Abstract: A verification system that injects a inaudible identification code into a broadcast advertisement immediately prior to its radio frequency transmission is disclosed. An amplitude modulated sample sequence called a “digital artifact” containing, for example, a date and time code, is generated and inserted into the audio or video or composite audio and video data stream called a content “carrier.” The combined data signal is converted from a digital stream to an analog signal and processed by standard broadcast transmission and transmitted in the radio frequency spectrum in the conventional manner. A radio frequency spectrum radio or television receiver receives the broadcast signal and converts to a digital data stream. A decoder processes the transmitted content carrier and extracts the digital artifact from the data stream. The derived information is evaluated, quantified, and transmitted to a central control point where it is compared with original reference and identification data.

Abstract: An affiliate site commands the central site to construct a unique broadcast event log through the affiliate site's command browser. The sequenced data stream of broadcast content is combined with a digital artifact inserted into the digitized broadcast video and/or audio content immediately prior to the data transmission process. Transmission to the affiliate site is accomplished utilizing Internet Protocol. Upon reception at the destination, the commercial advertising or prepared program content is input to the affiliate site's system, routed to the broadcast production system, and in turn, processed by the broadcast transmission site, where it is converted from a digital to an analog signal, and transmitted electromagnetically in the radio frequency spectrum by the broadcast transmitter.

Abstract: A system for the insertion of microthreads in transmitted data is provided. The system includes a digital content system providing carrier data, such as sampled audio data. A microthread insertion system coupled to the digital content system generates a composite data sequence that includes the carrier data and microthread data, such as broadcast verification data. The microthread data is camouflaged using the carrier data, such as by including in the audio signal in a manner that allows it to be detected but which does not noticeably affect the audio signal for listeners.
