Multimedia Multicast On The Internet

This book examines multicast technology and will be a key text for undergraduate engineering students and master students in networks and telecoms. However, it will be equally useful for a wide range of professionals in this research field. Multicast routing was introduced with the advent of multiparty applications (for example, videoconferencing on the Internet) and collaborative work (for example, distributed simulations). It is related to the concept of group communication, a technique introduced to reduce communication costs. The various problems of multicast routing on the Internet are examined in detail. They include: group membership management, quality of service, reliability, safety, scalability and transport. Throughout the text, several protocols are introduced in order to analyze, compare and cover the various aspects of multicast routing.

Your best source for powering up your network with IP multicast applications Videoconferencing, video broadcasting, collaborative applications, push technologies . . . these and other new-wave networking applications are changing the way business is done. And it's your job to make sure that your company's network is equipped to handle them. This comprehensive guide gets you quickly up to speed on all technical aspects of IP multicasting-the key to delivering high-performance multimedia applications. In IP Multicasting, author Dave Kosiur clearly describes the differences between unicasting and multicasting, how multicasting works, and how it can be used to deliver the new generation of business applications. He explains the protocols and systems associated with multicasting, tells you how to prepare your network for multicasting, and what to look for when buying and upgrading network infrastructure equipment and software to ensure optimal performance. He also arms you with: * Proven implementation strategies * Everything you need to know about routing for IP multicasting * All about RTP, RTCP, RTSP, and other transport protocols * Expert guidance on integrated network services and QoS * Critical reviews of the latest multicasting software and applications. IP Multicasting is your best source for the technical know-how you need to provide your users with the sophisticated networking capabilities they demand.

This book constitutes the refereed proceedings of the 5th IFIP/IEEE International Conference on the Management of Multimedia Networks and Services, MMNS 2002, held in Santa Barbara, CA, USA, in October 2002. The 27 revised full papers presented were carefully reviewed and selected from a total of 76 submissions. The papers are organized in topical sections on service management, management of wireless multimedia, bandwidth sharing protocols, distributed video architectures, management systems, differentiated network services, user level traffic adaptation, and multicast congestion control.

Introducing mobile multimedia – the technologies, digital rights management and everything else you need to know for delivering cost efficient multimedia to mobile terminals Efficiency and cost effectiveness within multimedia delivery is fast becoming a hot topic in wireless communications, with mobile operators competing to offer inexpensive, reliable services. The selection of an appropriate technology and matching it with the offered mix of services will be essential to achieve the market success. Multimedia Broadcasting and Multicasting in Mobile Networks discusses multimedia services, introducing the potentials and limitations of the multicasting and broadcasting technologies. The authors address the key points related to the deployment of the technology including digital rights management issues, particularly important in terms of the large, business scale deployment of multimedia services and business models. The book discusses the early trials and deployment of Internet Protocol Datacasting (IPDC) and Multimedia Broadcast/Multicast Service (MBMS) and offers an introduction to multicasting in wireless cellular networks. Multimedia Broadcasting and Multicasting in Mobile Networks: Offers a tutorial introduction to multicasting in wireless cellular networks Provides an overview of the current technologies that deliver mobile multimedia, weighing of the potentials and limitations of various solutions Includes the early trials and deployment of Internet Protocol Datacasting (IPDC) and Multimedia Broadcast/Multicast Service (MBMS) Details Digital Rights Management (DRM), MediaFLO, Digital Multimedia Broadcasting (DMB), Terrestrial Integrated Services Digital Broadcasting (ISDB-T) and others Contains business models, trials and user feedback This book provides mobile operators, graduate engineers, network designers and strategists in mobile engineering with a thorough understanding of mobile multimedia and its impact on the telecommunications industry. Undergraduate and postgraduate students studying telecommunications will also find this book of interest.

Here is a thorough, not-overly-complex introduction to the three technical foundations for multimedia applications across the Internet: communications (principles, technologies and networking); compressive encoding of digital media; and Internet protocol and services. All the contributing systems elements are explained through descriptive text and numerous illustrative figures; the result is a book well-suited toward non-specialists, preferably with technical background, who need well-composed tutorial introductions to the three foundation areas. The text discusses the latest advances in digital audio and video encoding, optical and wireless communications technologies, high-speed access networks, and IP-based media streaming, all crucial enablers of the multimedia Internet.

A tutorial and complete description of the core concepts and real-world applications of IP multicast, one of the most effective solutions alleviating network congestion. The author, one of the key technologists in multicasting, describes a series of multicast applications and shows how they can be used to improve business processes and information dispersal without causing network infrastructure overload.

This practical resource provides a survey on the technologies, protocols, and architectures that are widely used in practice to implement networked multimedia services. The book presents the background and basic concepts behind multimedia networking, and provides a detailed analysis of how multimedia services work, reviewing the diverse network protocols that are of common use to implement them. To guide the explanation of concepts, the book focuses on a representative set of networked multimedia services with proven success and high penetration in the telecommunication market, namely Internet telephony, Video-on-Demand (VoD), and live IP television (IPTV). Contents are presented following a stepwise approach, describing each network protocol in the context of a networked multimedia service and making appropriate references to the protocol as needed in the description of other multimedia services. This book also contains questions and exercises to provide the reader with insight on the practical application of the explained concepts. Additionally, a laboratory practice is included, based on open-source tools and software, to analyze the operation of an Internet telephony service from a practical perspective, as well as to deploy some of its fundamental components.
