Each hardware has its own functions.
1) Scanners are used to convert conventional
images, texts, drawings and photos into digital form
that can be understood by the computer.
2) Video cameras: analog video camera and digital
video camera (DV).
An analog video camera records video in analog
signals on a magnetic video tape.
A digital video camera records video in digital signals,
which can be stored in various forms of media, such
as digital video tape or memory cards.

Authoring Tools
is a program that helps you write multimedia
applications.
usually enable you to create a final application

Time Frame
Concept
With time frame concept authoring tools, the
multimedia elements or events are presented
and organised along a time line.
This type of tool helps users coordinate when
each multimedia element (text, graphics,
audio, video or animation) plays.
In time frame concept authoring tools, a
timeline consists of layers which span several
frames.

Icon Concept
The
icon concept in authoring tools
provides the multimedia developer with
a visual programming approach to
sequencing events in the multimedia
application.
In this concept, elements and events are
organised in a structural framework.
