FCC Proposes to Allow AM Stations to Voluntarily Transition to All-Digital Broadcasting −
ALERT FCC Proposes to Allow AM Stations to Voluntarily Transition to All-Digital Broadcasting − December 3, 2019 Authors On November 22, 2019, the Federal Communications Commission − John M. Burgett (Commission or FCC) adopted a Notice of Proposed Rulemaking Partner (NPRM) requesting comments on a number of tentative conclusions 202.719.4239 reached by the agency in support of a proposal to authorize AM [email protected] Ari Meltzer radio stations to voluntarily begin broadcasting an all-digital signal. Partner Comments are due 60 days after publication of the NPRM in the 202.719.7467 [email protected] Federal Register and Reply comments are due 90 days after Federal Register publication. Practice Areas The NPRM is based on a Petition for Rulemaking filed by Bryan − Media Broadcasting Corporation and presented in the context of the Telecom, Media & Technology Commission’s broader efforts to revitalize the AM radio service. Under the FCC’s existing rules, AM stations desiring to transmit a digital signal must use the MA1 hybrid service mode, which involves transmitting digital carriers beside and underneath a 5 kHz analog signal. The FCC’s proposal would allow (but not require) AM stations to instead broadcast in the MA3 all-digital mode, which eliminates the modulated analog carrier signal, allowing the digital carriers to move toward center frequency with increased power. Broadcasts in all-digital MA3 mode are not backwards-compatible, meaning they cannot be received by an analog receiver. However, the NPRM identifies several potential benefits of all-digital transmissions, including spectrum efficiency, improved audio quality, reduced interference and the ability to transmit song and title information for audio programming. -

PBS Engineering Technology Advisory Committee ATSC 3.0 Position Paper
PBS Engineering Technology Advisory Committee ATSC 3.0 Position Paper Introduction The PBS Engineering Technical Advisory Committee (ETAC)* has created a working group focused on the pending ATSC 3.0 broadcast transmission standard and its impact on PBS member stations. The ETAC ATSC 3.0 Working Group is made up of Public Television station technology leaders with support from PBS. The current digital broadcast technology was developed in the early 1990s by a large group of industry professionals with overall leadership from the FCC Advisory Committee on Advanced Television Service and the Advanced Television Systems Committee (ATSC).* The standard was published in 1995 and then adopted by the FCC in 1996. In July of 1996, WRAL TV in Raleigh, NC became the first North American television station to broadcast a digital service. In time, the standard we now refer to as ATSC 1.0 was introduced across the country. With the demise of analog television broadcast, it became the operating standard in 2009. ATSC 2.0 was an enhancement of ATSC 1.0, adding new technologies such as advanced video and audio coding and new features such as second screen and Conditional Access. While ATSC 2.0 did become a standard, it was not widely adopted. Many of the capabilities 2.0 enabled, however, were used and expanded on in ATSC 3.0. Technology changes rapidly and the need for an advanced broadcast standard not hampered by the backwards compatibility restraints of ATSC 1.0 is clear. Given consumers’ rapid adoption of mobile and handheld devices for video consumption, it is clear that broadcasters need to adapt to meet current consumer demands and ensure scalability for future needs. -

ATSC 3.0 Transition and Implementation Guide INTRODUCTION This document was developed to provide broadcasters with ATSC 3.0 information that can inform investment and technical decisions required to move from ATSC 1.0 to ATSC 3.0. It also guides broadcasters who are planning for its adoption while also planning for channel changes during the FCC Spectrum Repack Program. This document, finalized September 9, 2016, will be updated periodically as insight and additional information is made available from industry testing and implementation of the new standard. This document was developed by the companies and organizations listed in the Appendix. Updates to the Guide are open to input from all companies and individuals that wish to contribute. Those interested in suggesting changes or updates to this document can do so at [email protected]. 2 ATSC 3.0 Transition and Implementation Guide EXECUTIVE SUMMARY Television service continues to evolve as content distributors – from traditional cable operators to internet-delivered services – utilize the latest technologies to reach viewers and offer a wide variety of program choices. New receiving devices are easily connected to the internet, which relies on the language of Internet Protocol (IP) to transport content. Now terrestrial broadcasters are preparing both for the adoption of an IP-ready next-generation digital TV (DTV) standard and a realignment of the U.S. TV spectrum. Viewers are already buying high-quality displays that respond to 4K Ultra HDTV signals and High Dynamic Range (HDR) capabilities. Immersive and personalized audio is also emerging, with the ability to enhance the quality and variety of audio. -

It is clear that modern media and telecom users want increased choices in content and in services, and they want whatever options they choose to be available in a form that is fast, convenient and easy to use. Once users feel the satisfaction and power of having voice and video, audio and data packages at their fingertips, they tend to want more and more. -
Dtv Implementation: a Case Study of Angola, Indiana
DTV IMPLEMENTATION: A CASE STUDY OF ANGOLA, INDIANA Andrew Curtis Black A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of MASTER OF ARTS August 2014 Committee: Sandra Faulkner, Advisor Victoria Ekstrand Jim Foust Thomas Mascaro © 2014 Andrew Curtis Black All Rights Reserved iii ABSTRACT Sandra Faulkner, Advisor On June 12, 2011, the United States changed broadcast standards from analog to digital. This case study looked at Angola, Indiana, a rural community in Steuben County. The community saw a loss of television coverage after the transition. This study examined the literature that surrounded the digital television transition from the different stakeholders. Using as a framework law in action theory, the case study analyzed governmental documents, congressional hearings, and interviews with residents and broadcast professionals. It concluded that there was a lack of coverage, there is an underserved population, and there is a growing trend of consumers dropping cable and satellite service in the Angola area. iv Dedicated to Professor & Associate Dean Emeritus Arthur H. Black Dr. Jeffrey A. Black Coadyuvando El Presente, Formando El Porvenir v ACKNOWLEDGMENTS First and foremost, I would like to thank my family. To my parents whose endless love and support have surrounded my life. They believed, pushed, and provided for my success and loved, cared, and understood in my failures. I would like to thank my wife, Elizabeth, for putting up with me. The crazy hours, the extra jobs, the kitchen-less heat-less apartment, and all the sacrifices made so that I could pursue a dream. -
