- 2. 3 What is Multimedia? „ Multi- means many; much; multiple „ Medium means: „ An intervening substance through which something is transmitted or carried on „ A means of mass communication such as newspaper, magazine, or television „ Multimedia is the combinations of text, graphic art, sound, animation, video and other kinds of elements. „ When a viewer of a multimedia presentation is allowed to control what elements are delivered „ and when, it is interactive multimedia. „ Multimedia is an inter-disciplinary subject because it involves a variety of different theories „ and skills: „ these include computer technology, hardware and software; „ arts and design, literature, presentation skills; „ application domain knowledge. Overview of Multimedia Software Tools • The categories of software tools briefly examined here are: 1. Music Sequencing and Notation 2. Digital Audio 3. Graphics and Image Editing 4. Video Editing 5. Animation 6. Multimedia Authoring 4
- 3. 5 Multimedia Global Structure Application domain — provides functions to the user to develop and present multimedia projects. This includes Software tools, and multimedia projects development methodology. System domain — including all supports for using the functions of the device domain, e.g., operating systems, communication systems (networking) and database systems. Device domain — basic concepts and skill for processing various multimedia elements and for handling physical device. 6 Multimedia Global Structure Multimedia and Computer Science: – Graphics, HCI, visualization, computer vision, data compression, graph theory, networking, database systems. Multimedia and Hypermedia ‰ Multimedia involves multiple modalities of text, audio, images, drawings, animation, and video. ‰ Examples of how these modalities are put to use: • Video teleconferencing. • Distributed lectures for higher education. • Tele-medicine. • Co-operative work environments. TEXT AUDIO GRAPHIC VIDEO ANIMATION
- 4. What is a Multimedia System? „ A system that involves: „ generation „ representation „ storage „ transmission „ search and retrieval „ delivery of multimedia information ¾ production/authoring tools ¾ compression and formats ¾ file system design ¾ networking issues ¾ database management ¾ server design, streaming 7 8 Multimedia Computing „ Multimedia systems involve some basic enabling techniques: „ Multimedia data representation and compression. „ Multimedia data processing and analysis. „ Transmitting multimedia data through communication networks. „ Multimedia database, indexing and retrieval.
- 5. 9 Challenges of Multimedia Computing „ Developing a successful multimedia system is non-trivial. „ Continuous media types such as video need a lot of space to store and very high bandwidth to transmit. „ They also have tight timing constraints. „ Automatically analyzing, indexing and organizing information in audio, image and video is much harder than from text. „ Multimedia involves many different research areas and needs more complex and more efficient algorithms and hardware platforms. 10 Linear VS Non-Linear „ A Multimedia Project is identified as Linear when: „ It is not interactive „ User have no control over the content that is being showed to them. „ Example: „ A movie „ A non-interactive lecture / demo show LINEAR
- 6. 11 Linear VS Non-Linear „ A Multimedia Project is identified as Non-Linear when: „ It is interactive „ Users have control over the content that is being showed to them. „ Users are given navigational control „ Example: „ Games „ Courseware „ Interactive CD NON-LINEAR 12 Hypermedia and Multimedia • A hypertext system: meant to be read nonlinearly, by following links that point to other parts of the document, or to other documents (Fig. 1.1) • HyperMedia: not constrained to be text-based, can include other media, e.g., graphics, images, and especially the continuous media – sound and video. - The World Wide Web (WWW) — the best example of a hypermedia application. • Multimedia means that computer information can be represented through audio, graphics, images, video, and animation in addition to traditional media.
