25. Disadvantages of Multimedia 1.Expensive 2.Not always easy to configure 3.Requires special hardware 4.Not always compatible Eyad Alshareef 25

26. Multimedia Categories Linear Non-Linear Eyad Alshareef 26

27. Linear VS Non-Linear  A Multimedia Project is identified as Linear when:  It is not interactive  User have no control over the content that is being showed to them.  Example:  A movie  A non-interactive lecture / demo show Eyad Alshareef 27

28. Linear VS Non-Linear  Linear active content progresses without any navigation control for the viewer such as a cinema presentation Eyad Alshareef 28

29. Eyad Alshareef 29

30. Linear VS Non-Linear  A Multimedia Project is identified as Non-Linear when:  It is interactive  Users have control over the content that is being showed to them.  Users are given navigational control  Example:  Games  Courseware  Interactive CD Eyad Alshareef 30

31. Linear VS Non-Linear  Multimedia Categories Non-linear content offers user interactivity to control progress as used with a computer game or used in self- paced computer based training. Eyad Alshareef 31

32. Eyad Alshareef 32

33. Multimedia Categories Multimedia presentations can be live or recorded. A recorded presentation may allow interactivity via a navigation system. A live multimedia presentation may allow interactivity via interaction with the presenter or performer. Eyad Alshareef 33

34. Multimedia Systems  A Multimedia System is a system capable of processing multimedia data and applications. Eyad Alshareef 34

35. Multimedia Systems A Multimedia System is characterized by –The processing –Storage –Generation –Manipulation –Rendition of Multimedia information. Eyad Alshareef 35

36. Multimedia System  Characteristics of a Multimedia System  A Multimedia system has four basic characteristics: 1. Multimedia systems must be computer controlled. 2. Multimedia systems are integrated. 3. The interface to the final presentation of media is usually interactive 4. The information they handle must be represented digitally. Eyad Alshareef 36

37. Multimedia System 1.ComputerControlled Producing the content of the information–e.g.by using the authoring tools, image editor,sound and video editor Storing the information–providing large and shared capacity for multimedia information. Transmitting the information–through the network. Presenting the information to the end user–make direct use of computer peripheral such as display device (monitor)or sound generator(speaker). Eyad Alshareef 37

38. Multimedia System  2.Integrated  All multimedia components (audio, video, text,graphics) used in the system must be some how integrated.  Every device, such as microphone and camera is connected to and controlled by a single computer.  A single type of digital storage is used for all media type.  Video sequences are shown on computer screen instead of TV monitor. Eyad Alshareef 38

39. Multimedia System  3.Interactivity  Level1:Interactivity strictly on information delivery. Users select the time at which the presentation starts, the order, the speed and the form of the presentation itself.  Level2:Users can modify or enrich the content of the information, and this modification is recorded.  Level3:Actual processing of users input and the computer generate genuine result based on the users input. Eyad Alshareef 39

40. Multimedia System  4.Digitally Represented  Digitization: process involved in transforming an analogue signal to digital signal. Eyad Alshareef 40

41. Components of a Multimedia System  Capture devices/Input Devices –Keyboard, scanner, video camera  Storage Devices –Hard disk, optical disc  Communication Network –Modem, network card, cables  Computer System –CPU, RAM, Display card  Display Devices –Monitor, Projector, Printer Eyad Alshareef 41

42. What is Multimedia Application? Any computer application that contain or use Multimedia elements. A multimedia applications more like a movie or a book. Content must be created and produced. Usually interactive. Eyad Alshareef 42

43. Examples of Multimedia Application  World Wide Web  Hypermedia courseware  Computer-based Training (CBT)  Interactive TV  Computer Games  Virtual reality  Multimedia Database systems Eyad Alshareef 43

44. Delivering Multimedia  Multimedia can be delivered using –Optical disk (CD-based) –Over a distributed network (Web-based) Eyad Alshareef 44

45. Delivering Multimedia  Optical Disks  The most cost-effective method of delivery for multimedia materials.  These devices are used to store large amounts of some combination of text, graphics, sound, and moving video Eyad Alshareef 45

46. Delivering Multimedia  Distributed Network  Suitable for web-based content eg. website  Files need to be compress be for transfer Eyad Alshareef 46

47. Delivering Multimedia Eyad Alshareef 47 Network BasedCD based (DVD) Limited in picture size and low video resolution Can store high end Multimedia elements Can be changes, damaged or deleted by irresponsible individuals Can be permanently stored and not changeable Information can be updated easily and cheaper Information can be quickly outdated

48. Hypermedia and Multimedia  A hypertext system : meant to be read nonlinearly, by following links that point to other parts of the document, or to other documents.  Hypermedia : not constrained to be text-based, can include other media, e.g., graphics, images, and especially the continuous media - sound and video.  The World Wide Web (WWW) - the best example of a hypermedia application. Eyad Alshareef 48

49. Multimedia Authoring Tools that provide the capability for creating a complete multimedia presentation, including interactive user control, are called authoring programs. - Macromedia Flash: allows users to create interactive movies by using the score metaphor, i.e., a timeline arranged in parallel event sequences. - Macromedia Director : uses a movie metaphor to create interactive presentations. It is very powerful and includes a built in scripting language, Lingo, that allows creation of complex interactive movies. Eyad Alshareef 49

50. Multimedia Authoring -Authorware: a mature, well-supported authoring product based on the Iconic/Flow-control metaphor. - Quest: similar to Authorware in many ways, uses a type of flowcharting metaphor. However, the flowchart nodes can encapsulate information in a more abstract way (called frames ) than simply subroutine levels. Eyad Alshareef 50
