How Dynamic Ad Insertion Works

Kevin Reynolds · October 16, 2018 ·

What is dynamic ad insertion? How are ads delivered to OTT/CTV devices? Can linear, VOD and SVOD have different ad loads? Can linear advertising be geo-targeted from a centralized management infrastructure? We’ll attempt to answer these questions, at a high level, in this article.

After finally cutting the cord, we started to notice differences in how ads are being served in the OTT/CTV ecosystem. Yes, sometimes we see the same ad over and over, but in other cases there are a variety of ads, including retargeting ads. The experience reminded us more of online advertising than traditional linear television advertising. Researching the technology to understand how these ads are delivered, we found that the enabling technology for cross platform, targeted, audience based video advertising is Dynamic Ad Insertion (DAI). What follows is a description of one method for accomplishing DAI.

Just a few years ago, the lack of DAI technology was the roadblock to audience based targeting. Fast forward to today and the technology is not only available for online video, it is in use across platforms for linear broadcast, VOD, mobile and OTT/CTV, enabling targeting by platform, device, audience and geography.

To understand DAI, let’s examine “Blackout” programming in the linear television ecosystem. Broadcasters must occasionally pre-empt programming in a local market to comply with contractual agreements. Traditionally, this was accomplished by “splicing” the analog video stream to insert the alternate content. However, the level of effort and broadcast hardware configuration required by this technique limited its use for advertising insertions.

With the advent of Adaptive Bitrate Streaming (ABR) for online video, a digital, software based approach to alternate content insertion has evolved. ABR provides a method for delivering multiple video quality levels within a video stream. Video data within the stream is separated into fragments, and each fragment contains blocks containing payloads at different bit rates. This allows a client device or video player to choose the appropriate bit rate for the performance level of the connection at a given point in time. The video client determines the connection performance level by measuring the time the blocks take to load.

In order to manage these fragments of content, a manifest (or playlist), is sent alongside the stream. The manifest contains URLs (pointers) to the video files contained within the stream. In addition to identifying the bit rates available, the manifest contains metadata which identifies the type of content (programming, advertising, PSA, etc.) being delivered to client player. To enable DAI, an Alternate Content Decision Service (ACDS) parses this metadata, and provides an alternative manifest which identifies the bespoke advertising, blackout, or geographic content to playout. In this way, targeted advertising can be delivered to client browsers and devices. Note that this also can also allow for centralized management of both national and regional programming.

A placement opportunity information service (POIS) can be used to host metadata about the location and rights associated with alternate content opportunities (ADCS) within linear and on-demand video. API connections between demand side platforms (DSP) and POIS can facilitate programmatic workflows for advertising placements.

Connected devices that receive programming via unicast transmission (i.e. mobile phones), can return data on a per device basis for tracking and attribution. For QAM, ATSC and IP connected devices, the manifest contains data regarding playout of stream content. ATSC 3.0 promises to provide back channel data via the internet for over the air statistics.

An associated technology innovation is HTTP to UDP conversion. Traditional broadcast infrastructure uses Quadrature Amplitude Modulation (QAM) over cable or fiber distribution networks and ATSC over the air. Typically, OTT/CTV infrastructure uses the HTTP protocol over IP to deliver video via DASH or HLS. Therefore, two parallel sets of infrastructure have been required to fulfill distribution across devices. HTTP to UDP conversion enables replacement of the analog, on premise infrastructure used for linear and VOD with the cross platform video ad server and CDN technology used for digital platforms. This eliminates the costly legacy equipment and maintenance and allows for a common architecture across platforms. Additionally, the CDN enables and supports “Cloud DVR” functionality for client devices and browsers.

These technologies stack up to provide an “end to end” ecosystem for targeted, programmatic video advertising, delivered across platforms, with tracking and attribution pointers embedded within the content. As broadcasters, MVPDs, service providers, advertisers and agencies embrace these platforms and toolsets, the vision of “the right message, at the right time, to an interested consumer” will become table stakes for advertising in the medium with the highest mass reach of all: Television.

Cordless

Kevin Reynolds · September 13, 2018 ·

So, we finally “cut the cord”. We had the full MVPD package with HBO, Showtime, STARZ, you name it we had it. All because I am addicted to NFL Redzone during fantasy football season and the provider (FIOS) only includes it with the premium package. Then one late summer morning we got “the letter”, informing us that HBO and Showtime were being removed from our package, and if we wanted to continue using them we could do so at an additional fee. Coincidentally, this communication came just days after the AT&T/Time Warner deal was approved.

