Get a clear picture of IP Multicast applications for delivering commercial high-quality video services This book provides a concise guide to current IP Multicast technology and its applications, with a focus on IP-based Television (IPTV) and Digital Video Broadcast-Handheld (DVB-H) applications—areas of tremendous commercial interest. Traditional phone companies can use IP Multicast technology to deliver video services over their networks; cell phone companies can use it to stream video to handheld phones and PDAs; and many cable TV companies are considering upgrading to IP technology. In addition to applications in industries seeking to provide high-quality digital video and audio, there are numerous other practical uses: multi-site corporate videoconferencing; broad distribution of financial data, stock quotes, and news bulletins; database replication; software distribution; and content caching (for example, Web site caching). After an introduction that gets readers up to speed on the basics, IP Multicast with Applications to IPTV and Mobile DVB-H: Discusses multicast addressing for payload and payload forwarding Covers routing in a variety of protocols, including PIM-SM, CBT, PIM-DM, DVMRP, and MOSPF Discusses multicasting in IPv6 environments and Multicast Listener Discovery (MLD) Features examples of IP Multicast applications in the IPTV and mobile DVB-H environments Includes reference RFCs and protocols placed in the proper context of a commercial-grade infrastructure for the delivery of robust, entertainment-quality linear and nonlinear video programming This is a concise, compact reference for practitioners who seek a quick, practical review of the topic with an emphasis on the major and most often used aspects of the technology. It serves as a hands-on resource for engineers in the communications industry or Internet design, content providers, and researchers. It's also an excellent text for college courses on IP Multicast and/or IPTV.
Communication Technology Update, Third Edition provides the latest information on as many communication technologies as possible, using as many specific statistics on market share, units sold, etc., as possible to allow comparison among the technologies. This book is designed to help make sense of the spectrum of communication technologies. The text explores the widest possible range of technologies, from broadcast to telephony and from wired to wireless. In discussing each technology, this book will not only deal with the hardware of the technology, but also with the software, organizational structure, political and economic influences, and individual users of the technologies. Major developments in each of these areas are presented for each technology, along with background information to help explain the major factors in the evolution of the technology. The first chapter begins by defining communication technology and introducing the ""umbrella perspective"" used to present and analyze each technology. Following this discussion, an overview of the remainder of the book is presented. This book targets two groups of users. One of which is the group of communication professionals who have a desire to keep up with the latest developments both within and adjacent to their particular fields. Second is the group of students who are studying communication technology and need information that is more current than that provided by a textbook and more comprehensive than that found in trade magazines.
