Intended Audience


This book describes audio/video transport over IP networks in considerable detail. It assumes some basic familiarity with IP network programming and the operation of network protocol stacks, and it builds on this knowledge to describe the features unique to audio/video transport. An extensive list of references is included, pointing readers to additional information on specific topics and to background reading material.

Several classes of readers might be expected to find this book useful:

  • Engineers . The primary audience is those building voice-over-IP applications, teleconferencing systems, and streaming media and webcasting applications. This book is a guide to the design and implementation of the media engine of such systems. It should be read in conjunction with the relevant technical standards, and it builds on those standards to show how a system is built. This book does not discuss signaling (for example, SIP, RTSP, or H.323), which is a separate subject worthy of a book in its own right. Instead it talks in detail about media transport, and how to achieve good-quality audio and smooth-motion video over IP networks.

  • Students . The book can be read as an accompaniment to a course in network protocol design or telecommunications, at either a graduate or an advanced undergraduate level. Familiarity with IP networks and layered protocol architectures is assumed. The unique aspects of protocols for real-time audio/video transport are highlighted, as are the differences from a typical layered system model. The cross-disciplinary nature of the subject is highlighted, in particular the relation between the psychology of human perception and the demands of robust media delivery.

  • Researchers . Academics and industrial researchers can use this book as a source of information about the standards and algorithms that constitute the current state of the art in real-time audio/video transport over IP networks. Pointers to the literature are included in the References section, and they will be useful starting points for those seeking further depth and areas where more research is needed.

  • Network administrators . An understanding of the technical protocols underpinning the common streaming audio/video applications is useful for those administering computer networks ”to show how those applications can affect the behavior of the network, and how the network can be engineered to suit those applications better. This book includes extensive discussion of the most common network behavior (and how applications can adapt to it), the needs of congestion control, and the security implications of real-time audio/video traffic.

In summary, this book can be used as a reference, in conjunction with the technical standards, as a study guide, or as part of an advanced course on network protocol design or communication technology.
