1. Introduction to Multimedia

2. The beginning ( History )… 1945 : “…a device in which one stores all his books, records and communications, and which is mechanized so that it can be consulted with exceeding speed and flexibility. It is an enlarged intimate supplement to his memory.”

3. Con’t... 1969 - Early Hypertext and Collaborative research 1969 - Early Hypertext and Collaborative research Hypertext - the linking of associated data for easy access Hypermedia- the linking of any form of media

4. Con’t... Interactive multiperson editing, branching to different files, text search facilities, and outline processing Hypertext editing system on an IBM 360 Research continued by a 4th gen system, Intermedia, includes animation and video tools

5. Con’t... 1976 - AMG - Spatial Data Management –user would access a data item by traveling to it in a virtual space instead of referencing. 1971 - E-mail

6. Con’t 1980-1983 - Dave Backer - Electronic Book New system combining features of print, broadcast, and computer media. - Book like interface. - Touch screen interface. - annotations could be added - integrated sound, data, images, and video

7. Con’t 1985 - Negroponte & Jerome Wiesner - MIT Media Lab (circa 1985) - 11 research groups (EP, Film&Video, Visual Language, Elec.Music, Imaging and Photography, Learning, Movies of the future, Advanced TV Research, Speech Processing, HCI)

8. Con’t... Olivetti Research Lab - Cambridge, England – Active Badge - dynamic locator system. Made use of sensors in a building to track the badges being carried by people. 1990 - 1992 Apple Computer Multimedia Lab - Kristina Hooper Woosley - Multimedia in education - Visual Almanac (Directory)

9. Con’t… 1989 - Tim Bernes-Lee - proposed WWW European Council for Nuclear Research 1994 - Jim Clark & Marc Andersen - Netscape 1995 - First Java Applet - “Duke” 1996 - Microsoft Internet Explorer

10. Definition of Multimedia

11. Etymology Multi - (Latin) “multus” - numerous or many Media - (Latin) “medium” - middle or center. More recently intermediary Multimedia - “multiple intermediaries” or “multiple means”

12. Multimedia is... “The use of computers to present text, graphics, video, animation and sound in an integrated way.” “Multiple means by which information is stored, transmitted, presented, and perceived”

13. Interactive Multimedia is... “Seamless digital integration of text, graphics, animation, audio, still images and motion video in a way that provides individual users with high levels of control and interaction.”

14. Characteristics of Multimedia Must be computer controlled Must be integrated Information must be presented digitally The interface to the user may or may not permit interactivity

15. Categories of Multimedia Systems Stand-alone Multimedia Individual computer-based training CD-ROM Individual computer-based education Personal Computers

16. Categories of Multimedia Systems Networked Multimedia Networked Multimedia Genuinely networked multimedia - videoconferencing, multimedia electronic mail Client-server applications - pooling of resources such as a video disk unit

17. Benefits of Multimedia Easy to understand and use integrated and interactive conducive to cooperative work environment flexible supportive of a large audience

18. Challenges of Multimedia Computing power Data storage and management human interface usability network latency and throughput

19. Hardware and Software Considerations

20. Computing Capabilities Chart

21. Important Considerations Multimedia require huge amounts of storage during both the development and application stages. The large amount of data that needs to be transmitted requires a large bandwidth. Multimedia requires a fast processor speed due to the large amount of data required for sound and video. Multimedia requires a high display depth.

22. Progression of Technology 1975 - first personal computers were marketed - low processing power - black and green text-only screens - accounting and inventory

23. Progression Con’t... 1980 - addition of hard disk storage and simple graphics - forecasting and statistics 1987 - capability to display color - more advanced graphics, sound and animation

24. Progression Con’t... 1995 - capability to integrate digital video, sound, animation and text into one package - increased emphasis on communication capabilities & sharing of information - simulations, Internet, presentations

25. Hardware Requirements Depends on what type of multimedia products you wish to produce

26. Software Adobe Photoshop - Graphic manipulation; industry standard image processing tool Adobe Premiere - Digitized Video Manipulation Macromedia Flash- Create Vector- based interactive animations for web delivery. Designed for low bandwidth internet delivery
