This week, we had the pleasure of exhibiting at NAB Show in Las Vegas, showcasing the latest dynamic ad insertion (DAI) tools and techniques to boost ad performance and increase advertising revenues.

This year, we took our participation to new heights. We presented product demos on every corner of our stand, shared tips on DAI best practice, and took advantage of the opportunity to connect in person with industry friends. And if you were there, it would have been hard to miss our banner at the entrance to West Hall!

For those who couldn’t make it to the show, we’ve rounded up our highlights and key takeaways from our time at NAB Show 2025.

Dynamic ad insertion scales new heights

The show was well-timed as it came after a record-breaking month for Yospace. In March 2025, we stitched 8.4 billion one-to-one addressable ads across our global customer base. This new milestone is especially significant as it was only in July 2024 that we marked 6 billion ads stitched in a single month. The acceleration in the growth of DAI is amazing, and it emphasises the importance of successfully scaling the technology.

Extended DVR with historically resolved breaks

In the streaming age, there are increased viewer expectations for functionality like extended DVR/ rewind windows in live streams. However, until now, efficiently monetising these viewing experiences has been a challenge:

  1. It required “speculative” ad-requests for historic breaks on behalf of all users when they join the stream, regardless of whether they will enter DVR mode or not. This can lead to slow stream start times
  2. Increased ad-decisioning costs associated with ads that will often never be viewed, this in turn impacts campaign pacing algorithms and ad operations’ view of fill rates
  3. Finally, where programmatic demand is in play, the low bid win-to impression ratio associated with these types of use cases will damage SSP demand as SSPs may either stop bidding or bid a lower CPM rate based on their view of the value of the inventory

As a result of these types of viewing experiences, extended DVRs have typically been delivered as “start-over” functionality, but with growing player support for HLS interstitials (SGAI), the ad-tech/ ad operations challenges, as well as the potential scaling considerations, fall away. 

In collaboration with castLabs, we tackled these challenges at NAB Show. We demonstrated how to monetise these historic ad breaks effectively using HLS Interstitials and server-guided ad insertion (SGAI).

Based on Yospace usage data, we estimate that effective monetisation of historic ad breaks  could unlock in excess of $50m of untapped ad revenue potential every month for Yospace customers alone. It also has huge potential for the industry as a whole.

Orchestrator for monetising one-off live events

In collaboration with Capella Systems, we demonstrated how automated live channel creation with dynamic ad insertion can greatly increase the amount of ad inventory available during live events. Orchestrator provides operators with a live dashboard to monitor multiple channels simultaneously. Live feeds come direct from the encoder, eliminating latency, and allowing more in-play ad spots.

Side-by-side ads using SGAI

Using HLS Interstitials, our collaboration with Bitmovin demonstrated side-by-side ads in live and VOD streams. Ad formats like these offer greater flexibility for monetisation alongside in-stream advertising. Squeeze back and L-shaped banners have also been popular topics over the last week.

Award win

Now for the icing on the cake. TVB Europe honored us with a Best of Show award for our extended DVR with historically resolved ad breaks. Go us!

Looking Ahead

With NAB Show now behind us, we’re already gearing up for more events this year. The next big one will be IBC in September, where we’ll continue to share our innovations and insights. We’ll also be at Streaming Tech Sweden, ANGA, Cannes Lions, Inter BEE, Demuxed, Future TV Advertising Global, and more.

If you would like to meet with us, don’t hesitate to get in touch with our dedicated team here. You can also follow us on LinkedIn to see what we’re up to.
