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.
