Abstract

A data processing apparatus capable of recording the user'"'"'s operation histories in a small capacity, a data processing method, a recording medium and a program. A state transition detector unit 52 in a CPU 21 detects the transition of a state of contents. A metric value-setting unit in the CPU 21 sets a reference value as a metric value. A metric value conversion unit 54 in the CPU 21 converts, into a metric value, the transition of a state of contents detected by the state transition detector unit 52. A contents operation history database 61 in an HDD 26 accumulates the metric values converted by the metric value conversion unit 54 and stores them. The invention can be applied to a hard disk recorder.

Claims

1. A data processing apparatus characterized by comprising:

contents ID-obtaining mechanism for obtaining IDs of the contents that are obtained;

detector for detecting the transition of the state of contents;

converter for converting the transition of the state of contents detected by the detector into a metric value; and

recording mechanism for recording the metric value converted by the converter together with the IDs of the contents.

2. A data processing apparatus according to claim 1, characterized in that the recording mechanism accumulates the metric values to record the operation history of the contents.

3. A data processing apparatus according to claim 1, characterized by further comprising user ID-obtaining mechanism for obtaining a user ID, wherein the recording mechanism further records the user ID.

4. A data processing method for a data processing apparatus that reproduces the recorded contents, characterized by including the steps of:

obtaining IDs of the contents that are obtained;

detecting the transition of the state of contents;

converting the transition of the state of contents detected in the step of detection into a metric value; and

recording the metric value converted in the step of conversion together with the IDs of the contents.

5. A recording medium recording a computer-readable program for reproducing the recorded contents, the program characterized by including the steps of:

obtaining IDs of the contents that are obtained;

detecting the transition of the state of contents;

converting the transition of the state of contents detected in the step of detection into a metric value; and

recording the metric value converted in the step of conversion together with the IDs of the contents.

6. A program for reproducing the recorded contents, characterized by executing the steps of:

obtaining IDs of the contents that are obtained;

detecting the transition of the state of contents;

converting the transition of the state of contents detected in the step of detection into a metric value; and

recording the metric value converted in the step of conversion together with the IDs of the contents.
