Claim 10

An information reproducing apparatus according to claim 6, wherein said reproducing means comprises display means on which to display image data in any one of two ways in accordance with the address information about the image data recorded in each block, one of said two ways being that in which said image data are to be displayed continuously, the other of said two ways being that in which said image data are to be displayed selectively.

Claim 11

An information reproducing apparatus according to claim 6, wherein said reproducing means comprises means for nullifying the continuous reproduction of the text data contained in said reproduction data when said discriminating means finds said reproduction data to be those data that are to be reproduced continuously.

Claim 12

A combination of an information recording medium and an apparatus for reproducing the information recording medium, wherein on the information recording medium are recorded, in units of blocks, reproduction data, including voice data, image data and text data as well as reproduction data management information including address information and continuous reproduction information, the address information being organized in a layered structure to designate addresses on the recording medium at which the reproduction data are stored, the continuous reproduction information specifying any one of two ways in which to reproduce the reproduction data, a first way being that in which the reproduction data are to be reproduced continuously, a second way being that in which the reproduction data are to be reproduced selectively, and wherein the information reproducing apparatus includes: reproducing means for reproducing data recorded on the information recording medium; display means for displaying image data; input means for entering commands from a user of the information reproducing apparatus; a central processing unit (CPU); a read only memory (ROM) connected to the CPU; a random access memory (RAM) connected to the CPU; a video random access memory (VRAM) connected to the display means for storing image data to be displayed by the display means; an input/output (I/O) means for connecting the reproducing means the display means, the input means, and the CPU together, wherein the CPU controls the operations of the reproducing means, the display means, the ROM and the RAM; and wherein the CPU discriminates the continuous reproduction information in each block and controls the reproducing means to reproduce the reproduction data in units of blocks and in any one of the two ways in which to reproduce the reproduction data depending on the result of the discrimination by the CPU.

Claim 13

A combination of an information recording medium and an apparatus for reproducing the information recording medium, wherein on the information recording medium are recorded, in units of blocks, reproduction data, including voice data, image data and text data as well as reproduction data management information including address information and continuous reproduction information, the address information being organized in a layered structure to designate addresses on the recording medium at which the reproduction data are stored, the continuous reproduction information specifying any one of two ways in which to reproduce the reproduction data, a first way being that in which the reproduction data are to be reproduced continuously, a second way being that in which the reproduction data are to be reproduced selectively, and wherein the information reproducing apparatus includes: reproducing means for reproducing data recorded on the information recording medium; display means for displaying image data; input means for entering commands from a user of the information reproducing apparatus; a central processing unit (CPU); a read only memory (ROM) connected to the CPU; a random access memory (RAM) connected to the CPU; a video random access memory (VRAM) connected to the display means for storing image data to be displayed by the display means; an input/output (I/O) means for connecting the reproducing means the display means, the input means, and the CPU together, wherein the CPU controls the operations of the reproducing means, the display means, the ROM and the RAM; and wherein the CPU discriminates the continuous reproduction information in each block and controls the reproducing means to reproduce the reproduction data in units of blocks and in any one of the two ways in which to reproduce the reproduction data depending on the result of the discrimination by the CPU.

Claim 14

The combination according to claim 10, wherein the CPU, upon determining from the continuous reproduction information of a given block of data in a series of blocks of data that the reproduction data of the given block is to be reproduced in the second way, causes the reproducing means to reproduce the given block and the display means to display image data of the given block and then awaits a further command to be input via the input means by a user of the combination.

Claim 15

The combination according to claim 10, wherein the CPU, upon determining from the continuous reproduction information of a given block of data in a series of blocks of data that the reproduction data of the given block is to be reproduced in the first way, causes the reproducing means to reproduce the given block and the display means to display image data of the given block and then, automatically, causes the reproducing means to reproduce a next given block as designated by address information contained in the given block, and the display means to display image data of the next given block and then to continually repeat this process for each next given block whose address is designated by the currently reproduced given block until the CPU determines from the continuous reproduction information of the currently reproduced given block that the information contained therein is to be reproduced in the second way, whereupon the CPU ceases reproduction of blocks of data from the recording medium and awaits a further command to be input via the input means by a user of the combination.
