A previous blog in this series noted that ATSC was engaged in the process of adapting the ATSC-1 DTV standard documentation so that it was compliant with MPEG-4 (also known as AVC) implementations that are known to work in the marketplace with legacy receivers. That work was completed with the approval of A/53 Part3: 2013 Amendment No. 1 “AVC Signal Transport” on February 15, 2023.

The annual CES (formerly known as the Consumer Electronics Show) offers an amazing array of new technologies and 2023 was no exception. The new West Hall of the Las Vegas Convention Center is where automotive technology was center stage, and where Xperi was demonstrating an exciting new aspect of their DTS AutoStage hybrid (over-the-air plus [...]

Part 1 and Part 2 of this three-part series showed how channel sharing can be used to make RF channels available for ATSC 3.0 services and how MPEG-4 compression can assist in that goal. However, the theoretical modeling used in the examples is based only on optimizing spectrum use, a noble goal which should [...]

In Part 1 of this series, the spectrum efficiency and advantages of using MPEG-4 compression for DTV transmission were explored in the context of the transition to ATSC 3.0 broadcasting. Using the guidelines from Part 1 for a theoretical example, consider a market with six TV stations, each with one HD signal (the primary [...]

Television broadcast service based on ATSC 3.0 technology, or NEXTGEN TV, is better than ATSC-1 in virtually all respects. But the ATSC 3.0 transition is challenging because, unlike the original DTV transition, broadcasters do not have access to additional unused RF channels on which to transmit ATSC 3.0 signals while also simulcasting their ATSC-1 [...]

We wanted to know what technologists in our industry are excited about and expect or hope to see in 2023, so we asked the NAB Technology staff and a few other luminaries in the industry if they had anything to share. They did. This compilation of predictions is our way to wrap up 2022 by looking forward to 2023.
