What today’s TV engineers need to know about working with digital systems

This book helps systems engineers, designers, and managers in TV broadcasting make a smooth transition from analog to digital technologies. With an emphasis on RF transmission rather than baseband signal processing, it offers in a single resource a complete discussion of the digital TV signal, from the input to the transmitter to the output of the receiving antenna.

Industry expert Gerald Collins provides clear, up-to-date explanations that build upon experience engineers already have with analog technology, including comparisons between analog and digital systems, factors affecting the performance of VHF and UHF stations, and down-to-earth discussions of modern high-power RF filters. Plus, he provides over 150 high-quality illustrations and tables as well as extensive references for readers wishing to pursue the subject more in depth. The discussion includes:

• Major digital TV transmission standards
• Key performance parameters of interest to RF engineers
• The theory of operation and practical implementation of major system components
• Factors affecting propagation of digital TV signals
• Results of field testing of DTV systems
• Performance data on the American ATSC, the European DVB, and the Japanese ISDB-T systems

The recent demise of the independent television companies and the expansion of satellite and cable networks has led to an explosion in small, independent production facilities. In parallel with this development has been a steady increase in media training and a major expansion in corporate video facilities. The Video Studio is written for everyone contemplating setting-up a professional installation, whether studio or location based. The Video Studio shows how to estimate the scale of investment required and, depending on the nature and frequency of use of the facility, the layout of technical areas and the function of the main items of equipment is described in easy to understand language. In short this is a nuts and bolts approach to planning and operating a studio of 150 square metres or less. Completely updated to take account of all the recent technological advances which have taken place, the book now covers: DAT, timecode, digital compression, non-linear editing and all current digital video formats.

The explosive growth of network, multimedia and wireless technology is fundamentally changing the way people communicate, fueling demand for reliable real-time transmission of image and video data.

This unique text/reference systematically examines the issues in distributed video coding (DVC) and multiple description coding (MDC), two novel techniques designed to address the problems of conventional image and video compression coding. The book begins with a state-of-the-art survey of the topic, before proposing new methods for improving the performance of image and video transmission using DVC and MDC. Covering all fundamental concepts and core technologies, the chapters can also be read as independent and self-sufficient, describing each methodology in sufficient detail to enable readers to repeat the corresponding experiments easily.

Topics and features: provides a broad overview of DVC and MDC, from the basic principles to the latest research; covers sub-sampling based MDC, quantization based MDC, transform based MDC, and FEC based MDC; discusses Sleplian-Wolf coding based on Turbo and LDPC respectively, and comparing relative performance; includes original algorithms of MDC and DVC; presents the basic frameworks and experimental results, to help readers improve the efficiency of MDC and DVC; introduces the classical DVC system for mobile communications, providing the developmental environment in detail.

Researchers and engineers will find this book a useful reference on DVC and MDC technologies, and a guide for developing practical applications for DVC and MDC systems. The text will also be of interest to graduate students in image processing and signal processing.

On March 15, 2011, Donald Trump changed television forever. The Comedy Central Roast of Trump was the first major live broadcast to place a hashtag in the corner of the screen to encourage real-time reactions on Twitter, generating more than 25,000 tweets and making the broadcast the most-watched Roast in Comedy Central history. The #trumproast initiative personified the media and tech industries' utopian vision for a multiscreen and communal live TV experience. In Social TV: Multiscreen Content and Ephemeral Culture, author Cory Barker reveals how the US television industry promised-but failed to deliver-a social media revolution in the 2010s to combat the imminent threat of on-demand streaming video. Barker examines the rise and fall of Social TV across press coverage, corporate documents, and an array of digital ephemera. He demonstrates that, despite the talk of disruption, the movement merely aimed to exploit social media to reinforce the value of live TV in the modern attention economy. Case studies from broadcast networks to tech start-ups uncover a persistent focus on community that aimed to monetize consumer behavior in a transitionary industry period. To trace these unfulfilled promises and flopped ideas, Barker draws upon a unique mix of personal Social TV experiences and curated archives of material that were intentionally marginalized amid pivots to the next big thing. Yet in placing this now-forgotten material in recent historical context, Social TV shows how the era altered how the industry pursues audiences. Multiscreen campaigns have shifted away from a focus on live TV and toward all-day "content" streams. The legacy of Social TV, then, is the further embedding of media and promotional material onto every screen and into every moment of life.

