In fact, in 2021, Sinclair Broadcast Group teamed with South Korea’s SK Telecom to create CAST.ERA, a Virginia-based broadcast solution that promises impressive picture upscaling, low-latency transmissions, and more. There’s even talk of ATSC 3.0 being integrated with existing 5G cellular networks. However, there’s still no word on when we’ll actually be able to buy them (or if they’re any good). One Media 3.0, a subsidiary of Sinclair Broadcast Group - big backers of the ATSC 3.0 standard - introduced mobile receiver chips in January 2019 and even created an Android prototype phone that uses them. Given that more and more people now use their phones as their primary video devices, it’s no surprise that ASTC 3.0 has been designed with mobile in mind. Advanced emergency alerts are also part of the standard, including better geotargeting, which means advancements like the ability to broadcast evacuation routes to areas that need that information.Īdditionally, ATSC 3.0 utilizes Orthogonal Frequency Division Multiplex (OFDM) as part of its core encoding, compared to the 8VSB encoding used for ATSC 1.0, which means that the transmission and reception of ATSC 3.0 content should encounter far less interference than older 1.0 broadcasts. In addition to the picture and audio improvements, ATSC 3.0 also makes it possible to watch broadcast video on mobile devices like phones and tablets, as well as in cars. While ATSC 1.0 uses Dolby AC-3 - an audio format that is limited to 5.1 channel surround sound - ATSC 3.0 uses the newer Dolby AC-4 for broadcasts of up to 7.1.4 channel audio, and it supports object-based sound formats like Dolby Atmos.Ĭleverly, AC-4 can adapt to your gear, so if your TV or A/V receiver can support 5.1.2 Dolby Atmos, and it’s available on the movie you’re watching, that’s what you’ll get - but lesser components still get a version they can reproduce, too. Over time and through upgrades, it will be able to adopt newer codecs like the recently finalized H.266 VVC codec, which is the leading candidate to usher in 8K when that time comes.ĪTSC 3.0 also includes benefits for reception, meaning you should be able to receive more channels of higher quality without the need for a large antenna. Right now, ATSC 3.0 uses the H.265 HEVC codec for video delivery because of its efficiency gains over the much older H.262 MPEG-2 codec used in ATSC 1.0.ĪTSC 3.0 isn’t married to a single video format. Other picture quality upgrades, including high dynamic range (HDR), wide color gamut (WCG), and high frame rate (HFR) are all part of the new provision. While the current ATSC 1.0 standard caps out at 1080i, the new standard allows for 4K UHD broadcasts. The first major benefit is picture quality. What are the benefits? Dan Baker/Digital Trends All of the changes that were added in ATSC 2.0 have been integrated into ATSC 3.0. It was basically outdated before it had the chance to launch. Wondering what happened to ATSC 2.0? Yeah, good question. By leveraging the same underlying protocols as the internet, ATSC 3.0 makes these experiences possible. The switch to digital that ATSC 1.0 delivered helped to improve picture and sound quality, but it also laid the groundwork for a vast new world of broadcast content and interactivity. ATSC 3.0 is the latest version of the Advanced Television Systems Committee standards, defining how exactly television signals are broadcast and interpreted. OTA TV signals currently use version 1.0 of the ATSC standards, which were introduced all the way back in 1996, initiating the switch from analog to digital TV that was finalized in the U.S.
