What is Addressable TV Advertising?

Addressable TV advertising is an advanced advertising solution that enables broadcasters and OTT providers to show different ads to different households, even if they are watching the same program.

Unlike traditional TV advertising, where the same commercial is shown to all viewers, addressable TV uses data such as location, demographics, viewing habits, and behavioral insights to tailor ads for each household, making the viewing experience more relevant and personalized.

By turning TV into a more targeted platform, addressable TV ensures that ads are connected to viewers’ interests, improving engagement.

This not only enhances the viewing experience but also gives broadcasters and OTT providers the opportunity to generate new revenue, increase CPMs, and offer advertisers better targeting options in a premium space.

How Addressable TV Advertising Works: Technology Behind the Targeting

Addressable TV allows different households watching the same program to see different ads based on their unique data.

Here’s a quick overview of how it works:

  • Set-Top Boxes and Smart TV Environments
    The process begins with the viewer’s device. Whether it’s a set-top box provided by a pay-TV operator or a connected Smart TV, these environments are equipped with the capability to switch or insert ads dynamically.
  • ID Resolution and Audience Matching Technologies
    Tools like Customer Data Platforms (CDPs) and device graphs collect and match audience data to specific households or devices, ensuring ads reach the right viewers.
  • Ad Decisioning and Delivery Engines
    Once the audience is identified, advanced ad decisioning engines determine in real time which ad should be served to which viewer. These platforms consider multiple data signals, campaign rules, frequency caps, and bidding inputs to ensure optimal ad delivery performance.
  • Server-Side and Client-Side Ad Insertion (SSAI vs. CSAI)
    Ads are inserted either server-side (SSAI) for seamless streaming or client-side (CSAI) directly from the device, depending on the platform, ensuring smooth user experience and accurate measurement.
