The 2023 NAB Show exhibits and sessions demonstrated the future of ATSC 3.0 can extend beyond traditional over-the-air TV broadcasting. I’ll focus on three ATSC 3.0 innovations: Use of ATSC 3.0 to provide precision time and positioning services; efficient data transmission for radio over ATSC 3.0; and sharing an ATSC 3.0 channel with a 5G signal.
Broadcast Positioning System
The topic of using ATSC 3.0 as a backup for GPS was discussed in the session “Delivering Traceable Reference Time for ATSC 3.0-based Broadcast Positioning System (BPS),” by Patrick Diamond of Diamond Consulting and co-authored with Tariq Mondal and Robert Weller from NAB and Andrew Hansen at Volpe Center.
