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.
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. [...]
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 [...]
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 [...]
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.
AWARN Kicks off Regional Roundtables to “Reboot” the TV Broadcaster-Public Safety Relationship with ATSC 3.0
With its local broadcasting partners, the AWARN Alliance is convening a series of roundtable discussions between local TV stations and local emergency managers – the people who issue emergency alerts. The goal is to lay the groundwork for the voluntary use of NEXTGEN TV Advanced Emergency Information (AEI) and “reboot” the historic relationship between broadcasting and public safety.
NAB is a charter member of the Ultra HD Forum, an organization devoted to aiding the creation and distribution of Ultra HD content. NAB CTO Sam Matheny believes that Ultra HD is really about better storytelling and bringing the state of the art in terms of picture and sound quality. While NAB's participation has much to do with broadcast over the air (OTA) delivery of Ultra HD content, our members are also delivering content via cable, satellite and over the top (OTT).
