ABSTRACT:
Digital sound data is encrypted and recorded in a recording medium200. Information212required for decoding the encrypted digital sound data220is recorded in a program211for controlling the reproduction of sound data separately from the digital sound data220. This can prevent PCM sound data recorded in the recording medium as a part of a content, from being reproduced separately from the content.