We present queueing-based algorithms to calculate the bandwidth required for a video stream so that the three main Quality of Service constraints, i.e., end-to-end delay, jitter and packet loss, are ensured. Conversational and streaming video-based applications are becoming a major part of the everyday Internet usage. The quality of these applications (QoS), as experienced by the user, depends on three main metrics of the underlying network, namely, end-to-end delay, jitter and packet loss. These metrics are, in turn, directly related to the capacity of the links that the video traffic traverses from its source to destination. The main problem that this book addresses is how much bandwidth we should allocate on the path from source to destination of a video traffic flow such that the end-to-end delay, jitter and packet loss of the video packets are within some expected required bounds.

Developing usable, useful, and appealing solutions for the customer or user experience requires customization according to specific users' needs amidst frequently changing physical and social environments. Complex design problems like these require interdisciplinary perspectives that cover software functionality, human interaction and communication experiences, and perceived value. After defining and summarizing current research and development, this book focuses on Mobile TV experience in everyday life, innovative conceptual and participatory design methods, contextual analysis methods, social context for interactive multimedia systems, advanced interaction with mobile digital content, and future trends for the wide range of products and services that will be offered in the decade to come. The Editors have carefully balanced the theoretical and empirical approaches providing a valuable insight into principles and methods, as well as actionable guidelines and recommendations for all those interested in exploring how to achieve the core objectives of usability, usefulness, and social appeal of this new mobile-video technology. The book answers many questions, and raises some new ones that only future technology development and deployment in mobile human-computer interaction and communication can answer.

The only single, comprehensive textbook on all aspects of digital television

Visual quality assessment is an interdisciplinary topic that links image/video processing, psychology and physiology. Many engineers are familiar with the image/video processing; transmission networks side of things but not with the perceptual aspects pertaining to quality. Digital Video Quality first introduces the concepts of human vision and visual quality. Based on these, specific video quality metrics are developed and their design is presented. These metrics are then evaluated and used in a number of applications, including image/video compression, transmission and watermarking.* Introduces the concepts of human vision and vision quality.* Presents the design and development of specific video quality metrics.* Evaluates video quality metrics in the context of image/video compression, transmission and watermarking.* Presents tools developed for the analysis of video quality

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.

What happens when screen time is all the time? In the early 1990s, the phrase “screen time� emerged to scare parents about the dangers of too much TV for kids. Screen time was something to fret over, police, and judge in a low-grade moral panic. Now, “screen time� has become a metric not only for good parenting, but for our adult lives as well. There’s even an app for it! In the streaming era—and with streaming made nearly ubiquitous during COVID-19—almost every aspect of our day is mediated by these bright surfaces. Whether it was ever the real villain in the first place, or merely a convenient proxy for unaddressed familial, social, and institutional failures, screen time is now all the time. Avidly Reads Screen Time is a funny, insightful work of cultural criticism and history about how we define screens, and how they now define us. From Mad Men to iCarly, Vine to FaceTime, binge-watching to doom-scrolling, Phillip Maciak leads us on a sometimes heartwarming, sometimes harrowing tour of the media that brings us together and tears us apart.

Algorithmic recommender systems, deployed by media companies to suggest content based on users' viewing histories, have inspired hopes for personalized, curated media but also dire warnings of filter bubbles and media homogeneity. Curiously, both proponents and detractors assume that recommender systems for choosing films and series are novel, effective, and widely used. Scrutinizing the world's most subscribed streaming service, Netflix, this book challenges that consensus. Investigating real-life users, marketing rhetoric, technical processes, business models, and historical antecedents, Mattias Frey demonstrates that these choice aids are neither as revolutionary nor as alarming as their celebrants and critics maintain-and neither as trusted nor as widely used. Netflix Recommends brings to light the constellations of sources that real viewers use to choose films and series in the digital age and argues that although some lament AI's hostile takeover of humanistic cultures, the thirst for filters, curators, and critics is stronger than ever.

