The Advanced Television Systems Committee has been exploring automotive use cases for the ATSC 3.0 standard, applications that include robust broadcast updates for telematics and navigation, sensors for autonomous vehicles, and in-car infotainment systems, according to a new ATSC planning team report.
“Next-generation broadcasting powered by ATSC 3.0 paves the way for a broad range of automotive applications that will leverage the standard’s Internet Protocol backbone, robust mobile reception and one-to-many architecture for data and video services,” said ATSC President Madeleine Noland.
ATSC disclosed its automotive efforts in the just-published summary of a planning team update report presented last month to the ATSC Board of Directors. While ATSC 3.0 may be best known as a television standard, it enables a multitude of new applications of interest to leading automakers, according to Planning Team 5 Chairman Dr. Jong Kim, Senior Vice President, LG Electronics, and President, Zenith R&D Lab.
He explained that ATSC has been working with automotive OEMs and fleet owners to define and explore key vehicular use cases. They include: data delivery for infotainment, software/firmware updates and advanced emergency information, as well as network redundancy and resiliency for rural coverage, indoor garage penetration and available throughput when other networks experience congestion. More study is needed on other applications such as using the high power high tower broadcast infrastructure to augment or replace GPS or deliver precision time data.
Other ATSC 3.0 use cases related to intelligent transportation systems were identified, including software and firmware updates for “smart” road equipment and sensors; maps, telematics and emergency information for freight; and emergency information for first-responder vehicles, as outlined in the report.
The report also highlights various ATSC 3.0 automotive activities over the past year. Among them: ATSC co-hosted (with Pearl TV and WXYZ-TV) a workshop in Detroit, made presentations for members of the Intelligent Transportation Systems of America and participated in a seminar at the University of Michigan.
The planning team has “achieved our initial goal to introduce ATSC 3.0’s capabilities, especially mobile video and data delivery using the television broadcast transmission infrastructure, to major automakers and rental car fleets,” said Dr. Kim. Efforts are now under way to reschedule ATSC 3.0 field trials with leading automakers originally planned for spring 2020 but postponed due to the coronavirus pandemic, he added.
