Abstract

A contents receiving device may automatically receive contents, and a recording medium may store a contents receiving program. The contents receiving device may refer to an agent table, receive contents having the greatest weight of the agent having the least preference deviation as a top priority from a contents providing server or a P2P network, and store the contents in a contents storage unit. Therefore, the contents receiving device and a device for operating the contents receiving program may automatically download contents satisfying the user'"'"'s preference. Further, the devices may allow easy finding of user preferences on the contents and similarities on contents preference with respective agents.

Claims

1. A contents receiving device for downloading contents from a contents providing server in a peer-to-peer (P2P) network, the device comprising:

a contents storage unit for storing contents;

a contents table storage unit for storing a contents table including a list of contents stored in the contents storage unit and weight information for indicating a content user'"'"'s preference on the respective contents;

an agent table storage unit for storing an agent table including a list of agents sharing the weight information and preference deviation information on the contents for the respective agents,

where the preference deviation information is generated based on differences between values corresponding to weight information of an agent for contents and values corresponding to weight information of the contents receiving device for the-contents;

an agent table manager for updating preference deviation information of the agent table; and

a contents receiving processor for referring to the agent table, selecting an agent having a least preference deviation from the list of agents, receiving contents having a greatest weight among a plurality of contents of the selected agent as a top priority from the contents providing server, and storing the received contents.

2. The contents receiving device of claim 1, further comprising a contents reproducer for reproducing the contents stored in the contents storage unit and applying a reproduction degree of the corresponding contents of weight information of the contents table.

3. The contents receiving device of claim 1, where the agent table manager updates preference deviation information of the agent table by using the difference between weight information of the contents table and weight information of the contents possessed by the agent.

4. The contents receiving device of claim 1, where the agent table manager calculates a preference deviation on a new agent, and changes the agent on a list of the agent table that has a preference deviation greater than that of the new agent with the new agent.

5. The contents receiving device of claim 1, further comprising a contents list display for displaying a list of contents included in the contents table to a display device.

6. The contents receiving device of claim 5, where the contents list display displays the list of contents included in the contents table according to an order of weight information.

7. The contents receiving device of claim 1, where the weight information is calculated based on a rate of a total amount and a used amount of corresponding contents, and a reproduction degree is applied to the weight information while reproducing the contents,

where the preference deviation information is generated based on differences of contents included by the agent and the contents receiving device.

8. A contents receiving device for downloading contents from a peer-to-peer (P2P) network including a plurality of P2P nodes, the device comprising:

a contents storage unit for storing contents;

a contents table storage unit for storing a contents table including a list of contents stored in the contents storage unit and weight information for indicating a content user'"'"'s preference on the respective contents;

an agent table storage unit for storing an agent table including a list of agents sharing the weight information and preference deviation information on the contents for the respective agents,

where the preference deviation information is generated based on differences between values corresponding to weight information of an agent for contents and values corresponding to weight information of the contents receiving device for the-contents;

an agent table manager for updating preference deviation information of the agent table; and

a contents receiving processor for referring to the agent table, selecting an agent having a least preference deviation from the list of agents, receiving contents having a greatest weight among a plurality of contents of the selected agent as a top priority from the P2P network, and storing the received contents.

9. The contents receiving device of claim 8, further comprising a contents transmission processor for providing the contents of the P2P node in response to the request of providing contents stored in the contents storage unit from P2P node.

10. The contents receiving device of claim 8, where the weight information is calculated based on the rate of a total amount and a used amount of corresponding contents, and a reproduction degree is applied to the weight information while reproducing the contents,

where the preference deviation information is generated based on differences of contents included by the agent and the contents receiving device.

11. A non-transitory recording medium for storing a program for storing contents received from a contents providing server into a contents storage unit in a peer-to-peer (P2P) network, the non-transitory recording medium comprising functions of:

storing a contents table including a list of contents stored in the contents storage unit and weight information for indicating a preference degree of a contents user on the respective contents;

storing an agent table including a list of agents sharing the weight information and preference deviation information on the respective contents of the agents,

where the preference deviation information is generated based on differences between values corresponding to weight information of an agent for contents and values corresponding to weight information of the recording medium for the contents;

updating preference deviation information of the agent table by using the difference between weight information and the contents table, and weight information of contents possessed by the agent;

referring to the agent table, selecting an agent having a least preference deviation from the list of agents; and

receiving contents having a greatest weight among a plurality of contents of the selected agent as a top priority from the contents providing server, and storing the received contents in the contents storage unit.

12. The recording medium of claim 11, further comprising reproducing the contents stored in the contents storage unit to a contents reproducer, and applying the reproduction degree of the corresponding contents to weight information of the contents table.

13. The recording medium of claim 11, further comprising updating a list of agents included in the agent table according to an order having the agent of the least preference deviation as a top priority.

14. The recording medium of claim 11, further comprising displaying the list of contents included in the contents table to a display device according to an order of weight information of corresponding contents.

15. The recording medium of claim 11, where the weight information is calculated based on a rate of a total amount and a used amount of corresponding contents, and a reproduction degree is applied to the weight information while reproducing the contents,

where the preference deviation information is generated based on differences of contents included by the agent and the recording medium.

16. A non-transitory recording medium for storing a program for storing contents received from a peer-to-peer (P2P) network including a plurality of P2P nodes into a contents storage unit, the non-transitory recording medium comprising functions of:

storing a contents table including a list of contents stored in the contents storage unit and weight information for indicating a preference degree of a contents user on the respective contents

where the weight information is calculated based on a rate of a total amount and a used amount of corresponding contents, and where a reproduction degree is applied to the weight information while reproducing the contents;

storing an agent table including a list of agents sharing the weight information and preference deviation information on the respective contents of the agents,

where the preference deviation information is generated based on;

differences between values corresponding to weight information of an agent for contents and values corresponding to weight information of the recording medium for the contents, and

differences of contents included by the agent and the recording medium;

updating preference deviation information of the agent table by using the difference between weight information and the contents table, and weight information of contents possessed by the agent;
