What is MULTIMEDIA?
Multimedia is combination of
more than one media into an
information source or
Elements of Multimedia are
Adobe live motion
Quick time player
Multimedia Computer System
• It is the capability to integrate two or more
types of media ( text, graphics, images, audio
and video) for the purpose of generation,
storage, representation and access of
Requirements of Multimedia
• Faster Central Processing Unit (CPU)
• Large Storage Devices.
• Larger Main Memory.
• Good Graphics Terminals.
• Input/Output Devices.
Alphanumeric character are used to
present information in text form.
The native language of web is HTML,
which is designed to display simple text
documents on computer screen.
Hardware and Software
requirements for text
Optical Character Recognizers (OCR).
Text Importing and Exporting.
Computer graphics deals with the
generation, representation, manipulation
and display of pictures with the aid of a
Types of Graphics
• Generative Graphics
Drawings and Illustrations in the form of 2-
Dimensional and 3-Dimensional pictures
created for mathematical representation of
– Illustrative Diagrams
Computer audio deals with synthesizing,
recording and playback of audio or sound with
the aid of computer.
In Learning audio can be added to the
ANALOG AND DIGITAL
• Audio information travels in natural
medium in the form of sound waves which
are analog in nature.
• Analog Is converted in digital form by
Transducer for the computer.
Hardware and Software
• Sound Card.
• Output Device.
• Audio File Importing.
• Recording and playback capability.
• Voice Recognition software.
• Computer video deals with the recording
and display of a sequence of images at a
reasonable speed to create impression of
• Each individual image of a sequence of
images is called a Frame.
• For jerk-free full motion video 25-30
frames have to be displayed per second.
Hardware and Software
• Video Editors.
• Video Monitor.
• Video Board.
• Input Device like video camera
• Recording and Playback Capability.
• Multimedia presentation
• Distance and interactive training
• Foreign language learning
• Video games
• Animated advertisements
• Multimedia conferencing
• Special effects in films
• Multimedia kiosk
• Multimedia kiosk has a touch-screen monitor
with user friendly graphical user interface for
ease of operation by general public.
• Multimedia kiosk are often used in public
places as information providers.
• Example –
• Multimedia conferencing refers to a system
that simulates face-to-face interactions among
participating users located far from each other.
• Animation deals with the generation,
sequencing and display of a set of images to
create an effect of visual motion.
• Visual effects such as wipes ,fades, zooms and
dissolves , available in most authoring
packages , are a simple form of animation.
• Television video build 30 entire frames every
second. Movies are typically shot at a shutter
rate of 24 frames per second.
Why use Animation?
• Animation can help organize thoughts
and illustrate processes.
• Animation is useful for illustrating
concepts which involve movement.
• Teaching swimming –the proper way to
swing hands for swimming can be more
effectively illustrated with an animation.
• Flow of blood in arteries and veins can be
illustrated with the help of animation.
• The visual changes that bring an image alive
occur on the flat Cartesian x and y axes on the
• These are simple and static , not changing their
position on the screen.
• Authoring and presentation software such as
Flash or Power-point provide user friendly
tools to compute positional changes.
• An illusion of depth is added to an image
through shadowing and highlighting, but
image still rests on flat x and y axes.
• Embossing, shadowing, beveling and
highlighting provide a sense of depth by
raising an image .
• Examples are Adobe illustrator , Photoshop,
Fireworks, and After effects.
• Software creates a virtual realm in three
dimension, and changes are calculated along
all three axes.
• It allows the viewer to wander around and get
a look at all the object’s parts from all angles.
PRINCIPLES OF ANIMATION
• Animation is possible because of a biological
phenomenon known as persistence of vision
and a psychological phenomenon called phi.
• With the simplest tools you can make a
bouncing ball to animate your web-site using
• Making animations appear natural requires a
basic understanding of the principles of
Difference between animation
• Animation is commonly used in those
instances where video graphy is not possible.
• Animation can better illustrate the concept
• Example- Earth is revolving around its axis
can not be video graphed but can show
• Transformation of object shapes from one
form to another is called morphing.
• Multimedia serves us an opportunity to create
• Multimedia is used in every field
In schools ,colleges.
In day to day life.
• Multimedia will provoke radical changes in the
teaching process during coming decades, students can
discover they can go beyond the limits of traditional
