OVERVIEW
Processing is the manipulation of data. It
involves:
Integration of data
Compression and decompression of audio,
video and images
Hypermedia

CONTINUE – INTEGRATION OF
DATA
Collected data is often
imported into multimedia
software which is used to
integrate and bring together
different media data, such as
video.

CONTINUE – COMPRESSION AND
DECOMPRESSION
Compression 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.

CONTINUE – COMPRESSION AND
DECOMPRESSION
CODEC 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.
