INFORMATION RECORDING MEDIUM AND REPRODUCTION CONTROL METHOD

摘要

An information recording medium (104) where a first content and a program are recorded. A player (1) has first storage means (221) storing a set value, executing means (206) for executing a program, and a second storage means (222) from/on which the executing means (206) can read/write information. The program allows the executing means to execute a first storage step (S803) of writing the set value stored in the first storage means (221) into the second storage means (222), a comparing step (S900) of comparing the set value stored in the first storage means (221) with the set value previously written in the second storage means (222), and a control step (S920) for inhibiting the player to play the first content when the result of the comparison shows that the set value stored in the first storage means (221) is different from the set value previously written in the second storage means (222).
