Multimedia. Hypermedia. Rich media. Hypertext. Multimedia linear and non-linear categories

Multimedia is simply multiple forms of media integrated together. Media can be text, graphics, audio, animation, video, data, etc.

Multimedia is usually recorded and played, displayed or accessed by information content processing devices, such as computerized and electronic devices, but can also be part of a live performance.

Besides multiple types of media being integrated with one another, multimedia can also stand for interactive types of media such as video games CD ROMs that teach a foreign language, or an information Kiosk at a subway terminal. Other terms that are sometimes used for multimedia include hypermedia and rich media.

Multimedia (as an adjective) also describes electronic media devices used to store and experience multimedia content. Multimedia is similar to traditional mixed media in fine art, but with a broader scope. The term " rich media " is synonymous for interactive multimedia.

The term reach media was coined to describe a broad range of digital interactive media. Rich media can be downloadable or may be embedded in a webpage. If downloadable, it can be viewed or used offline with media players such as Real Networks' RealPlayer, Microsoft Media Player, or Apple's QuickTime, among others. The defining characteristic of rich media is that it exhibits dynamic motion. This motion may occur over time or in direct response to user interaction. Elements of rich media are increasingly used in education, in areas ranging from distance learning to web-based teaching and instructional tools.

Not surprisingly, rich media presents numerous accessibility challenges. However, rich media can be made accessible if all the elements are developed with accessibility in mind and the end product is used or viewed on accessible media players. Accessible rich media typically includes captioning, audio description, and navigation using a keyboard.

Hypermedia can be considered one particular multimedia application. The World Wide Web is a classic example of hypermedia, whereas a non-interactive cinema presentation is an example of standard multimedia due to the absence of hyperlinks. Most modern hypermedia is delivered via electronic pages from a variety of systems including Media players, web browsers, and stand-alone applications. Audio hypermedia is emerging with voice command devices and voice browsing.

Multimedia software is usually interactive, so you can choose what you want to watch, listen to or write. Hypertext means that you can click on a word and jump to another screen with more information; hypermedia is similar, butworks with sounds and images (e.g. the Web).

Multimedia may be broadly divided into linear and non-linear categories. Linear active content progresses without any navigational control for the viewer such as a cinema presentation. Non-linear content offers user interactivity to control progress as used with a computer game or used in self-paced computer based training. Hypermedia is an example of non-linear content. 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 an interaction with the presenter or performer.
