Описание: This book has become "the bible" for the new hires, as well as for anyone that needs to have the basic vocabulary in broadcast. This new edition builds on what worked in the previous one, while adding new standards and defining emerging digital technologies that are revolutionizing the field.
Описание: This book investigates adaptive physical-layer beamforming and resource allocation that ensure reliable data transmission in the multi-antenna broadcast channel. The book provides an overview of robust optimization techniques and modelling approximations to deal with stochastic performance metrics. One key contribution of the book is a closed-form description of the achievable rates with unlimited transmit power for a rank-one channel error model. Additionally, the book provides a concise duality framework to transform mean square error (MSE) based beamformer designs, e.g., quality of service and balancing optimizations, into equivalent uplink filter designs. For the algorithmic solution, the book analyses the following paradigm: transmission to receivers with large MSE targets (low demands) is switched off if the transmit power is low. The book also studies chance constrained optimizations for limiting the outage probability. In this context, the book provides two novel conservative outage probability approximations, that result in convex beamformer optimizations. To compensate for the remaining inaccuracy, the book introduces a post-processing power allocation. Finally, the book applies the introduced beamformer designs for SatCom, where interference from neighboring spotbeams and channel fading are the main limitations.

The book illustrates how change in distribution technology is accelerating the need for broadcasters around the world to adapt their content distribution strategy and how it will impact the portfolios of content they offer.
Описание: What you need to know to survive, long term.Interests between broadcasters and telecom people are blurring. Technical operations and design engineers in one field are increasingly required to deal with practices and techniques in the other. The problem is expectations and terminology differences aren't recognized until it's too late.Take "Quality of Service." The telecom people specify a percentage of the time that the service is guaranteed to be available. The down time may be very, very small. But, if it occurs during a high-priced commercial in the Super Bowl, it is very, very serious for the broadcaster. Practical IP and Telecom for Broadcast Engineering and Operations teaches the technology and how to structure it and make sure the finances work in your favor.Learn how to: * Define communications circuit, equipment, facilities and services used in broadcast engineering and operations.* Evaluate suppliers as well as their products and services.* Prepare technical specifications and requests for bids, proposals required in competitive procurement actions.* Conduct communications operational effectiveness and cost audits.* Prepare communications cost management strategies and plans.* Plan and execute capital projects.* Survive Long-TermCritical for engineers, technicians, and managers engaged in designing, installing, testing, and maintaining equipment and network services for program content, training material, or audio/video conferencing. Valuable knowledge for planning, design, integration and operation of communications equipment, facilities and services used in broadcast operations, training and conferencing applications.Fred Huffman is a systems engineer with Athens Olympic Broadcasting, the Host Broadcaster for the 2004 Games. He has more than 35 years experience in technical and management roles in broadcasting and telecommunications fields. This work is largely a reflection of that experience, captured in a way that introduces the reader to technical aspects of IP, ATM and classical telecom, along with business essentials such as contracts, tariffs, project planning, budgeting and long range planning.
Описание: This award-winning volume analyzes the MIMO channel`s maximum high-power performance and answers the fundamental question of feasibility in quality-of-service based optimizations characterized by inelastic traffic that features strict delay constraints.

Описание:
This book presents the current research on safety message dissemination in vehicular networks, covering medium access control and relay selection for multi-hop safety message broadcast. Along with an overall overview of the architecture, characteristics, and applications of vehicular networks, the authors discuss the challenging issues in the research on performance improvement for safety applications, and provide a comprehensive review of the research literature.
A cross layer broadcast protocol is included to support efficient safety message broadcast by jointly considering geographical location, physical-layer channel condition, and moving velocity of vehicles in the highway scenario. To further support multi-hop safety message broadcast in a complex road layout, the authors propose an urban multi-hop broadcast protocol that utilizes a novel forwarding node selection scheme. Additionally, a busy tone based medium access control scheme is designed to provide strict priority to safety applications in vehicle-to-infrastructure communications.
This book offers useful insights into protocol design and inspires a new line of thinking in performance improvements for safety applications in vehicular networks. It is a valuable resource for professionals, researchers, or advanced-level students working in vehicular networks or quality of service.

Описание: Hitler’s regime invested heavily into radio as the most modern media of its era. First in Germany, later in Austria and the Sudetenland, Joseph Goebbels motivated his Volksgenossen to become active radio listeners. But what approach did the regime take to the first non-German people occupied – the Czechs? How would Czech Radio’s staff and listeners respond to Nazi-dominated programming? What strategies of defiance and what options for cooperation existed? What role did Nazism’s core theme of anti-Semitism play? Which Czech societal groups did the Nazis try to reach most? This book casts a spotlight on the effects of the occupation authorities’ policies on specific programming content, as well as on radio as a medium in the so-called Protectorate of Bohemia and Moravia.

The 20th century was a time of rapid expansion in media industries, as well as of accelerating demands for equality and recognition for women. While women's agency has typically been defined through the domestic sphere, the introduction of media into the home destabilised firm boundaries between public and private spheres.
Gender and Media in the Broadcast Age demonstrates how women as media producers and audiences in three countries with public service broadcasters (UK, Canada and Australia) have contributed to changes in our understandings of public and private. Justine Lloyd offers a new way of understanding how tremendous changes in social definitions of gender roles played out in media forms worldwide during this period through the notion of 'intimate geographies'. Women's participation in media continues to be a key challenge to notions of the public sphere and the book concludes that profound changes initiated in the broadcast era are unfinished in the age of digital media. Lloyd therefore provides rich and valuable evidence of the dynamic relationship between media texts, producers and audiences that is relevant to contemporary debates about a growing gender 'apartheid' in a mediated culture.
Описание: With detailed, practical information on video, audio, and broadcast transmission systems from dozens of the field`s foremost experts, The SBE Broadcast Engineering Handbook is the hands-on guide to broadcast station design and maintenance.

Описание: This book discusses opportunities for broadcasters that arise with the advent of broadband networks, both fixed and mobile. It discusses how the traditional way of distributing audio-visual content over broadcasting networks has been complemented by the usage of broadband networks. The author shows how this also gives the possibility to offer new types of interactive or so-called nonlinear services. The book illustrates how change in distribution technology is accelerating the need for broadcasters around the world to adapt their content distribution strategy and how it will impact the portfolios of content they offer.
