Introduction to Digital Audio Coding and Standards provides a detailed introduction to the methods, implementations, and official standards of state-of-the-art audio coding technology. In the book, the theory and implementation of each of the basic coder building blocks is addressed. The building blocks are then fit together into a full coder and the reader is shown how to judge the performance of such a coder. Finally, the authors discuss the features, choices, and performance of the main state-of-the-art coders defined in the ISO/IEC MPEG and HDTV standards and in commercial use today. The ultimate goal of this book is to present the reader with a solid enough understanding of the major issues in the theory and implementation of perceptual audio coders that they are able to build their own simple audio codec. There is no other source available where a non-professional has access to the true secrets of audio coding.
The hand is quicker than the eye. In many cases, so is digital video. Maintaining image quality in bandwidth- and memory-restricted environments is quickly becoming a reality as thriving research delves ever deeper into perceptual coding techniques, which discard superfluous data that humans cannot process or detect. Surveying the topic from a Human Visual System (HVS)-based approach, Digital Video Image Quality and Perceptual Coding outlines the principles, metrics, and standards associated with perceptual coding, as well as the latest techniques and applications. This book is divided broadly into three parts. First, it introduces the fundamental theory, concepts, principles, and techniques underlying the field, such as the basics of compression, HVS modeling, and coding artifacts associated with current well-known techniques. The next section focuses on picture quality assessment criteria; subjective and objective methods and metrics, including vision model based digital video impairment metrics; testing procedures; and international standards regarding image quality. Finally, practical applications come into focus, including digital image and video coder designs based on the HVS as well as post-filtering, restoration, error correction, and concealment techniques. The permeation of digital images and video throughout the world cannot be understated. Nor can the importance of preserving quality while using minimal storage space, and Digital Video Image Quality and Perceptual Coding provides the tools necessary to accomplish this goal. Instructors and lecturers wishing to make use of this work as a textbook can download a presentation of 786 slides in PDF format organized to augment the text. accompany our book (H.R. Wu and K.R. Rao, Digital Video Image Quality and Perceptual Coding, CRC Press (ISBN: 0-8247-2777-0), Nov. 2005) for lecturers or instructor to use for their classes if they use the book.
Digital television is a multibillion-dollar industry with commercial systems now being deployed worldwide. In this concise yet detailed guide, you will learn about the standards that apply to fixed-line and mobile digital television, as well as the underlying principles involved. The digital television standards are presented to aid understanding of new systems in the market and reveal the variations between different systems used throughout the world. Discussions of source and channel coding then provide the essential knowledge needed for designing reliable new systems. Throughout the book the theory is supported by over 200 figures and tables, whilst an extensive glossary defines practical terminology. This is an ideal reference for practitioners in the field of digital television. It will also appeal to graduate students and researchers in electrical engineering and computer science, and can be used as a textbook for graduate courses on digital television systems.
In this book, two leaders of the MPEG-4 standards community offer an in-depth, targeted guide to the MPEG-4 standard and its use in real, cutting-edge applications. The authors demonstrate how MPEG-4 addresses the rapidly evolving needs of telecommunications, broadcast, interactive, and converged applications more successfully than any previous standard.
The Practical Guide to MPEG 4 offers an up to date introduction to this important interactive and multimedia compression standard (including MPEG-4 Part 10), with real examples and information as to how and where this new technology should be used. All aspects of MPEG-4 that are relevant in today's technical landscape are described in this book, including video and audio creation, production, distribution, reception and consumption environment. This book explains everything you really need to know in jargon-free language: interactive systems, content management, deployment, licensing and business models.
This book describes the fundamentals and details of MPEG-2Systems technology Written by an expert in the field, this book examines the MPEG-2system specification as developed in the early 1990’s, aswell as its evolution into the fourth edition of the MPEG-2 systemsstandard, published in 2013. While MPEG-2 systems will continue toevolve further, this book describes the MPEG-2 system functionalityas of October 2013. Furthermore, relevant background information isprovided. The discussion of MPEG-2 system functionality requiresknowledge of various fundamental issues, such as timing, andsupported content formats. Therefore also some basic information onvideo and audio coding is provided, including their evolution. Alsoother content formats supported in MPEG-2 systems are described, asfar as needed to understand MPEG-2 systems. Ordered logically working from the basics and backgroundthrough to the details and fundamentals of MPEG-2 transport streamsand program streams Explores important issues within the standardization processitself Puts the developments on MPEG-2 systems into historicperspective Includes support of 3D Video and transport of AVC, SVC andMVC Concludes with additional issues such as real-time interface,delivery over IP networks and usage by application standardizationbodies Predicts a continuing promising future for MPEG-2 transportstreams

A multimedia system needs a mechanism to communicate with its environment, the Internet, clients, and applications. MPEG-7 provides a standard metadata format for global communication, but lacks the framework to let the various players in a system interact. MPEG-21 closes this gap by establishing an infrastructure for a distributed multimedia frame
