What will the future of wireless communications look like? What drives mobile communications systems beyond 3G? In Next Generation Mobile Systems the authors answer these questions and others surrounding the new technologies. The book examines the current research issues driving the wireless world and provides an inclusive overview of how established technologies will evolve to suit next generation mobile systems. While the term '4G' already dominates research in industry and academia, there are still numerous hurdles to take before this ambitious concept can become reality. Acclaimed researchers from NTT-DoCoMo take up the debate of what type of mobile communications will emerge in the post-3G era. Next Generation Mobile Systems: Covers the evolution of IP-based systems and IP mobility. Gives a detailed overview of radio-access technologies and wireless LANs. Explains APIs for mobile systems and IP mobility. Addresses middleware and applications, including terminal platform technologies, multimedia, and wireless web services. Discusses security in future mobile networks, including sections on Cryptographic Algorithms and Protocols for XG, Authentication, Authorization, and Accounting, and Security Policy Enforcement for Downloaded Code. This valuable resource will provide communications engineers, telecommunications managers and researchers in industry and academia with a sound understanding of the future direction of mobile technology. We are currently in a digital content era. With the increase in circulation of multimedia content globally via the internet it has lead to the need for reuse of content stored in archives; the utilisation of newly stored materials; partially finished broadcasting programmes and finished content. This book proposes to show solutions to these numerous content issues. It will discuss large scale archives for significant content and a retrieval method for large scale archives and remote editing. The book will also examine the protection of intellectual property rights, which is one of the most important issues facing content owners. Examines the design and implementation of a practical digital content production system Proposes to show solutions to various content issues Covers various retrieval methods for large-scale archives using MPEG-1 streaming technology and remote editing using an original time code Discusses large-scale video archive systems which will enable high speed retrieval and edit functions for large amounts of video data with multi-purpose applications A resource that all broadcast engineers, systems integrators and engineers for equipment manufacturers will find invaluable. The thorough approach to this topic ensures that this title will become the standard reference for R&D specialists in content production and digital archiving.
