In one embodiment, a personalization application provides emotionally personalized audio content to co-located users. In operation, the personalization application acquires first personalized audio content for a first user based on an emotional state associated with the first user. The personalization application then causes a first audio device associated with the first user to output the first audio content. In addition, the personalization application causes a second audio device associated with a second user that is co-located with the first user to output second audio content while the first audio devices outputs the first audio content. Notably, the second audio content is different from the first audio content.

A system and method for enriching a concept database. The method includes determining, based on at least one signature of a first multimedia data element (MMDE) and signatures of a plurality of existing concepts in the concept database, at least one first concept among the plurality of existing concepts, wherein each of the at least one first concept matches a portion of the at least one signature of the first MMDE; generating a reduced representation of the first MMDE, wherein generating the reduced representation further comprises removing the portion of the first MMDE matching the at least one first concept; comparing the reduced representation of the first MMDE to signatures representing a plurality of second MMDEs to determine a plurality of matching second MMDEs; generating, based on the reduced representation of the first MMDE and the plurality of matching second MMDEs, at least one second concept; and adding the generated at least one second concept to the concept database.

A method for populating a plurality of radio stations on a user device, the method includes receiving the plurality of radio stations, including a radio station signal type, receiving a broadcast area for each of the plurality of radio stations, receiving a request for radio service from the user device, the request for radio service comprising a location of the user device, a user device signal threshold, and a user device antenna capability, wherein the user device antenna capability comprises at least one signal type, calculating a plurality of user device ranges for each of the plurality of radio stations, determining, a plurality of in-range radio stations, filtering, the plurality of in-range radio stations based at least in part on the user device signal threshold, further filtering the plurality of in-range radio stations based at least in part on the user device antenna capability, and transmitting the plurality of in-range radio stations, and related content for the each of the plurality of in-range radio stations.

Tools and techniques are provided for identifying, collecting, and processing music-related content within a radio broadcast environment. In one embodiment, a method is provided for processing music-related broadcast radio data. The method includes receiving a plurality of broadcast radio station signals; identifying each radio station signal as an analog signal or a digitally broadcast signal in response to the identified radio station signals; obtaining a broadcast sample from at least one of the radio stations; identifying at least one music-related information element missing from the broadcast sample; obtaining missing music-related information elements; updating a computer server with the obtained music-related information elements; and generating and communicating a music guide including the updated information to various user devices.

A method and a system for sending alert messages are provided. The method includes defining an alert area associated with an alert event. The method further identifies one or more cells at least partially overlapping with the alert area. The method furthermore performs a passive positioning to determine a first set of communication devices associated with the one or more cells. Thereafter, the method performs an active positioning on the first set of communication devices to identify a second set of communication devices present within the alert area. The method then sends an alert message to the second set of communication devices.

A system and method for the reception of content items, including the ability to handle a plurality of service announcement formats and the ability to select, for a plurality of network access points, the best access point for receiving items.
