Video: ATSC 3.0 OTA Meets OTT

ASTC 3.0 has taken the bold move to merge RF-delivered services with internet-delivered services. Branded as ‘NextGen TV’, the idea that viewers shouldn’t need to know which path their service comes by is a welcome shift from the days of needing to select the right input on your TV. We’ve covered here before the technical details of ATSC 3.0 but today we’re looking the practical side of delivering such a service.

In this Streaming Media video, Nadine Krefetz hosts a conversation with Madeleine Noland from ASTC, Todd Achilles from Evoca TV, Jim DeChant from News Press & Gazette Broadcasting aswell as Sassan Pejhan. They start by highlighting that one reason ATSC 3.0 was developed over the previous ATSC 1.0 is that it opens up the possibility of delivering HDR and/or UHD along with Dolby Atomos.

 

 

Given ATSC 3.0 uses the same MPEG DASH delivery that online streaming services use, one question is why use ATSC 3.0 at all. The benefit of broadcast medium is in the name. There’s extreme efficiency in reaching thousands or millions of people with one transmitter which ATSC 3.0 uses to its advantage. In ASTC 3.0’s case, transmitters typically reach 40 miles. The panel discusses the way in which you can split up your bandwidth to deliver different services with different levels of robustness. Doing this means you can have a service that targets reception on mobile devices whilst keeping a high bandwidth, more delicately modulated channel for your main service intended for delivery to the home.

Not unlike the existing technologies used by satellite and cable providers such as SkyQ in the UK, an internet connection can be used to deliver user-specific adverts which is an important monetisation option that is needed to keep in step with the streaming services that it can work in tandem with. Madeleine explains that ATSC has created APIs for apps to query TV-specific functions like whether it’s on or off but these are the only ways in which app development for ATSC 3.0 differs from other web-based app development.

Finishing up the conversation, the panel discusses the similarities and differences to 5G.

Video: Understanding the World of Ad Tech

Advertising has been the mainstay of TV for many years. Like it or loathe it, ad-support VoD (AVoD) delivers free to watch services that open up content to a much wider range of people than otherwise possible just like ad-supported broadcast TV. Even people who can afford subscriptions have a limit to the number of services they will subscribe to. Having an AVoD offering means you can draw people in and if you also have SVoD, there’s a path to convince them to sign up.

To look at where ad tech is today and what problems still exist, Streaming Media contributing editor Nadine Krefetz has brought together Byron Saltysiak from WarnerMedia, Verizon Media’s Roy Firestone, CBS Interactive’s Jarred Wilichinksy and Newsy’s Tony Brown to share their daily experience of working with OTT ad tech.

 

 

Nadine is quick to ask the panel what they feel the weakest link is in ad tech. ‘Scaling up’ answered Jarred who’s seen from massive events how quickly parts of the ad ecosystem fail when millions of people need an ad break at the same time. Bryon adds that with the demise of flash came the loss of an abstraction layer. Now, each platform has to be targetted directly leading to a lot of complexity. Previously, as long as you got flash right, it would work on all platforms. Lastly, redundancy came up as a weakness. Linked to Jarred’s point about the inability to scale easily, the panel’s consensus is they are far off broadcast’s five-nines uptime targets. In some ways, this is to be expected as IT is a more fragmented, faster-moving market than consumer TVs making it all the harder to keep up and match the changing patterns.

A number of parts of the conversation centred around ad tech as an ecosystem. This is a benefit and a drawback. Working in an ecosystem means that as much as the streaming provider wants to invest in bolstering their own service to make it able to cope with millions upon millions of requests, they simply can’t control what the rest of the ecosystem does and if 2 million people all go for a break at once, it doesn’t take much for an ad provider’s servers to collapse under the weight. On the other hand, points out Byron, what is a drawback is also a strength whereby streaming has the advantage of scale which broadcasters don’t. Roy’s service delivered one hundred thousand matches last year. Byron asks how many linear channels you’d need to cover that many.

Speed is a problem given that the ad auction needs to happen in the twenty seconds or so leading up to the ad being shown to the viewer. With so many players, things can go wrong starting off simply with slow responses to requests. But also with ad lengths. Ad breaks are built around 15 seconds segments so it’s difficult when companies want 6 or 11 seconds and it’s particularly bad when five 6-second ads are scheduled for a break: “no-one wants to see that.”

