Concept about Multimedia

Multimedia is content that uses a combination of different content forms such as text, audio, images, animations, video and interactive content. Multimedia contrasts with media that use only rudimentary computer displays such as text-only or traditional forms of printed or hand-produced material.

Multimedia can be recorded and played, displayed, interacted with or accessed by information content processing devices, such as computerized and electronic devices, but can also be part of a live performance. Multimedia devices are electronic media devices used to store and experience multimedia content. Multimedia is distinguished from mixed mediain fine art; for example, by including audio it has a broader scope. The term “rich media” is synonymous with interactive multimedia.

Students from starting only are getting in touch with computers so that they can be friendlier with them in their later stages.
3. Engineering	Software engineers may use multimedia in computer simulations for anything from entertainment to training such as military or industrial training.
4. Mathematical and scientific research	In mathematical and scientific research, multimedia is mainly used for modeling and simulation.
5. 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
6. Commercial uses	Much of the electronic old and new media used by commercial artists and graphic designers is multimedia Exciting presentations are used to grab and keep attention in advertising.

Types/Elements of Multimedia:

1. Text
2. Audio Sound
3. Static Graphics Images
4. Animation
5. Full-Motion Video

Let’s look at each of these components in more detail.

A. Text: Text is the basis for word processing programs and is still the fundamental information used in many multimedia programs.

B. Audio Sound: The integration of audio sound into a multimedia application can provide the user with information not possible through any other method of communication

C. Static Graphics images: There is no movement in these types of picture. Static graphics images are an important part of multimedia because humans are visually oriented. As the old Chinese proverb goes, “A picture is worth a thousand words. “Windows is also a visual environment.

D. Animation: Animation refers to moving graphics images. The movement of somebody giving CPR makes it much easier to learn cardiopulmonary resuscitation, rather than just viewing a static picture.

E. Full-Motion Video: Full-motion video, such as the images portrayed in a television, can add even more to a multimedia application.

Definition of Multimedia Computer System:

A multimedia computer system is a computer having capability to integrate two or more types of media (text, graphics, image, audio, and video) for generation, storage, representation, manipulation, and access of multimedia information.

Components of a Multimedia System:

Now let us consider the Components (Hardware and Software) required for a multimedia system:

1. Capture devices	Video Camera, Video Recorder, Audio Microphone, Keyboards, mice, graphics tablets
2. Storage Devices	Hard disks, CD-ROMS, Jazz/Zip drives, DVD, etc
3. Communication Networks	Ethernet, Token Ring, FDDI, ATM, Intranets, Internets.
4. Computer Systems	Multimedia Desktop machines, Workstations, MPEG/VIDEO/DSP Hardware
5. Display Devices	CD-quality speakers, HDTV, SVGA, Hi-Res monitors, Colour printers etc.

The main mediums of Multimedia

There is a well-wide preferences for computers and they tend to replace the conventional machines.

1. Text: Any work is relation to written text is world-wide done on computers. Once it was done by the typewriter. At present, computers are used for all kinds of writing tasks in offices to professional printing houses.

2. Graphics: Computers are used for graphics design, editing, and so on. In our country, the use of computer is very limited in graphics design, painting, drawing, and even in commercial graphics included in Fine Arts. However, computers are widely used in printers and packaging industries. The use of computer started in 1990s in printing, publication and graphics design. It was first used in editing scanned photos by Photoshop. Gradually, computers have been used in design and graphics.

Video: Video is a kind of graphics. It is better to call it a moving graphics. Video is an established medium all over the world. Video has been extensively used in TV, Home Video, Multimedia Software, Web, etc.
Animation: Animation is a kind of graphics. But it can be either moving or static. It can be either 2D or 3D. The use of animation is gradually increasing in our country. In advertisement, animation is a favourite media, but we lack skilled people in this sector. In fact, animation is never used as a single medium. It is combined with audio, video, text, graphics, etc.

3. Sound or Audio: The whole world depends on computer for sound or audio recordings, editing, etc. Analogue system has completely been obsolete in sound engineering. Now sound recording can easily be done in computers.

Use of Multimedia in ICT

There is an increased use of multimedia in ICT.

➤ As teaching aid: The use of multimedia as a teaching aid is widely used. The learners will understand a topic easily if multimedia is used in the class room. The teacher can easily make the lesson effective and interactive. Besides this, there is multimedia software for education.

Multimedia technology has been used in with ‘Bangladesh-71’, ‘Abosor’, ‘Biswakosh’, ‘Namajshiksha’, ‘Bijoy Shishushiksha’, etc. They are not much interactive. However, we expect that in Bangladesh, multimedia software will be definitely developed extensively in the 21st Century.
Digital Publication: Our publication is still paper-based, but 21st century will definitely be the century of digital publication.

➤ Entertainment: Multimedia is widely used in most of the genres of entertainment. Cinemas and plays are being made livelier by the special effects of multimedia.
