摘要

A CM feature data extracting unit 22 extracts a feature data 24 of a section corresponding to a CM from broadcasting signals received by a receiving facility 21. A checking portion 23 checks the feature data 24 against a CM feature data registered with a DB 3. The checking portion 23 registers, with the DB 3, the CM feature data 24 determined not being included in the DB 3 as a new CM. The feature data calculating portion 42 extracts a feature data 44 from broadcast waves received by a receiving facility 41. A checking unit 43 checks the feature data 44 against a CM feature datatored with the DB 3. When they agree, a checking portion 4 sends out a checking result 45 to a recording portion 5. The recording portion 5 creates a report 51 from the checking result 45 and submits the report 51 to a client 1. A broadcast checker 6 receives a broadcast checking charge 11 in compensation for the report 51.
