  • ATSC 3.0 and Wireless Emergency Alerting - a Great Match - $15

    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.

  • Dynamic Ad Insertion through [Data Distribution as a Service System (DDaaS) – MMT Protocol – Broadcast Application] without Internet connection - $15

    Over-the-Air (OTA) advertising lacks features provided by its Over-the-Top (OTT) counterpart due to the one-way nature of OTA advertising. Introducing the Advanced Television Systems Committee (ATSC) 3.0 standard and its approach to broadcasting information utilizing the Internet Protocol (IP) narrows the gap between the two environments. While there are similarities in the mechanisms to create regionally addressable advertisements through OTT and OTA (utilizing the ATSC 3.0 standard), they are not identical, primarily due to the latter being a one-way broadcasting system. This paper introduces two potential solutions to provide targeted advertising through the timely insertion of advertisements into live TV programs. We also review a Data Distribution as a Service (DDaaS) platform and the ATSC 3.0 MPEG Media Transport (MMT) protocol, which are integral to making these solutions feasible.

  • Translators for ATSC 3.0 - $15

    There are over 3000 TV translators presently licensed in the US. Translators, by definition, rebroadcast the signals of one or more originating stations on a different channel. As the ATSC 3.0 transition rolls on, these translator stations are faced with the need to retransmit the programs and advanced services that may be available from originating stations that have converted to 3.0. An ATSC 1.0 translator is comparatively a simple product – it typically consists of an 8-VSB receiver/demodulator, then an 8-VSB modulator/exciter, often with the ability to modify the PSIP information to be appropriate for the translator. An ATSC 3.0 translator brings a much higher level of complexity. Many of the functions of a broadcast gateway/scheduler must be included with the 3.0 translator, as it provides parameter information and baseband signal formatting for the exciter.  While some translators use off-air RF input from an antenna, others use some terrestrial links (fiber, microwave, etc.) to deliver the program signals to the translator. These sources bring additional variations to the equipment required. Beyond that, a translator may choose to rebroadcast the program signals from multiple originating stations, so some multiplexing and signal grooming may be needed. Furthermore, a translator station may wish to continue to broadcast in the ATSC 1.0 format, while its originating station converts to ATSC 3.0, which creates other challenges. And there remains the issue of modifying the signaling information to be appropriate for the translator’s broadcast. This paper will examine these different operating situations and explain what is needed to afford the broadcaster the ability to take advantage of ATSC 3.0’s capabilities, while providing the required services to their viewers.
