Switching to ATSC 3.0: A Primer on New Broadcast Standards

A lot has changed in the television industry since the current broadcast standard, ATSC 1.0, was introduced in the ’90s. Remember linear editing? Remember videotape? Now even the standard 4:3 ratio feels like ancient history. You know it’s time for the next-generation broadcast standard, but you may be wondering how ATSC 3.0 will change what you deliver to your audience and how it will impact your operations. Harmonic covered insights and answers to these very questions during a recent Harmonic TechTalk Webinar: Make Room for ATSC 3.0.

A revolutionary advancement
Dolby’s Professional Partners are leading the way, already incorporating the advanced technologies behind the new standard, like Dolby® AC-4 and High-Efficiency Video Coding (HEVC), into their products. They are already experiencing how ATSC 3.0 will revolutionize how content is delivered to viewers, whether in their living room with a flat-screen HDTV or on the go with a mobile phone. The new standard isn’t just designed to catch up with the last 20 years of technological advances; it’s designed to propel broadcast television into the future, and allow you to adapt and evolve with the technological breakthroughs to come.

ATSC 3.0 is up to 50 percent more efficient in video and audio compression, which means you can deliver Ultra HD resolution with a wide color gamut, high dynamic range, a high frame rate, and immersive Dolby® Atmos audio that puts the viewer in the middle of the action. Further, there’s enough bandwidth to offer customizable options like enhanced dialog, director commentary or optional audio tracks, like a viewer’s favorite home team announcer for a sports team.

The nuts and bolts
But how does this new standard work? How will HEVC and Dolby AC-4 improve efficiency? And what does this new codec mean for your workflow?

Listen to the webinar—produced by Harmonic in conjunction with Dolby (broadcast on April 12, 2017) for more about ATSC 3.0 and the impact that Dolby AC-4 has on the standard.