I was livid. This was the final straw.

So, I called the provider to discuss the situation, and after two conversations, resulting in two different price quotes that increased my costs by 25% and 40% respectively, I told them: “Terminate my service. Tell me where to dump your equipment.”

I had done some research on OTT/CTV (same thing) and decided that Direct TV Now looked like the best fit. They were giving away an Apple TV if you signed up for 3 months. I already had a Roku box and a first gen Apple TV so I was all set. Or so I thought.

I’d watched Netflix on my Roku devices and had a decent experience, so I was not prepared for the drama of using OTT only… whoa. One word: buffering…

My first reaction was “the #&@%$$ MVPD is throttling the connection! That sucks!” After I calmed down, I actually paid attention to the modal message on the screen: “your network connection is underperforming….” Oh, maybe it’s the WiFi. One quick Target run later (lucky for me there is one literally around the corner) and I had a Netgear WiFi extender setup. Better, but still occasional buffering.

Because I have both a Roku and Apple TV, I switched back and forth between them to see if there was any performance difference. Negligible. But the user experience on the Apple TV, as you might expect, is vastly superior. Love that box. Interestingly, Netflix performs noticeably better than Direct TV Now on either device. I guess the death of net neutrality is showing its effects…

What about the ads? (after all this is the Advertising Perspectives blog…). Well, it’s interesting. Direct TV Now has a “Cloud DVR” feature. You can browse content by network and choose from a selection of on demand content. From this interface you can also record series. The “recorded” content works just like a hardware DVR. You can rewind and fast forward (skipping commercials). However, after a while, I found there was no need for me to record my favorite shows because they were (mostly) available on demand anyway.

On the flip side, live programming cannot be fast forwarded. You. Have. To. Watch. Commercials. All of them. Interestingly, everytime you switch to a different channel a new ad pod starts before the content plays.

So after about two months of OTT only I’ve come to these conclusions:

  1. The OTT user experience needs improvement to be on par with traditional MVPD products.
  2. Ethernet connections to the OTT/CTV hardware may be required for the best performance.
  3. My iPhone or iPad on AirPlay to the Apple TV actually works more reliably than the Apple TV or Roku on WiFi.
  4. You will see more ads.
  5. The ad targeting is interesting, and sometimes uncannily accurate. I saw different ad loads, on the same content, depending on the device.
  6. Unbelievably, there are empty ad pods, even on premium networks (ESPN Sunday Night Football… seriously?).
  7. Access to my entire content catalog across all my devices is awesome.
  8. Apple TV rocks.
  9. 1990’s era MTV reality shows are a hoot.
  10. I miss channel numbers.

This experience has left us fascinated with OTT ad tech. Stay tuned for more articles about it here at Advertising Perspectives.

 

 

Ad Exchanges and Real Time Bidding Update

Kevin Reynolds · December 6, 2014 ·

So it’s been over four years since we first posted “Are Ad Exchanges and RTB the Next Big Thing?“. We are amazed that the article is still being referenced as a resource for this topic. Let’s take a look and see what’s developed since 2010.

Real Time Bidding (RTB), is now often associated with “long tail” remnant inventory and being risky in terms of transparency around placement of impressions. Buyers cannot always determine exactly what site their ads run on. Publishers have often referred to the technology as “Race to the Bottom” as automated auctions drive CPM’s lower.

Now for the good news. The technology developed for automated auctioning of inventory has been re-branded as “Programmatic”. Programmatic is as buzz worthy in 2014 as RTB was in 2010 and has the potential to be even more influential. Here’s why:

  • Data: The technology stack enables the ability to target audiences in real time based on first party (publisher or marketer proprietary), second party (syndicated) and third party (aggregated) data. This technology has not only driven digital marketing growth rates, it will likely revolutionize the linear broadcast, cable television and on demand ecosystems as well. Television advertising is shifting from targeting based on the demographics of the show to targeting specific audiences based on data. Sound familiar?
  • Workflow productivity: Traditional digital buying revolved around the same workflow as traditional media: humans negotiating the terms of an insertion order. That means phone calls, emails and lots of excel. Top talent coming out of college, often with student loans to pay off, are not flocking to media agencies to do low paid grunt work. Conversely, top engineering talent that once headed to the financial services industry to build trading desks are now building Demand Side Platforms (DSP), Supply Side Platforms (SSP) and Data Management Platforms (DSP).
  • Removing the auction elements of the stack and replacing them with a means to allow publishers to set prices, establish guarantees on placement and leverage premium inventory, enables targeted marketing at scale with benefits to publishers, agencies and marketers alike.
  • These exchanges can be public like RTB, open to all marketers, or private, where publishers can control who has access to the inventory and at what price.

