This important volume reviews the history of the telecommunication superhighway pointing out its beginnings in the interactive TV and broadband highway of the wired cities more than two decades ago. It explains the technological uncertainties of the superhighway and many of its futuristic services, and also gives an understandable review of the technological principles behind today's modern telecommunication networks and systems.
Recognizing that technology is only one factor in shaping the future, the author, a well-recognized telecommunications expert, analyzes the financial, policy,...

The revolution of wireless communications has only just begun to transform the telecommunications industry worldwide. This book offers insight into the possible options for corporate strategists and government policymakers as they look to harness the expansion of wireless communications to meet the goals of sustainable telecommunications development. Using a multidisciplinary approach which combines policy research, legal analysis, business economics, and models of sustainability from the environmental sciences, the book compares the development of wireless communications in four countries:...

An examination of the state of journalism and the need for change. For students and professionals on journalism fields.

Commemorating the 25th anniversary of the Telecommunications Policy Research Conference (TPRC), this volume begins with a historical survey of a quarter-century of TPRC meetings as one measure of change in and research about the telecommunications industry. Additional papers reflecting the ongoing pace of change in technological, economic, and policy issues are organized around four topics:
* economic analysis of local and international telephone policy;
* media industry studies including video competition, guidelines for children's educational television, and the setting of AM...

Over the past 40 years, satellites have played a key role in creating a global culture, spreading worldwide entertainment, stimulating technological interchange, and promoting trade around the world. Communications Satellites: Global Change Agents addresses communications satellites not only in terms of the technology and the services they provide, but also with consideration of the technology's impact in socio-political, security, economic, policy, news, entertainment, and cultural spheres.
Editors Joseph N. Pelton, Robert J. Oslund, and Peter Marshall bring together contributions...

In 1993, the author set out to try and gain some understanding about school and community in Havens, New Mexico--a place where she had the opportunity to be immersed in border culture, where she could learn how the border figured into everyday life, and where she could pay uninterrupted attention to the issues as they occurred in the personal and professional lives of those who taught in and administered the schools--and in the lives of the students who studied there. This book offers an interpretation that is disciplined by the long hours, days, and months spent in Havens, and by the...

This book discusses the growth of digital television technology and the revolution in image and video compression (such as JPEG2000, broadcast TV, video phone), highlighting the need for standardisation in processing static and moving images and their exchange between computer systems. The book gives an authoritative explanation of picture and video coding algorithms, working from basic principles through to the advanced video compression systems now being developed. One of its main objectives is to describe the reasons behind the introduction of a standard codec for a specific application...

This book gives a self-contained introduction to the subject of asymptotic approximation for multivariate integrals for both mathematicians and applied scientists. A collection of results of the Laplace methods is given. Such methods are useful for example in reliability, statistics, theoretical physics and information theory. An important special case is the approximation of multidimensional normal integrals. Here the relation between the differential geometry of the boundary of the integration domain and the asymptotic probability content is derived. One of the most important applications...

Das Gebiet der Telekommunikation befmdet sich derzeit in einer sttirmischen Entwick lungsphase. Nach vielen Dekaden relativ besUindiger Weiterentwicklung treten wir in einen Zeitabschnitt ein, in dem sich groBe Vedinderungen abzeichnen. Das gilt sowohl fUr die neuen technischen Verfahren zur Nachrichtentibermittlung als auch die damit moglich gewordenen neuen Formen ihrer Nutzung. Unter dem Wort Breitbandkommu nikation verstand man bis vor kurzem lediglich den Empfang von Horfunk-und Femseh programmen, und dies meist nur mittels einer auf dem Hausdach montierten Antenne. Immer mehr...
