ANIMATION

Is the technology of capturing, recording, processing, transmitting, and reconstructing moving pictures.

Video is more towards photo realistic image sequence / live recording as in comparison to animation.

Video also takes a lot of storage space. So plan carefully before you are going to use it.

Interactive Multimedia

When the user is given the option of controlling the elements.

Hyper MediaA combination of hypertext, graphics,

audio, video, (linked elements) and interactivity culminating in a complete, non-linear computer-based experience.

Catagorization of Multimedia

A Multimedia Project is identified as Linear when: It is not interactive User have no control over the content that is being

showed to them. Example:

A movie A non-interactive lecture / demo show

LINEAR

Catagorization of Multimedia

A Multimedia Project is identified as Non-Linear when: It is interactive Users have control over the content that is being showed to

them. Users are given navigational control

Example: Games Courseware Interactive CD

NON-LINEAR

Authoring Tools

Designed to manage individual multimedia elements and provide user interaction (if required).

Authoring Tools

Importance of Multimedia

There are a number of fields where multimedia could be of use. Examples are:-BusinessEducationEntertainmentHomePublic Places Medical Institutions

Hypertext • Hypertext is a system of storing images,

text, and other computer files that allows direct links to related text, images, sound, and other data.

Hypertext• Hypertext is the main basis of operation

for the web.• The term "hypertext" was coined by TED

NELSON, who defined it in his self-published Literary Machines as "non-sequential writing"

Hypertext

Hypertext is the presentation of information as a liked network of nodes which readers are free to navigate in a non-linear fashion. It allows for multiple authors, a blurring of the author and reader functions, extended works with diffuse boundaries, and multiple reading paths

Hypertext links called hyperlinks create a complex virtual web of connections for users.

Hypertext, at its most basic level, is a DBMS that lets you connect screens of information using associative links

Hypertext is a software environment for collaborative work, communication, and knowledge acquisition. Hypertext products mimic the brain's ability to store and retrieve information by referential links for quick and intuitive access

Hypermedia

Hypermedia is a style of building systems for organising, structuring and accessing  information around a network of multimedia nodes connected together by links.

Hypermedia

We can distinguish hypermedia systems in two generations

 First generation hypertext systems were  mainframe based, text-only systems for augmenting the performance of information processing environments, storing the whole world's literature or for supporting traditional writing and reading. 

Transition from hypertext to hypermedia took place with the Second Generation Systems.
