“Intel® Audience Impression Metrics Suite (Intel® AIM Suite) enables network operators, content providers, advertising agencies and service providers to deliver relevant messages and gauge the effectiveness of their networks and content like never before.
Intel AIM Suite detects the number of viewers, determines their gender and age group, and measures dwell time. This data can be used in real-time to tailor on-screen content based on the demographics of current viewers. For campaign planning and ROI measurement, AIM Suite data can be correlated with Proof-of-Play data to determine content-specific viewership metrics by demographics and time of day.”
