Quality and Reliability of Telecommunications Infrastructure: Quality And Reliability Of Telecommunications Infrastructure (LEA Telecommunications Series)
by William LehrIn the last decade, the technology, regulation, and industry structure of our information infrastructure (telephone services, cable and broadcast television, and myriad new data and information services) have changed dramatically. Since the break-up of AT&T's Bell System monopoly, telephone services in the United States are no longer purchased from a single firm. Advances in fiber optics, wireless communications and software-controlled switching are changing how communication services are provided. As the global economy grows more dependent on a hybrid mix of interconnected networks, public officials in the US and abroad are relinquishing control of the market. All of these changes are affecting the quality and reliability of the telecommunications infrastructure, but informed discussions of the public policy and economic issues are scarce. Deregulation and increased competition have lowered prices, but have service quality and reliability suffered? Do advanced network technologies which make it possible to offer a dizzying array of new services increase vulnerability to system-wide failures? Who should or is likely to bear the costs of increased -- or decreased -- service quality? This volume tackles the economic and public policy issues raised by these difficult questions for an audience of industry executives, scholars, and policymakers. Leading scholars and analysts examine such issues as the effects of network ownership on incentives to invest in quality improvements and/or strategies for quality-differentiated pricing in tomorrow's broadband, integrated networks. They analyze the quality of current telecommunications networks and the impact of re-regulation on cable television quality. The contributions range from new microeconomic theory to new empirical research. As such, the volume makes a valuable contribution to the public debate on network quality and reliability. It will be useful both as an introduction to newcomers and as a resource for more experienced researchers. As regulatory, industry and national barriers to integrated communications fall, these issues are likely to become even more important. The research presented here provides a solid foundation for further discussion.

Quality of Experience Engineering for Customer Added Value Services: From Evaluation to Monitoring
by Abdelhamid Mellouk Antonio Cuadra-SanchezThe main objective of the book is to present state-of-the-art research results and experience reports in the area of quality monitoring for customer experience management, addressing topics which are currently important, such as service-aware future Internet architecture for Quality of Experience (QoE) management on multimedia applications. In recent years, multimedia applications and services have experienced a sudden growth. Today, video display is not limited to the traditional areas of movies and television on TV sets, but these applications are accessed in different environments, with different devices and under different conditions. In addition, the continuous emergence of new services, along with increasing competition, is forcing network operators and service providers to focus all their efforts on customer satisfaction, although determining the QoE is not a trivial task. This book addresses the QoE for improving customer perception when using added value services offered by service providers, from evaluation to monitoring and other management processes.
Quality of Experience for Multimedia: Application to Content Delivery Network Architecture
by Abdelhamid Mellouk Hai Anh Tran Said HoceiniBased on a convergence of network technologies, the Next Generation Network (NGN) is being deployed to carry high quality video and voice data. In fact, the convergence of network technologies has been driven by the converging needs of end-users.The perceived end-to-end quality is one of the main goals required by users that must be guaranteed by the network operators and the Internet Service Providers, through manufacturer equipment. This is referred to as the notion of Quality of Experience (QoE) and is becoming commonly used to represent user perception. The QoE is not a technical metric, but rather a concept consisting of all elements of a user's perception of the network services. The authors of this book focus on the idea of how to integrate the QoE into a control-command chain in order to construct an adaptive network system. More precisely, in the context of Content-Oriented Networks used to redesign the current Internet architecture to accommodate content-oriented applications and services, they aim to describe an end-to-end QoE model applied to a Content Distribution Network architecture. About the Authors Abdelhamid Mellouk is Full Professor at University of Paris-Est C-VdM (UPEC), Networks & Telecommunications (N&T) Department and LiSSi Laboratory, France.

Quality of Experience Modeling for Cloud Gaming Services (T-Labs Series in Telecommunication Services)
by Saman ZadtootaghajThis book presents the development of a gaming quality model to predict the gaming Quality of Experience (QoE) of players that could be used for planning the network service or quality monitoring of cloud gaming services. The author presents a model that is developed following a modular structure approach that keeps the different types of impairments separately. The book shows how such a modular structure allows developing a sustainable model as each component can be updated by advances in that specific research area or technology. The presented gaming quality model takes into account two modules of video quality and input quality. The latter considers the interactivity aspects of gaming. The video quality module offers a series of models that differ depending on the level of access to the video stream information, allowing high flexibility for service providers regarding the positions of measuring points within their system. In summary, the present book focuses on (1) creation of multiple image/video and cloud gaming quality datasets, (2) development of a gaming video classification, and (3) development of a series of gaming QoE models to predict the gaming QoE depending on the level of access to the video stream information.
Quality of Synthetic Speech
by Florian HinterleitnerThis book reviews research towards perceptual quality dimensions of synthetic speech, compares these findings with the state of the art, and derives a set of five universal perceptual quality dimensions for TTS signals. They are: (i) naturalness of voice, (ii) prosodic quality, (iii) fluency and intelligibility, (iv) absence of disturbances, and (v) calmness. Moreover, a test protocol for the efficient indentification of those dimensions in a listening test is introduced. Furthermore, several factors influencing these dimensions are examined. In addition, different techniques for the instrumental quality assessment of TTS signals are introduced, reviewed and tested. Finally, the requirements for the integration of an instrumental quality measure into a concatenative TTS system are examined.

Quantified: Biosensing Technologies in Everyday Life
by Dawn NafusWhat is at stake socially, culturally, politically, and economically when we routinely use technology to gather information about our bodies and environments? Today anyone can purchase technology that can track, quantify, and measure the body and its environment. Wearable or portable sensors detect heart rates, glucose levels, steps taken, water quality, genomes, and microbiomes, and turn them into electronic data. Is this phenomenon empowering, or a new form of social control? Who volunteers to enumerate bodily experiences, and who is forced to do so? Who interprets the resulting data? How does all this affect the relationship between medical practice and self care, between scientific and lay knowledge? Quantified examines these and other issues that arise when biosensing technologies become part of everyday life.The book offers a range of perspectives, with views from the social sciences, cultural studies, journalism, industry, and the nonprofit world. The contributors consider data, personhood, and the urge to self-quantify; legal, commercial, and medical issues, including privacy, the outsourcing of medical advice, and self-tracking as a “paraclinical” practice; and technical concerns, including interoperability, sociotechnical calibration, alternative views of data, and new space for design.ContributorsMarc Böhlen, Geoffrey C.
