Abstract
Abstract A display device for a Compact Disc player includes a Q-channel information detection circuit (122), a specific information identifying circuit (126), an information sorting circuit (128), a character code train output circuit (132) and a display (90). The Q-channel information detection circuit (122) detects Q-channel information of a subcoding from a signal recorded on a Compact Disc reproduced by the Compact Disc player. The specific information identifying circuit (126) identifies specific information by means of identifying code imparted thereto. The information sorting circuit (128) sorts the specific information provided from the specific information identifying circuit into character code information and editing information. The character code train output circuit (132) edits the character code information in accordance with the editing information as character information and the display (90) 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.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
189 words
A display device for a Compact Disc player comprising: audio signal reproduction means for detecting digital audio data recorded on a Compact Disc and reproducing an audio signal corresponding to the digital audio data; Q-channel information detection means for detecting and outputting Q-channel information of subcoding data recorded on the Compact Disc in parallel with detection and reproduction by the audio signal reproduction means; specific information identifying means for identifying specific information consisting of a character code for corresponding contents of the audio signal from an output of the Q-channel- information detection means by means of an identifying code imparted to the specific information and outputting indentified specific information, the specific information having character code information and editing information; information sorting means for sorting the identified specific information into the character code information and the editing information; character code train output means for editing the character code information provided by the information sorting means as a displayable character code train in accordance with the editing information and outputting the character code train; and display means for displaying the character code train provided by the character code train output means.
Claim 2
Dependent Claim
