Abstract

A system of the present invention is structured based on a connection between an information distributing unit that processes distributed contents information and a client unit of a user via a network such that they can communicate with each other. The contents information selected based on profile information of the user is transmitted from the information distributing unit to the client unit. The system makes the user input evaluation information relating to the evaluation of the transmitted contents information. The contents information to be distributed to the user is changed based on the input evaluation information.

Claims

1. A contents distribution method that is executed by using a contents information management system that is structured based on a connection between a contents information processing device that processes distributed contents information and an information terminal unit of a user via a network such that they can communicate with each other, the contents distribution method comprising:

a contents information transmission of transmitting the contents information selected based on profile information of the user, from the contents information processing device to the information terminal unit;

an evaluation information input step of making the user input evaluation information relating to the evaluation of the contents information that has been transmitted at the contents information transmission step, in the information terminal unit; and

a contents information changing step of changing the contents information to be distributed to the information terminal unit of the user, based on the evaluation information that has been input at the evaluation information input step.

2. The contents distribution method according to claim 1, wherein the contents information includes at least one video block, and the contents distribution method further comprises:

a category information storing step of storing category information relating to the category of the video block;

a weight information storing step of storing weight information of the category information of the video block; and

a transmission decision step of deciding whether the video block is to be transmitted to the information terminal unit of the user or not, based on the weight information that has been stored at the weight information storing step.

3. The contents distribution method according to claim 2, further comprising:

a user profile information changing step of changing the profile information of the user based on the evaluation information.

4. The contents distribution method according to claim 2, wherein the category information storing step comprises a category information determination step that determines the category information based on at least one of scenario data relating to the scenario of the contents information, video data, and sound data.

5. The contents distribution method according to claim 2, wherein the category information is classified into a hierarchy of two or more layers, and when the weight information of the category information of a lower order has been changed, the weight information of the category information of a higher order is also changed.

6. The contents distribution method according to claim 2, wherein

the contents information includes at least one object,

the category information and the weight information are set for each object, and

the evaluation information input step makes the user input the evaluation information relating to the evaluation of the object of the contents information that has been transmitted at the contents information transmission step.

7. A contents information processing device that is connected to an information terminal unit of a user via a network, and that processes contents information that is distributed to the information terminal unit, the contents information processing device comprising:

a contents information transmitting unit that transmits the contents information selected based on profile information of the user, to the information terminal unit;

an evaluation information receiving unit that receives from the information terminal unit, evaluation information relating to the user evaluation of the contents information that has been transmitted by the contents information transmitting unit; and

a contents information changing unit that changes the contents information to be distributed to the information terminal unit of the user, based on the evaluation information that has been received by the evaluation information receiving unit.
