  • 1. CHAPTER 4MULTIMEDIA
  • 2. 1.0 MULTIMEDIA CONCEPT• Multimedia is presentation of information by using a combination of text, audio, graphic, video and animation.• Multimedia means more than the use of various media.
  • 3. 1.2 THE USE OF MULTIMEDIA IN VARIOUS FIELDFIELD CONTRIBUTION TO SOCIETYSource of Multimedia is use as common source ofreference reference. Encyclopedias, directories, dictionaries and electronic books are among common multimedia references.Education Learning has become more interesting and effective with educational programmes such as “edutainment” that is a combination of education and entertainment.Entertainment Beside that, multimedia is greatly used in entertainment industry. These industries produce computer games, and develop animations or special effects for cartoon and movies
  • 4. FIELD CONTRIBUTION TO SOCIETYScientific Multimedia applications are also widely used inresearch Scientific Research. For example, from research, new findings can help the researchers to improve the condition of sick peopleBusiness Multimedia applications are used in advertising products. Many companies nowadays develop and distribute catalogues in the form of a CD- ROM as it is more interesting to the consumersArt In art, artist use multimedia elements by combining drawing and animationMedicine In medicine, doctors can practice or be trained in performing high-risk surgery by using virtual surgery
  • 5. FIELD CONTRIBUTION TO SOCIETYEngineering In engineering, Computer-Aided Design or CAD is used. By using this application, engineers can view the design from many aspects and improve on it before production
  • 6. INTERACTIVITY OF MULTIMEDIA• Interactivity refers to the interaction between user and a multimedia application. The user can use input devices such as keyboard, joystick or mouse to interact with the application through the computer.• 2 types of interactivity of multimedia: ▫ Linear interactivity ▫ Non-linear interactivity
  • 7. Linear interactivity• The user interacts with the multimedia application without controlling the progress of the content. In the other words, the user is a passive receiver of the multimedia content most of the time. The linear content is usually arranged in sequence. An example of the multimedia linear content is a movie.
  • 8. Non-linear interactivity• Allows the user to interact with the content according to what the user wants from the content. Multimedia become interactive when application gives the user control over what information is viewed and when it is viewed. Non-linear interactivity uses tools like hypertext to connect a word or a phrase to another screen and hypermedia to connects different media elements such as audio, animation and video.
  • 9. Differences between Linear and non-linear multimediaLinear Different Non-linearinteractivity interactivityLinear interactivity Controlling sequence Non-lineardoes not allow the interactivity lets theuser to control the user control thesequence of the sequence of themultimedia content multimedia contentNot interactive Interactivity Interactivee.g. Examples e.g.i) Documentary i) Electronic bookii) Movie ii) Edutainmentiii)Video clip software iii)Electronic encyclopedia
  • 10. Medium of delivery• Generally, there are two very common mediums used in delivering multimedia contents : web based multimedia and CD-based multimedia.
  • 11. Web based multimedia deliveredmedia through web pages• Web-based multimedia is a combination of multimedia technology and Internet technology. With the advancement of both technologies (multimedia & internet), most web pages integrate elements like text, graphic, audio, video and animation. These dynamic elements make the process of distributing information through the internet more interesting and effective to the user.
  • 12. CD based multimedia delivered multimediathrough compact discs.• CDs like CD-ROM have been used to store and deliver multimedia content.• The advantages stored information on CD rather than printed material such as book, encyclopedia, etc. i. We can get information faster ii. We can get information easily iii. The weight of CD is very light contrast to 26 volumes of Britannica encyclopedia.
  • 13. Web based v/s CD-based Web-based Criteria CD-based Store low Resolution Store highresolution picture resolution picture and video and video (high end)Can be changed or Contents Can be deleted by permanently irresponsible stored and are not individuals changeable Information for Update Information on amultimedia can be multimedia can be updated easily quickly outdated

  • 18. HARDWARE FUNCTIONAudio devices Audio devices are devices that convert sound waves into electrical energy. The sounds are then changed into digital sound. Examples of devices used for recording sounds or audio are microphone, sound card, voice synthesizer and keyboard.Video capture Video capture device is a device that enablesdevices you connect a video camera to a computer. They help to transfer video from video camera to the computer so that the data can be edited or stored (manipulate). Examples of video captures devices are: 1. Video capture card 2. Fire wire 3. USB cable
