- 7. Multimedia systems must be computer controlled . The information they handle must be represented digitally . The interface to the final presentation of media is usually interactive .
- 8. Supporting multimedia applications over a computer network renders the application distributed or applications executed in mobile devices . Data has to represented digitally so many initial source of data needs to be digitise -- translated from analog source to digital representation.
- 9. The data is large several Mb easily for audio and video -- therefore storage, transfer (bandwidth) and processing overheads are high. Data compression techniques very common
- 10. World Wide Web Video conferencing Video-on-demand Interactive TV Home shopping Games Virtual reality Digital video editing and production systems Multimedia Database systems
- 11. Digital Radio VoIP
- 12. Big Ben in Madrid

- 16. To create a multimedia application may be necessary: Image retouching Sound edition Create and edit digital video Create animations Also the main trends are multimedia web applications
- 17. We need to know compression mechanism to multimedia items We need to know web programming language to insert multimedia items and create our first simple multimedia application.
