ABSTRACT:
An information recording medium is recorded with a plurality of data groups, each including at least one of video information and audio information and a reproduction permission level by which a reproduction of at least one of the video information and the audio information is permitted; and a reproduction management information including the reproduction permission range information for prescribing the range of the reproduction permission level for the data group which reproduction is permitted. When the reproduction permission level and the reproduction management information are selected, the range of the reproduction permission level of the data groups which reproduction are permitted is detected on the basis of the reproduction permission level selected. Then, the data group is reproduced when the reproduction permission level of the selected data group is included in the range of the reproduction permission level detected.
