Dynamic Ad Insertion
In the broadcast industry, the way we deliver advertisements is evolving rapidly. Traditionally, ads in linear television broadcasts are sold and scheduled in advance, resulting in a static set of spots shown to all viewers. While this model has served the industry for decades, the rise of streaming video services has introduced a more dynamic approach. Streaming platforms often utilize “instant auctions” for ads, allowing advertisers to target specific viewers and optimize ad delivery in real-time.
Dynamic Ad Insertion (DAI) is a transformative capability that brings these advanced, targeted advertising features to over-the-air (OTA) broadcasting. By leveraging the flexible, IP-based architecture of the ATSC 3.0 (NextGen TV) standard, broadcasters can now narrow the gap between traditional broadcast and modern broadband advertising, enhancing the value of every ad impression.
Why Dynamic Ad Insertion Matters for Broadcasters
DAI offers significant advantages that can lead to increased revenue and a more engaging viewer experience. Instead of a one of a one-size-fits-all approach, DAI enables the delivery of advertisements based on specific criteria, such as a viewer’s geographic location or profiles derived from subscriptions or opt-ins. This means viewers see ads more relevant to them and are as such less likely to find advertisements disruptive, improving audience satisfaction overall.
The improved targeting of DAI also increases their value to marketers, leading to potential new revenue streams. The efficient and scalable nature of ATSC 3.0 (Next Gen TV), also promises to lower distribution cost and reduce the burden on broadband Content Delivery Networks (CDNs). Unlike unicast streaming services where each viewer requires a separate data stream, ATSC 3.0’s one-to-many broadcast model can deliver the same high-quality content and ads to an infinitely scalable number of viewers simultaneously.
How Dynamic Ad Insertion Works
Our approach to Dynamic Ad Insertion (DAI), built specifically for the ATSC 3.0 environment, uses a Client-Side Ad Insertion (CSAI) to ensure advertising can play in an offline environment. Advertisements are delivered to receivers in advance as Non-Real Time (NRT) files, often packaged in DASH segments, and transferred during off-peak hours when more spectrum is available. These ads are then stored locally on the device, with our Data Distribution as a Service (DDaaS) platform managing delivery schedules and enabling precise targeting across different markets.
When a viewer is watching live television, markers embedded in the MPEG Media Transport (MMT) stream signal upcoming ad breaks and point the receiver to the correct file in its cache. At the scheduled time, the player pauses the live stream, plays the locally stored advertisement, and then seamlessly returns to the live broadcast. The result is a smooth, uninterrupted viewing experience for the audience, while broadcasters gain a flexible and reliable way to insert targeted advertising without depending solely on real-time connectivity.
Offline DAI
Our work is centered on making Dynamic Ad Insertion (DAI) reliable even in places where broadband access is limited or inconsistent, such as in our Direct-to-Mobile (D2M) Project in India. To achieve this, we’ve designed an approach where both ad distribution and decision logic function effectively in a broadcast-only environment, without requiring constant connectivity.
At the core of this system is our DDaaS platform, which manages the delivery of Non-Real Time (NRT) ad files. It supports highly flexible scheduling that covers broadcast times, repeats, and recurrence patterns, and enables geographic precision by targeting ads down to designated market areas, postal codes, or even county codes. Using identifiers like App Content ID and Filter Codes, the platform ensures that each receiver processes only the ads that are most relevant to its location and audience.
On the playback side, the MPEG Media Transport (MMT) protocol integrates directly with live streams, providing the signaling needed to insert ads at the right moment. MMT’s efficiency allows broadcasters to deliver high-quality content, including 4K UHD, to both home and mobile devices, while its markers tell the receiver when and where to insert ads.
In disconnected environments, a lightweight Broadcast Application (BA) on the device takes over ad decision-making, managing local ad playback through APIs and keeping storage optimized by clearing outdated content. To further support mobile use, receivers can wake from standby at scheduled times to receive fresh NRT files, conserving battery life while ensuring new ads are always available. Together, these capabilities create a broadcast-first solution that keeps DAI effective and seamless, even when broadband isn’t guaranteed.
Conclusion
By combining pre-positioned ad content, intelligent local playback, and flexible broadcast delivery, our approach to Dynamic Ad Insertion makes advertising reliable, seamless, and scalable in the ATSC 3.0 era. Whether in advanced connected markets or in regions with limited broadband access, broadcasters can deliver targeted, high-quality ads without disruption, while audiences enjoy a smooth viewing experience. This balance of broadcast efficiency and personalization is what makes our solution a future-proof path for monetizing NextGen TV and Direct-to-Mobile services worldwide.
