The 3G IP Multimedia Subsystem (IMS): Merging the Internet and the Cellular Worlds, Second Edition is an updated version of the best-selling guide to this exciting technology that will merge the Internet with the cellular world, ensuring the availability of Internet technologies such as the web, email, instant messaging, presence and videoconferencing nearly everywhere. In this thoroughly revised overview of the IMS and its technologies, goals, history, vision, the organizations involved in its standardization and architecture, the authors first describe how each technology works on the Internet and then explain how the same technology is adapted to work in the IMS, enabling readers to take advantage of any current and future Internet service. Key features of the Second Edition include: New chapter on Next Generation Networks, including an overview on standardization, the architecture, and PSTN/ISDN simulation services. Fully updated chapter on the Push-to-talk over Cellular (PoC) service, covering the standardization in the Open Mobile Alliance (OMA), architecture, PoC session types, user plane, and the Talk Burst Control Protocol. Several expanded sections, including discussion of the role of the Open Mobile Alliance in the standardization process, IPv4 support in IMS, a description of the IMS Application Layer Gateway and the Transition Gateway, and a description of the presence data model. Updated material on the presence service, session-based instant messages with the Message Session Relay Protocol (MSRP), and the XML Configuration Access Protocol (XCAP). Supported by a companion website on which instructors and lecturers can find electronic versions of the figures. Engineers, programmers, business managers, marketing representatives, and technically aware users will all find this to be an indispensable guide to IMS and the business model behind it.

How to apply digital writing skills effectively in the classroom, from the prestigious National Writing Project As many teachers know, students may be adept at text messaging and communicating online but do not know how to craft a basic essay. In the classroom, students are increasingly required to create web-based or multi-media productions that also include writing. Since writing in and for the online realm often defies standard writing conventions, this book defines digital writing and examines how best to integrate new technologies into writing instruction. Shows how to integrate new technologies into classroom lessons Addresses the proliferation of writing in the digital age Offers a guide for improving students' online writing skills The book is an important manual for understanding this new frontier of writing for teachers, school leaders, university faculty, and teacher educators.

The advent of increasingly large consumer collections of audio (e.g., iTunes), imagery (e.g., Flickr), and video (e.g., YouTube) is driving a need not only for multimedia retrieval but also information extraction from and across media. Furthermore, industrial and government collections fuel requirements for stock media access, media preservation, broadcast news retrieval, identity management, and video surveillance. While significant advances have been made in language processing for information extraction from unstructured multilingual text and extraction of objects from imagery and video, these advances have been explored in largely independent research communities who have addressed extracting information from single media (e.g., text, imagery, audio). And yet users need to search for concepts across individual media, author multimedia artifacts, and perform multimedia analysis in many domains. This collection is intended to serve several purposes, including reporting the current state of the art, stimulating novel research, and encouraging cross-fertilization of distinct research disciplines. The collection and integration of a common base of intellectual material will provide an invaluable service from which to teach a future generation of cross disciplinary media scientists and engineers.

Explores and analyzes past and current technologies and trends in multimedia communication Digital natives—those persons born in the digital age—have an ever-widening range of wireless-enabled devices at their disposal. They are the drivers of multimedia communications, continually seeking out the technologies and distribution channels that best match their needs. This book outlines the changes in telecommunications that are occurring to meet these needs. It addresses the continually increasing requirement to provide connections that make the electronic encounter as natural and convenient as possible, exploring the vast assortment of devices that exist as part of everyday living for digital natives. Featuring precise diagrams and tables to illustrate the evolving environment, the book begins by describing the competitive interactions of telephone, cable TV, and cellular mobile companies in providing services and content. It outlines the creation of digital multimedia streams and how they are transported, explains what multimedia connections are available, and summarizes the activities of competitors while providing an overview of their markets and customer statistics. This book uniquely covers wireline, optical fiber, cable, and wireless access methods, explaining the coding required to create digital streams. It combines ethernet with provider bridging and multi-protocol label switching and highlights the necessity to serve legacy streams. In addition, the book addresses controversial issue: will incumbent communications providers ever overtake Internet as the chief source of digital feeds and popular contents? Featuring extensive references and a glossary of multimedia terms, Connections for the Digital Age is written for digital natives and other persons with an interest in multimedia communications; industrial, commercial, and financial managers; engineers; software professionals and Internet specialists; and students at technical schools and universities.

Provides a clear, coherent review of all major wireless broadband standards with an emphasis on managing the explosive growth in mobile video 802.11ac/ad, 802.16m, 802.22, and LTE-Advanced are the emerging broadband wireless standards that offer many powerful wireless features. This book gives an accessible overview of the various standards and practical information on 802.11 link adaptation, 4G smartphone antenna design, wireless video streaming, and smart grids. Broadband Wireless Multimedia Networks distills the many complex wireless features in a clean and concise manner so that the reader can understand the key principles. Topics covered include adaptive modulation and coding, orthogonal frequency-division multiple access, single-carrier frequency-division multiple access, multiple antenna systems, medium access control time and frequency-division duplex, transmission, and the frame formats. With wireless operators now carrying a much greater amount of video traffic than data and voice traffic, the book also covers adaptive bit rate streaming and bandwidth management for 3D and HD video delivery to multi-screen personal devices. Featured chapters in the book are: Overview of Broadband Wireless Networks IEEE 802.11 Standard IEEE 802.16 Standard Long-Term Evolution ATSC Digital TV and IEEE 802.22 Standards Mesh, Relay, and Interworking Networks Wireless Video Streaming Green Communications in Wireless Home Area Networks Including over 180 chapter-end exercises and 200 illustrative figures; and accessible recorded tutorials, Broadband Wireless Multimedia Networks is ideal for industry professionals and practitioners, graduate students, and researchers.

Third edition of this best-selling guide to IMS: fully revised, and updated with brand new material The IMS (IP Multimedia Subsystem) is the technology that merges the Internet with the cellular world. It makes Internet technologies such as the web, email, instant messaging, presence, and videoconferencing available nearly everywhere at any time. The third edition of this bestselling book is fully updated and provides comprehensively expanded content, including new chapters on emergency calls and on Voice Call Continuity (VCC).
