3. Define Multimedia
 Multimedia contains multiple elements such
as text, image, audio and videos used in a
single platform.
 Static Elements – Text and image
 Dynamic Elements – Audio, Video ,Animation

4. Components of Multimedia
 Static Elements : They are fixed and non
movable but shares information to the other.
 Dynamic Elements : They are changeable
and motional, and shares a range of
information

5. Text Elements
 Two types
 Static Text : In static text the words will
either
give information or support an image or
an video .
 Hyper Text :the text and the links
between the nodes, which defines the
paths the user need to follow for the
text access in non-sequential ways.

6. Images
 Raster Images : Simple Matrix of tiny dots
called pixels, Merged to form a bitmap
images or raster images. E.g.: 1bit = 2 colors
 Vector Images : Drawing Elements ,Such as
rectangle, circle and square.
 Uses compression techniques to reduce the
size of images and speed up transfer.
 GIF, TIFF and JPEG

7. Animation
 Two Dimensional : X & Y axis
 Three Dimensional : X,Y & Z axis
 Purely focus on live image.
 16 frames – Smoothness
 25 frames – Natural Looking
 Animation Two Types :
 Path Animation : Moving object with constant
background E.g. : Cartoon Character or Games
 Frame Animation : Simultaneous Moving of object
and background changes drastically . E.g. : Movies

8. Sound
 Written Text replaced with audible or hearable
transfer of information, with music and with added
special effect.
 Decibels is the measurement of volume, the
pressure level of sound.
 MIDI (Musical Instrumental Digital Identifier)
 Tools for synthesizing the sound.
 Digital Audio
 A sample of sound is taken and stored every nth
fraction of a second in form of bit and bytes.
 Quality – Sampling Rate -bit depth, resolution and
sample size.

9. Video
 The display of recorded events or scene
 Two Types : Analog ,Digital
Analog Video : the video data’s are stored in
any non-computer media like video tape,
laserdisc, film.
 Composite and Component Analogue Video :
brightness, color, and synchronization combined
into one signal.
 color blending, low clarity and high generational
loss, Betamax and VHS.

10. File Formats for
Multimedia
 Text Formats
 RTF(Rich Text
Format),1987,Microsoft,Document
Interchange
 Plain Text : Opened , read and edited by
most editors.
 Notepad(Windows) ,Gedit & Nano(Unix and
Linux)
 conveying an e-mail.

11. Image Formats
 TIFF (Tagged Image File Format) high
quality output, image compression and
Comfortable moving large files.
 BMP (Bitmap) quite large and
uncompressed, high quality occupies large
size.
 DIB (Device Independent Bitmap) similar to
BMP, allows the files to be displayed on a
variety of devices

12. Image Formats
 GIF (Graphics Interchange Format) compressed image format,
best suitable for graphics that uses only limited colors, online
color photos - 13-bit Color
 JPEG (Joint Photographic Experts Group) maximum image
compression.
 Lossy compression technique - loses some of the data required for the
image reconstruction.
 works good with photographs, naturalistic artwork
TGA (Tagra)
 first popular format for high resolution images, Most of the video-
capture boards
 PNG (Portable Network Graphics) less loss, portable and well
compressed storage. works good with online viewing
applications like worldwide web

13. Digital Audio File Formats
 WAV (Waveform Audio File Format) most popular
audio file format in windows for storing uncompressed
sound files, can also be converted to other file formats.
 MP3 (MPEG Layer-3 Format) MPEG Layer-3 format
for storing and downloading music, one-tenth the size
of an equivalent WAV file.
 OGG A free, open source container format, better
streaming and evolving at high end quality digital
multimedia.
 AIFF (Audio Interchange File Format) standard audio
file format used by Apple, Like wav format.

14. Digital Audio File Formats
 WMA (Windows Media Audio) windows
media audio format owned by Microsoft and
designed with Digital Right Management
(DRM) abilities for copyright protection.
 RA (Real Audio Format) designed for
streaming audio over the Internet, usually
stored as a computer file in computer’s hard
drive or CD/DVD.

15. Digital Video File Formats
 AVI (Audio/Video Interleave) sound and picture
elements are stored in alternate interleaved.
 MPEG (Moving Picture Experts Group) generating
digital video and audio compression under the
International Standards Organization(ISO) By group of
people.
 MPEG-1 - Video CD and MP3 based
 MPEG-2 - Digital Television set top boxes and DVD
 MPEG-4 – Multimedia and Mobile Web
 MPEG-7 - search of audio and visual content
 MPEG-21 – Multimedia Framework –started on
2000,standards for digital video and audio compression.
