Title:
対象を定めた広告に適したリアルタイム視聴者推定およびコマーシャル選択を実施する方法および装置
Document Type and Number:
Japanese Patent JP5172826
Kind Code:
B2
Abstract:
Input measurements from a measurement device are processed as a Markov chain whose transitions depend upon the signal. The desired information related to the device can then be obtained by estimating the state of the signal at a time of interest. A nonlinear filter system can be used to provide an estimate of the signal based on the observation model. The nonlinear filter system may involve a nonlinear filter model and an approximation filter for approximating an optimal nonlinear filter solution. The approximation filter may be a particle filter or a discrete state filter for enabling substantially real-time estimates of the signal based on the observation model. In one application, a click stream (208) entered with respect to a digital set top box (200) of a cable television network is analyzed to determine information regarding users (205) of the digital set top box (206) so that ads (204) can be targeted to the users (205).
