Abstract
Abstract At least one group of division screen data is inserted and recorded, together with music data groups, on a disc in each of a plurality of groups of music data which are divided by Q channel data in a subcode in a CD format, and one group of music data group is successively selected and read from the disc. The division screen data group contained in the read music data group is written into the corresponding division screen storage regions, and the written data are read from a total storage region composed of all the division screen storage regions in a prescribed reading sequence, thus providing an image signal representing a total screen composed of division screens indicated by the divided screen data group. Accordingly, a displayed image can be formed or varied to indicate the progress or sequence of audio information as it is progressively reproduced or played back.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
106 words
A music and graphics information storage and reproducing system comprising: storage means for storing therein an information signal including a plurality of music data groups and a plurality of graphics data groups distributed along the same time axis as said music data groups, said graphics data groups including a first type of divided screen data group and at least one separate second type of divided screen data group defining a complement of said first type of divided screen data group to form a single-frame image; and means responsive to both said types of divided screen data groups for providing an output signal representing said single-frame image.
Claim 2
Dependent Claim
106 words
A music and graphics information storage and reproducing system comprising: storage means for storing therein an information signal including a plurality of music data groups and a plurality of graphics data groups distributed along the same time axis as said music data groups, said graphics data groups including a first type of divided screen data group and at least one separate second type of divided screen data group defining a complement of said first type of divided screen data group to form a single-frame image; and means responsive to both said types of divided screen data groups for providing an output signal representing said single-frame image.
Claim 3
Dependent Claim
26 words
A system as claimed in claim 1, wherein said music data groups are stored in said storage means as a main code in a CD format.
Claim 4
Dependent Claim
25 words
A system as claimed in claim 2, wherein said graphics data groups are stored in said storage means as a subcode in said CD format.
Claim 5
Dependent Claim
130 words
A system as claimed in claim 1, wherein said means for providing an output signal comprises: means for selectively reading at least one of said music data groups from said storage means for providing a music output; memory means; means for reading at least one of said first type of divided screen data group and at least one of said second type of divided screen data group from said storage means for separate storage in said memory means; and means for sequentially reading said first type of divided screen data group and said second type of divided screen data group, respectively, from said memory means for providing as said output signal, a single-frame image signal comprising said first and second types of data groups in correlation with said music output.
Claim 6
Dependent Claim
40 words
A system as claimed in claim 1, wherein said means responsive includes means for providing at least a respective one of said plurality of music data groups in correlation with a display of said single-frame image on a single screen.
Claim 7
Independent Claim
103 words
A method of storing and reproducing music and graphics information comprising the steps of: recording an information signal including a plurality of music data groups and a plurality of graphics data groups distributed along the same time axis as said music data groups, said graphics data groups including a first type of divided screen data group and at least one separate second type of divided screen data group defining a complement of said first type of divided screen data group to form a single-frame image; and reading both said types of divided screen data groups for providing an output representing said single-frame image.
Claim 8
Independent Claim
103 words
A method of storing and reproducing music and graphics information comprising the steps of: recording an information signal including a plurality of music data groups and a plurality of graphics data groups distributed along the same time axis as said music data groups, said graphics data groups including a first type of divided screen data group and at least one separate second type of divided screen data group defining a complement of said first type of divided screen data group to form a single-frame image; and reading both said types of divided screen data groups for providing an output representing said single-frame image.
Claim 9
Dependent Claim
23 words
A method as claimed in claim 6, wherein said music data groups are recorded as a main code in a standard CD format.
Claim 10
Dependent Claim
21 words
A method as claimed in claim 7, wherein said graphics data groups are recorded as a subcode in said CD format.
Claim 11
Dependent Claim
66 words
A method as claimed in claim 6, wherein said reading step comprises: selectively reading successive ones of said music and graphics data groups; writing said graphics data read from said successive ones of said graphics data groups into corresponding regions of a memory; and sequentially reading both said types of divided screen data groups from said memory to form an image signal representing a single-frame image.
Claim 12
Dependent Claim
38 words
A method as claimed in claim 6, wherein said reading step includes reading and providing at least a respective one of said plurality of music data groups in correlation with displaying said single-frame image on a single screen.
