ATSC 3.0 is the future of over-the-air TV, combining existing antenna technologies with internet-powered tools to deliver the next generation of digital broadcasting.
Wondering what happened to ATSC 2.0? Yeah, good question. It was basically outdated before it had the chance to launch. All of the changes that were added in ATSC 2.0 have been integrated into ATSC 3.0. ATSC 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. Audio quality is increased as well. 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.
More than TVs 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. 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. However, there’s still no word on when we’ll actually be able to buy them .
The possibilities run the gamut, including in-car advertising, over-the-air software updates, mapping, and driverless vehicle automation — ATSC 3.0 could even act as a backup or replacement for GPS technology. It’s all in the early stages as carmakers and companies that own large vehicle fleets explore the options, but it’s clear from these discussions that ATSC 3.0 can be much more than just a way to get high-quality TV shows into your home.
Still, the possibilities present with IP-based datacasting are intriguing. Almost 20 years ago, Microsoft unveiled a system called MSN Direct, which used FM frequencies to send small amounts of data to devices like Spot-equipped smartwatches. News headlines, sports scores, weather, and even personalized information like MSN Messenger texts and calendar reminders were all part of the platform.
One other possible downside, depending on how you look at it, is that the same geotargeting that allows for advanced emergency alerts can also be used for targeted ads. This means the ads you see on TV will start to more closely resemble what you see online. We’re not yet sure how this will play out for major advertising events like the Superbowl, but on the whole, if targeted ads don’t bother you on the web, they shouldn’t bother you on your TV.
