Abstract
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.
Claims29
A method of establishing an on-line collection of media titles, comprising the steps of:
- extracting an identifier steganographically encoded in a media signal;
- sending the identifier to a database;
- and
- requesting the database to add a title associated with the media signal to an on-line collection.
A system to interact with an on-line collection of media titles stored in a database, said system comprising:
- a detector to extract an embedded watermark from a media signal, the watermark including identifying information for the media signal;
- a module to send the identifying information to the database;
- and
- a module to receive data from the database in response to the identifying information.
An apparatus to interact with a media signal, said apparatus comprising:
- a storage device;
- a processing unit;
- and
- a local application stored in said storage device and processed by said processing unit, said local application operating to:
- i) extract an identifier from the media signal, the identifier being steganographically encoded into the media signal, and to ii) send the identifier to a database to associate the media signal with an on-line collection maintained by the database.
A method of operating a system to create and manage a library of on-line media titles, said method comprising the steps of:
- receiving a media identifier from a user that has been extracted from steganographically encoded information in a media signal;
- determining a title that corresponds to the media identifier;
- identifying the user;
- and
- adding the media title to an on-line library of media titles associated with the user.
An apparatus to interact with a streaming media signal, said apparatus comprising:
- a storage device;
- a processing unit;
- and
- a local application stored in said storage device and processed by said processing unit, said local application operating to:
- i) extract an identifier from the streaming media signal, and to ii) send the identifier to a database to associate the streaming media signal with an on-line library collection maintained by the database.
