First Claim
1. A Compact Disc player capable of displaying character information comprising:
- reproducing means for reading out digital data recorded on a compact disc, the digital data including digital audio data and specific information;
specific information identifying means for identifying specific information from digital data read out by said reproducing means, the specific information having character code information and character modifying information, the character modifying information being included in an escape sequence of a Q-channel information;
the specific information identifying means comprising converting means for converting the character code information into character information, and modifying means for modifying character information converted by said converting means on the basis of the character modifying information; and
display means for displaying character information modified by said character modifying means.

Abstract
A Compact Disc player having a display device includes a reproducing circuit for reading out digital data which includes digital audio data and specific information recorded on a Compact Disc, a specific information identifying circuit for identifying both character code information and modifying information from the specific information, a character decoder for decoding the identified character code information to character information on the basis of code converting information such as ASCII character code information, and a modifying circuit for modifying the decoded character information on the basis of the identified modifying information. Thus, the Compact Disc player can display the character information modified by the modifying information on the display device. The Compact Disc player is also capable of displaying image information on the basis of image contour co-ordinates data recorded in a subcoding area of a Compact Disc.
