Abstract

A method of controlling the operations and display mode of an optical disc player between a user agent mode and a video playback mode. The method comprises reading a program stored on a local optical disc that may include a function that specifies the video playback mode as the operations mode for the optical disc player. In the video playback mode, in one case a user agent menu is displayed while displaying video menu, while in another case, video menu can be displayed while running the user agent menu in the background. The program may include a second function that changes the operations mode of the optical disc player to user agent mode where the user agent menu is displayed in the foreground of the displaying device. In one embodiment, these functions change the operations mode while also disabling the user control interface to prevent a user from changing the operations mode. In another embodiment, these functions change the operations mode of the optical disc player without disabling the user control interface, thereby allowing a user to change the operations mode of the optical disc player.

Claims

1. A method of controlling an operations and display mode of an optical disc player between a user agent mode and a video playback mode, comprising:

reading an interactive program stored on a local optical disc, wherein said interactive program includes a first function that specifies said video playback mode;

changing said operations mode of said optical disc player to said specified mode;

displaying a video menu in a foreground of a displaying device; and

running a user agent menu in a background of said displaying device.

2. The method of claim 1, wherein said first function further disables a user control interface to prevent a user from changing said operations mode of said optical disc player.

3. The method of claim 1, wherein said first function does not disable a user control interface, allowing a user to change said operations mode of said optical disc player.

4. The method of claim 1, wherein said interactive program further includes a second function that enables a user control interface to allow a user to change said operations mode of said optical disc player.

5. The method of claim 1, wherein said optical disc player comprises a dedicated optical disc player.

6. The method of claim 1, wherein said optical disc player is embodied in a computer system.

7. The method of claim 1, further comprising:

changing said operations mode of said optical disc player to said user agent mode; and

displaying said user agent menu in said foreground of said displaying device.

8. An optical disc for controlling an operations and display mode of an optical disc player between a user agent program and a video playback mode, comprising:

an interactive program including a first function that causes said optical disc player to change said operations mode to said video playback mode, wherein a video menu is displayed in a foreground of displaying device and a user agent menu is running in a background of said displaying device;

said interactive program further including a second function that causes said operations mode to change from said video playback mode to said user agent mode, wherein said user agent menu is displayed in said foreground of said displaying device.

9. The optical disc of claim 8, wherein said first function further disables a user control interface of said optical disc player to prevent a user from changing said operations mode of said optical disc player.

10. The optical disc of claim 8, wherein said first function does not disable a user control interface of said optical disc player, allowing a user to change said operations mode of said optical disc player.

11. The optical disc of claim 8, wherein said interactive program further includes a third function that enables a user control interface of said optical disc player to allow a user to change said operations mode of said optical disc player.

12. The optical disc of claim 8, wherein said optical disc comprises a digital versatile disc.

13. The optical disc of claim 8, wherein said optical disc player comprises a dedicated optical disc player.

14. The optical disc of claim 8, wherein said optical disc player is embodied in a computer system.

15. A computer readable medium storing a program interpreter that recognizes and causes an execution of a first function stored in a local optical disc of an optical disc player, wherein said first function causes an operations mode of said optical disc player to change to a video playback mode wherein a video menu is displayed in a foreground of a displaying device and a user agent menu is running in a background of said displaying device.

16. The computer readable medium of claim 15, wherein said first function further disables a user control interface to prevent a user from changing said operations mode of said optical disc player.

17. The computer readable medium of claim 16, wherein said first function does not disable a user control interface, allowing a user to change said operations mode of said optical disc player.

18. The computer readable medium of claim 16, wherein said program interpreter further recognizes and causes an execution of a second function that enables a user control interface to allow a user to change said operations mode of said optical disc player.

19. The computer readable medium of claim 16, wherein said optical disc player comprises a dedicated optical disc player.

20. The computer readable medium of claim 16, wherein said optical disc player is embodied in a computer system.

21. The computer readable medium of claim 16, wherein said program interpreter further recognizes and causes an execution of a second function that changes said operations mode of said optical disc player to said user agent mode wherein said user agent menu is displayed in a foreground of said displaying device.

22. An optical disc player, comprising:

an optical disc reading device to read an interactive program stored on a local optical disc;

a video/audio interface to interface with a displaying device for displaying a user agent menu and/or a video playback menu; and

a processor to execute a first function of said interactive program which changes an operations mode of the optical disc player to a video playback mode where the video playback menu is displayed in a foreground of said displaying device and said user agent menu is running in a background of said displaying device.

23. The optical disc player of claim 22, further comprising a user control interface to allow said user to change said operations mode of said optical disc player.

24. The optical disc player of claim 23, wherein execution of said first function disable said user control interface to prevent said user from changing said operations mode of said optical disc player.

25. The optical disc player of claim 23, wherein said processor is capable of executing a second function of said interactive program that enables said user control interface to allow said user to change said operations mode of said optical disc player.

26. The optical disc player of claim 22, wherein said optical disc player comprises a dedicated optical disc player.

27. The optical disc player of claim 22, wherein said optical disc player is embodied in a computer system.

28. The optical disc player of claim 22, wherein said processor to execute a second function that changes said operations mode to said user agent mode where said user agent mode is displayed in said foreground of said displaying device.
