9 Media Advantage: Expressiveness Man-machine communication: From computer-oriented interfaces to human-oriented interfaces From a human perspective, interfaces are still insufficient: Speaking is faster than writing. Listening is easier than reading. Showing is better than describing. Information spectrum: Any idea requires a certain amount of information to express it Each medium has limitations on the information it can convey When information is transported through inappropriate media, parts of it may get lost Extended bandwidth of perception: More complete media spectrum with audio and video More familiar look-and-feel of man-machine interfaces Copyright, 1998 Universität Kaiserslautern, Fachbereich Informatik, AG Copyright, 1999 Universität Kaiserslautern, Fachbereich Informatik, AG
10 A Network Advantage: Reachability Network evolution: Today: Disjoint telephone, data and TV distribution networks Advantage: Pervasiveness Disadvantage: One medium only Almost today: Services Digital Networks (ISDNs) Advantage: Already voice and data Disadvantage: Only voice and data Tomorrow: Broadband Networks (IBCNs) Chicken-and and-egg problem: Consumers will not connect to the network before good services are available Providers do not offer services if there is no market Copyright, 1998 Universität Kaiserslautern, Fachbereich Informatik, AG Copyright, 1999 Universität Kaiserslautern, Fachbereich Informatik, AG
11 A Computer Advantage: Individuality Interaction: TV uses broadcast (couch-potato mode): Users can select program, but nothing else Prevents applications outside a mass market Computer at the receiving side can influence: When to watch What to watch Advantages: Adjustable degree of interaction Single-consumer applications Personalization: Computer can filter and select information Personalized newspaper Copyright, 1998 Universität Kaiserslautern, Fachbereich Informatik, AG Copyright, 1999 Universität Kaiserslautern, Fachbereich Informatik, AG
12 Another Computer Advantage: Processing Computer processing functions can be used to: Select information Modify information Interpret information Media transformation: Generate movie from textual description Play music from a score Media understanding: Audio commands Video analysis Copyright, 1998 Universität Kaiserslautern, Fachbereich Informatik, AG Copyright, 1999 Universität Kaiserslautern, Fachbereich Informatik, AG
13 Advantages Summary Media Advantage: Expressiveness Man-machine communication Information spectrum Extended bandwidth of perception A Network Advantage: Reachability Network evolution Chicken-and-egg problem A Computer Advantage: Individuality Interaction Personalization Processing Copyright, 1998 Universität Kaiserslautern, Fachbereich Informatik, AG Copyright, 1999 Universität Kaiserslautern, Fachbereich Informatik, AG
14 3.1 Steps toward Integration Stages of evolution: towards integrated digital systems Traditional approaches Computer controls audio/video components Digital, but not integrated communication communication, but separate local AV components Digital systems with analog interfaces Digital systems with all digital interfaces Copyright, 1998 Universität Kaiserslautern, Fachbereich Informatik, AG Copyright, 1999 Universität Kaiserslautern, Fachbereich Informatik, AG
15 Stage I: Traditional Approach Separation of analog and digital data: Continuous vs. discrete media Analog vs. digital Telecommunications vs. computers Circuit Switching digital Copyright, 1998 Universität Kaiserslautern, Fachbereich Informatik, AG Copyright, 1999 Universität Kaiserslautern, Fachbereich Informatik, AG
