention –Better understanding –Cost effectiveness –More fun = Greater efficiency
Retention - Capacity or power of retaining  or An ability to recall or recognize what has been learned or experienced.
Integration
• The integration of simulation tools with multimedia elements makes it possible to express in a richer way the knowledge we are trying to provide, and gives the audience a better comprehension of the problem, as explanations by means of video, images, texts, etc.
Integration
• Integrating Multimedia and Hypermedia into Teaching and Learning
 • well-integrated multi-media can only improve the usability and stickiness of your site
stickiness- the property of sticking to a surface
Interactive
• Key feature of multimedia
• User determines what content is delivered, when it is delivered and how
Hypermedia HTML
• HyperMedia: not constrained to be text-based, can include other media, e.g., graphics, images, and especially the continuous media - sound and video. – The World Wide Web (WWW) – is an example of a hypermedia application.
 • Multimedia means that computer information can be represented through audio, graphics, images, video, and animation in addition to traditional media.
 • A hypertext(links) system: meant to be read nonlinearly, by following links that point to other parts of the document, or to other documents.
Hypertext is nonlinear
HTML(Hyper Text Markup Language)
• HTML: a language for publishing Hypermedia on the World Wide Web 
1. HTML uses ASCII, it is portable to all different (possibly binary incompatible) computer hardware. 
2. The next generation of HTML is XHTML - a reformulation of HTML using XML.
 • HTML uses tags to describe document elements
HTML(Hyper Text Markup Language)
• A very simple HTML page is as follows:
 <HTML>
 <HEAD> 
<TITLE> A sample web page. </TITLE>
 <META NAME = "Author" CONTENT = "Cranky Professor"> 
</HEAD> 
<BODY>
 <P> We can put any text we like here, since this is a paragraph element. </P>
 </BODY> 
</HTML> 
• Naturally, HTML has more complex structures and can be mixed in with other standards.
Multimedia Authoring
• creation of multimedia productions, sometimes called “movies" or “presentations". –we are interested in interactive applications. –we also look at still-image editors such as Adobe Photoshop, and simple video editors such as Adobe Premiere.
Multimedia Authoring
• Adobe/Macromedia Flash: allows users to create interactive movies by using the score metaphor, i.e., a timeline arranged in parallel event sequences.
• Adobe/Macromedia Director: uses a movie metaphor to create interactive presentations - very powerful and includes a built-in scripting language
• Lingo, that allows creation of complex interactive movies.
• Adobe/Macromedia Authorware: a mature, well- supported authoring product  creating interactive programs that can integrate a range of multimedia content, particularly e-learning applications.
Delivering  Multimedia
• Compact disc Inexpensive, easy mass produce and distribute 
• Online Web pages, product advertisement, demos

WHO USES ADOBE DIRECTOR?
Multimedia authors
 • Easily create and publish interactive CD-ROM discs, and rich Internet applications (RIAs). Realize the greatest return on your creativity with cross-platform authoring and playback. Game developers
• Develop engaging experiences with state-of-the- art audio capabilities, native 2D/3D rendering, and enhanced built-in technology. eLearning application authors
 • Engage learners by adding new dimensions to your training and simulation applications.
