Book Description
Today, more than 80% of the data transmitted over networks and archived on our computers, tablets, cell phones or clouds is multimedia data - images, videos, audio, 3D data. The applications of this data range from video games to healthcare, and include computer-aided design, video surveillance and biometrics. It is becoming increasingly urgent to secure this data, not only during transmission and archiving, but also during its retrieval and use. Indeed, in today’s "all-digital" world, it is becoming ever-easier to copy data, view it unrightfully, steal it or falsify it. Multimedia Security 1 analyzes the issues of the authentication of multimedia data, code and the embedding of hidden data, both from the point of view of defense and attack. Regarding the embedding of hidden data, it also covers invisibility, color, tracing and 3D data, as well as the detection of hidden messages in an image by steganalysis.

Book Description
Next Generation Mobile Broadcasting provides an overview of the past, present, and future of mobile multimedia broadcasting. The first part of the book—Mobile Broadcasting Worldwide—summarizes next-generation mobile broadcasting technologies currently available. This part covers the evolutions of the Japanese mobile broadcasting standard ISDB-T One-Seg, ISDB-Tmm and ISDB-TSB; the evolution of the South Korean T-DMB mobile broadcasting technology AT-DMB; the American mobile broadcasting standard ATSC-M/H; the Chinese broadcasting technologies DTMB and CMMB; second-generation digital terrestrial TV European standard DVB-T2 and its mobile profile T2-Lite; and the multicast/broadcast extension of 4G LTE cellular standard E-MBMS. This part includes a chapter about a common broadcast specification of state-of-the-art 3GPP and DVB standards to provide a broadcast overlay optimized for mobile and operated in conjunction with a broadband unicast access. It also contains an overview chapter on a new High-Efficiency Video Coding (HEVC) standard that is expected to provide significantly improved coding efficiency compared to current MPEG-4 AVC video coding. The second part of the book—Next-Generation Handheld DVB Technology: DVB-NGH —describes the latest mobile broadcast technology known as Digital Video Broadcasting-Next-Generation Handheld (DVB-NGH), which is expected to significantly outperform all existing technologies in both capacity and coverage. DVB-NGH introduces new technological solutions that along with the high performance of DVB-T2 make DVB-NGH a powerful next-generation mobile multimedia broadcasting technology. In fact, DVB-NGH can be regarded as the first 3G broadcasting system because it allows for the possibility of using multiple input multiple output MIMO antenna schemes to overcome the Shannon limit of single antenna wireless communications. DVB-NGH also allows the deployment of an optional satellite component forming a hybrid terrestrial-satellite network topology to improve coverage in rural areas where the installation of terrestrial networks is economically unfeasible. Although the commercial deployment of DVB-NGH is nowadays unclear after its standardization, it will be a reference point for future generations of digital terrestrial television technologies. Edited by a member of the DVB-NGH standardization group, the book includes contributions from a number of standardization groups worldwide—including Digital Video Broadcasting (DVB) in Europe; Advanced Television Systems Committee (ATSC) in the US, Korea, Japan, and China; Third Generation Partnership Project (3GPP); and the Moving Picture Experts Group (MPEG).

Book Description
There are lots of introductory C books, but this is the first one that has the no-nonsense, practical approach that has made Nutshell Handbooks® famous.C programming is more than just getting the syntax right. Style and debugging also play a tremendous part in creating programs that run well and are easy to maintain. This book teaches you not only the mechanics of programming, but also describes how to create programs that are easy to read, debug, and update.Practical rules are stressed. For example, there are fifteen precedence rules in C (&& comes before || comes before ?:). The practical programmer reduces these to two: Multiplication and division come before addition and subtraction. Contrary to popular belief, most programmers do not spend most of their time creating code. Most of their time is spent modifying someone else's code. This books shows you how to avoid the all-too-common obfuscated uses of C (and also to recognize these uses when you encounter them in existing programs) and thereby to leave code that the programmer responsible for maintenance does not have to struggle with. Electronic Archaeology, the art of going through someone else's code, is described.This third edition introduces popular Integrated Development Environments on Windows systems, as well as UNIX programming utilities, and features a large statistics-generating program to pull together the concepts and features in the language.

Book Description
Celebrate the rebirth of the world's most stunning high-performance automobile. Porsche made history when it brought turbocharging to the racing world in the form of the 917. When strict regulations regarding engine displacement took away the option of bigger engines, manufacturers turned to forced induction. In its wildest trim, the original 12-cylinder turbocharged Porsche racing engine yielded as much as 1,400 horsepower! Porsche's official philosophy was that racing cars must have a connection to street cars, so it was preordained that Porsche would eventually produce a turbocharged version of its air-cooled flat-six cylinder engine. The resulting 930 Turbo appeared in the spring of 1975 in Europe. Acceleration from 0 to 100 kilometers per hour took a scant 5.5 seconds, and its top speed was 155 miles per hour. The Turbo's distinctive rear wing let the world know that this was something very special. It was nothing less than the rebirth of the high-performance automobile. At a time when the big-block engines in America's so-called "muscle cars" were putting out 180 horsepower and the engines in exotic supercars weren't much more ambitious, the lightweight Porsche was a genuine rocket. Porsche Turbo: The Inside Story of Stuttgart's Turbocharged Road and Race Cars celebrates Porsche's five decades of turbocharged supercar performance, both on the track and on the street. It covers all of the major racing cars as well as the turbocharged street cars, including the 930, 935, 924, 944, 968, 911, and Cayenne Panamera. Don't let this one fly past you!

Book Description
GM LS-series engines are some of the most powerful, versatile, and popular V-8 engines ever produced. They deliver exceptional torque and abundant horsepower, are in ample supply, and have a massive range of aftermarket parts available. Some of the LS engines produce about 1 horsepower per cubic inch in stock form--that's serious performance. One of the most common ways to produce even more horsepower is through forced air induction--supercharging or turbocharging. Right-sized superchargers and turbochargers and relatively easy tuning have grown to make supercharging or turbocharging an LS-powered vehicle a comparatively simple yet highly effective method of generating a dramatic increase in power. In the revised edition of How to Supercharge & Turbocharge GM LS-Series Engines, supercharger and turbocharger design and operation are covered in detail, so the reader has a solid understanding of each system and can select the best system for his or her budget, engine, and application. The attributes of Roots-type and centrifugal-type superchargers as well as turbochargers are extensively discussed to establish a solid base of knowledge. Benefits and drawbacks of each system as well as the impact of systems on the vehicle are explained. Also covered in detail are the installation challenges, necessary tools, and the time required to do the job. Once the system has been installed, the book covers tuning, maintenance, and how to avoid detonation so the engine stays healthy. Cathedral, square, and D-shaped port design heads are explained in terms of performance, as well as strength and reliability of the rotating assembly, block, and other components. Finally, Kluczyk explains how to adjust the electronic management system to accommodate a supercharger or turbocharger. How to Supercharge and Turbocharge GM LS-Series Engines is the only book on the market specifically dedicated to forced air induction for LS-series engines. It provides exceptional guidance on the wide range of systems and kits available for arguably the most popular modern V-8 on the market today.
