 MPEG-4 Visual by Iain E. G. Richardson, Following on from the successful MPEG-2 standard, MPEG-4 Visual is enabling a new wave of multimedia applications from Internet video streaming to mobile video conferencing. The new H.264 Advanced Video Coding standard promises impressive compression performance and is gaining support from developers and manufacturers. The first book to cover H.264 in technical detail, this unique resource takes an application-based approach to the two standards and the coding concepts that underpin them.Presents a practical, step-by-step, guide to the MPEG-4 Visual and H.264 standards for video compression.Introduces the basic concepts of digital video and covers essential background material required for an understanding of both standards.Provides side-by-side performance comparisons of MPEG-4 Visual and H.264 and advice on how to approach and interpret them to ensure conformance.Examines the way that the standards have been shaped and developed, discussing the composition and procedures of the VCEG and MPEG standardisation groups. Focussing on compression tools and profiles for practical multimedia applications, this book decodes the standards, enabling developers, researchers, engineers and students to rapidly get to grips with both H.264 and MPEG-4 Visual.
 Virtual Reality Technologies for Future Telecommunications Systems by Algirdas Pakstas, One of the more revolutionary parts of the MPEG-4 International Standard is the Face and Body Animation, or FBA: the specification for efficient coding of shape and animation of human faces and bodies. This specification is a result of collaboration of experts with different backgrounds ranging from image coding and compression to video analysis, computer graphics, as well as speech analysis and synthesis, all sharing a common interest in computer simulation of humans. This book concentrates on the animation of faces. Features include: Sets the MPEG-4 FA specification against the historical background of research on facial animation and model-based coding and provides a brief history of the development of the standard itself. Comprehensive overview of the FA specification with the goal of helping the reader understand how the standard works, what the thinking is behind it, and how it is intended be used. Covers the implementation of the standard on both the encoding and decoding side. Presents several face animation techniques for MPEG-4 FA decoders, as well as architectures for building applications based on the standard. Brings together a collection of applications using the MPEG-4 FA specification. Includes a standard benchmark method for assessing the quality of MPEG-4 FA decoders.The MPEG-4 FA specification is suitable for a wide range of applications not only in telecommunications and multimedia, but also in fields like computer animation and human-computer interfaces. This book will be a valuable companion for practitioners implementing applications based on the MPEG-4 FA specification and those who wish to understand the standard and its implications.
MPEG-1 - MPEG-1 is the designation for a group of audio and video coding standards agreed upon by MPEG (Moving Picture Experts Group). MPEG-1 video is used by the Video CD format. MPEG encoding - MPEG encoding is the process of converting video to the MPEG format for distribution or for archiving on to DVD. MPEG encoding can be done purely in software or by using an MPEG encoding card or a video editing card with in-built MPEG encoding facilities. MPEG-2 - MPEG-2 (1994) is the designation for a group of coding standards for digital audio and video, agreed upon by MPEG (Moving Pictures Experts Group), and published as the ISO/IEC 13818 international standard. MPEG-2 is typically used to encode audio and video for broadcast signals, including direct broadcast satellite and Cable TV. MPEG Layer 2 - MPEG Audio Layer II is a widely used audio format, as it is the default audio format on Video CD and SVCD discs. It is also supported audio format on PAL DVD-Video discs, but not on NTSC discs.

MPEG-7: A formal system for describing multimedia content. The resulting quantized values are then entropy coded. Used for digital satellite TV services like DirectTV, digital cable television signals, and (with slight modifications) for DVD video discs. That means that any MPEG-4 decoder can decode any MPEG-4 decoder can decode any MPEG-4 decoder can decode any MPEG-4 material (of the same type) regardless of the encoder which produced that material. The encoder is not standardized in any way but there are reference implementations available for members that produce valid bitstreams.

MPEG-4: Expands MPEG-1 to support video/audio "objects", 3D content, low bitrate encoding and support for Digital Rights Management.
