<p>The recording medium has discrimination data (E-bit) indicating whether or not content data has been encrypted and recorded with copy control information data (CCI data) into the content data. If the content data whose copying is not permitted is reproduced, the discrimination data (E-bit) is read out from the content data, and then the read discrimination data (E-bit) is compared with encrypted state of the reproduced content data. If the discrimination data (E-bit) shows a state different from the current encrypted state of the content data, the apparatus prohibits the reproduction of the content data. <IMAGE></p> |
