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. With over 29 years of teaching and research experience, he has published eight technical books and more than 200 scientific papers. He is Founder and President of the Institute for Advanced Studies in Communications (Iecom) and has consulted for several companies and R&D agencies. -

LG Electronics U.S.A., Inc. (“LG Electronics”) hereby submits these comments in response to the Notice of Proposed Rulemaking (“Notice”) released by the National Telecommunications and Information Administration (“NTIA”) on July 25, 2006,1 concerning the agency’s implementation and administration of the digital-to-analog converter box coupon program mandated by the Digital Television Transition and Public Safety Act of 2005 (the “DTV Act”).2 With a firm deadline now in place for full-power television stations to cease analog broadcasting, it is imperative that the coupon program be conducted in a manner that not only minimizes the burden on those consumers requiring converter boxes but also maximizes the number of Americans able to enjoy the benefits of digital technology. In this regard, LG Electronics applauds NTIA for the comprehensive Notice, which obviously recognizes the critical importance of this final component to the nation’s 1 71 Fed.

Ensuring PMCP/PSIP Interoperability
June 30, 2008 Ensuring PMCP/PSIP Interoperability Recognizing the need for improved industry-wide PMCP interoperability, and thus more accurate PSIP, the ATSC has formed a new Working Group on PSIP Workflow Interoperability, PC-7. This group, reports to the ATSC’s Planning Committee and is chaired by Chris Lennon of Harris Corporation, who provided this contribution to TV TechCheck. For those not familiar with it, PMCP (ATSC Standard A/76B) is the Programming Metadata Communication Protocol. It provides a standardized means of communicating PSIP-related data among the systems that manage it. PMCP has been around for some time, and has recently enjoyed a significant uptake in the industry as interest in and awareness of the need for dynamic, accurate PSIP increases. Part of the scope of the ATSC Planning Committee is to “support the use of ATSC standards and recommended practices through activities such as education, training, demonstrations and fostering interoperability.” The goal of the PC-7 Working Group is to assemble a group of broadcasters and vendors who are implementing (or plan to implement) dynamic PSIP by way of PMCP interfaces between systems such as listing services, program management, traffic, automation, and PSIP generator systems. The group will work to improve interoperability of these systems by way of information exchange regarding PMCP and implementation issues, both on regular conference calls, and at one or more in-person interoperability sessions in Toronto in late Fall 2008. The PC-7 Working Group hopes to provide members a forum in which vendors and broadcasters can work out interoperability details in an open, cooperative environment, benefiting not only the vendors, but the broadcasters who will be implementing these interfaces. -

Mobile TV Technologies Zahid Ghadialy March 2006 © 2006 Zahid Ghadialy What is Mobile TV Mobile TV Broadcasting allows the user to watch their favourite TV programs such as dramas, news, music, sports and documentaries on their mobile device. The service works by receiving a specialised digital TV broadcast signal from the air in much the same way as televisions at home will do in future. Channel guides will also be broadcast allowing users to keep abreast of the latest programs on air. It is not the same as a streaming video service over 3G or GPRS, but one which is optimised for longer period TV viewing by large numbers of simultaneous users with high picture quality and low battery power consumption.
