摘要： A broadcast verification system includes a CM creation device for creating a CM signal to be included in a television signal and a verification device for receiving the television broadcast signal transmitted from a broadcast station and checking the CM signal. The CM creation device includes an encoder for superimposing unique ID information identifying the CM signal to the CM signal at a predetermined position. The verification device includes a decoder for extracting the ID information from the television broadcast signal, a verification section for verifying, on the basis of the extracted ID information and a CM schedule supplied from the broadcast station through a path different from that for the television broadcast signal, whether the CM has been broadcast according to the schedule, and a verification information storage means for storing verification information containing at least the verification result, the broadcasting time of the CM, and the broadcast channel.
