Abstract

A data processing apparatus is disclosed which includes a reproducing element for reproducing each of a plurality of content data items a reproduction status detecting element for detecting status of each content data item being reproduced by the reproducing element a selecting element for selecting the content data item being reproduced by the reproducing element depending on the reproduction status of the content data item detected by the reproduction status detecting element a content identification data generating element for generating content identification data for identifying the content data item selected by the selecting element from the plurality of content data items and a transmitting element for transmitting to a second data processing apparatus the content identification data generated by the content identification data generating element.

Claims

1. A method collecting a tune list via an ad-hoc network, said method comprising steps of:

searching for plural portable terminals on an ad-hoc network;

detecting said plural portable terminals;

establishing ad-hoc network communication with said plural portable terminals;

receiving, from each of said plural portable terminals, a recommended tune list comprising information on a plurality of tunes recommended by a user of the respective portable terminal;

incrementing a counter for each tune included in said recommended tune lists received from said plural portable terminals; and

comparing an owned tune list with said each tune list;

extracting tunes not found in said owned list and included in said received tune lists;

genrating a collected tune list based on said extracted tunes; and

incrementing a counter for each tune included in said tune list and included in said owned list.

2. The method according to claim 1, wherein said detecting step comprises detecting said plural portable terminals in a communicable area.

3. The method according to claim 1, further comprising a step of generating a collected tune list based on said tunes included in said tune lists.

4. The method according to claim 3, further comprising a step of displaying said collected tune list.

5. The method according to claim 3, further comprising a step of reproducing a tune on said collected tune list.

6. A terminal device for collecting a tune list in ad-hoc network, said terminal comprising:

a communication unit configured to communicate with at least one terminal on ad-hoc network; and

a control unit configured to;

search for plural portable terminals on the ad-hoc network;

detect said plural portable terminals;

establish ad-hoc network communication with said plural portable terminals;

receive, from each of said plural portable terminals, a recommended tune list comprising information on a plurality of tunes recommended by a user of the respective portable terminal;

increment a counter for each tune included in said recommended tune lists received from said plural portable terminals; and

wherein said control unit is further configured to;

compare an owned list with said received tune list;

extract tunes of said received tune list not included in said owned list;

generate a collected tune list based on said extracted tunes; and

wherein said control unit is to increment a counter for each tune included in said tune list and included in said owned list.

7. The terminal device according to claim 6, wherein said control unit is further configured to detect said plural portable terminals in a communicable area of said communication unit.

8. The terminal device according to claim 6, wherein said control unit generates a collected tune list based on tunes included in said received tune list.

9. The terminal device according to claim 8, further comprising a display unit configured to display said collected tune list.

10. The terminal according to claim 8, further comprising a reproducing unit configured to reproduce a tune based included in said collected tune list.

11. A system for collecting a tune list via an ad-hoc network, said system comprising:

plural portable terminals; and

a portable terminal device configured to;

search for said plural portable terminals on an ad-hoc network;

detect said plural portable terminals;

establish ad-hoc network communication with said plural portable terminals;

receive, from each of said plural portable terminals, a recommended tune

list comprising information on a plurality of tunes recommended by a user of the respective portable terminal;

increment a counter for each tune included in said recommended tune lists received from said plural portable terminals; and

wherein said portable terminal device is further configured to;

compare an owned tune list with said each tune list;

extract tunes not found in said owned list and included in said received tune lists;

generate a collected tune list based on said extracted tunes; and

increment a counter for each tune included in said tune list and included in said owned list.

12. The system according to claim 11, wherein said portable terminal device is further configured to detect one of said plural portable terminals in a communicable area of said portable terminal.

13. The system according to claim 11, wherein said portable terminal device is further configured to generate a collected tune list based on said tunes included in said tune lists.

14. The system according to claim 13, wherein said portable terminal device is further configured to display said collected tune list.

15. The system according to claim 13, wherein said portable terminal device is further configured to reproduce a tune on said collected tune list.
