Chapter 2: Basics Chapter 3: Multimedia Systems Communication Aspects and Services Chapter 4: Multimedia Systems Storage Aspects Chapter 5: Multimedia Usage and Applications Documents and Hypermedia Multimedia User Interfaces Abstractions for Programming Multimedia Applications 5.4: Multimedia Applications Classifying Applications Example Conclusion Page 1
Classification of Applications Applications are of central significance: interact and create, modify and use of multimedia data No general approach for applications requirements differ with data Only possible: classification by series of transforms: Page 2
Media Preparation and Media Manipulation Media Preparation by media capture or data generation: Audio Video Text, Still and Motion Graphics 2D/3D Chapter 2 Change data by editing single medium: Text Pictures Graphics Animation Audio Video Tools: large variety media specific editors (Photoshop, GIMP, SoundTools...)

i-land CommChair Integrated computers or laptop docking Communication via WLAN User profiles... Components (HW + SW) Form dynamic offices Could be the basis of a future office Needs multimedia capabilities Page 9
Conclusion Lehrstuhl für Informatik 4 Multimedia Systems is not only about the media format also needs considerations how to store and access the media can be distributed: how to transmit the media over a network needs new user interfaces and programming concepts Multimedia in the future Distributed applications are becoming more important Need of portability and system independence Better support for user activity Variety of new (still undiscovered) application domains?
