Designed for computer scientists, electrical engineers and others interested in electronics, this work explains how a computer works via the fundamentals of quantum mechanics, multi-electron systems, crystal structure, semiconductor devices and logic circuits. The only prerequisite is some knowledge of calculus, and the second half of the book can stand alone as an introduction to the physics of electronics.

The liberalisation in the telecommunication market and thus the advent of competition has had a tremendous impact on business in this area. New operators have started to offer telecommunication services in competition with the classical national network operators. This in turn will have an impact on the market share, the tariff structure, the Quality of Service (QoS) and the services offered to the end customers. A way to maintain or increase revenue for network operators is to additionally offer new services to the customers. The final target is a so-called "e;Full Service Network (FSN)"e;, which is capable of offering all types of bi-directional multimedia services. The provisioning of new telecommunication services in general and new multimedia services in particular is made possible by the availability of several new technologies as well as through advances in standardisation. R&D policies world-wide but especially in Europe have forced the development of new networking technologies such as ATM, xDSL and HFC as well as new video technologies as defined by DVB and DAVIC.

The purpose of VLBV 2003 was to provide an international forum for the d- cussion of the state of the art of visual content processing techniques, standards, and applications covering areas such as: video/image analysis, representation and coding, communications and delivery, consumption, synthesis, protection, and adaptation. The topics of special interest include all the areas relevant to image communications nowadays, from representation and coding to content classi?cation, adaptation, and personalization. A meeting covering such a wide range of topics takes many years to develop. So, please follow a brief story of the evolution of this relevant and specialized forum and of its adaptation to the prevailing interests along time. At the beginning of 1993, the idea of a specialized workshop to discuss topics in advanced image communications came in Lausanne, Switzerland, at a m- ting of the steering committee of the International Picture Coding Symposium. Therefore, the so-called International Workshop on Coding Techniques for Very Low Bit-rate Video VLBV was born as low bit-rate research was considered to be the leading edge. The ?rst workshop was held at the University of Illinois at Urbana-Champaign, USA, in 1993; the second at the University of Essex in Colchester, UK, in April 1994; the third at NTT in Tokyo, Japan, in November 1995;thefourthattheUniversityofLink* oping,Sweden,inJuly1997;the?fthin Urbana (again) in October 1998. Until this last workshop, VLBV life was closely tied with MPEG-4, that is to low bit-rate research.

Not only computer scientists, but also electrical engineers, and others interested in electronics are targeted here, and thus the presentation is directed toward understanding how a computer works, while still providing a broad and effective one-year introduction to classical and modern physics.
