    Abstract: Example local devices disclosed herein include memory including a set of reference fingerprints corresponding to media, the set of reference fingerprints from a remote device different from the local device and one or more processor circuits to execute machine readable instructions to generate a monitored fingerprint of the media presented at a location and compare the monitored fingerprint to at least some of the set of reference fingerprints from the remote device. Additionally, the one or more processor circuits are to determine an amount of time that has passed since the media started and after a match between the monitored fingerprint and one or more reference fingerprints of the set of reference fingerprints, cause transmission of audience measurement information to identify the media, the audience measurement information including data indicative of the amount of time that has passed since the media started.

    Abstract: Travel-related-information messages (TRIMS) are received from one or more information sources, and information included in the messages is separated into a first (e.g. TPEG™) or second (e.g. TPEG+) group. A broadcast area to which the information included in the TRIMs is to be broadcast is determined. A further determination indicates that a subset of information assigned to the first group is to be reassigned to the second group. The subset of information is reassigned from the first group to the second group based on parameters associated with the broadcast area. The information included in the first group and the second group is delivered to one or more processing modules that generate a first TRIM reporting message using information included in the first group and a second TRIM reporting message using information included in the second group.

    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.
