Abstract
The present invention verifies the transmission of a data stream, such as an advertisement, to a receiver in a data network, such as a television set in a cable television network. In particular, the present invention develops and stores a data stream fingerprint prior to transmission of the data stream. During transmission of the data stream, a verifier compiles the fingerprint from the transmitted data stream and compares it to the pre-developed and stored fingerprint. If the fingerprint signal characteristics are within predetermined parameters, the transmission is considered successful.
