WebRTC: APIs and RTCWEB Protocols of the HTML5 Real-Time Web [Englisch] [Taschenbuch]

Alan B. Johnston , Daniel C. Burnett

Erhältlich bei diesen Anbietern.


19. Juni 2013
IMPORTANT NOTE: The third edition of this book is now available! ISBN-13: 978-0-9859788-6-0 Up to date with the latest changes in the APIs and protocols, the third edition includes a new chapter on data channels with running demo code. A new step-by-step approach introduces developers to WebRTC starting with getting access to media, establishing a signaling connection, then creating the peer connection.

WebRTC, Web Real-Time Communications, is revolutionizing the way web users communicate, both in the consumer and enterprise worlds. WebRTC adds standard APIs (Application Programming Interfaces) and built-in real-time audio and video capabilities and codecs to browsers without a plug-in. With just a few lines of JavaScript, web developers can add high quality peer-to-peer voice, video, and data channel communications to their collaboration, conferencing, telephony, or even gaming site or application. Written by experts involved in the standardization effort, this book introduces and explains the W3C APIs and the IETF protocols of WebRTC. Packed with figures, example code, and summary tables, this book makes complicated concepts and technologies such as peer-to-peer media and NAT and firewall traversal easy to understand. The 2nd edition has all new chapters on Signaling and Security & Privacy, as well as running demo code (client and server-side) and further details on NAT traversal with ICE, STUN, and TURN protocols. In addition the book contains the latest updates on the W3C and IETF standards documents.

5.0 von 5 Sternen The best reference on WebRTC 6. September 2013
Von J. A. Quayle - Veröffentlicht auf
Alan Johnston and Dan Burnett have updated their excellent "The WebRTC book", the full title is "WebRTC: APIs and RTCWEB Protocols of the HTML5 Real-Time Web." It was only back in September 2012 I reviewed the first version of their excellent book, and much has happened, which is all captures in this second edition.

This edition begins with an introduction to WebRTC and discusses what is new about it. The unique aspects of WebRTC peer-to-peer media flows are explored, and Network Address Translation (NAT) traversal are explained. They have lots of new material, including new chapters on signaling, and privacy and security. They discuss the working documents and finalized documents that together comprise the WebRTC standards-in-progress in both the World Wide Web Consortium (W3C) and the Internet Engineering Task Force (IETF). And finally discuss the current state of deployment in popular browsers, which surprisingly hasn't changed that much over the past year compared to the standard.

Whether you're a developer looking to understand what WebRTC can do for you, or a marketing person wishing to gain a deeper understanding of an important industry development, or a strategy person digging deeper into what WebRTC is and isn't, this is the book for you. Easily accessible and frankly presented with no hyperbole just the facts, the book continues to provides the best review of a standard that will in time transform the web by making real-time communications an intrinsic part of the experience. The WebRTC Book remains one of my few "constant companion books" as its on my Kindle and on my desk.

5.0 von 5 Sternen Superb Intro & Detail on WebRTC 31. Juli 2013
Von T. Beck - Veröffentlicht auf
Format:Taschenbuch|Verifizierter Kauf
Need to get up to speed on WebRTC fast, this is the way forward: detailed, concise and well structured it gets you into the realm of browser Real Time Communications quickly but with a solid reference to the defining standards, some of which are still in motion.

A critical decision factor for me was the very recent Publication Date of this title, important for newer and evolving standards.

3.0 von 5 Sternen Covers a lot of theory. A good book, but not for getting up to speed quickly 21. August 2013
Von Mark Mandel - Veröffentlicht auf
Format:Kindle Edition|Verifizierter Kauf
My review is more of a word of warning.

If you are looking for a book that is very practical, with a lot of example code, and a lot of "here are a lot of small exercises to build you up to the more complicated things" - then this not the book for you.

While incredibly informative, this book is very, very, very heavy on the theory before it even gets into a sample application (which you can't download the code to, which is a point of frustration).

That being said, it is incredibly thorough, and attempts to explain almost every aspect of how a WebRTC system does (and could) work - which has value in it's own right.

All in all - I don't think you can get this information condensed into one package anywhere else, and they have done a very good job in attempting to put it all together, especially knowing the state of flux of WebRTC at the time of publishing.

5.0 von 5 Sternen A clear explanation of the merging of communications into the Web 16. Juli 2013
Von H. Sinnreich - Veröffentlicht auf
Format:Kindle Edition
Where new technologies mature and then quickly expand to global reach, Internet and Web standards are not far behind. This is exactly the present state of the emerging Web based Real-Time Communications also named for short WebRTC in the respective Internet and Web standards organizations, the IETF and W3C. This book provides clear explanations of the magic of combining in a secure manner countless Web applications with voice, video, texting, screen sharing and many others using only the browser, while enabling also connectivity to various other communication services. And all this is enabled by using global open standards and free software - at least such as from the authors' web page and numerous other sources.
The 2nd edition of the book "WebRTC: APIs and RTCWEB Protocols of the HTML5 Real-Time Web" by Alan Johnston and Dan Burnett in Kindle and print format has become available exactly at the right time for application developers, engineers, IT managers and analysts to get authoritative information from two authors who have not only credible background in both the communications and Web industries but are also active participants in the present standards development. For example, the subdued humor about the video codec and patents wars reveal the insider perspective. Being written by university educators and hands-on implementers also makes the book very easily readable.
Last but not least the associated web site and application code for testing WebRTC communications generates the excitement of following a live development, as has been the case with almost all new technologies and standards.
There is so much more one would like to share when reading this book, but I will stop here and just encourage everybody interested in these topics to start enjoying the book right away.

4.0 von 5 Sternen Gain good in-depth understanding about how real time communication will be in future 29. Dezember 2013

This book covers so much ground about WebRTC, which I could not have easily found elsewhere.
I would recommend this to anyone who is serious about building real time apps for future.
