Enhanced video programming system and method utilizing user-profile information
Maintaining a file specifying a “donut” of dynamic, hierarchical, shared user-profile information. The donut contains a user profile or acts as a key to a data repository containing it, and it specifies user-profile information such as user characteristics, viewing preferences, hobbies, and spending habits. The donut is accessed by browser programs, associated web server programs, and other applications for use in routing content to the user associated with the donut.
1. A method for compiling and maintaining information for use in routing and transmitting content to a machine via a network by specifying particular fields within a computer-readable medium, the method comprising:
receiving user activity information for updating a first user profile;
specifying in the medium user profile information for determining a uniform resource identifier for identifying content to transmit to the machine and an identification of the machine;
inheriting user profile attributes into the first user profile from a group of which the user is a member;
storing the first user profile information in a hierarchical attribute value-pair data structure; and
selecting content for at least one user based on examination of at least one other user profile,
wherein the selected content is selected based on the first user profile and is used to enhance an audio video program.
2. The method of claim 1 , wherein selecting content for at least one user further comprises selecting content for a group of users.
3. The method of claim 1 , wherein selecting content for at least one user further comprises examining profiles of users in one or more groups of which the at least one user is a member.
4. The method of claim 3 , wherein examining profiles of users in one or more groups of which the at least one user is a member further comprises examining profiles of one or more subsets of the one or more groups of which the at least one user is a member.
5. The method of claim 1 , wherein selecting content for at least one user further comprises examining profiles of users in one or more groups of which the at least one user is a not a member.
