Successful delivery of Next Gen TV using ATSC 3 and preserving the Traditional ATSC 1 requires cooperation between broadcasters to deliver a user experience that meets and exceeds today?s online content streaming but maintains compliance with the FCC obligations.
To build this out quickly this will require a flexible network strategy using Public and Private Network topologies that address the challenges of hardening of the required Synchronous SFN against malicious attacks both internal and external to guarantee the delivery of Emergency Alerts to the public during the time of Crisis. We will review different strategies in use today for Public and Private Networks used for South Korea ATSC 3, ATSC 1, DAB, DVB and ISDB-T systems.
Learning Objectives:
– Effective cost control of building a Regional Media Network between broadcasters, leveraging both public and private networks for live media delivery.
– How to simplify the legal issues of connectivity, SLA and Retrans Agreements through a Software Defined Network (SDN).
– Examples of recent outside attacks on terrestrial networks, with lessons learned from building out of the SFN and realistic ways to address the vulnerabilities.

ATSC 3.0, often referred to as “NEXTGEN TV,” is gaining traction and is now being broadcast in over 60 markets in the United States. There are many challenges for broadcasters to adopt this technology and this is especially a concern for Public Broadcasters who may not have a necessary simulcast partner in their markets to continue ATSC 1.0 transmissions while beginning ATSC 3.0 operations. This paper presents a potential roadmap for stations, with an emphasis on statewide networks, to deploy ATSC 3.0. Examples in this paper will focus on two PBS North Carolina broadcast facilities and one Iowa PBS broadcast facility, but the criteria used could easily be adapted for other stations.

When disasters strike, it is imperative that lines of communication remain open so that the public can receive important and potentially lifesaving updates from authorized authorities. For television and radio broadcasters this information has been provided by Emergency Alert System (EAS) announcements and through newscasts and weather alerts. Wireless Emergency Alerts (WEA) were developed to deliver similar announcements to the public via cellular networks if they are within the targeted area. But what happens if cellular service is compromised due to disaster? In 2017 the Federal Communications adopted a new, voluntary television broadcast standard developed by the Advanced Television Systems Committee (ATSC), a standard development organization. The new standard, ATSC 3.0 (also known as NEXTGEN TV), is built on a robust over-the-air broadcast platform and utilizes an Internet Protocol core.i Could ATSC 3.0 be a solution during widespread outages to deliver critical messages to mobile devices? This paper explores this issue and will describe a tested solution.

Last year, we presented a ATSC 3.0 backward compatible in-band backhaul system. In this paper we will present the field measurement results that support the viability of the in-band backhaul system implementation using full-duplex transmission. We further present a full duplex Inter-Tower Communication System ? a re-configurable wireless network for SFN broadcasting, in-band inter-tower communications, and IoT/datacasting applications, while backward compatible with the ATSC 3.0.
(1) SFN Broadcasting:
Improve service quality for mobile, handheld, and indoor receptions;
Allow new services: IoT, connected car, datacasting;
One-to-many timely services for large rural areas for traffic map update, weather conditions, emergency warning.
(2) In-band Distribution for SFN
Eliminate studio-to-tower link spectrum requirement;
Reduce broadcast operating costs;
Spectrum sharing and re-use.
(3) Inter-Tower Wireless Network
Scalable & reconfigurable network embedded in a broadcast system;
Broadcast network cue & control that do not rely on other telecom infrastructure ? surviving emergency and nature disaster;
Backhaul data services among towers: IP-based IoT, and wide-area datacasting;
Each tower can broadcast localized content in its coverage area (TDM/LDM);
Inter-Tower Network can work under SFN, OCR, or Multi-Frequency Network environments;
Full-Duplex Transmission: Transmitting and receiving on the same frequency ? improving spectrum efficiency;
Dynamic Spectrum Re-Use and Sharing + LDM: Converging Broadcast and Wireless Broadband Services.
