Abstract
This invention relates to a method of selectively blocking the reproduction of a video title, based on a password entered by a user, in a reproduction apparatus for playback of an optical disk on which several different versions for specific sections of a video title are recorded, such versions differing from each other in contents and rating level. The invention, e.g., checks whether a password entered is correct or not for the chosen/desired rating level; and reproduces video data corresponding to a predetermined rating level that is different than the chosen rating level when a password entered is not correct for the chosen rating level. Accordingly, this invention provides an effective way of preventing reproduction of video titles with offensive or inappropriate material by restricting opportunities of re-entering password when a password entered is not correct for the chosen rating level.
