Internet Protocol Television (IPTV) is rapidly being deployed as a compliment service to existing distribution technologies.

Why IPTV? traces the changes in Internet Protocol Television since the mid-1990s and examines what IPTV means today. The author analyzes what delivery of TV over an IP network means, both in terms of possibilities for new services, and in terms of the impact on the network and how it has to be managed. In addition, Why IPTV? helps you understand how introducing IPTV into the Web 2.0 world will impact the new services. It looks at the current trends in the consumer electronics industry as well as the network industry, and describes how the new technology can enhance and extend the existing business models in the TV industry, particularly in advertising; and also how it creates new possibilities, for instance, through personalization.

Why IPTV? Interactivity, Technologies, Services:

Why IPTV? will provide engineers in networking, TV broadcast companies, technology specialists in content creation companies and people in the IPTV industry (including management) with an engaging and insightful reference into Internet Protocol Television.

Local Positioning Systems: LBS Applications and Services explores the possible approaches and technologies to location problems including people and asset tracking, mobile resource management, public safety, and handset location-based services. The book examines several indoor positioning systems, providing detailed case studies of existing applications and their requirements, and shows how to set them up. Other chapters are dedicated to position computation algorithms using different signal metrics and determination methods, 2D/3D indoor map data and location models, indoor navigation, system components and how they work, privacy, deployment issues, and standards. In detail, the book explains the steps for deploying a location-enabled network, including doing a site-survey, creating a positioning model and floor maps, and access point placement and configuration. Also presented is a classification for network-based and ad-hoc positioning systems, and a framework for developing indoor LBS services.

This comprehensive guide will be invaluable to students and lecturers in the area of wireless computing. It will also be an enabling resource to developers and researchers seeking to expand their knowledge in this field.
