Abstract:
A digital movie screening system in which a movie subtitle can easily be used with protection of the copyright on the subtitle. A character information generating apparatus includes an encryption unit to encrypt a font file including data for displaying characters in a specific font, and a character information file generator to generate a character information file including a main file describing therein text data representing the content of characters to be displayed on a display unit and control data for displaying the characters and a font file encrypted by the encryption unit. The character information file generator also describes, in the main file, information on whether a font file indicated with a pointer, if any, described in the main file is an encrypted file.
