Abstract

The present invention facilitates operations of updating, altering and/or otherwise recomposing the reproduction list of contents data prepared according to the frequency of reproduction, the priority of reproduction, the preference of the user and so on. There is provided a contents data reproduction apparatus for reproducing contents data, which includes a detecting section that detects the external force, a weighting information generating section that generates weighting information, a memory section that stores the weighting information, a reproduction control section that composes a reproduction list of the contents data, a reproduction section that reads out the contents data and reproducing them, and a display section that visibly displays the reproduction list, the reproduction control section recomposing the reproduction list of the contents data, referring to the weighting information, according to the outcome of detection of the detecting section and visibly displaying the reproduction list on the display section.

Claims

1. A contents data reproduction apparatus for reproducing contents data from a contained recording medium or a removably fitted recording medium storing contents data, the apparatus comprising:

a detecting section that detects the external force applied to the contents data reproduction apparatus;

weighting information generating means for generating weighting information including contents information relating to the contents data stored in the recording medium and information on the use of the contents data and indicating the reproduction priority for the contents data;

a memory section that stores the weighting information generated for the contents data;

a reproduction control section that composes a reproduction list of the contents data according to the weighting information stored in the memory section;

a reproduction section that reads out the contents data stored in the recording medium and reproducing them according to the reproduction list; and

a display section that visibly displays the reproduction list;

the reproduction control section recomposing the reproduction list of the contents data, referring to the weighting information, according to the outcome of detection of the detecting section and visibly displaying the reproduction list on the display section.

2. The apparatus according to claim 1, wherein the reproduction list has a hierarchical structure and contents data having more heavily weighted information are arranged in upper layers.

3. The apparatus according to claim 1, wherein the reproduction control section introduces random values unrelated to the weighting information depending on the outcome of detection of the detecting section and recomposes the reproduction list according to the random values.

4. The apparatus according to claim 3, wherein the reproduction control section updates the recomposed reproduction list by changing the random values as a function of the elapsed time since the recomposition and restores the reproduction list according to the original weighting information after a predetermined period of time.

5. The apparatus according to claim 4, wherein the reproduction control section so defines the time period until restoration that it is shorter for contents data arranged on upper lines of the reproduction list according to the original weighting information.

6. The apparatus according to claim 1, wherein the weighting information generating means changes the weighting information by a predetermined value and uses it as new weighting information each time when the entire contents data have been reproduced.

7. The apparatus according to claim 1, wherein the weighting information generating means changes the weighting information by a predetermined value and uses it as new weighting information each time when a part of the contents data has been reproduced.

8. The apparatus according to claim 1, wherein the weighting information generating means changes the weighting information as a function of the time period during which external force is applied or the intensity of external force as detected by the detecting section by a predetermined value and uses it as new weighting information.

9. A contents data reproduction method that reproduces contents data by a contents data reproduction apparatus for reproducing contents data from a contained recording medium or removably fitted recording medium storing contents data, the method comprising:

a step of detecting the duration of application of external force or the intensity of external force by means of a sensor for detecting the external force applied to a contents data reproduction apparatus;

a weighting information generating step of generating weighting information including contents information relating to the contents data stored in a recording medium and information on the use of the contents data and indicating the reproduction priority for the contents data;

a reproduction control step of composing a reproduction list for the contents data according to the weighting information generated for the contents data and stored in a memory storing the contents data;

a reproduction step of reading out and reproducing the contents data stored in the recording medium according to the reproduction list; and

a display step of visibly displaying the reproduction list on a display section;

the reproduction control step being adapted to recompose the reproduction list of the contents data, referring to the weighting information, according to the outcome of detection of the sensor.

10. The method according to claim 9, wherein the reproduction control step is adapted to irregularly recompose the reproduction list according to the outcome of detection of the sensor.

11. A contents data reproduction apparatus for reproducing contents data from a contained recording medium or a removably fitted recording medium storing contents data, the apparatus comprising:

a detecting section that detects the external force applied to the contents data reproduction apparatus;

a weighting information generating section that generates weighting information including contents information relating to the contents data stored in the recording medium and information on the use of the contents data and indicating the reproduction priority for the contents data;

a memory section that stores the weighting information generated for the contents data;

a reproduction control section that composes a reproduction list of the contents data according to the weighting information stored in the memory section;

a reproduction section that reads out the contents data stored in the recording medium and reproducing them according to the reproduction list; and

a display section that visibly displays the reproduction list;

the reproduction control section recomposing the reproduction list of the contents data, referring to the weighting information, according to the outcome of detection of the detecting section and visibly displaying the reproduction list on the display section.
