Media objects are transformed into active, connected objects via identifiers embedded into them or their containers. In the context of a user's playback experience, a decoding process extracts the identifier from a media object and possibly additional context information and forwards it to a server.

Media objects are transformed into active, connected objects via identifiers embedded into them or their containers. In the context of a user's playback experience, a decoding process extracts the identifier from a media object and possibly additional context information and forwards it to a server. The server, in turn, maps the identifier to an action, such as returning metadata, re-directing the request to one or more other servers, requesting information from another server to identify the media object, etc. The linking process applies to broadcast objects as well as objects transmitted over networks in streaming and compressed file formats.

We claim: 1. A method of linking an audio signal to metadata or actions comprising: deriving an identifier from an audio signal received by a user device, the identifier identifying a broadcaster or distributor of the audio signal; obtaining context information at the user device related to the audio signal; making a request for metadata using the identifier and the context information wherein the request includes transmitting the identifier and the context information to a server; by the server, deriving an object ID of an audio object in the audio signal using the identifier and the context information; determining the metadata corresponding to the object ID at the server or another server; and presenting at least a portion of the metadata on the user device. 2. The method of claim 1 wherein the metadata includes one or more links and the one or more links includes a link to an electronic transaction for purchasing a product related to the audio signal. 3. The method of claim 1 wherein the metadata includes one or more links and the one or more links includes a link to a web page. 4. The method of claim 1 wherein the metadata includes one or more links and the one or more links includes a link to a programmatic action for retrieving video or audio via streaming or file download delivery. 5. The method of claim 1 wherein the metadata includes one or more links and the one or more links includes a link to a a database for additional information related to the audio signal. 6. A computer readable medium on which is stored instructions which, when executed by a computer, perform a method of linking an audio signal to metadata or actions comprising: deriving an identifier from an audio signal received by a user device, the identifier identifying a broadcaster or distributor of the audio signal; obtaining context information at the user device related to the audio signal; making a request for metadata using the identifier and the context information wherein the request includes transmitting the identifier and the context information to a server; by the server, deriving an object ID of an audio object in the audio signal using the identifier and the context information; determining the metadata corresponding to the object ID at the server or another server; and presenting at least a portion of the metadata on the user device.
