The Real-time Transport Protocol (RTP) provides a framework for delivery of audio and video across IP networks with unprecedented quality and reliability. In RTP: Audio and Video for the Internet, Colin Perkins, a leader of the RTP standardization process in the IETF, offers readers detailed technical guidance for designing, implementing, and managing any RTP-based system. By bringing together crucial information that was previously scattered or difficult to find, Perkins has created an incredible resource that enables professionals to leverage RTP's benefits in a wide range of Voice-over IP (VoIP) and streaming media applications. He demonstrates how RTP supports audio/video transmission in IP networks, and shares strategies for maximizing performance, robustness, security, and privacy. Comprehensive, exceptionally clear, and replete with examples, this book is the definitive RTP reference for every audio/video application designer, developer, researcher, and administrator. Key coverage includes: *RTP's goals, design philosophy, and relationships with other protocols *The psychology of human perception in the design of media delivery systems *RTP data transfer and control protocols, including framing, loss detection, reception quality feedback, and membership control *Media playout, timing, and synchronization, including lip synchronization *Mitigating network problems: error concealment, error correction, and congestion control *Optimizing performance over low-speed links: header compression, multiplexing, and tunneling *Integrating leading media codecs and standards into RTP systems *Securing RTP sessions: encryption, authentication, and the new secure RTP profile for wireless networks *Extensive references and practical examples throughout 0672322498B05092003

C'est un trés bon ouvrage sur le sujet. Il fournit de bonnes pistes concernant la gestion des buffers de reception et la synchro des medias. Rien que pour cela le livre est incontournable.

Perkins offers us a deep explanation of how RTP can handle real time audio and, more importantly, video across a standard Internet connection. RTP has now been around for some 10 years, and has been extensively built out, based on practical feedback from its earlier usages.
As you might expect, much of the text concerns the packet formats used in RTP. There are subsidiary protocols within RTP, like its control protocol. Naturally, these are explained, as they are a necessary part of the overall RTP.
Some chapters delve into specific timing issues. One, called lip synchronisation, refers to the difficulty of synchronising the audio and video portions of a video signal. Other chapters discuss how to conceal lost video packets. Error concealment is a very practical necessity in this field.

Colin Perkins is obviously well regarded in the area of RTP with many papers and research to his credit. This book is a very thorough and readable text on RTP. All aspects of RTP are covered in sufficient depth. The only thing that would have improved it would have been access to code. At various sections in the book he refers to an RTP stack that he has written. If this were made available as part of the book it would have been a killer combination. If I lost this book, I'd buy another one!
