## Abstract

An information recording medium having recorded thereon picture information and/or speech information, a plurality of items consisting of the picture information and/or the speech information, and reproduction control information comprised of a plurality of lists for controlling the reproduction of the items, wherein at least a portion of the lists includes item information specifying one or more items reproduced in accordance with the lists and pointers represented by an offset from a leading end of the reproduction control information specifying another list to be linked, and wherein at least one of the lists is a first list including the item information specifying the one or more items, a plurality of pointers associated with plural lists branched according to a user selection and a plurality of region data defining regions of alternatives for menu display of the contents of the pointers according to a priority sequence.

## Claims

### Claim 1

An information recording medium having recorded thereon picture information and/or speech information, a plurality of items consisting of said picture information and/or the speech information, and reproduction control information comprised of a plurality of lists for controlling the reproduction of said items, wherein
at least a portion of the lists includes item information specifying one or more items reproduced in accordance with the lists and pointers represented by an offset from a leading end of the reproduction control information specifying another list to be linked, and wherein
at least one of the lists is a first list including the item information specifying said one or more items, a plurality of pointers associated with plural lists branched according to a user selection and a plurality of region data defining regions of alternatives for menu display of the contents of said pointers according to a priority sequence.

### Claim 2 (depends on 1)

The information recording medium as claimed in claim 1 wherein said first list includes a plurality of region data defining a plurality of rectangular regions associated with a same alternative.

### Claim 3

An information recording apparatus having recorded thereon picture information and/or speech information, a plurality of items consisting of said picture information and/or the speech information, and reproduction control information comprised of a plurality of lists for controlling the reproduction of said items, wherein
at least a portion of the lists includes item information specifying one or more items reproduced in accordance with the lists and pointers represented by an offset from a leading end of the reproduction control information specifying another list to be linked, and wherein
at least one of the lists is a second list including a plurality of said item data specifying a plurality of continuously reproduced items and a plurality of region data defining a region of an alternative for menu display of list contents.

### Claim 4 (depends on 3)

The information recording medium as claimed in claim 3 wherein said first list includes region data defining the region of said alternative at a pre-set position.

### Claim 5 (depends on 3)

The information recording medium as claimed in claim 3 wherein said second list includes region data defining the region of said alternative at an arbitrary position.

### Claim 6

An information reproducing apparatus for reproducing a picture information and/or speech information from an information recording apparatus having recorded thereon the picture information and/or the speech information, a plurality of items consisting of said picture information and/or the speech information, and reproduction control information comprised of a plurality of lists for controlling the reproduction of said items, wherein at least a portion of the lists includes item information specifying one or more items reproduced in accordance with the lists and pointers represented by an offset from a leading end of the reproduction control information specifying another list to be linked, and wherein at least one of the lists is a first list including the item information specifying said one or more items, a plurality of pointers associated with plural lists branched according to user selection and a plurality of region data defining regions of alternatives for menu display of the contents of said pointers according to a priority sequence, comprising:
reproducing means for reproducing the information recorded on said information recording medium;
menu display control means for menu display of the contents of the first list in the priority sequence based upon the region data in the first list of the reproduction control data reproduced by said reproducing means,
input means for inputting the selection information;
output means for outputting the picture information and/or the speech information reproduced by said reproducing means; and
control means for controlling the reproduction of each item by said reproducing means based upon the item information of said reproduction control information reproduced by said reproducing means, said control means switching lists interpreted on the basis of said pointers when the entry of the selection information by said input means or the reproduction of all items indicated in said first list comes to a close.

### Claim 7 (depends on 6)

The information reproducing apparatus as claimed in claim 6 wherein said menu display control means performs menu display control by a plurality of region data defining a plurality of rectangular regions associated with a same alternative in said first list.

### Claim 8

An information reproducing apparatus for reproducing picture information and/or speech information from an information recording apparatus having recorded thereon the picture information and/or the speech information, a plurality of items consisting of said picture information and/or the speech information, and reproduction control information comprised of a plurality of lists for controlling the reproduction of said items, wherein at least a portion of the lists includes item information specifying one or more items reproduced in accordance with the lists and pointers represented by an offset from a leading end of the reproduction control information specifying another list to be linked, and wherein at least one of the lists is a second list including a plurality of said item data specifying a plurality of continuously reproduced items and a plurality of region data defining a region of an alternative for menu display of the list contents, comprising:
reproducing means for reproducing the information recorded on said information recording medium;
menu display control means for menu display of the contents of the second list based upon the region data in the second list of the reproduction control data reproduced by said reproducing means;
input means for inputting the selection information;
output means for outputting the picture information and/or the speech information reproduced by said reproducing means; and
control means for controlling the reproduction of each item by said reproducing means based upon the item information of said reproduction control information reproduced by said reproducing means, said control means switching lists interpreted on the basis of said pointer when the entry of the selection information by said input means or the reproduction of all items indicated in said second list comes to a close.

### Claim 9 (depends on 8)

The information reproducing apparatus as claimed in claim 8 wherein said menu display control means performs menu display control by the region data defining the region of said alternative in said second list at a pre-set position.

### Claim 10 (depends on 8)

The information reproducing apparatus as claimed in claim 8 wherein said menu display control means performs menu display control by the region data defining the region of said alternative in said second list at a pre-set position.
