    Abstract: An end user can sample a radio or television broadcast, generate a user representation of the broadcast sample, and send the user representation to a comparison system, which also receives known representations of content broadcast by multiple different stations. The known representations are stored in a continuous fashion, and represent actually broadcast content. The comparison system identifies the source of the broadcast sample by comparing the user representation to the known representations associated with each of the different stations using a bit count method, such as the Hamming distance. By comparing two representations of content that was actually broadcast, a broadcast source can be identified without requiring the use of watermarks, timestamps, or a database of discreet content items.

    Abstract: Media monitoring using multiple types of signatures is disclosed. Example methods disclosed herein include sending a first indication to a device meter to indicate that media monitored by the meter corresponds to first reference media in response to determining that a media signature of a first type reported by the meter matched a first reference signature associated with the first reference media. Disclosed example methods also include, after sending the first indication, comparing media signatures of a second type reported by the meter with reference signatures of the second type associated with the first reference media. Disclosed example methods further include, in response to determining that the media signatures of the second type fail to match the reference signatures of the second type, sending a second indication to the meter to indicate that the media monitored by the meter no longer corresponds to the first reference media.

    Abstract: A system and method are provided for enabling a plurality of media feeds, such as internet radio stations, to be played through a standard media player, such as a radio receiving device, using the tuning or input selection controls of the media player to control the selection of which media feed to play. Identification signatures are added to channels and transmitted to the media player by transmitter. A controller captures the feedback of the media player and, if it detects one of the signature signals in the feedback, instructs the media feed selector to select a media feed which corresponds to the detected identification signature. The selected audio feed may then be transmitted to the media player on the corresponding channel for playback.

    Abstract: Methods and apparatus to identify media content using temporal signal characteristics are disclosed. An example method includes generating a reference signature based on a reference signal corresponding to known media, generating sums based on peaks in a media signal corresponding to media, identifying signal peaks based on the generated sums, generating a second signature based on normalized curve features, wherein the normalized curve features respectively correspond to the identified signal peaks at a corresponding temporal locations of the corresponding signal peak, and determining whether the media signal corresponds to the reference signal based on a comparison of the reference signature and the second signature.
