  1. What is Multimedia? Module Introduction

  2. Module Team

  3. The Future of Multimedia • Technology directly interfacing with our nervous system • Track down a copy of Black Mirror – History of You

  4. Immersive Sensory Experiences • Sight • Sound • Touch • Smell • Taste • Multimedia will become a fully immersive experience that takes over all of our senses

  5. Ethical Considerations • Will it come with an off button? • Will we have adverts pumped directly into our heads? • Will everything we do be monitored and tracked? • Might we get hacked? • These are important questions that don’t just relate to the above future scenario they are questions that we need to think about in the here and now.

  6. So what is Multimedia? • Depends who you are… • PC Vendor • PC with sound & video • Consumer Entertainment • Cable TV • Smart TV • Online service – Netflix • Developer • Applications for authoring multimedia • Text, graphics, animation, video and sound • Plus interactivity • Convergence – many technologies and disciplines coming together e.g. • Programming • Human computer interaction • Graphic design

  7. Potential Applications • Video conferencing – Skype • Distance learning – Open University • Cooperative applications – Google docs / on-line games • Augmented reality – Google glass (Last sighted in a local CEX store) – Oculus rift • So many areas of Computing impacted by multimedia

  8. Technical Aspects • Processing and Encoding • How to store images and video efficiently yet still preserving quality • System integration and Networking • Protocols and hardware allowing communication of content • Tools and authoring applications • HTML 5, DreawWeaver, PhotoShop etc • Security / Ethical Considerations • Sony pictures leak • Pirate Bay • Genesis & Icefilms

  9. History of Multimedia • Newspapers – text & graphics • Rome 59B.C. China 202 B.C • Venice 16C • Johann Gutenberg : the printing press 1450's • Motion pictures - 19th & 20th Century – The Jazz Singer 1927 (The first feature-length Hollywood "talkie") • Radio - Marconi 1895 • Television / Video 20th C 

  10. Multimedia Landmarks • 1945 MEMEX Vannevar Bush described a theoretical machine able to display books and films with the ability to follow cross-references from one article to another • 1960s Xanadu – Ted Nelson – Hypertext • 1968 Douglas Engelbart – On Line System NLS (Outline Editor, Hypertext Links, Teleconferencing, Word Processing, E Mail, Mouse Pointing Device, Windowing Software and Help Systems.) • 1989 Tim Berners-Lee The World Wide Web

  11. Hypermedia and Multimedia • Ted Nelson – Hypertext • Book – linear • Hypertext – non linear • Hypermedia • Not just text based • Electronic newspapers • Reference tools • Games • Home shopping • On-line study • Video / Film on demand A user interface should be so simple that a beginner in an emergency can understand it within ten seconds. Ted Nelson.

  12. The World Wide Web • Up until about 1989 the Internet existed quite happily without the World Wide Web • File Transfer Protocol (FTP) • Telnet • Usenet • World Wide Web is not the Internet!

  13. Hyper Text Transfer Protocol (HTTP) • A protocol is an agreed set of rules for doing something • HTTP designed for transmitting hypermedia • The Uniform Resource Locator identifies the resource accessed For example the URL: • http://www.cse.dmu.ac.uk/~mjdean/time.shtml

  14. Some Processes in HTTP Client side scripting

  15. Problems and Limitations Associated with HTML • There are two issues associated with HTML which need to be considered • Standardisation (or lack of) • "Browser Wars" • HTML is a mark-up language and is not very good at specifying presentation • Introduction of Cascading Style Sheets • The World Wide Web Consortium •  http://www.w3.org • "W3C primarily pursues its mission through the creation of Web standards and guidelines"

  16. HTML • Much tighter specification devised based on XML i.e. XHTML • XHTML - transitional • XHTML strict • Unfortunately the standards were not widely adopted • Some people went back to HTML 4 • Some stopped at XHTML transitional • Some browsers didn’t implement the support for XHTML •  2006 the W3C changed their mind and around 2007 pretty much abandoned XHTML in favor of HTML 5 • Follows many rules of XML but more relaxed • Includes native support for multimedia

  17. Multimedia Software Tools • Music Sequencing and Notation • Cakewalk • Cubase • Digital Audio • Adobe Audition (Was Cool Edit) • Sound Forge • Pro Tools • Graphics and Image Editing • Adobe Photoshop • Adobe Fireworks • Video Editing • Adobe Premier • Animation • Java script • Adobe Flash Thomas and John Knoll developers of PhotoShop John worked in a small experimental division of Industrial Light and Magic (George Lucas’s film studio) called Pixar.

  18. About the Module • Adobe Software Dreamweaver, Photoshop (Flash) • Web technologies HTML 5 & Java script • Creative use of technology in a Business Internet context • Hopefully it will be both challenging and fun

  19. Teaching Learning & Assessment • Teaching 2 x labs – 1 x lecture • Learning Driven by you I simply push you in the right direction • Assessment ????????????????

  20. Learning Resources • Course web site • http://www.cse.dmu.ac.uk/~mjdean (CTEC2608) • Detailed notes in Word & PowerPoint

  21. Schedule and Assessment • Pre Christmas – general overview of multimedia technology • After Christmas – HTML 5 & Animation using JavaScript
