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.

Xperi’s AutoStage is a hybrid (over-the-air plus internet connectivity) radio platform that brings tremendous value to both broadcasters and listeners. The first automaker to sell vehicles with an AutoStage-based infotainment system was Mercedes, introducing this technology with their S-class vehicles in late 2020.

After attending a number of state broadcast association events, NAB CTO Sam Matheny sees a pattern and it is one that highlights a real challenge for our industry. “Where are we going to find the next generation of broadcast engineers?” is a common question at every one of these gatherings.
