Delivering content

A media player in the form of a computer program on a computer recordable medium, the media player comprising:

• an output component for outputting media content to a user;
• a modelling module connected to the user model and comprising:
• an interface to collect user actions and update a classification of the user in the user model based on those actions;
• an interface to receive user inputs to update the user model;
• and
• an interface to download new rules into the user model to alter a business logic of the user model;
• an input component configured to receive a content identification document identifying pieces of content to the output to the user by the output component;
• and
• a content modifier configured to modify the document based on a user model of the user accessible by the content modifier, the content modifier operable to filter out at least one piece of content identified by the content document to generate a modified identification document, wherein the output component is configured to interpret each piece of content identified in the modified identification document for outputting to the user, wherein the filtered out piece(s) of content is not provided to the user, wherein the behaviour of the content modifier is changed over time without any change to the logical structure of the user device.

A method of outputting media content from a user device comprising:

• receiving a content identification document identifying pieces of content to be output to the user by the output component:
• providing a user model of a user, the user model comprising personal information of the user;
• collecting user actions and updating a classification of the user in the user model based on those actions;
• receiving user inputs to update the user model;
• and
• downloading new rules into the user model to alter a business logic of the user model;
• modifying the document received by the input component based on the user model of the user, by filtering out at least one piece of content identified by the content document to generate a modified identification document, wherein the behaviour of the content modifier is changed over time without any change to the logical structure of the user device;
• and
• outputting media content to a user by interpreting each piece of content identified in the modified identification document for outputting to the user, wherein the filtered out piece(s) of content is not provided to the user.
