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: 12
Claim 1
Independent Claim
151 words
A reproducing apparatus for reproducing recorded digital audio data on a disc recording medium, the digital audio data including an audio signal and a plurality of Q-channel subcodings, the reproducing apparatus comprising: data reproducing means for detecting digital audio data recorded on the disc recording medium to reproduce the audio signal and the plurality of Q-channel subcodings corresponding to the audio signal; specific information identifying means for detecting identifying information from one of the plurality of Q-channel subcodings to identify specific information imparted in the identifying information; information sorting means for sorting the specific information into character code information and editing information; decoding means for decoding the character code information into a predetermined character code; and character code train output means for editing the predetermined character code decoded by said decoding means as a displayable character code train in accordance with the editing information and outputting the displayable character code train.
Claim 2
Dependent Claim
151 words
A reproducing apparatus for reproducing recorded digital audio data on a disc recording medium, the digital audio data including an audio signal and a plurality of Q-channel subcodings, the reproducing apparatus comprising: data reproducing means for detecting digital audio data recorded on the disc recording medium to reproduce the audio signal and the plurality of Q-channel subcodings corresponding to the audio signal; specific information identifying means for detecting identifying information from one of the plurality of Q-channel subcodings to identify specific information imparted in the identifying information; information sorting means for sorting the specific information into character code information and editing information; decoding means for decoding the character code information into a predetermined character code; and character code train output means for editing the predetermined character code decoded by said decoding means as a displayable character code train in accordance with the editing information and outputting the displayable character code train.
Claim 3
Dependent Claim
18 words
A reproducing apparatus as defined in claim 1, wherein said character code information comprises basic character code information.
Claim 4
Dependent Claim
21 words
A reproducing apparatus as defined in claim 2, wherein said basic character code information consists of ASCII alphabetic characters and figures.
Claim 5
Dependent Claim
19 words
A reproducing apparatus as defined in claim 2, wherein said character code information further comprises optional character code information.
Claim 6
Dependent Claim
36 words
A reproducing apparatus as defined in claim 1, wherein said editing information comprises a selection code for identifying sections of the character code train, the sections being selectable by a user by designating said selection code.
Claim 7
Dependent Claim
94 words
A reproducing apparatus as defined in claim 1, further comprising: image information detection means for detecting and outputting image information recorded on subcoding channels other than the Q-channel of the disc recording medium in synchronization with the data reproducing means; image control information detection means for detecting image control information for the image information from a character code train decoded by the decoding means; and image output means for controlling the detected image information in response to the detected image control information and outputting displayable controlled image information with the displayable character code train.
Claim 8
Dependent Claim
73 words
A reproducing apparatus as defined in claim 6, wherein the character code train has a designated position, and wherein said displayable image information comprises information concerning an image which is displayable as a part of the displayable character code train and another displayable character code train which is outputted immediately thereafter and information concerning an image which is displayable at a designated position regardless of a designated position of the character code train.
Claim 9
Dependent Claim
27 words
A reproducing apparatus as defined in claim 1, further comprising display means for displaying the displayable character code train outputted by said character code train output means.
Claim 10
Independent Claim
123 words
A method for reproducing digital audio data recorded 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: detecting digital audio data recorded on the disc recording medium to reproduce an audio signal and a plurality of Q-channel subcodings corresponding to the audio signal; detecting identifying information from one of the Q-channel subcodings to identify specific information imparted in the identifying information; sorting the specific information into character code information and editing information; decoding the character code information into a predetermined character code; and editing the predetermined character code as a displayable character code train in accordance with the editing information and outputting the displayable character code train.
Claim 11
Independent Claim
123 words
A method for reproducing digital audio data recorded 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: detecting digital audio data recorded on the disc recording medium to reproduce an audio signal and a plurality of Q-channel subcodings corresponding to the audio signal; detecting identifying information from one of the Q-channel subcodings to identify specific information imparted in the identifying information; sorting the specific information into character code information and editing information; decoding the character code information into a predetermined character code; and editing the predetermined character code as a displayable character code train in accordance with the editing information and outputting the displayable character code train.
Claim 12
Dependent Claim
15 words
A method as defined in claim 9 further comprising, displaying the displayable character code train.
