    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: Disclosed is a broadcasting signal receiving apparatus for controlling use of a broadcasting program using a signature in program information and a method thereof. The broadcasting signal receiving apparatus includes a communicating unit for receiving a broadcasting signal, an extracting unit for extracting a broadcasting program and program information from the received broadcasting signal, and a determining unit configured to generate a temporal signature for confirmation (confirmation signature) which determines whether the program information is changed or not from the original program information and determine validity of the program information by comparing a signature included in the extracted program information with the confirmation signature.

    Abstract: A portable device is used to capture, in real time, data sufficient to identify an item, such as a product or service promoted, or a music track played, on a broadcast medium such as radio or television. The capture device can be a standalone implementation, or an application program executable on a personal communication device such as a cell phone or Blackberry. The capture device communicates the captured data to a remote server via a selected wired or wireless channel, or the internet, and the server provides services to support the user in responding to the radio or television broadcast item that corresponds to the captured data. The server on demand downloads to the user additional digital content associated with the identified radio broadcast item.

    Abstract: A user (102) hears an audio program being broadcast and can record a sample of the audio. The sample is then conveyed to an analyzing means (106) to determine to which broadcast station the user is listening. The analyzing means monitors many broadcast channels. Thus, characteristics of the audio sample and samples taken from the broadcast channels can be compared to find a match. Broadcast information pertaining to the broadcast channel from which the match was found may then be reported back to the user, combined with an advertisement of a promotion, prize notification, discount offers, and other information specific for a certain radio station for example.

    Abstract: Methods and apparatus to identify media content using temporal signal characteristics are disclosed. An example method to identify media content includes receiving a reference signal corresponding to known media content and generating a reference signature based on the reference signal. The method further includes generating a plurality of sums based on peaks in the media signal and identifying one or more signal peaks based on the generated sums. The method then generates a second signature based on a plurality of normalized curve features, wherein each normalized curve feature corresponds to a signal peak at the temporal location of the signal peak, and determines whether the media signal corresponds to the reference signal based a comparison of the reference signature and the second signature.
