Abstract

A digital consumer product having a menu system includes an audit trail system having an audit trail management system that removes screens from an audit trail triggered by the addition of a new screen to the audit trail. Menu screens and/or video screens are added to the audit trail as navigated by the user and, accordingly, certain screens are removed from the audit trail. The audit trail management system also provides the ability to store two or more instances of full-screen video and all intervening screens, the ability to provide all data and temporary state information for all screens stored in the audit trail and the ability to restore and refresh them, the ability to retain partial screens and screen objects and the ability to restore and refresh them, and the ability to remove any or all stored screens.

2. The method of claim 1, wherein the step of adding the next screen if the predetermined number of video screens has been saved in the audit trail, further comprises the step of removing any screens added before the one of the predetermined number of video screens.

3. The method of claim 1, wherein the step of adding the next screen if the predetermined number of video screens has been saved in the audit trail, further comprises the step of removing any screens between the one of the predetermined number of video screens and any immediately following video screen before adding the next screen to the audit frail.

4. The method of claim 3, wherein the one of the predetermined number of video screens is a first video screen in the audit trail.

5. The method of claim 4, further comprising the step of if the next screen is not a video screen and an instance of the next screen is in the audit trail between one of the predetermined number of video screens and a next one of the predetermined number of video screens, removing all screens added before the next one of the predetermined number of video screens.

6. The method of claim 4, wherein the first video screen is a first screen in the audit trail.

7. The method of claim 4, further comprising the step of if the next screen is not a video screen and no instance of the next screen is in the audit trail, adding the next screen to the audit trail.

8. The method of claim 4, wherein the predetermined number of video screens comprises two.

9. The method of claim 4, further comprising the step of:

retaining screen data and temporary state information for an added next screen, the retained screen data and temporary state information restored along with a restored added next screen during backward traversing of the audit trail.

10. The method of claim 9, further comprising the step of:

updating, in the memory, retained screen data and temporary state information for an added next screen during restoration of the added next screen during backward traversing of the audit trail.

11. The method of claim 9, further comprising the step of:

removing a screen from the stored audit trail including notifying any retained screen data and temporary state information for the removed screen that they will be deleted in order to restore any system states that have been changed.

12. The method of claim 4, further comprising the step of:

retaining a partial screen associated with an added next screen, the retained partial screen restored with the added next screen during backward traversing of the audit trail.

13. A digital television apparatus providing menu screens and video screens, the digital television apparatus comprising:

a storage device for storing an audit trail comprising one or more menu screens and video screens; and

a controller coupled to the storage device and operative to add a next screen comprising one of a video screen and a menu screen to the audit trail, wherein;

(a) if the next screen is a video screen and a predetermined number of video screens has already been saved in the audit, the controller removes one of the predetermined number of video screens from the audit trail before adding the next screen to the audit trail, and (b) if the next screen is not a video screen and an existing instance of the next screen is has already been saved in the audit trail, the controller removes the existing instance of the next screen and all screens thereafter from the audit trail before adding the next screen to the audit trail.

14. The apparatus of claim 13, wherein if the predetermined number of video screens has been saved in the audit trail, the controller further removes any screens added before the one of the predetermined number of video screens.

15. The apparatus of claim 13, wherein if the predetermined number of video screens has been saved in the audit trail, the controller (30) further removes any screens between the one of the predetermined number of video screens and any immediately following video screen before adding the next screen.

16. The apparatus of claim 15, wherein the one of the predetermined number of video screens is a first video screen in the audit trail.

17. The apparatus of claim 16, wherein if the next screen is not a video screen and an instance of the next screen is in the audit trail between one of the predetermined number of video screens and a next one of the predetermined number of video screens, the controller removes all screens added before the next one of the predetermined number of video screens.

18. The apparatus of claim 16, wherein the first video screen is a first screen in the audit frail.

19. The apparatus of claim 16, wherein if the next screen is not a video screen and no instance of the next screen is in the audit trail, the controller adds the next screen to the audit trail.

20. The apparatus of claim 16, wherein the predetermined number of video screens comprises two.

21. The apparatus according to claim 16, wherein the controller is further configured to:
