Book Description
Multimedia and Communications Technology is a practical explanation of the technologies that bring together existing products such as the PC, telephone and television. It is precisely this revolution that the book addresses - offering an up to date technical overview of developments in PC technology, video and audio compression, telecommunications and many other disciplines. Written as a series of tutorials, the book starts with the fundamental techniques of digital audio and video, moving on to compression techniques such as JPEG and MPEG. The delivery systems for multimedia are then covered, starting with the CD and on to telephones, local and wide area networks and ATM and ASDL. The final chapters describe how these technologies are brought together in some key applications: · video conferencing · digital video broadcasting · video on demand · interactive television Steve Heath is responsible for European Strategy and Technology Development at Motorola. He has had many years experience in computer design and has presented papers on multimedia technology at international conferences. He is a well known technical writer and has written fourteen other books for Focal Press, Newnes and Butterworth-Heinemann.

Book Description
The industrial nations of the world have become Information Societies. Advanced technologies have created a communication revolution, and the individual, through the advent of computers, has become an active participant in this process. The "human" aspect, therefore, is as important as technologically advanced media systems in understanding communication technology. The flagship book in the Series in Communication Technology & Society, Communication Technology introduces the history and uses of the new technologies and examines basic issues posed by interactive media in areas that affect intellectual, organization, and social life. Author and series co-editor Everett M. Rogers defines the field of communication technology with its major implications for researchers, students, and practitioners in an age of ever more advanced information exchange.

Book Description
This book is a comprehensive guide to understanding the design of wireless multimedia communications systems. Covering mobile video, voice, and data communications, it provides both professionals and students with an introduction to the problems and solutions of communicating multimedia traffic at high data rates over a radio channel for short distances. Wireless Multimedia Communications begins with an examination of the physical layer of the Open Systems Interface (OSI) stack, modeling the radio channel impairments, including path loss and multipath distortion. The book addresses infrared and satellite wireless channels and the digital modulation approaches used to convey information over these channels. It compares possible approaches to transmitting multimedia traffic, including equalization, multicarrier modulation, and spread spectrum. The book also presents an in-depth discussion of error control, with a look at the emerging and promising field of turbo coding. At the data link layer, the book presents an evaluation of Medium Access Control (MAC) protocols-such as Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Code Division Multiple Access (

Book Description
Drawing on a wide range of social and psychological theories, Castells presents original research on political processes and social movements. He applies this analysis to numerous recent events - the misinformation of the American public on the Iraq War,the global environmental movement to preventclimate change, the control of information in China and Russia, Barak Obama's internet-based presidential campaigns, and (in this new edition) responses to recent political and economic crises such as the Arab Spring and the Occupy movement. On the basis of these case studies he proposes a newtheory of power in the information age based on the management of communication networks.

Book Description
"This book is like a good tour guide.It doesn't just describe the major attractions; you share in the history, spirit, language, and culture of the place." --Henning Schulzrinne, Professor, Columbia University Since its birth in 1996, Session Initiation Protocol (SIP) has grown up. As a richer, much more robust technology, SIP today is fully capable of supporting the communication systems that power our twenty-first century work and life. This second edition handbook has been revamped to cover the newest standards, services, and products. You'll find the latest on SIP usage beyond VoIP, including Presence, instant messaging (IM), mobility, and emergency services, as well as peer-to-peer SIP applications, quality-of-service, and security issues--everything you need to build and deploy today's SIP services. This book will help you * Work with SIP in Presence and event-based communications * Handle SIP-based application-level mobility issues * Develop applications to facilitate communications access for users with disabilities * Set up Internet-based emergency services * Explore how peer-to-peer SIP systems may change VoIP * Understand the critical importance of Internet transparency * Identify relevant standards and specifications * Handle potential quality-of-service and security problems

Book Description
For almost forty years, DeeDee Halleck has been involved in a variety of projects that involve media making by "non-professionals." Her goal has been to develop a critical sense of the potential and limitations of mediated communication through practical exercises that generate a sense of both individual and non-hierarchical group power over the various apparati of media and electronic technology. Hand-Held Visions is a collection of essays, presentations, and lectures that she has written throughout this process. Halleck starts with a discussion of her own development as a teacher, producer, and an active participant in the struggle for media democracy. She gives the reader a historical first-person perspective on the community-based media movement and a sense of the determination and resolve that have enabled often fragile and much embattled organizations and individuals to survive in a climate dominated by global media corporations that are in direct opposition to their work.

Book Description
`This is a very clear and concise summary of media studies, present and future. There is no other book that can both be used as a teaching tool and can help scholars organize their thinking about new media as this book can' - Steve Jones, University of Chicago This book offers an introduction to communication theory that is appropriate to our post-broadcast, interactive, media environment. The author contrasts the `first media age' of broadcast with the `second media age' of interactivity. Communication Theory argues that the different kinds of communication dynamics found in cyberspace demand a reassessment of the methodologies used to explore media, as well as new understandings of the concepts of interaction and community (virtual communities and broadcast communities). The media are examined not simply in terms of content, but also in terms of medium and network forms. Holmes also explores the differences between analogue and digital cultures, and between cyberspace and virtual reality. The book serves both as an upper level textbook for New Media courses and a good general guide to understanding the sociological complexities of the modern communications environment.
