T2 - European and Mediterranean Conference on Information Systems N2 - As the potential of a Next Generation Network (NGN) is recognized, telecommunication companies consider switching to it. Although the implementation of an NGN seems to be merely a modification of the network infrastructure, it may trigger or require changes in the whole company and even influence the company strategy. To capture the effects of NGN we propose a framework based on concepts of business engineering and technical recommendations for the introduction of NGN technology. The specific design of solutions for the layers "Strategy", "Processes" and "Information Systems" as well as their interdependencies are an essential characteristic of the developed framework. We have per-formed a case study on NGN implementation and observed that all layers captured by our framework are influenced by the introduction of an NGN.

ToF sensors provide full range distance information at high frame-rates and thus have a significant impact onto current research in areas like online object recognition, collision prevention or scene reconstruction. However, ToF cameras like the photonic mixer device (PMD) still exhibit a number of challenges regarding static and dynamic effects, e.g. systematic distance errors and motion artefacts, respectively. Sensor calibration techniques reducing static system errors have been proposed and show promising results. However, current calibration techniques in general need a large set of reference data in order to determine the corresponding parameters for the calibration model. This paper introduces a new calibration approach which combines different demodulation techniques for the ToF- camera 's reference signal. Examples show, that the resulting combined demodulation technique yields improved distance values based on only two required reference data sets.

To make use of this method, detailed information about the user and the place where the user interacts with his mobile device is required. This article describes how both can be modeled by a stereotypical and conceptual extended UML extension. Finally, a software tool is presented that supports the developed UML extension.

High Quality Streaming beschäftigt sich mit High Definition Television und Mehrkanal Sound. In diesem Beitrag werden die Technologien und Anwendungsperspektiven für HD Medien-Dienstleistungen beschrieben. Der Beitrag entstand im Rahmen der Konferenz Medienproduktion „Expansion und Mobilität“ am 7. Dezember 2007. Der Beitrag beschreibt Geschäftsmodelle, Technologien und neue Anwendungen für High Quality Streaming. Neben der Präsentation wurden auch die Medienproduktionen der unterschiedlichen HQ-Mediendienste vorgeführt. Die Mediendienste sind im Rahmen der Forschungsarbeit High Quality Media Services des Studiengangs Communication and Multimedia Design (Fachbereich Elektrotechnik und Informationstechnik) an der Fachhochschule Aachen entstanden. Eine Marktevaluierung der deutschen und niederländischen Märkte, internationale Expertengesprächen sowie ein Prototypen HDMediaservices bilden die Basis der Forschungsarbeit. Die Mediendienste stehen zur Demonstration unter dem Link media.fh-aachen.de bereit. HQ-Mediendienste bedeuten: Gestochen scharfe Bilder in High Definition, volle Klänge in Surround und das über das Internet, wo doch gerade mal die briefmarkengroßen Bilder mit unscharfen Konturen und krätzenden Klängen der heutigen Portale wie YouTube Alltag sind.