Jarred laments that despite the standards and guidelines available that “it’s still the wild west” when it comes to ad quality and loudness where viewers are the ones bearing the brunt of these mismatched practices.

Nadine asks about privacy regulations that are increasingly reducing the access advertisers have to viewer data. Byron points out that they do in some way need a way to identify a user such that they avoid showing them the same ad all the time. It turns out that registered/subscribed users can be tracked under some regulations so there’s a big push to have people sign up.

Other questions covered by the panel include QA processes, the need for more automation in QA, how to go about starting your own service, dealing with Roku boxes and how to deal with AVoD downloaded files which, when brought online, need to update the ad servers about which ads were watched.

Video: OTT Workflow Integration Best Practices

Streaming can seem deceptively simple and a simple HLS workflow can be, but to deliver a monetised service to a wide range of devices, with a mix of live and on-demand assets, with advertising and DRM where needed is far from trivial. In this video, we hear from several companies on how they manage the complexity which allows their service to thrive.

Nadine Krefetz from streaming media asks the questions as we hear from Sinclair, Eyevinn Technology, fuboTV, FandangoNOW and Verizon Media. Firstly they introduce us to their services and the types of workflows that they are maintaining day in, day out.

Companies like Sinclair are frequently adding new channels through market acquisitions. Those companies that don’t grow through acquisition will, similarly, find themselves looking at their own legacy workflows as they look to modernise and improve their offering. Our panel gives their thoughts on tackling this situation. Magnus Svensson and Michael E. Bouchard both talk about having a blueprint, in essence, a generic workflow which contains all the functional blocks needed for a streaming service. You can then map the old and new workflows to the blueprint and plan migration and integration points around that.

The panel covers questions about how smaller services can address Roku and Amazon Fire devices, what to ask when launching a new service and which parts of their services would they never want to buy in or outsource.

Ad insertion is a topic which is essential and complex. Server-Side Ad Insertion (SSAI) is seen as an essential technology for many services as it provides protection against adblockers and can offer more tight management of how and when viewers see ads. But the panel has seen that ad revenues are lower for SSAI since there are fewer analytics data points returned although VAST 4.0 is addressing this problem. This has led to one of the panel members going back to client-side ads for some of their workflows simply due to revenue. Magnus Svensson points out that preparation is key for advertising: Ensuring all adverts are in the correct formats and have the right markers, having slides ready and pre-loading to reduce peaks during live transmissions.

The panel closes looking at their biggest challenges, often in adapting to the pandemic, and the ever-evolving landscape of transport formats.

Video: Harness SSAI’s Superpowers

Server-side Ad Insertion (SSAI) is a great option for streaming services delivering video to a wide variety of devices and for those who need to avoid ad blockers. Whilst ad insertion can happen in the player, this mechanism can be interfered with allowing users to avoid ads. Whilst client-side ad insertion can much more easily create a unique stream for each client, dynamic SSAI can now do the same with a better user experience.

This panel from the OTT Leadership Summit at Streaming Media West 2019 brings together Disney, WarnerMerdia and Crunchyroll to share their experiences with SSAI. They discuss beaconing, ad standards, scaling, SCTE and more.

Beaconing goes hand in hand with ad playback providing metrics on what happened. When you perform certain actions, the player will reach out to a URL. This can be used to indicate such things as users skipping or pausing a video. The beacon information can then be used to verify how much of which ads were seen by whom and charge advertisers accordingly.

The panel moves on to discussing scaling using live sports as an example and cover questions to ask vendors to ensure you and they are ready for maximum scale. Bandwidth, is declared the biggest challenge, but a less obvious problem is that your upstream ad providers can’t always scale well. If you rely on calls from your server to others, then it’s vital to understand their scaling capacity and strategy. They discuss issues with losing beacons when operating at scale and the need for detailed logging and debugging in order to spot errors and reconcile the results.

Some time is next spent on VPAID and VAST 4 which are both messaging specifications to allow ad servers to tell applications which ads to play. The panel discusses the pros and cons in their use for SSAI where the stitcher needs to reach out to and ad server in real time to find out which ads to play.

At the end of the discussion, the panel takes questions from the floor but not before discussing SCTE Markers and ‘content conditioning’ which surrounds taking care of your source videos and encoder such that the two assets fit together properly at I-frame boundaries.
