Video: CEDIA Talk: ATSC 3.0 is HERE – Why It Matters to You


That last in the current series of ATSC 3.0 posts. This one is a light, but useful talk which aims to introduce people to ATSC 3.0 calling out the features and differences.

Michael, showing off his colour bars jacket, explains how ATSC 3.0 came about and how ATSC 2.0 never came to pass and ‘is on a witness protection program’. He then explains the differences between ATSC 1.0 and 3.0, discussing the fact its IP based and capable of UHD and HDR amongst other things.

The important question is why is it better and we see the modulation scheme is an improvement (note Michael says ATSC 3.0 is based on QAM; it actually based on OFDM.)

The talk finishes talking about what ATSC 3.0 isn’t and implementation details and the frequency repack which is happening in the US.

Video: Next Generation Broadcast Platform – ATSC 3.0

Continuing our look at ATSC 3.0, our fifth talk straddles technical detail and basic business cases. We’ve seen talks on implementation experience such as in Chicago and Phoenix and now we look at receiving the data in open source.

We’ve covered before the importance of ATSC 3.0 in the North American markets and the others that are adopting it. Jason Justman from Sinclair Digital states the business cases and reasons to push for it despite it being incompatible with previous generations. He then discusses what Software Defined Radio is and how it fits in to the puzzle. Covering the early state of this technology.

With a brief overview of the RF side of ATSC 3.0 which itself is a leap forward, Jason explains how the video layer benefits. Relying on ISO BMMFF, Jason introduces MMT (MPEG Media Transport) explaining what it is and why it’s used for ATSC 3.0.

The next section of the talk showcases libatsc3 whose goal is to open up ATSC 3.0 to talented Software Engineers and is open source which Jason demos. The library allows for live decoding of ATSC 3.0 including MMT material.

Finishing his talk with a Q&A including SCTE 34 and an interesting comparison between DVB-T2 and ATSC 3.0 makes this a very useful talk to fill in technical gaps that no other ATSC 3.0 talk covers.

Video: Recent Experiences with ATSC 3.0 from Seoul to Phoenix

This talk is part of a series of talks on ATSC 3.0 we’re featuring here on The Broadcast Knowledge. ATSC 3.0 is a big change in terrestrial television transmission because even over the air, the signal is IP.

In this talk, Joe Seccia from GatesAir, a company famed for its transmission systems, talks us through where the US (and Seoul) is on its way to deploying this technology.

With major US broadcasters having pledged to be on air with ATSC 3.0 by the end of 2020, trials are turning in to deployments and this is a report back on what’s been going on.

Joe covers the history of previous tests and trials before taking us through the architecture of a typical system. After explaining the significance of the move to IP, Joe also covers other improvements such as using OFDM modulation and thus being able to use a single frequency network (SFN). This combination of technologies improves reception and coverage over the 8VSB transmissions which went before it.

We also hear about the difference between home and broadcast gateways in the system as well as the Early Alert System Augmentation features which allow a broadcaster to ‘wake up’ TVs and other devices when disasters strike or are predicted.

Video: Everything You Wanted to Know About ATSC 3.0

ATSC 3.0 is the next sea change in North American broadcasting, shared with South Korea, Mexico and other locations. Depending on your viewpoint, this could be as fundamental as the move to digital lockstep with the move to HD programming all those years ago.

ATSC 3.0 takes terrestrial broadcasting in to the IP world meaning everything transmitted over the air is done over IP and it brings with it the ability to split the bandwidth into separate pipes.

Here, Dr. Richard Chernock presents a detailed description of the available features within ATSC. He explains the new constellations and modulation properties delving into the ability to split your transmission bandwidth into separate ‘pipes’. These pipes can have different modulation parameters, robustness etc. The switch from 8VSB to OFDM allows for Single Frequency Networks which can actually help reception (due to guard intervals).

Additionally, the standard supports HEVC and scalable video (SHVC) whereby a single UHD encode can be sent which has an HD base-layer which can be decoded by every decoder plus an ‘enhancement layer’ which can be optionally decoded to produce a full UHD output for those decoders/displays which an support it.

With the move to IP, there is a blurring of broadcast and broadband. This can be used to deliver extra audios via broadband to be played with the main video and can be used as a return path to the broadcaster which can help with interactivity and audience measurement.

Dr. Chernock covers HDR, better pixels and Next Generation Audio as well as Emergency Alerts functionality improvements and accessibility features.

Video: Power Talks – ATSC 3.0

ATSC 3.0 is the major next step in broadcasting for the US, South Korea and other countries and is a major update to the ATSC standard in so many way that getting across it all is not trivial. All terrestrial broadcasting in the US are done with ATSC as opposed to many other places, including Europe, which use DVB.

ATSC 3.0 brings in OFDM modulation which is a tried and tested technology also used in DVB. But the biggest change in the standard is that all of the transport within ATSC is IP. Broadcasters now, using broadband as a return path, have two-way communication with their viewers allowing transfer of data as well as media.

In this talk from Imagine Communications, we talk a look into the standard which, as is common nowadays, is a suite of standards. These standards cover Early Alerts, immersive audio, DRM, return paths and more. We then have a look at the system architecture of the ATSC 3.0 broadcast deployed in Phoenix.

South Korea has been pushing forward ATSC 3.0 and Chet Dagit looks at what they have been doing and how they’ve created high quality UHD channels to the consumer. He then looks at what the US can learn from this work but also DVB deployments in Europe.

Finally, Yuval Fisher looks at how the data and granularity available in ATSC 3.0 allows for more targeted ads and how you would manage both internally and harnessing it for ad campaigns.

Webinar: ATSC 3.0 Hybrid Services in Action, with Chicago 3.0

Tuesday March 12th, 2019. 8am PT / 11 ET / 16:00 GMT

ATSC 3.0 is a big change from previous ATSC and DVB transmission standards due to its ability to mix IP with traditional broadcast signals. By merging the best of IP with the best of DTH transmission, ATSC 3.0 enables new business models and helps broadcasters bring their current offerings up to date.

But what about the reality? Weigel Broadcast joined forces with top-tier companies to build out the station, including: Rohde Schwarz, Harmonic Inc., Triveni Digital, Enensys, Alive Telecommunications, and Sony. Each partner contributed essential equipment and resources for the sign-on of the ATSC 3.0 roll-out dubbed ‘Chicago 3.0.’

In this webinar, Harmonic’s Jean Macher is joined by Kyle Walker, VP technology at Weigel broadcast to take us through why the native IP transport is such a benefit and how they managed the experience across all viewers.

The webinar covers what was deployed, how it worked and the results. Plus they’ll also cover the principles of ATSC 3.0 services and the use-cases involved in Chicago 3.0.
