Product Description

This book explains the fundamentals of how MPEG works and how MPEG is used in cable television, satellite systems, mobile telecom and Internet television systems. You will discover the basics of audio and video digitization and compression and the standard formats that are used in MPEG files. Introduction to MPEG explains the processes that control media flow and timing synchronization along with how MPEG transmission can monitor and control audio and video quality. You will discover about video compression, streaming services and media control protocols. MPEG has the capability of providing multiple media channels including data channels that can provide media information such as play list titles, artists and media descriptions. You will learn how these channels are combined and time synchronized along with how to manage quality of service (QoS). You will learn how MPEG audio coders can range from low complexity (layer 1) to high complexity (layer 3) including a new AAC that has improved compression performance than MP3. MPEG video coders range from simple digital video compression technologies used in MPEG-1 to complex multi-object compression used in MPEG-4. Various compression technologies such as motion estimation and compression scalability are described. Discover how the MPEG system groups image elements (pixels) within each image (frame) into small blocks, which are grouped into macroblocks. Macroblocks can be combined into slices and each image may contain several slices. Learn how slices make up frames, which come in several different types and how different types of frames can be combined into a group of pictures (GOP). Explanations of how MPEG transmission can combine, send and manage the transmission of multiple forms of information (multimedia) is also provided. You will learn that MPEG systems are composed of various types of streams ranging from the basic raw data stream (elementary streams) to stream that contain a single television video (a program stream) or a stream that combines multiple programs (transport streams). The different frame types including independent reference frames (I-frames), predicted frames (P-frames), bi-directionally predicted frames (B-Frames) and DC frames (basic block reference levels) are described. Learn how MPEG transmission systems regularly broadcast tables that describe programs, program components or other information that is related to the delivery and decoding of programs. Discover how MPEG standards use profiles to define required protocols and actions that enable the providing of features and services for particular MPEG applications. These applications range from providing standard television services over a broadcast system to providing video services on a mobile wireless network. Some of the most important topics featured are: · How MPEG Works · Audio Compression · Video Compression · Digital Quantization · Transmission Formats · Media Streams · Frame Types · Program Tables · Channel Multiplexing · Profiles and Levels

Customer Reviews

Does exactly what the title says
Make no mistake about it, this book will not make you an MPEG or Video compression expert. What it does, as its title says, is that it teaches the basics of what video compression is, why it is used, and how it is implemented. It covers the basics of compression techniques and all the processes an image must go through (DCT, zig-zag, etc). It doesn't go too far into details about each step of the process, but then again it's only an introduction.

A good executive summary, but no technical details
This book gives an overview of MPEG technology that would be appropriate for a manager of a software development team who knows nothing about MPEG and wants to understand the terminology. It would not be useful as a technical reference to a developer. For example, the book will explain that H.264 compresses to about half the size of MPEG-1, but won't explain how the compression works. The whole book only takes a couple of hours to read.

Too many mistakes in simplification
Do not buy this book. The concepts are over simplified to the point of being incorrect. I am a professional engineer working for the largest broadcaster in the USA. I bought the book to further my understanding of MPEG. I was looking for an introduction but this book is a detriment to an accurate understanding of the basics of MPEG. I believe this book was produced to make money, not to add to your understanding of MPEG. Do not buy this book.
