the paths the user need to follow for the text access

in non-sequential ways.

 The user is permitted to define their own paths in

more sophisticated hypertext systems.

Image:

 Images acts as an vital component in multimedia.

 These images are generated by the computer in two

ways, as bitmap or raster images and as vector

images.

Animation:

 Animation is the process displaying still images so

quickly so that they give the impression of

continuous movement.

 Animations may be in two or three dimensional.

Path Animation:

 Path animation involves moving an object on a

screen that has a constant background.

 E.g. a cartoon character may move across the screen

regardless of any change in the background or the

character.

Frame Animation:

 In frame animations, multiple objects are allowed to

travel simultaneously and the background or the

objects also changes.

Musical Instrument Digital Identifier (MIDI):

 Musical Instrument Digital Identifier (MIDI) is a

standard communication tool developed for

computers and electronic instruments.

 This tool is flexible and easy for composing the

projects in multimedia.

Digital Audio:

 Sampled sound is a Digitized sound.

 A sample of sound is taken and stored every nth

fraction of a second as digital information in bits

and bytes.

Video :

 Video is defined as the display of recorded event,

scene etc. The powerful way to convey information in

multimedia applications is embedding of video.

 The video can be categorized in two types as Analog

video and Digital video.

Image Formats:

TIFF (Tagged Image File Format):

 (high quality output)

computer color images and backgrounds are GIF

files.

JPEG (Joint Photographic Experts Group):

 JPEG was designed to attain maximum image

compression. It uses lossy compression

technique, where a compression method is referred

that loses some of the data required for the image

reconstruction.

TGA (tagra)

 It is the first popular format for high resolution

image. its supported by most of the video capture

boards.

PNG (portable network graphics)

An extensible file format for the less loss.

Well compressed storage of raster image .

PNG act as replacement for GIF and also replace

multiple common uses of TIFF.

 It s work good online viewing applications like

worldwide web.
