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.