Note the reference to “marketers” vs. “advertisers”. The technology has evolved far beyond just buying and displaying ads. With rich data integration, marketers have converted the “Marketing Funnel” into the “Consumer Journey”. They can put the right message to each interested consumer at he right place at the right time. Awesome, right?

Not so fast kemosabe. Challenges remain:

  • The ecosystem is fragmented: Venture capital and the desire for profits has fueled literally hundreds of start ups and not all of them will survive. There are so many technology vendors and inventory sources in the space that marketing campaigns at scale are difficult to manage. There is a wave of consolidation happening and this will likely accelerate.
  • Lack of transparency around price and placement: Agencies and exchanges profit by being principals in transactions, often not revealing the prices paid for the inventory. Marketers are starting to push back, in some cases bringing the technology in house. Marketers are also concerned with brand safety issues. They often do not wish their messaging appearing alongside objectionable content.
  • Fraud: The technology that enables the ecosystem is vulnerable high tech criminals intent on manipulating it for financial gain. Fraud is the biggest threat to the growth of the programmatic ecosystem.
  • Cookies: The cookie, which is the linchpin of most targeting mechanisms, is long overdue for replacement. The technology was never meant for what it is being used for and is arguably the weak link in the system. Additionally, cookies are not pervasive in mobile and mobile is the fastest growing digital platform. Marketers want to be able to target audiences across all platforms.

So, is Programmatic the next big thing? No, It’s already a really, really big thing. Depending on who you ask anywhere from 23% to 85% of marketers have embraced programmatic buying. As is often the case, the real number is probably nearer the middle of that range, but it’s still a big number and growing.

What’s next? Marketing Automation. Plugging customer relationship management (CRM) and internet of things (IOT) data into the ecosystem. Yes, your refrigerator will send a push notification to your car to tell you that you are low on milk and present you a coupon for your favorite brand at the retailer you are about to drive by. And since you aren’t physically driving the car, you’ll just tell it to stop and park.

MediaOcean Musings

Kevin Reynolds · October 5, 2011 ·

MediaOcean

The shot heard around the media planning and buying technology world provoked much commentary. Here’s our two cents:

  • It’s about time. MediaBank (MB) has been making inroads at the holding companies, notably IPG and Publicis. However Omnicom Media Group and WPP’s GroupM seemed to be firmly in the DDS camp and weren’t planning to switch to MediaBank any time soon. Now DDS can spend less time defending business and MB can scale back business development efforts allowing the combined entity to invest further in R&D.
  • MediaBank is further along at the task of developing Digital planning and buying applications. DDS has had a tougher time with iDesk, although the latest version is gaining traction.
  • The back office applications are where the rubber meets the road. The DDS IBM mainframe accounting package (ACCPAK) is mature and the industry standard for traditional media billing. The holding companies have a huge investment in integrating ACCPAK with their data warehouses, dashboards and reporting systems. No way OMG, GroupM or Aegis were rebuilding that infrastructure.
  • DDS has been scaling back staff over the past few years, and quite a few of those talented folks ended up at MB. They are well positioned to lead the integration efforts.
  • Speaking of integration, it is not going to be easy. DDS is based on IBM 3270 mainframe technology with custom built application interfaces. It requires connection to its WAN and proprietary Windows client applications. MediaBank, because of it’s legacy of acquisitions, has .Net, Unix, and Oracle tech stacks. MB has both self hosted and ASP delivery models as well as desktop and web based client applications.  There is little common ground here. The strategy behind integrating the technology will be critical.
  • They seem to have the right guys at the helm. Bill Wise, who put together the first digital ad exchange at RightMedia obviously gets it. So does J.T. Batson, formally of the Rubicon project. These are guys with cutting edge digital experience. Yay. And Michael Donovan is still the guy…. he has owned this space with the holding companies for the past 30 years.


  • When we last reported on this topic there was anticipation around this sort of a development. It’s happening. Very exciting times in the media planning/buying technology space!
