Abstract:
An information processing device, an information processing method, a recording medium, and a program capable of recording a user operation history in a small capacity. A state transition detection section (52) of a CPU (21) detects transition of the content state. A metric value setting section (53) of the CPU (21) sets a reference value as a metric value. A metric value conversion section (54) of the CPU (21) converts the transition of the content state detected by the state transition detection section (52) into a metric value. A content operation history database section (61) of an HDD (26) accumulates and records the metric values converted by the metric value conversion section (54). The present invention can be applied to a hard disc recorder.
