  1. SWE 423: Multimedia Systems Chapter 1: Introduction

  2. What constitutes Multimedia • Multimedia involves several major industries • computing • telecommunications • publishing • consumer audio-video • electronics • television/movie/broadcasting

  3. Brief History of Multimedia Systems

  4. Electronic Numerical Integrator And Calculator (ENIAC) • Built at the University of Pennsylvania between 1943 and 1945 by two professors • On the premise of replacing all computers! • Women employed calculating the firing tables for the army's artillery guns • Filled a  6 by 12 meter room, weighed 30 tons! • A “Female Computer”: “I was astounded that it took all this equipment to multiply 5 by 1000”

  5. To perform on ENIAC you had to rearrange a large number of patch cords and then locate three particular knobs on that vast wall of knobs and set them to 3, 1, and 4 Circumference = 3.14 * diameter

  6. Multimedia is still at its infancy • Cannot avoid fuzziness in scope, multiplicity of definitions and non-stabilized terminology.

  7. MIT Media Lab in Boston • One of the first and best known institutes that studied multimedia • Innovative applications • Personalized newspapers • Life-sized holograms • Telephones that chat with callers • ...

  8. Great Impact of Multimedia • Integrating all media in the computer allows using the existing computer power to represent information interactively. • This can, also, be transmitted over computer networks.

  9. Interdisciplinary Aspects of Multimedia • Telecommunication industry • Consumer electronics industry • TV and radio broadcasting sector • “Publishing” industry
