    Multimedia is a comprehensive term and means different types of media. It includes a combination of text, audio, still images, animation, video, and interactivity content forms.

Multimedia content can be broadly divided in to two groups: linear and non- linear. Linear active content progresses without any navigational control for the viewer (as in the case of a cinema presentation); non-linear content , on the other hand, supports user’s interaction to control progress(as in the case of computer games).

Multimedia presentations can be live or recorded. In a recorded presentation, the user can interact via a navigation system, but in a live multimedia presentation , interaction is possible only through the presenter or performer.

Edutainment, which combines education with multimedia entertainment, is now emerging as a trend in schools as well as higher education. This has made learning theories much simpler than ever before. Moreover, visually impaired people and other specially abled people can pursue their careers by using training programs specially designed for them.

Engineers and researchers use multimedia for modeling and simulation.

Software requirements for supporting multimedia data multimedia data can include text , pictures , audio , and video.

Text styling this allows users to make the text more presentable. The options available include different fonts, different font sizes , bold , italic , and various effects(e.g., shadow). 

Text searching This enables users to quickly search for a word or phrase in a document containing a large number of pages.

Hyper text This supports non- sequential navigation of information. When a hyper text is embedded in a document, it is displayed either in a different colour or in a different font. When a user clicks on the hyper text , additional information about the topic is displayed.

Animation creation software This  allows users to create animations using simple objects such as lines, circles, and polygons. While creating an animation , a user selects still images and displays them at a fast speed so that it gives an effect of motion. As an example, a doll moving across the screen.

Animation file importing This feature allows users to import already existing animation file in their applications. These files must be stored in standard file formats (e.g., WAV,. MID,.VOC, AND INS).

Recording and playback capability this allows users to record, play, and  pause an animation sequence.

Transition effects These effects include fade-in, rotation, layering, and zoom-in. They are used to make more interesting and realistic animations.

Text to speech recognition program This converts a written text into its equivalent sound.

Voice recognition software This identifies the speaker by matching his/her voice with the records of voice in the database.

Media centre PC most homes use a computer for performing many activities(such as browsing the web, sending emails, doing school assignments, downloading songs and movies, creating CDs, or editing pictures) and a television for entertainment that includes watching movies and shows.
