Writing for readers with a background in electronics, some knowledge of analog television, and a basic digital background, Benoit (Philips Semiconductors, France) intends this book as a summary and starting point rather than a handbook for experts. He describes the complex problems that had to be solved in order to define reliable standards for broadcasting digital pictures, and he explains the solutions chosen for the European digital video broadcasting (DVB) system based on the international MPEG-2 compression standard. The book ends with a description of a digital integrated receiver decoder, or set-top box, and a discussion of future prospects. Adapted and translated by the author from a 1996 work published in French (Paris: Dunod). The second edition adds a chapter on software interoperability.

Spatial and Temporal Variations of the Turbulent Fluxes of Heat, Momentum, and Water Vapor Over Lake Ontario During IFYGL by Bradford R. Bean Pdf
During the 1972 IFYGL 'alert' periods, the highly instrumented NOAA/RFF/DC-6 aircraft was used to record the time series of wind, temperature, and water vapor at heights ranging from 18 to 300 m above the surface of Lake Ontario. The aircraft was equipped with a gust probe system, a fast response thermistor, a microwave refractometer (for water vapor measurements), and a downward-pointing IR system; as well as the normal in-flight measurement of standard meteorological parameters. The time series records have been found to display a highly intermittent nature. This is especially the case for evaporation when, in the fall, Polar Continental outbreaks move across the lake. In particular, such an outbreak of cold dry air moved across the lake at 12-15 m s−1 on 9 October 1972. This resulted in the air temperature at 30 m above the lake to drop from 12 to 6 C while the evaporation rate increased to more than 1 cm day−1. This may be compared with the 0.5 cm day−1 normal evaporation observed in the tropics during BOMEX. Furthermore, IR lake surface temperatures show cold regions (~5 C) along the north shore, presumably due to strong upwelling, while the center and south shore regions of the lake were of the order of 12 to 15C. The turbulent, flux quantities of momentum, heat, and water vapor were obtained by the eddy correlation technique and their spectra were determined at several locations over the lake surface for 3-minute sampling lengths. At the aircraft speed of 92 m s−1, this represents a flight path of ~17 km for both along wind and constant fetch patterns. The spectra demonstrate the tendency for the peak value to march to higher wavelengths with increasing height.
Border Cinema by Monica Hanna,Rebecca A. Sheehan Pdf
The rise of digital media and globalization’s intensification since the 1990s have significantly refigured global cinema’s form and content. The coincidence of digitalization and globalization has produced what this book helps to define and describe as a flourishing border cinema whose aesthetics reflect, construct, intervene in, denature, and reconfigure geopolitical borders. This collection demonstrates how border cinema resists contemporary border fortification processes, showing how cinematic media have functioned technologically and aesthetically to engender contemporary shifts in national and individual identities while proposing alternative conceptions of these identities to those promulgated by the often restrictive current political rhetoric and ideologies that represent a backlash to globalization.
Digital Techniques in Echocardiography by J.R. Roelandt Pdf
Cardiac ultrasound has rapidly developed into one of the most important clinical methods for diagnosis and follow-up of patients with heart disease and has changed the practice of cardiology permanently. In addition to improving image quality, most of the progress relies on digital image acquisition, storage, and quantitative analysis equipment. Automatic endocardial detection and three dimensional reconstruction are now being developed. The progress with contrast echocardiography for myocardial perfusion imaging and results with tissue characterization is slow, but ever increasing, illustrating that the full potential of the method has not yet been explored. All of these digital techniques are extensively dealt with in this volume. Computerized tools will help the clinical cardiologists in their daily practice and stimulate further development to gen uinely improve patient care in the coming years. We wish to thank the authors to this volume for their excellent contribution and Mrs. T. van der Kolk for secretarial assistance. IX Contributors F.J. ten Cate Thorax Center, Erasmus University, P.O.

Digital Signal Processing with Matlab Examples, Volume 1 by Jose Maria Giron-Sierra Pdf
This is the first volume in a trilogy on modern Signal Processing. The three books provide a concise exposition of signal processing topics, and a guide to support individual practical exploration based on MATLAB programs. This book includes MATLAB codes to illustrate each of the main steps of the theory, offering a self-contained guide suitable for independent study. The code is embedded in the text, helping readers to put into practice the ideas and methods discussed. The book is divided into three parts, the first of which introduces readers to periodic and non-periodic signals. The second part is devoted to filtering, which is an important and commonly used application. The third part addresses more advanced topics, including the analysis of real-world non-stationary signals and data, e.g. structural fatigue, earthquakes, electro-encephalograms, birdsong, etc. The book’s last chapter focuses on modulation, an example of the intentional use of non-stationary signals.
