The document outlines the essential features and requirements of multimedia systems, including high processing power, efficient file systems, and various file formats that support audio and video. It discusses the importance of a capable operating system, large storage capacity, network support, and necessary software tools for multimedia presentation. Additionally, it highlights applications of multimedia in education, commerce, and communication technology.

1. Multimedia Systems
Part 2

2. Features of Multimedia
1. Very High Processing Power: There is a need for the high processor to deal with the
large amount of data that is used in Multimedia.
2. File System: There is a need for an efficient file system that can able to run the media
continuously. To run these media files, we need very high-disk bandwidth rates with a disk
scheduler that can speed up the data transfer rate of the disk.
3. File formats that support Multimedia: There are so many file formats that are
supported by multimedia. These file extensions are - JPEG, MPEG, AVI, MID, WAV, DOC,
GIF, and PNG. A file format known as AVI contains both audio and video files. It allows
the play of audio and video simultaneously. But there is a restriction on the conversion of
one format to another format.
4. Input or Output: The input or output system should be very fast in nature. The
information or output should be efficient to play both the playback and recording
simultaneously.

3. Features of Multimedia
5. Operating system: There is a need for a high-speed operating system that responds
very fast.
6. Storage and memory: A Multimedia system needs a large amount of storage space in
which all the audio, video, animation and text should be saved.
7. Network support: Multimedia supports network systems like Local Area Network
(LAN), Wide Area Network (WAN), internet, intranet, mobile telephony, and so on. These
multimedia networking applications are referred as continuous-media applications and
require high communication latency. Communication Latency is the time it takes for a data
packet to be received by the remote computer.
8. Software tools: There is a need for various software tools that are used to prepare a
multimedia presentation like multimedia editing software, programming language and
graphics software,

4. Multimedia Hardware
 Most of the computers now-a-days come equipped with the
hardware components required to develop/view multimedia
applications.
 Processor: The heart of any multimedia computer is its
processor. Today Core i5 or higher processor is recommended for
a multimedia computer.
 Memory and Storage Devices - You need memory for storing
various files used during production, original audio and video
clips, edited pieces and final mined pieces. You also need
memory for backup of your project files.

5. Multimedia Hardware
 Input Devices - Following are the various types of input devices
which are used in multimedia systems. (Keyboard, mouse, joystick,
light pen, track ball, scanner, Digitizer, Magnetic Ink Card
Reader (MICR), Optical Character Reader (OCR) , Bar Code
Readers , Optical Mark Reader (OMR) , Voice Systems , Digital
Camera, Digital Video Camera)
 Output Devices - Following are few of the important output devices,
which are used in Computer Systems(Monitors, Printers, Screen
Image Projector , Speakers and Sound Card )

6. Multimedia Software
 Multimedia software tells the hardware what to do. For
example, multimedia software tells the hardware to
display the color blue, play the sound of cymbals
crashing etc.
 There are various software available in the market such
as Paint Brush, Photo Finish, Animator, Photo Shop, 3D
Studio, Corel Draw, Sound Blaster, IMAGINET, Apple
Hyper Card, Photo Magic, Picture Publisher.

7. Multimedia Software Categories
 Device Driver Software- These software are used to install and configure the
multimedia peripherals.
 Media Players- Media players are applications that can play one or more kind
of multimedia file format.
 Media Conversion Tools- These tools are used for encoding / decoding
multimedia contexts and for converting one file format to another.
 Multimedia Editing Tools- These tools are used for creating and editing
digital multimedia data.
 Multimedia Authoring Tools- These tools are used for combing different
kinds of media formats and deliver them as multimedia contents.

8. Area of Multimedia Applications
 Electronic Encyclopedia
- For example, there are available encyclopedia that contain video programs
depicting animal behaviors and other natural phenomena.
- One advantage of the electronic medium is the huge storage capacity that it
offers at very low cost.
 Education
- For example, medical schools use multimedia-simulated operations that enable
prospective surgeons to perform operations on a computer-generated "virtual"
patient.

9. Area of Multimedia Applications
 Commerce
- Multimedia is also used in commercial applications. Multimedia games allow players to
race Indy cars or battle each other from the cockpits of giant robots.
- Also architects and designers use multimedia presentations to give clients tours of houses
that are not even built yet.
 Communication Technology and Multimedia Services-
- These services may include:
Basic Television Services, Interactive entertainment, Digital Audio, Video on demand,
Home shopping, Financial Transactions, Interactive multiplayer or single player games,
Digital multimedia libraries, E-Newspapers, e-magazines.
