A method and apparatus for the identification and verification of audio transmission segments, such as may be broadcast by a radio station, consists of the generation of a data stream corresponding in duration to the length of the program segment and including both cumulative time data and segment identification data. The data stream is combined with the program segment to which it relates in a manner in which the data is inaudible on conventional reception apparatus and which does not significantly degrade the audio quality of the program segment. A reception facility is provided to extract the data stream from the recorded audio and compare the data therein with reference data for the transmission, including intended length and time of the segment. By such a comparison verification of the broadcast can be accomplished.
An apparatus for adding identifying indicia to an audio signal segment and subsequently recovering said indicia, comprising: means for combining an inaudible data string having a series of program segment timing marks and at least one presentation of program segment identification data with said aud
An apparatus for adding identifying indicia to an audio signal segment and subsequently recovering said indicia, comprising: means for combining an inaudible data string having a series of program segment timing marks and at least one presentation of program segment identification data with said audio signal to form an encoded program segment having a non-degraded audio signal portion, at least the timing marks portion of said data string extending for the length of the non-degraded audio signal portion; a broadcast station for transmitting said encoded program segment; a reception station for receiving the transmitted program segment, said reception station comprising means for identifying said inaudible data string portion of said encoded program segment and generating a data signal having said program identification data and timing marks; means for associating said program identification data and timing marks of said data signal with reference program segment data including segment length, identification and airing information; and means for performing an analysis of said program segment as broadcast by use of said program identification data, timing marks, and corresponding reference program segment data.
