How ACR Data Is Collected
Automatic Content Recognition (ACR) technology works by capturing audio or pixel-based fingerprints from content displayed on a smart TV screen and matching those fingerprints against a reference library of known programming. This passive, opt-in collection method runs continuously in the background on participating smart TV devices, picking up both linear broadcast content and over-the-top (OTT) streaming content without requiring set-top box integration. GSDSI's ACR feed pulls together these signals from millions of opted-in households, providing second-by-second viewership data that includes channel tuning events, ad exposure detection, and content-level engagement metrics. The data is refreshed daily and delivered in analyst-ready formats including CSV, JSON, and Parquet.
Common Applications for CTV Data
Media agencies and brand advertisers use ACR data to measure cross-platform reach and frequency, determining how many unique households were exposed to a campaign across linear TV, CTV, and digital at the same time. Programmers and content distributors analyze viewership patterns to inform scheduling, content licensing, and ad inventory pricing decisions. Financial analysts use CTV exposure data as an alternative signal for estimating advertising revenue at media companies mapped to public tickers. Retail and QSR brands combine ACR exposure data with foot traffic signals through GSDSI's Euclidean Feed to perform closed-loop attribution, proving that a CTV ad impression led to an actual store visit within a defined attribution window.
How buyers diligence CTV / ACR data
CTV buyers validate householding logic, OEM/platform coverage, exposure definitions, and whether ACR events can join to identity, mobility, or outcome files without overcounting reach.
