Digital Television Systems
This page intentionally left blank Digital Television Systems Digital television is a multibillion-dollar industry with commercial systems now being deployed worldwide. In this concise yet detailed guide, you will learn about the standards that apply to fixed-line and mobile digital television, as well as the underlying principles involved, such as signal analysis, modulation techniques, and source and channel coding. The digital television standards, including the MPEG family, ATSC, DVB, ISDTV, DTMB, and ISDB, are presented toaid understanding ofnew systems in the market and reveal the variations between different systems used throughout the world. Discussions of source and channel coding then provide the essential knowledge needed for designing reliable new systems.Throughout the book the theory is supported by over 200 figures and tables, whilst an extensive glossary defines practical terminology.Additional background features, including Fourier analysis, probability and stochastic processes, tables of Fourier and Hilbert transforms, and radiofrequency tables, are presented in the book’s useful appendices. This is an ideal reference for practitioners in the field of digital television. It will alsoappeal tograduate students and researchers in electrical engineering and computer science, and can be used as a textbook for graduate courses on digital television systems. Marcelo S. Alencar is Chair Professor in the Department of Electrical Engineering, Federal University of Campina Grande, Brazil.

The simulation results show the difference Microcellular of propagation in indoor and outdoor environment at higher frequencies and draw a special 3D ray tracing attention on the impact of diffuse scattering at 28 GHz and 60 GHz. In a simple outdoor System performance microcellular environment with a valid LOS link between the transmitter and a receiver, 5G the mean received signal at 28 GHz and 60 GHz was found around 5.7 dB and 13 dB Millimeter wave frequencies inferior in comparison with signal level at 15 GHz. -
Digital Dividend: Insights for Spectrum Decisions

No part of this publication may be reproduced, by any means whatsoever, without the prior written permission of ITU. Foreword The rising importance of the radio spectrum in the world means that the way in which it is managed is vital for economical and societal development. As spectrum is freed up by the transition of analogue television services to digital and by the use of ever more advanced transmission and coding digital broadcasting technology, national and international spectrum decision makers are faced with the question of how to allocate the ‘digital dividend’ resulting from the spectrum efficiencies gained by this process in the frequency bands currently allocated to broadcasting. Although reallocation of spectrum is an important aspect of the transition to digital terrestrial tele- vision, there are other reasons for introducing or evolving the digital terrestrial television services. In addition to gaining spectrum efficiency, it will bringconsumer benefits(more choice and quality in television services) and industry benefits(new revenue streams and business models). By definition, the process by which the digital dividend will be allocated is closely related to the introduction or evolution of digital terrestrial television services. -

UHF-Band TV Transmitter for TV White Space Video Streaming Applications Hyunchol Shin1,* · Hyukjun Oh2
JOURNAL OF ELECTROMAGNETIC ENGINEERING AND SCIENCE, VOL. 19, NO. 4, 227~233, OCT. 2019 https://doi.org/10.26866/jees.2019.19.4.227 ISSN 2671-7263 (Online) ∙ ISSN 2671-7255 (Print) UHF-Band TV Transmitter for TV White Space Video Streaming Applications Hyunchol Shin1,* · Hyukjun Oh2 Abstract This paper presents a television (TV) transmitter for wireless video streaming applications in TV white space band. The TV transmitter is composed of a digital TV (DTV) signal generator and a UHF-band RF transmitter. Compared to a conventional high-IF heterodyne structure, the RF transmitter employs a zero-IF quadrature direct up-conversion architecture to minimize hardware overhead and com- plexity. The RF transmitter features I/Q mismatch compensation circuitry using 12-bit digital-to-analog converters to significantly im- prove LO and image suppressions. The DTV signal generator produces an 8-vestigial sideband (VSB) modulated digital baseband signal fully compliant with the Advanced Television System Committee (ATSC) DTV signal specifications. By employing the proposed TV transmitter and a commercial TV receiver, over-the-air, real-time, high-definition video streaming has been successfully demonstrated across all UHF-band TV channels between 14 and 69. This work shows that a portable hand-held TV transmitter can be a useful TV- band device for wireless video streaming application in TV white space. Key Words: DTV Signal Generator, RF Transmitter, TV Band Device, TV Transmitter, TV White Space. industry-science-medical (ISM)-to-UHF-band RF converters I.
