Abstract
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.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
133 words
A recording apparatus for recording digital audio data on a disc recording medium, the digital audio data including an audio signal and a plurality of Q-channel subcodings, the recording apparatus comprising: data recording means for recording digital audio data on the disc recording medium that can be used to reproduce the audio signal and the plurality of Q-channel subcodings corresponding to the audio signal; specific information identifying means for recording identifying information into one of the plurality of Q-channel subcodings to identify a displayable character code train imparted into the plurality of Q-channels subcodings as specific information; information sorting means for sorting the specific information into character code information and editing information for recording; and recording means for recording the character code information and the editing information into the plurality of Q-channel subcodings.
Claim 2
Dependent Claim
133 words
A recording apparatus for recording digital audio data on a disc recording medium, the digital audio data including an audio signal and a plurality of Q-channel subcodings, the recording apparatus comprising: data recording means for recording digital audio data on the disc recording medium that can be used to reproduce the audio signal and the plurality of Q-channel subcodings corresponding to the audio signal; specific information identifying means for recording identifying information into one of the plurality of Q-channel subcodings to identify a displayable character code train imparted into the plurality of Q-channels subcodings as specific information; information sorting means for sorting the specific information into character code information and editing information for recording; and recording means for recording the character code information and the editing information into the plurality of Q-channel subcodings.
Claim 3
Dependent Claim
18 words

Claim 9
Independent Claim
109 words
A method for recording digital audio data on a disc recording medium, the digital audio data including an audio signal and a plurality of Q-channel subcodings, the method comprising the steps of: recording digital audio data on the disc recording medium to reproduce an audio signal and a plurality of Q-channel subcodings corresponding to the audio signal; recording identifying information into the plurality of Q-channel subcodings to identify a displayable character code train as specific information imparted into the plurality of Q-channel subcodings; sorting the specific information into character code information and editing information; and recording the character code information and editing information into the plurality of Q-channel subcodings.
Claim 10
Independent Claim
109 words
A method for recording digital audio data on a disc recording medium, the digital audio data including an audio signal and a plurality of Q-channel subcodings, the method comprising the steps of: recording digital audio data on the disc recording medium to reproduce an audio signal and a plurality of Q-channel subcodings corresponding to the audio signal; recording identifying information into the plurality of Q-channel subcodings to identify a displayable character code train as specific information imparted into the plurality of Q-channel subcodings; sorting the specific information into character code information and editing information; and recording the character code information and editing information into the plurality of Q-channel subcodings.
