Document Type and Number:
WIPO Patent Application WO/2002/015596
Kind Code:
A1
Abstract:
CM feature extracting means (22) extracts the feature (24) in the section corresponding to a CM (commercial message) from the broadcast signal received by a reception facility (21). A collating section (23) collates the feature (24) with features of CMs registered in a DB (3). If the feature (24) is judged to be not contained in the DB (3), the collating section (23) registers the feature (24) in the DB (3) as a new CM. A Feature calculation section (42) extracts a feature (44) from a broadcast wave received by a reception facility (41). Collating means (43) collates the feature (44) with features of CMs stored in the DB (3). When the feature (44) coincides with one of the features, the collating unit(4) sends the results (45) of the collation to a recording unit (5). The recording unit (5) creates a report (51) on the basis of the results (45) to send the report (51) to a client (1). A broadcast confirmation company (6) receives a broadcast confirmation consignment commission (11) in consideration of the report (51).