Video Error Concealment Techniques for Multi-Broadcast Reception of Digital TV by Tobias Tröger Pdf
Abstract The transmission of digital TV signals to mobile receivers is often error-prone. As most TV broadcasting techniques provide only moderate error robustness, horizontal lines of consecutive image blocks are lost during decoding of the received video signals. In order to ensure high viewing experiences, these lost slices have to be filled by error concealment techniques. However, the reconstruction qualities of classical approaches which exploit spatial, temporal, or spatio-temporal signal correlations are not convincing yet. In the future, mobile TV receivers will support different broadcasting techniques in parallel. As a result, an erroneous high-resolution video signal and a correctly received low-resolution video signal, both representing the same TV service, will often be available. Focusing on the outlined scenario for multi-broadcast reception of digital TV signals, this thesis introduces the novel category of inter-sequence error concealment algorithms. The basic idea is to fill lost slices of the high-resolution video signal by the interpolated low-resolution video signal. Since the images of this reference signal are often cropped and delayed, robust spatio-temporal image alignment is crucial. By including a pixel-based or a feature-based alignment scheme, the proposed concealment algorithms provide excellent visual qualities and outstanding reconstruction qualities of up to 41 dB PSNR. Classical concealment techniques are outperformed by up to 15 dB PSNR. To further enhance the reconstruction quality, several extensions are introduced. First, the alignment robustness and the interpolation quality are increased. Subsequently, a classical temporal approach is incorporated as an alternative concealment mode to cope with low image qualities of the reference signal. Novel aspects include robust mode selection, enhanced motion estimation, and the reconstruction of the displaced frame differences from the reference signal. As a last extension, spatial refinement tackles blurring of concealed image blocks. Missing spectral components are recovered in a frequency selective way based on approximation and extrapolation principles. By combining all relevant extensions, the PSNR gain adds up to 20 dB with respect to classical concealment. Finally, inter-sequence error concealment is adapted to multi-broadcast reception of two erroneous high-resolution video signals. While spatial alignment can be omitted, classical concealment of blocks, being lost in both video signals, and drift compensation in predictively-coded frames are novel aspects. Again, high visual qualities are obtained and classical concealment is outperformed by up to 15 dB PSNR. Zusammenfassung Der Empfang digitaler Fernsehsignale mit mobilen Endgeräten wird meist durch Übertragungsfehler gestört. Da viele der eingesetzten Übertragungsstandards nur unzureichende Korrekturmechanismen bieten, können bei der Decodierung der empfangenen Videosignale Blockzeilenverluste auftreten. Um die Verlustgebiete zu verschleiern, werden üblicherweise zeitliche, örtliche oder zeitlich-örtliche Signalkorrelationen ausgenutzt. Die dabei erzielte Rekonstruktionsqualität ist jedoch häufig nicht zufriedenstellend. Zukünftig werden mobile Fernsehempfänger mehrere Übertragungsstandards parallel unterstützen. Durch den Einsatz dieser Mehrfachempfänger ist jedes Fernsehprogramm typischerweise in Form eines gestörten, hochauflösenden Videosignals und eines ungestörten, niedrigauflösenden Videosignals verfügbar. Ausgehend vom Mehrfachempfang digitaler Fernsehsignale wird in dieser Arbeit eine neue Gruppe von Verfahren zur Fehlerverschleierung beschrieben. Die grundlegende Idee dieser Ansätze besteht darin, verlorene Bildblöcke des hochauflösenden Videosignals durch Blöcke des interpolierten niedrigauflösenden Referenzsignals zu ersetzen. Da das Referenzsignal häufig nur Bildausschnitte zeigt und zudem meist zeitverzögert eintrifft, ist die korrekte Bestimmung der örtlichen Abbildungsparameter und des zeitlichen Versatzes ausschlaggebend für eine hochqualitative Verschleierung. Durch den Einsatz bildbasierter oder merkmalsbasierter Schätzverfahren werden eine exzellente visuelle Bildqualität und eine außergewöhnlich hohe Rekonstruktionsqualität erzielt. Der Spitzensignal-Rauschabstand beträgt bis zu 41 dB. Herkömmliche Verfahren werden um bis 15 dB übertroffen. Um die Rekonstruktionsqualität weiter zu erhöhen werden zahlreiche Erweiterungen der beschriebenen Verschleierungsansätze vorgeschlagen. Zuerst werden die Zuverlässigkeit der Parameterschätzung und die Interpolationsqualität verbessert. Danach wird ein herkömmliches zeitliches Verschleierungsverfahren integriert, um eine niedrige Bildqualität des Referenzsignals zu kompensieren. Neue Aspekte sind dabei die robuste Wahl des besseren Verschleierungsmodus, eine verbesserte Bewegungsschätzung und die Rekonstruktion des Prädiktionsfehlers unter Verwendung des Referenzsignals. Zuletzt wird die Bildschärfe bereits verschleierter Blöcke erhöht. Dazu werden fehlende Spektralanteile basierend auf frequenzselektiven Approximations- oder Extrapolationsansätzen wiederhergestellt. Durch die Kombination aller relevanten Erweiterungen wird die Rekonstruktionsqualität herkömmlicher Verfahren um bis zu 20 dB übertroffen. Abschließend werden die beschriebenen Fehlerverschleierungsverfahren an ein Szenario für den Mehrfachempfang digitaler Fernsehsignale angepasst, bei dem zwei fehlerhafte hochauflösende Videosignale verfügbar sind. Während die Schätzung der örtlichen Abbildungsparameter entfällt, müssen Bildblöcke, die in keinem der beiden Videosignale korrekt empfangen wurden, durch herkömmliche Verfahren verschleiert werden. Als weitere Neuerung wird ein Verfahren zur Kompensation des Drifteffekts in prädiktiv codierten Bildern vorgeschlagen. Auch bei diesem Empfangsszenario wird eine hohe visuelle Bildqualität erzielt und die Rekonstruktionsqualität herkömmlicher Verfahren um bis zu 15 dB übertroffen.
Error, Ambiguity, and Creativity by Sita Popat,Sarah Whatley Pdf
This book offers a set of eleven discipline-specific chapters from across the arts, humanities, psychology, and medicine. Each contributor considers the creative potential of error and/or ambiguity, defining these terms in the particular context of that discipline and exploring their values and applications. Themes include error in choreography, poetry, media art, healthcare, psychology, critical typography and mixed reality performance. The book emerges from a core question of how dance research and HCI can inform each other through consideration of error, ambiguity and ‘messiness’ as methodological tools. The digital age had heralded the possibility that error could be eradicated by the logic of computers but several chapters focus on glitch in arts practices that exploit errors in computer programmes, or even create programmes specifically to produce errors. Together, the chapters explore how error can take us somewhere different or somewhere new, to develop a new, more interesting way of working.
