Multimedia is content that uses a combination of different content form such as
text, audio, images, animation, video and interactive content. The multimedia
may be combined with movie, presentation, interactivity, graphics or animation
to give some information which can be stored, transmitted and processed
digitally.
Components of Multimedia
Text: - Text is the basic element of multimedia. Text is
combination of alphabets symbols, digits, punctuation etc. In a multimedia
application, other media or screen can be linked through the use of text. This
is what you call Hypertext.
Graphics (Image): - A picture is a
worth of thousand words. An image, figure, picture or drawing can consider as
graphics. Graphics represent still image and defined as static representation.
Extensions are jpeg, gif, bmp, png, jpg etc. Common graphic software program
are Photoshop, paint. Net etc
For example:-
Photoshop of an employee with his/her name, sex, age, address etc from a company's
database of employee's make the employee information much more effective.
Audio: - A multimedia application may require the use of speech,
music and sound effects. These are called audio or the sound element. There are
two basic types of audio or sound: analog and digital audio. Applications of
audio service are telephone communication, telemarketing, voicemail, audio
teleconferencing, radio etc. Audio format include MP3, WMA, Wave, MIDI and
RealAudio. Soundcard, headphone, speaker, audio mixer, and microphones are used
for generating audio or sound.
Video: - Video is the
sequence of images over time. Video clips can be combined with audio, text,
graphics. Video conferencing, television, multimedia, CCTV etc are application
of video communication, Common digital video formats include flash, Mpeg, AVI,
WMV and QuickTime etc.
Animation: -
Animation is the displaying of image in a sequence to create an effect a visual
change or motion similar to a movie (video). Image generation tools such as
digital camera, scanner and video generation tools such as digital video
camera, videocassette Recorder (VCR), Digital Versatile Disk (DVD) are the
powerful tool for generating images and videos for animation. Common tools for
creating animation are Adobe flash. Example Cartoons on television.
Application of
Multimedia: Multimedia finds its application in
various areas including
1.
Entertainment
and fine arts: multimedia is heavily used in the
entertainment industry, especially to develop special
effects in movies and animations.
Multimedia games are a popular pastime and are software programs available
either as CD-ROMs or online. Multimedia applications that allow users to
actively participate instead of just sitting by as passive recipients of information
are called Interactive Multimedia. In the Arts there are multimedia artists whose minds are able to blend
techniques using different media that in some way incorporates interaction with
the viewer.
2.
Advertisement. It helps in advertisement of product for business
organization. The concept of e-commerce is not only needed online purchasing,
but advertise products amongst inter users.
3.
Education: Multimedia is used to produce computer based training courses (CBTs) and reference books like encyclopedia. CBT
lets the user go through a series of presentations, text about a particular
topic, and associated illustrations in various information formats. A large
number of university also provide also provide online degree or distance mode
of education courses for the higher education. Universities provide study
material online, students reads it in their free time by using computer, give
examination and receive university degree from their own locations.
4.
Journalism: Freelance journalists can make use of different new media to
produce multimedia pieces for their news stories. It engages global audiences
and tells stories with technology, which develops new communication techniques
for both media producers and consumers.
5.
Multimedia reporters who are mobile
(usually driving around a community with cameras, audio and video recorders,
and laptop computers) are often referred to as Mojos, from mobile journalist.
6.
Engineering Software
may use multimedia in Computer Simulations for anything from entertainment to training such as military or industrial training.
7.
Industry: Multimedia
is used as a way to help present information to shareholders, superiors and
coworkers. Multimedia is also helpful for providing employee training,
advertising and selling products all over the world via virtually unlimited
web-based technology.
8.
Mathematical
and scientific research: In mathematical and scientific research, multimedia is mainly used for modeling and simulation. For
example, a scientist
can look at a molecular model
of a particular substance and manipulate it to arrive at a new substance.
9.
Medicine: In medicine, doctors can get trained by looking at a virtual surgery or they can simulate how the human
body is affected by diseases spread by viruses and bacteria
and then develop techniques to prevent it. Multimedia applications such as virtual
surgeries also help doctors to get practical
training.
10.
Document
imaging: It is a technique that takes hard
copy of an image/document and converts it into a digital format (for example,
scanners).
11.
Disabilities:
Media allows those with disabilities
to gain qualifications in the multimedia field so they can pursue careers that
give them access to a wide array of powerful communication forms.
12.
Presentation: It is a strong medium of presentation of graphs, reports
and any other materials. The business organization, training centers, learning
all depend on effective presentation. There are tools and techniques are developing
to developed presentation kits.
13.
Virtual
reality and Simulations: Flight
simulation are used to train pilots, the external effect such as changing
weather, required high resolution image and ability to control different
aspects of the system.
14.
Training: The school, colleges, business organization etc use video
clips, slideshows to trained manpower.
15.
Information
Provision: Multimedia encyclopedia is an
example of a multimedia system used to provide information. It displays
information using text, color, audio and video or animation.
