A Per-Object-Granularity Tracking Mechanism and System for Interactive TV Viewership Estimation and Program Rating in Real-Time

TV Program ratings directly affect the decisions of the advertisers and TV stations’ program offerings. The TV program providers use the television ratings reports to offer appropriate programs as well as attract advertisers. In this paper, we propose a framework for TV audience estimates and program rating using a per-object-granularity tracking mechanism for interactive TV content tracking in real-time. It can be applied to Live TV broadcasting environment as well as recorded broadcasting environment. The major components of the proposed tracking architecture are an Interactive TV content creation tool powered by hotlinked video technology, a tracking information delivery framework with live interactive content insertion capability, an Interactive TV content receiver and tracking servers. The proposed mechanism and system in this paper enables a broadcast station or a rating agency to automatically perform tracking functions in real time, based on viewer’s action as well as on the content of audiovisual programming.
