Abstract

An information storage medium on which a plurality of titles are recorded, and a reproducing apparatus and method thereof. The information storage medium includes a plurality of titles which are reproduced as motion pictures and a plurality of units of attribute information that correspond to the titles and indicate whether a user can control a title to be reproduced. Therefore, efficient navigation can be ensured and the titles can be reproduced as a manufacturer of the information storage medium has planned.

Claims

1. An information storage medium, comprising:

at least one title which is reproduced as a motion picture; and

at least one unit of attribute information, which corresponds to the at least one title and indicates whether a user is able to control one of the at least one title to be reproduced, wherein the attribute information includes access type information which represents each title as “

normal title”

if the title is searchable by a user operation and represents each title as “

hidden title”

if the title is not searchable by the user operation, and the access type information that represents the title as “

hidden title”

further contains information that indicates whether a title number of the title is displayed.

2. The information storage medium of claim 1, wherein the title is displayed when a value of the access type information is 0, and the title is not displayed when the value of the access type information is 1.

3. A reproducing apparatus, comprising:

a reader which reads data comprising at least one title to be reproduced as a motion picture and at least one unit of title information that corresponds to the at least one title from an information storage medium;

a buffer which buffers the data read by the reader; and

a decoder which interprets the title information to indicate an entry point of the at least one title and reproduces the at least one title,

wherein the decoder interprets attribute information contained in the title information to indicate whether a user is able control the title to be reproduced, the decoder determines that the user operation to the title is permitted if access type information which acts as the attribute information represents the title as “

normal title”

, and the user operation to the title is not permitted if the access type information represents the title as “

hidden title”

, and if the access type information represents the title as “

hidden title”

, and the decoder displays a title number of the title when the title is reproduced according to information which is contained in the attribute information that indicates whether the title number of the title is displayed.

4. The reproducing apparatus of claim 3, wherein the title is displayed when a value of the access type information is 0, and the title is not displayed when the value of the access type information is 1.

5. A reproducing apparatus using an information storage medium, comprising:

a reader which reads titles and title information corresponding to the respective titles from the information storage medium;

a buffer which buffers the titles and title information; and

a decoder which selectively decodes the titles based on the title information and attribute information in the title information designating user control of the selected decoded titles, wherein the attribute information further comprises number display information indicating whether a title number of one of the selected decoded titles is to be reproduced.
