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.

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).

WiMAX Broadband Wireless Access Technology, based on the IEEE 802.16 standard, is at the origin of great promises for many different markets covering fixed wireless Internet Access, Backhauling and Mobile cellular networks. WiMAX technology is designed for the transmission of multimedia services (voice, Internet, email, games and others) at high data rates (of the order of Mb/s per user). It is a very powerful but sometimes complicated technique. The WiMAX System is described in thousands of pages of IEEE 802.16 standard and amendments documents and WiMAX Forum documents. WiMAX: Technology for Broadband Wireless Access provides a global picture of WiMAX and a large number of details that makes access to WiMAX documents much easier. All the aspects of WIMAX are covered. Illustrations and clear explanations for all the main procedures of WiMAX are pedagogically presented in a succession of relatively short chapters Topics covered include WiMAX genesis and framework, WiMAX topologies, protocol layers, MAC layer, MAC frames, WiMAX multiple access, the physical layer, QoS Management, Radio Resource Management, Bandwidth allocation, Network Architecture, Mobility and Security Features a glossary of abbreviations and their definitions, and a wealth of explanatory tables and figures Highlights the most recent changes, including the 802.16e amendment of the standard, needed for Mobile WiMAX Includes technical comparisons of WiMAX vs. 802.11 (WiFi) and cellular 3G technologies This technical introduction to WiMAX, explaining the rather complex standards (IEEE 802.16-2004 and 802.16e) is a must read for engineers, decision-makers and students interested in WiMAX, as well as other researchers and scientists from this evolving field.
