Hardware and software requirement for multimedia

The components which display the data or information that has been processed by the CPU are the output devices. Examples of main output devices are the monitor, speaker, and printer. Multimedia software tools Multimedia Software Tools. The basic tool set for building a multimedia project can be divided into five categories: — Painting and Drawing Tools — 3-D Modeling and animation tools — Image editing tools — Sound editing tools — Animation Video — Digital Movie tools.

Multimedia has become a huge force in human-being culture, industry and education. Multimedia is heavily used in the entertainment industry, especially to develop special effects in movies and animations VFX, 3D animation, etc.

Multimedia games are a popular pastime and are software programs available either as CD-ROMs or online. Some video games also use multimedia features. History of Multimedia Systems. Newspaper were perhaps the first mass communication medium to employ Multimedia -- they used mostly text, graphics, and images.

In , Gugliemo Marconi sent his first wireless radio transmission at Pontecchio, Italy. Educational multimedia applications are used to improve learning effectiveness. A multimedia learning environment involves numbers of elements in order to enable learning process taking places. Audio allows students to use their imagination without being biased, so it will greatly increase the learning outcome. The list of hardware components required in multimedia computer are as follows: Microprocessor. High storage hard disk.

High resolution graphics cards. Optical disk drive etc. The basic invention of technology has made our lives much simpler than it was before. Importance of Multimedia. Free Multimedia Software. VLC media player. A finite number of characters can be displayed on a screen at once.

The screen can be divided into a series of character boxes - fixed location on the screen where a standard character can be placed. Most screens are capable of displaying 80 characters of data horizontally and 25 lines vertically.

Flat-Panel Display Monitor - The flat-panel display refers to a class of video devices that have reduced volume, weight and power requirement compared to the CRT.

You can hang them on walls or wear them on your wrists. Current uses for flat-panel displays include calculators, video games, monitors, laptop computer, graphics display.

The flat-panel displays are divided into two categories: Emissive Displays - The emissive displays are devices that convert electrical energy into light. Non-Emissive Displays - The Non-emissive displays use optical effects to convert sunlight or light from some other source into graphics patterns.

Printers - Printer is the most important output device, which is used to print information on paper. Dot Matrix Printer - In the market, one of the most popular printers is Dot Matrix Printer because of their ease of printing features and economical price. Daisy Wheel - Head is lying on a wheel and Pins corresponding to characters are like petals of Daisy flower name that is why it is called Daisy Wheel Printer.

These printers are generally used for word-processing in offices which require a few letters to be send here and there with very nice quality representation. Laser Printers - These are non-impact page printers.

They use laser lights to produce the dots needed to form the characters to be printed on a page. Inkjet Printers - Inkjet printers are non-impact character printers based on a relatively new technology.

They print characters by spraying small drops of ink onto paper. Inkjet printers produce high quality output with presentable features. They make less noise because no hammering is done and these have many styles of printing modes available. Colour printing is also possible. Some models of Inkjet printers can produce multiple copies of printing also. Screen Image Projector - Screen image projector or simply projector is an output device used to project information from a computer on a large screen so that a group of people can see it simultaneously.

A presenter first makes a PowerPoint presentation on the computer. Now a screen image projector is plugged to a computer system and presenter can make a presentation to a group of people by projecting the information on a large screen.

Projector makes the presentation more understandable. Speakers and Sound Card - Computers need both a sound card and speakers to hear audio, such as music, speech and sound effects.

Most motherboards provide an on-board sound card. This built-in-sound card is fine for the most purposes. The basic functions of a sound card are that it converts digital sound signals to analog for speakers making it louder or softer.

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. To produce these media elements movies, sound, text, animation, graphics etc. Device Driver Software - These softwares 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. 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.

Target audience 3. Set the content 4. Estimating cost 5. Hardware 6. Software 7. Build a multimedia team Define the objectives and scope What is the purpose of creating the project? Define the scope or the boundary of the project. If we decrease any of these elements, we may generally increase one or both of the others. People Time Money It will take longer time to develop multimedia application if developer team people and money is less.

People Time Money If there is a large number of developer team, time and money cost to develop multimedia application could be reduced. Time Money People Money cost can be saved if we decrease the number of developer team and time duration in multimedia application development. However, there are software that can help to save time and to organize a project which are less expensive. Each person has their own specialized skills required to do specific task.

Installation should be smooth, easy and fast. TXT is good thing to include in the CD distribution of your project. Summary 1.

Resolution is the amount of details the monitor can render.

Resolution is defined in terms of horizontal and vertical pixel picture elements displayed on the screen. We need to convert the analog video signal to digital signal for processing in a computer. Normal computer will not be able to do it alone. It requires special equipment called video grabbing card and software to this conversion process. This card translates the analog signal it receives from conventional sources such as a VCR or a video camera, and converts them into digital format.

Not only you can use computer to compose your own music, but it can also be used for recognition of speech and synthesis. It can even read back the entire document for you. But before all this happens, we need to convert the conventional sound signal to computer understandable digital signals. This is done using a special component added to the system called sound card.

CD-ROM is a magnetic disk of 4. It has become a standard by itself basically for its massive storage capacity, faster data transfer rate. For the creation of multimedia on the PC there are hundreds of software packages that are available from manufacturers all over the world.

Adobe CS4 is a collection of graphic design, video editing, and web development applications made by Adobe Systems many of which are the industry standard that includes.