The first history of Spanish-language television in the United States In the most comprehensive history of Spanish-language television in the United States to date, Craig Allen traces the development of two prominent yet little-studied powerhouses, Univision and Telemundo. Allen tells the inside story of how these networks fought enormous odds to rise as giants of mass communication within an English-dominated society. The book begins in San Antonio, Texas, in 1961 with the launch of the first Spanish-language station in the country. From it rose the Spanish International Network (SIN), which would later become Univision. Conceived by Mexican broadcasting mogul Emilio Azcarraga Vidaurreta and created by unsung American television pioneers, Unvision grew to provide a vast amount of international programming, including popular telenovelas, and was the first U.S. network delivered by satellite. After Telemundo was founded in the 1980s by Saul Steinberg and Harry Silverman, the two networks battled over audiences and saw dramatic changes in leadership. Today, Univision and Telemundo are multibillion-dollar television providers that equal ABC, CBS, NBC, and Fox in scale and stature. While Univision remains a beacon of U.S. television's internationalization, Telemundo-owned by NBC-is a worldwide leader in producing Spanish-language programs. Using archival sources and original interviews to reconstruct power struggles and behind-the-scenes intrigue, Allen uses this exciting narrative to question monolingual and Anglo-centered versions of U.S. television history. He demonstrates the endurance, innovation, and popularity of Spanish-language television, arguing that its story is essential to understanding the Latinx history of contemporary America. A volume in the series Reframing Media, Technology, and Culture in Latin/o America, edited by Hector Fernandez L'Hoeste and Juan Carlos Rodriguez

'Essential reading.' - ESQUIRE 'Both absorbing and highly illuminating' - THE BOOKSELLER 'No one understands the intricacies of YouTube like Chris Stokel-Walker' - THE ATLANTIC Two billion people watch YouTube and it reaches deep into everyday lives. Its creators start new trends, popularise new songs and games and make and break new products. Yet while they are famous to billions of mostly young people, they mostly remain a mystery to the general public and mainstream media. What is the secret of their appeal? How do they cope with being in front of the lens - and who is behind their success? More than 100 insiders spoke candidly to teach journalist Chris Stokel-Walker for this first in-depth independent book on YouTube. YouTubers is the only book you need to understand YouTube, its ownership by Google, its deal for stars and its ecosystem of talent managers, advertisers and marketers. It is a richly-layered deep dive into YouTube brimming with lively characters, engaging facts, and influencer case studies. It is an ideal guide for any media studies students, advertisers, brand managers and business people who need to understand YouTube professionally. And for any non-fiction reader interested in a gripping business and technology saga dripping with big money, ruthlessness, determination and ambition. YouTubers starts by charting the platform's launch in a boring 19-second video of the elephant enclosure at San Diego Zoo - which has now had 242 million views. YouTubers then moves onto the first oddball videos before the site found success by showing comedy clips from the TV show Saturday Night Live. YouTubers reveals how YouTube saw off its emerging rivals in the online video battle of the 2000s and was bought by the search engine specialist Google. With Google's billions and boosted by smartphones, YouTube became the dominant video platform. Bloggers started to create engaging, fast-cut videos that capitalised on the intimate relationship between creator and user - a 'parasocial' relationship stronger than the bond between TV presenter and viewer. By ceaselessly urging their followers to tap the like, comment and subscribe buttons, these creators helped YouTube's rise to global domination. YouTubers speaks to YouTube stars KSI, Hank and John Green and delves into the lives of child star MattyB, the training camp for aspiring teenage bloggers, the YouTube stunts that go wrong and the increasing efforts of creators to earn money from Patreon. And it tackles the platform's Muslim extremism, red-pilling, and its content guidelines and censorship. YouTubers asks how YouTube can take on the threat from other big platforms such as Instagram and Facebook. In short, YouTubers tells the riveting story of the exponential growth of YouTube from single home video to global tech phenomenon. It is the only book you need on YouTube. Extract Introduction One spring afternoon Casey Neistat uploaded a video lasting five minutes and twenty-two seconds to YouTube. In the style of so many YouTubers, he looked straight into the camera and aired his opinion on a matter of importance. As the elder statesman on the platform, Neistat's words carry weight. He can make or break products and careers - and this video was no different. Seconds after he uploaded his video to YouTube via his superfast broadband at his creative headquarters in New York, it was available worldwide to four billion people: everyone on Earth with an internet connection. Millions of Neistat's subscribers instantly received a notification telling them that one of YouTube's most influential stars was again speaking directly to them. Across the world in apartment blocks, restaurants, bedrooms and bathrooms, phones pinged, buzzed and beeped. Hundreds of thousands of people instantly watched what Neistat had to say. Wearing dark glasses, his hair streaked blond, Neistat vented his frustration at the way the media was second-guessing the motivations of YouTubers...
