3. Multimedia, Interactivity, and New Media Defined
New Media and Digital Convergence

4. Multimedia, Interactivity, and New Media Defined - Multimedia
A medium is a way of conveying information. Speech is one medium, text is another.
There are many kinds of unique media. ("Media" is the plural of "medium.")
Multimedia is the use of more than one type of medium at the same time to convey a message or information.
A lecture presented along with slides is an example of a simple multimedia event.

5. Multimedia, Interactivity, and New Media Defined - Interactivity
Like television, a PC can present many media types simultaneously. For example, text, animation, music, and narration can all play at one time.
TV is not interactive; it only delivers content. The PC enables the use of interactive multimedia such as games and reference products.
Interactivity means that the user and program respond to one another. The program provides an ever-changing array of choices, which the user selects to direct the flow of the program.

7. Multimedia, Interactivity, and New Media Defined - New Media and Digital Convergence
"New media" is a term that encompasses all types of interactive multimedia technologies.
New media bring together not only multimedia content, but delivery technologies such as cable, telephone lines, networks, and the Internet.
New media is based on the concept of digital convergence, which means many different technologies can be used together to deliver different types of content in one digital stream.

8. Information in Layers and Dimensions
The Importance of Content
Hypermedia and Navigation

9. Information in Layers and Dimensions - The Importance of Content
The purpose of multimedia is to make information (content) more interesting, compelling, or enjoyable, as well as easy to navigate.
Multimedia technologies give users choices of the type of content that is presented, and the manner in which it is presented.
Regardless of the technologies used in multimedia, the primary focus is on providing high-quality content.

10. Information in Layers and Dimensions - Hypermedia and Navigation
The process of moving through electronic information is called navigation.
Well designed multimedia products provide a variety of methods for the user to navigate and choose content. Multimedia navigation is based on “hypermedia”.
Hypermedia allows different types of content to be linked together. By choosing a hyperlink, WWW users jump to a new web page or multimedia feature.

12. Hardware Considerations for Multimedia
Most new PCs are multimedia-capable, featuring all the hardware required to play back multimedia content.
To play multimedia content, a PC needs (at the very least) a sound card, speakers, and a CD-ROM or DVD-ROM drive. A large hard disk and lots of RAM are also helpful.
New PCs must meet requirements set in the PC 97 or PC 99 standard to be considered multimedia-compliant.

14. Applications for Multimedia
In the School
In the Workplace
In the Home

15. Applications for Multimedia - In the School
Many types of multimedia tools are being used in schools, from CD-based reference products, to games, to online collaboration.
Distance learning technologies allow schools to provide courses online, over the Internet. These online learning environments are called virtual universities.

16. Applications for Multimedia – In the Workplace
Companies are increasingly using multimedia for sales, marketing, and training.
Using computer-based training (CBT) products, companies can quickly and cost-effectively teach employees new skills.
Because multimedia content can be distributed over the Web, many companies have developed online outlets which enable customers to view and purchase products from their PC.

18. Applications for Multimedia - In the Home
In the home, multimedia products are used largely for the following purposes:
Reference materials
Self-help and instruction
Entertainment
