True is a value within the Loyalty - Frequent Visitor attribute on the Trillboards DOOH network. Across the last 30 days, the Trillboards Federated Edge Intelligence Network (FEIN) emitted 0 observations tagged with this value across 0 approved screens. The attribute lives in the Trillboards segtax=600 namespace — a CV-unique signal layer that captures audience characteristics no IAB Audience Taxonomy 1.1 segment expresses cleanly. Devices observed on >=4 distinct calendar days within the trailing 30-day window at this partner-screen network. Cross-day stable identity sourced from coalesce(raw_ble_mac, raw_mdns_host, stable_payload_hash, raw_signal_hash). Aggregated per (screen, segment_type) with k-anonymity floor of 5 distinct devices. Emitted only when at least 5 devices match the threshold to preserve privacy.
What this attribute value means for buyers: True cohorts surface most often in surfaces, ranked by network share. Grocery carries 0 approved screens at an average floor of — CPM; Convenience and Retail hold meaningful share too. Trillboards venue mix is dominated by high-foot-traffic indoor surfaces — grocery, convenience, recreational, retail, pharmacies — and every cohort signal you see on this page is anchored to one of those venues, with the on-device CV pipeline tagging the observation while the cloud Gemini call cross-validates the cohort. The audience is real, in-the-wild human attention, not panel inference.
Activation: because segtax=600 attributes don't have an IAB ancestor, partners that fetch Trillboards inventory through the SSP-side OpenRTB feed need a dictionary supporting the Trillboards namespace. Trillboards publishes the segtax=600 catalog in the open-source @trillboards/iab-taxonomy npm package; DSPs that prefer not to integrate the namespace can still target the underlying observation via the IAB AT 1.1 cohort layer that Gemini emits in parallel for every observation. Pair True with a venue filter and a daypart restriction to push effective CPM lower while holding completion rate above 90%. With 0 observations in 30 days, True sits in the long-tail — useful for niche brand-fit creatives, not for scaled flights on the Trillboards network.
Why segtax=600 instead of IAB AT 1.1: the IAB Audience Taxonomy is rich on demographics and broad-interest cohorts, but it carries no codes for things like cohort composition (is this a solo viewer, a pair, a small group?), intent stage in the funnel, or attire-driven income proxies. The Trillboards CV pipeline produces those signals directly from the scene, with on-device person detection and gaze tracking feeding the edge layer and the cloud reasoning model layering structured cohort tags on top. Loyalty - Frequent Visitor is one of the headline classes in that catalog. Every observation is cohort-level only, aggregated at the screen-window grain with k-anonymity floors, and never carries a per-person attribute — Trillboards' privacy contract is enforced both at the API and at the data-layer. See the IAB AT 1.1 index for portable cohort targeting; see this catalog for the signals that make DOOH distinct.
