  1. Unit 3: Multimedia The Development Process

  2. What is Multimedia? • An interactive piece of software using several types of media: • Text • Graphics(photographs or illustrations) • Audio(synthesised or digitised) • Video • Animation • Multimedia Applications can be: • Linear or non-linear • Simple or extremely complex • For example: • PowerPoint presentation • Sophisticated and basic web pages • Multimedia games

  3. Analysis Design Implementation Testing Documentation Evaluation The Development Process/Cycle Design may change if application does not work as expected Maintenance

  4. Analysis Stage • This stage is make it absolutely clear what the project is supposed to do. • The aims of the application • Who will be using it? • What will be in it? • How will it be distributed? • How much money can be spent? • How long have you got? • Input/output? • At the end of the stage a requirements specification will be produced.

  5. Design Stage • Navigation structure? • The HCI (Human Computer Interface) • What does each screen look like? • What media elements will be included? Storyboards may be produced for this.

  6. Implementation Stage • Make it: • Create and combine all the media elements using the pre-decided authoring software. Testing Stage • Does each screen and link work as expected? • If not can it be fixed or does it have to have the design altered.

  7. Documentation Stage • Write the documentation: • The technical guide • What are the hardware requirements • The user guide • Advice on how to use the software and provide users with any other help.

  8. Evaluation Stage • Does it meet the specifications made at the analysis stage? Maintenance Stage • Fixing any bugs that have been found after its released. • Adapting and updating the application to suit clients needs.

  10. Analysis Design Implementation Testing Documentation Evaluation Maintenance The Development Process mnemonic A Dance In The Dark Every Monday

  11. Methodologies used in creation of multimedia applications Text editor: • Application is created using plain text • e.g. Creating simple web pages using HTML. WYSIWIG editors: • Previewing applications under development to check that What You See Is What You Get. • Eg PowerPoint to create a presentation

  12. WYSIWYG

  13. Text Editor

  14. WYSIWYG Vs Text Editors

  15. Methodologies used in creation of multimedia applications Authoring Software • Application can be customised using: • Program code or scripting • Icon based setting up of properties (without the need to learn programming code) Presentation Software • Enables the creation of a sequence of slides • Allows hyper linking to different slides or files

  16. Methodologies used in creation of multimedia applications • Who makes authoring software? • Macromedia • Flash, Dreamweaver and Director • Microsoft • FrontPage • Adobe • GoLive • Others • Mediator, HyperStudio, etc

  17. Methodologies used in creation of multimedia applications • Who makes presentation software? • Microsoft • PowerPoint (Most common) • Others • LiquidMedia • Cre8 • Many others exist but not common

  18. Authoring Vs Presentation

  19. Unit 3: Multimedia The Development Process

  20. Displaying Multimedia Data Distribution Medium • Web pages on the Internet • Web pages on an Intranet • CD-ROM • DVD • Digital Broadcast System

  21. Displaying Multimedia Data Embedded Data • Applications include files for sound, video etc • These are combined (embedded) into the actual program file itself

  22. Displaying Multimedia Data Streamed data • Data broadcast over a network • radio stations broadcast over the Internet • View film clips • Played as it is received • No need to download entire file before listening/viewing it • Requires a plug in e.g. Real Player
