Abstract
A display device for a Compact Disc player includes a Q-channel information detection circuit, a specific information identifying circuit, an information sorting circuit, a character code train output circuit and a display. The Q-channel information detection circuit detects Q-channel information subcoding from a signal recorded on a Compact Disc reproduced by the Compact Disc player. The specific information identifying circuit identifies specific information by means of identifying code imparted thereto. The information sorting circuit sorts the specific information provided from the specific information identifying circuit into character code information and editing information. The character code train output circuit edits the character code information in accordance with the editing information as character information and the display indicates the character information concerning contents of the Compact Disc such as the title, name of the composer or performer. The display device also includes an image information processing circuit which detects image information from Q and R to W-channels on the Compact Disc and displays mixed information of character information and image information.
