Method and system for registering a user preference

A system for registering a user preference for a program (201) in at least one of a collection (221) of preference profiles for recording a set of user preferences, comprising

• receiving means (10) for receiving an input (211, 212) representing the user preference for the program (201),
• scoring means (14) for determining for each preference profile from said collection (221) a score for the program (201), said score indicating the degree of agreement of the program (201) with said preference profile,
• updating means for determining if the input (211, 212) represents a positive user preference, and if so updating a preference profile from said collection (221) having a relatively high score with respect to the scores of all the preference profiles from said collection (221) to reflect the positive user preference for the program (201), and if the input (211, 212) represents a negative user preference, updating a preference profile from said collection (221) having a relatively low score with respect to the scores of all the preference profiles from said collection (221) to reflect the negative user preference for the program (201).
