OVERVIEW

Processing is the manipulation of data. It involves:

Integration of data

Compression and decompression of audio, video and images

Hypermedia

CONTINUE – INTEGRATION OF DATACollected data is often

imported into multimedia

software which is used to

integrate and bring together

different media data, such as

video.

CONTINUE – COMPRESSION AND DECOMPRESSIONCompression reduces the

number of bits required to

represent information.

Compressed data is

decompressed to extract the

original information.

CONTINUE – COMPRESSION AND DECOMPRESSION

Images are often stored in the following formats. The difference

between the two is the colour support.

GIF – limited to 256 colours

JPEG – uses full spectrum of 16.7 million colours.

CONTINUE – COMPRESSION AND DECOMPRESSIONCODEC encodes and decodes data.

Typically used for sound and video

files. Converts analog signals into

compressed video files, such as

MPEG, or analog sound signals into

digitised sound, such as RealAudio.

CONTINUE - HYPERMEDIA

Involves linking of

information in different types

of media. Information is

stored using a set of

documents. Information is

retrieved using hypertext.

CONTINUE - HYPERMEDIA

Most well-known application of hypermedia and hypertext

is the Web.

SUM-IT-UP

Processing is therefore and integral part of a multimedia

system. It allows various methods for users to implement

during their production of the system, such as integration of

data.
