A server receives a message from a subscriber. The message includes a subscriber identifier and one or more one or more first identifying attributes associated with a first media-work played-out by the subscriber. The server performs a first-level match between the first identifying attributes and unique identifiers included in a database. In response to the first-level match indicating that the first identifying attributes do not include any of unique identifiers, the server performs a second-level match, which compares the first identifying attributes to content attributes of different media-works linked to the unique identifiers. In response to the second-level match identifying one or more matching first identifying attributes to the content attributes that are linked to a particular unique identifier included in the database, the server selects enhanced content based on the particular unique identifier, and delivers that enhanced content to the subscriber.

Some examples include a computing device that receives media content to distribute to a plurality of electronic devices. The computing device may receive an indication of first data to relate to the media content for distribution to the plurality of electronic devices. A portion of the multimedia content may be decoded to enable a determination that the media content already has second data embedded in the media content. A psychoacoustic mask may be extracted from the media content and subtracted from the received media content to remove the embedded second data. The first data may be associated with the media content by either embedding third data in the media content, or by embedding the first data in the media content.

Over-the-air radio broadcast signals are commonly used to deliver a variety of programming content (e.g., audio, etc.) to radio receiver systems. Supplemental data (e.g., metadata) may be provided to radio broadcast receiver systems, where such supplemental data is associated with the programming content delivered via the over-the-air radio broadcast signals. In exemplary embodiments described herein, a radio receiver system receives both (i) primary programming content via over-the-air radio broadcast transmission, and (ii) metadata related to the programming content via wireless Internet. This use of metadata provides a user with an enhanced experience regardless of the type of terrestrial broadcast signal that is received at the user's radio receiver system. Users receiving radio broadcast signals at a receiver system may view images, videos, multimedia displays, text, etc., that is related to the programming content received via the over-the-air radio broadcast signals.

A method and system for assigning a multimedia content element to a user. The method includes generating at least one signature to the multimedia content element; determining, based on the generated at least one signature, whether the multimedia content element exists in a database; and assigning a unique identifier of the user to the multimedia content element, when it is determined that the multimedia content element does not exist in the database.

An electronic device includes a display screen and circuitry. The circuitry receives a first frequency modulated (FM) signal from a first FM radio transmitter, via a first FM radio channel. The first FM signal comprises a broadcast data signal that includes an audio segment of aural information of a performer-of-interest at of a live event, text information associated with the audio segment, and synchronization information. The synchronization information is associated with the text information and the audio segment. The circuitry extracts the synchronization information from a plurality of data packets of the broadcast data signal. The circuitry extracts a portion of the text information from the extracted plurality of data packets of the broadcast data signal based on the extracted synchronization information. The circuitry controls display of the extracted portion of the text information on the display screen.
