Abstract

A storage medium storing an interactive graphics stream providing a menu having a variety of screen conversion effects, and a reproducing apparatus and a reproducing method, thereof. The storage medium includes: video data; and graphics data displaying a menu overlaid on an image displayed based on the video data, wherein the graphics data includes a plurality of menu pages, and each of the plurality of menu pages includes control information to determine whether to execute conversion effect information defining a screen conversion effect and execute a screen conversion effect defined when a conversion between the plurality of menu pages occurs. Each of the plurality of menu pages includes a plurality of screen conversion effect information items applied when a menu page conversion occurs.

Claims

1. A storage medium storing multimedia information for use with a recording and/or reproducing apparatus, the storage medium comprising:

video data; and

graphics data used by the apparatus displaying a menu overlaid on an image displayed on the basis of the video data,

wherein the graphics data includes a plurality of menu pages, and each of the plurality of menu pages includes conversion effect information used by the apparatus for defining a screen conversion effect and control information used by the apparatus to execute a first screen conversion effect when a first conversion between the plurality of menu pages occurs and to execute a second screen conversion effect when a second conversion between the plurality of menu pages occurs.

2. The storage medium of claim 1, wherein the control information is included in button information contained in each of the plurality of menu pages.

3. The storage medium of claim 2, wherein the button information includes navigation commands to be executed when a button contained in each of the plurality of menu pages is selected.

4. The storage medium of claim 1, wherein each of the plurality of menu pages includes one or more items of the conversion effect information.

5. The storage medium of claim 4, wherein each of the plurality of menu pages designates default conversion effect information in addition to the one or more items of the conversion effect information, when a menu page conversion occurs.

6. The storage medium of claim 1, wherein the conversion effect information includes a screen conversion effect to be executed when each of the plurality of menu pages appears on a screen and a screen conversion effect to be executed when each of the plurality of menu pages disappears from the screen.

7. The storage medium of claim 1, wherein the control information includes navigation commands, and the navigation commands include an identifier of a menu page to which a navigation command is applied, and information designating effect information to appear or disappear from the screen, among the conversion effect information.

8. The storage medium of claim 7, wherein each of the navigation commands further include an identifier of the corresponding item of the conversion effect information.

9. A reproducing apparatus, comprising:

a video decoder which decodes video data; and

a graphics decoder which decodes graphics data displaying a menu overlaid on an image displayed on the basis of the video data, the graphics decoder reading conversion effect information included in a plurality of menu pages and control information, and a controller to determine whether to execute a first screen conversion effect when a first conversion between the plurality of menu pages occurs, to execute a second screen conversion effect between the plurality of menu pages and to display a menu page on a screen based on the conversion effect information and the control information.

10. The reproducing apparatus of claim 9, wherein the control information is included in button information contained in the plurality of menu pages, and the graphics decoder converts the menu page into another menu page based on the control information, by selectively generating the screen conversion effect when a button is pressed.

11. A reproducing method, comprising:

reading graphics data including a plurality of menu pages providing a menu screen;

decoding the graphics data and displaying a menu page on a screen; and

when a menu page conversion is requested, reading conversion effect information defined in each of the plurality of menu pages and control information to determine whether to execute a screen conversion effect defined when a conversion between the plurality of menu pages occurs, and displaying the menu page on the screen based on the conversion effect information and the control information.

12. The reproducing method of claim 11, wherein the control information is included in button information contained in the plurality of menu pages, and the menu page is converted into another menu page based on the control information, by generating or not the screen conversion effect when a button is pressed.

17. A computer readable medium encoded with processing instructions performing the method of claim 11 as performed by a computer.

18. The computer readable medium of claim 17, wherein the control information is included in button information contained in the plurality of menu pages, and the menu page is converted into another menu page based on the control information, by generating or not the screen conversion effect when a button is pressed.

13. A storage medium storing multimedia information for use with a recording and/or reproducing apparatus, the storage medium comprising:

video data for displaying a menu overlaid on an image displayed on the basis of the video data data; and

graphics data, the graphics data comprising;

at least one menu page used by the apparatus for implementing a menu screen,

the at least one menu page including in-effect and out-effect information to be executed by the apparatus when the at least one menu page appears or disappears on the menu screen and the at least one menu page having no navigation command to control a screen conversion effect;

a plurality of conversion effect information items executed by the apparatus by a navigation command to control the screen conversion effect when a menu page conversion occurs; and

graphical user interface information containing the navigation command, the navigation command allowing movement to another of the at least one menu page, wherein the navigation command is used by the apparatus to determine whether to execute a screen conversion effect information of the in-effect information and the out-effect information and to differentiate between and execute an indicated one of the plurality of conversion effect information items.

14. The storage medium of claim 13, wherein the navigation command contains enable and disable commands to determine whether to execute the in-effect information and the out-effect information.

15. The storage medium of claim 13, wherein each of the plurality of menu pages includes one or more pieces of the conversion effect information.

16. The storage medium of claim 13, wherein the navigation command includes an identifier of a menu page and information designating effect information to appear or disappear from the screen.

19. A storage medium storing multimedia information for use with a recording and/or reproducing apparatus, the storage medium including graphics data, the graphics data comprising:

a plurality of menu pages defining a variety of screen conversion effects, wherein each menu page includes effect information to be executed when a menu page appears or disappears from the menu screen, conversion effect definition information items and a plurality of button information items containing a navigation command to move to another menu page, each of the conversion effect definition information items being associated with a corresponding button information item such that the apparatus selects the corresponding conversion effect definition information item when the corresponding button information item is selected.
