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 portable terminal device comprising:

a communication unit configured to transmit to another portable terminal device a list which shows a plurality of content data items including said selected recommendation content data item;

wherein the reproduction status of said recommendation content data item is selected from a group comprising the recommendation content data item having been reproduced by the reproduction unit for a predetermined period of time, a particular portion of the recommendation content data item having been reproduced by the reproduction unit, the entirety of the recommendation content data item having been reproduced by the reproduction unit, the recommendation content data item having been reproduced by the reproduction unit after being rewound, the recommendation content data item having been reproduced by the reproduction unit during a particular time of day, the recommendation content data item having been reproduced by the reproduction unit a predetermined number of times, and the recommendation content data item having been designated by a user.

2. The portable terminal device according to claim 1, wherein said communication unit transmits, together with said list, the recommendation content data item on said list.

3. The portable terminal device according to claim 1, wherein said control unit detects the recommendation content data item as having been reproduced longer than a predetermined time period.

4. The portable terminal device according to claim 1, wherein said control unit detects a specific part of the recommendation content data item being reproduced.

5. The portable terminal device according to claim 1, wherein said control unit detects the recommendation content data item as having been reproduced from beginning to end.

6. The portable terminal device according to claim 1, wherein said control unit detects, during reproduction of the recommendation content data item, the number of times said recommendation content data item has been reproduced from the beginning thereof.

7. The portable terminal device according to claim 1, wherein said control unit searches for another portable terminal device, and said communication unit transmits said list to said another portable terminal device, when said another portable terminal device has been detected by said control unit.

8. The portable terminal device according to claim 1, wherein said communication unit communicates with another portable terminal device via an ad hoc network.

9. The portable terminal device according to claim 8, wherein said control unit transfers said list to a plurality of portable terminal devices on said ad hoc network.

10. The portable terminal device according to claim 1, wherein said recommendation content data item is a tune, said control unit transfers said selected tune from a tune list to a recommended tune list, and said communication unit transmits said recommended tune list to said second portable terminal device.

11. A data processing method for use with a portable terminal device, the method comprising steps of:

reproducing a plurality of content data items;

detecting a reproduction status of each content data item when said each content data item is being reproduced;

selecting a recommendation content data item being reproduced from said plurality of content data items depending on a detected reproduction status of said recommended content data item; and

transmitting a list which shows a plurality of content data items including said selected recommended content data item to a second portable terminal device;

wherein the reproduction status of said recommendation content data item is selected from a group comprising the recommendation content data item having been reproduced by the reproduction unit for a predetermined period of time, a particular portion of the recommendation content data item having been reproduced by the reproduction unit, the entirety of the recommendation content data item having been reproduced by the reproduction unit, the recommendation content data item having been reproduced by the reproduction unit after being rewound, the recommendation content data item having been reproduced by the reproduction unit during a particular time of day, the recommendation content data item having been reproduced by the reproduction unit a predetermined number of times, and the recommendation content data item having been designated by a user.

12. The data processing method according to claim 11, wherein the step of transmitting further comprises transmitting, together with said list, the recommendation content data item on said list.

13. The data processing method according to claim 11, wherein said step of detecting further comprises detecting the content data item having been reproduced longer than a predetermined time period.

14. The data processing method according to claim 11, wherein said step of detecting further comprises detecting a specific part of the recommendation content data item being reproduced.

15. The data processing method according to claim 11, wherein said step of detecting further comprises detecting the recommendation content data item as having been reproduced from beginning to end.
