Embodiment Construction

[0074] Next, embodiments of the present invention will be described in the following order.

[0075] 1. UMD video standard

[0076] 2. Player model according to UMD video standard

[0077] 3. The event model of the movie player

[0078] 4. Movie player object

[0079] 5. Examples of script programs

[0080] 6. File management structure

[0081] 7. Disc playback device

[0082] 8. Control of user operations

[0083] 1. UMD video standard

[0084] For easy understanding of the present invention, a system according to an embodiment of the present invention will be described. According to an embodiment of the present invention, a player model is described using a scripting language called ECMA script. ECMA Script is a cross-platform scripting language based on JavaScript (registered trademark) and standardized by the European Computer Manufacturers Association (ECMA). ECMA scripts have higher compatibility with HTML documents. Furthermore, since ECMA script allows the de...

Abstract

It is possible to easily limit a user operation when reproducing a content. A limit mode for limit the user operation to control reproduction of a content is set in advance and a value indicating the limit mode is recorded for each play list as attribute information in the disc. A player generates a table based on the limit mode for each play list during reproduction of the disc and subjects the control command for controlling reproduction of the content generated by the user operation to filtering by the command filter by referencing the table. The limit mode is, for example, a mode in which the play list is should be reproduced at a predetermined speed such as the normal speed from the head and a mode in which jump of the play list during reproduction is inhibited. Thus, it is possible to reduce the load of verification for the user operation limit at the content creation side and the verification load of the operation at the player side.

Description

technical field [0001] The present invention relates to a reproducing apparatus, a reproducing method, a reproducing program, a recording medium, and a data structure which allow a user to interactively operate a program recorded on a large-capacity recording medium and allow predetermined user operations to be restricted easily. Background technique [0002] As a recording medium that can be randomly accessed and attached / detached, a long time has passed since the appearance of the DVD (Digital Versatile Disc). In recent years, disc-shaped recording media having a larger storage capacity and being smaller and more convenient than DVDs have been developed. [0003] In the conventional reproduction-only DVD-Video standard, interactive functions are realized using button images and the like appearing on menu screens. For example, when a movie is being reproduced from a DVD-Video disc, a menu screen is invoked using a remote controller or the like. By selecting the button ima...
