Ultra HD es un nuevo estándar para la imagen digital en movimiento. Las organizaciones internacionales de normalización están todavía trabajando en su desarrollo. En una primera fase, se ha propuesto trabajar con una resolución de imagen de 4K, pero aún no se sabe hasta dónde nos llevará esta senda que afecta a las industrias del cine, la televisión y el vídeo. ¿Es un cambio de paradigma o simplemente una suave evolución? ¿Está madura la tecnología para este cambio? ¿Existe realmente una demanda de los usuarios? Hemos tratado de poner en claro algunas de estas cuestiones y entender lo que supone el 4K y la Ultra HD para las cámaras, los sistemas de postproducción y la difusión o archivo de los contenidos. Pretendemos clarificar algunas ideas que puedan ayudar a rellenar lagunas de conocimientos que dificultan la comprensión global del escenario, y desde esa perspectiva hemos redactado estas páginas. Comenzaremos este análisis exponiendo una serie de conceptos básicos y necesarios para entender el potencial y las limitaciones de la ultra alta definición a día de hoy. A continuación, describiremos los distintos formatos y códecs que se están utilizando en la industria audiovisual y sus características técnicas. Se han considerado como entornos de difusión: el cine digital, la televisión, la distribución de contenidos por internet y los discos Blu-ray. Otros apartados se dedicarán a las herramientas para la captación: cámaras, sensores, ópticas y sistemas de grabación; a los sistemas de postproducción, considerando tanto el hardware como el software; a los sistemas de almacenamiento y archivo y, por último, a las mejoras en el sonido que deben de acompañar al incremento de la calidad visual.
First published in St. Petersburg in 1759, F.U.T. Aepinus's Tenuimen theoriae electricilatis el magnetismi was one of the outstanding achievements of eighteenth-century physics. Its rigorous mathematical investigation of electricity and magnetism was an important and innovative departure from the primarily qualitative and nonmathematical treatments that preceded it. P. J. Connor's translation of the original Latin edition is the first to appear in any western European language, and the introductory monograph and notes by R. W. Home provide a far more definitive account of Aepinus's life and work than has heretofore been attempted. Originally published in 1979. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
Roughly once every generation, a powerful, highly influential organization within the Chinese People's Liberation Army releases a new edition of the Science of Military Strategy (SMS), a comprehensive and authoritative study which details the strategic approach that the Chinese military will take in the coming years in response to the threats and challenges facing China. The recent release of a new edition of SMS signals the potential for dramatic shifts in the PLA's approach to a number of strategic questions, but the book remains underutilized by many Western China analysts due to the lack of both an English translation and expert analysis to place these changes into context. China's Evolving Military Strategy aims to bring knowledge of these important developments to a mass audience of China watchers, policymakers, and the broader foreign policy community by providing a sector-by-sector analysis of changes in the PLA's thinking and approach from the previous edition of SMS to the present. Each chapter addresses the implications for a different portion of the Chinese military, ranging from the air, sea, and space domains to cyberspace and electromagnetic warfare, and each is written by one of the world's foremost experts on that subsection of China's military development. China's Evolving Military Strategy will serve as the cornerstone reference for a generation to come on one of China's most important declarations of its military-strategic goals and intentions.
In 2008, U.S. and Iraqi forces defeated an uprising in Sadr City, a district of Baghdad with ~2.4 million residents. Coalition forces’ success in this battle helped consolidate the Government of Iraq’s authority, contributing significantly to the attainment of contemporary U.S. operational objectives in Iraq. U.S. forces’ conduct of the battle illustrates a new paradigm for urban combat and indicates capabilities the Army will need in the future.
The automotive industry appears close to substantial change engendered by “self-driving” technologies. This technology offers the possibility of significant benefits to social welfare—saving lives; reducing crashes, congestion, fuel consumption, and pollution; increasing mobility for the disabled; and ultimately improving land use. This report is intended as a guide for state and federal policymakers on the many issues that this technology raises.
Provocative yet sober, Digital Critical Editions examines how transitioning from print to a digital milieu deeply affects how scholars deal with the work of editing critical texts. On one hand, forces like changing technology and evolving reader expectations lead to the development of specific editorial products, while on the other hand, they threaten traditional forms of knowledge and methods of textual scholarship. Using the experiences of philologists, text critics, text encoders, scientific editors, and media analysts, Digital Critical Editions ranges from philology in ancient Alexandria to the vision of user-supported online critical editing, from peer-directed texts distributed to a few to community-edited products shaped by the many. The authors discuss the production and accessibility of documents, the emergence of tools used in scholarly work, new editing regimes, and how the readers' expectations evolve as they navigate digital texts. The goal: exploring questions such as, What kind of text is produced? Why is it produced in this particular way? Digital Critical Editions provides digital editors, researchers, readers, and technological actors with insights for addressing disruptions that arise from the clash of traditional and digital cultures, while also offering a practical roadmap for processing traditional texts and collections with today's state-of-the-art editing and research techniques thus addressing readers' new emerging reading habits.
Digital media histories are part of a global network, and South Asia is a key nexus in shaping the trajectory of digital media in the twenty-first century. Digital platforms like Facebook, WhatsApp, and others are deeply embedded in the daily lives of millions of people around the world, shaping how people engage with others as kin, as citizens, and as consumers. Moving away from Anglo-American and strictly national frameworks, the essays in this book explore the intersections of local, national, regional, and global forces that shape contemporary digital culture(s) in regions like South Asia: the rise of digital and mobile media technologies, the ongoing transformation of established media industries, and emergent forms of digital media practice and use that are reconfiguring sociocultural, political, and economic terrains across the Indian subcontinent. From massive state-driven digital identity projects and YouTube censorship to Tinder and dating culture, from Twitter and primetime television to Facebook and political rumors, Global Digital Cultures focuses on enduring concerns of representation, identity, and power while grappling with algorithmic curation and data-driven processes of production, circulation, and consumption.
