Abstract

A plurality of information processing apparatus can share preference information each of the apparatus has. There is provided a preference information processing system which has a plurality of information processing apparatus adapted to share preference information acquired on the basis of user operations for contents on a recording apparatus communicable with each of the information processing apparatus, wherein each of the plurality of information processing apparatus includes a user operation managing section that manages user operations for the contents, an attribute information managing section that manages attribute information of the contents, an action managing section that manages actions for the contents, and a general control section that controls these managing sections, and communicates with the recording apparatus, and the recording apparatus contains a preference information database and a preference information control section that manages/edits preference information, which are shared by the plurality of information processing apparatus.

Claims

1. A preference information processing system which has a plurality of information processing apparatus adapted to share preference information acquired on the basis of user operations for contents on a recording apparatus communicable with each of the information processing apparatus, wherein

each of the plurality of information processing apparatus includes a user operation managing section that manages user operations for the contents, an attribute information managing section that manages attribute information of the contents, an action managing section that manages actions for the contents, and a general control section that controls the user operation managing section, the attribute information managing section and the action managing section, and communicates with the recording apparatus, and

the recording apparatus contains a preference information database and a preference information control section that manages/edits preference information, which are shared by the plurality of information processing apparatus.

2. The system according to claim 1, wherein the preference information database uses two database formats or a contents-supplying-medium-dependent database format for preference information specific to each of the information processing apparatus, and a basic database format for knowing the essence of the liking of the user regardless of the type of contents-supplying-medium.

3. The system according to claim 1, wherein the preference information control section contained in the recording apparatus communicates with the general control section of each of the information processing apparatus, using an inquiry command, an answer command and a study information command, and updates the preference information database according to the study information command.

4. The system according to claim 1, wherein the general control section of each of the information processing apparatus communicates with the preference information control section of the recording apparatus, using an inquiry command, an answer command and a study information command, and controls the actions taken by each of the action managing sections for the contents according to the answer command from the preference information control section of the recording apparatus.

5. A recording apparatus communicable with a plurality of information processing apparatus and adapted to share preference information acquired on the basis of user operations for contents in the plurality of information processing apparatus, which contains a preference information database and a preference information control section that manages/edits preference information, which are shared by the plurality of information processing apparatus.

6. The apparatus according to claim 5, wherein the preference information database uses two database formats or a contents-supplying-medium-dependent database format for preference information specific to each of the information, processing apparatus, and a basic database format for knowing the essence of the liking of the user regardless of the type of contents-supplying-medium.

7. The apparatus according to claim 5, wherein the preference information control section communicates with the general control section of each of the information processing apparatus, using an inquiry command, an answer command and a study information command, and updates the preference information database according to the study information command.

8. An information processing apparatus communicable with a recording apparatus containing a preference information control section for managing/editing preference information acquired on the basis of user operations for contents and a preference information database controlled by the preference information control section, which includes a user operation managing section that manages user operations for the contents, an attribute information managing section that manages attribute information of the contents, an action managing section that manages actions for the contents, and a general control section that controls the user operation managing section, the attribute information managing section and the action managing section, and communicates with the recording apparatus.

9. The apparatus according to claim 8, wherein the general control section communicates with the preference information control section of the recording apparatus, using an inquiry command, an answer command and a study information command, and controls the actions taken by the action managing section for the contents according to the answer command from the preference information control section of the recording apparatus.

10. A communication method to be used in a preference information processing system having a plurality of information processing apparatus adapted to share preference information acquired on the basis of user operations for contents on a recording apparatus communicable with each of the information processing apparatus, the method comprising:

an inquiry packet transmission step of transmitting a packet for inquiring about a preference value from each of the information processing apparatus to the recording apparatus; and

an answer packet transmission step of transmitting the preference value as the answer to the inquiry packet in the inquiry packet transmission step from the recording apparatus to the corresponding information processing apparatus.

11. The method according to claim 10, further comprising:

a step of transmitting information to be used for altering the preference value in the recording apparatus from each of the information processing apparatus to the recording apparatus.

12. The method according to claim 10, wherein a packet describing the keyword to be used for inquiring the preference value on the target of retrieval is transmitted in the inquiry packet transmission step.

13. The method according to claim 10, wherein a packet describing two kinds of preference values or a medium-dependent preference value and a basic preference value respectively conforming to two database formats or a contents-supplying-medium-dependent database format for specific preference information in each of the information processing apparatus and a basic database format for knowing the essence of the liking of the user regardless of the type of contents-supplying-medium is transmitted in response to the keyword for inquiring a preference value in the answer packet transmission step.
