Problems solved by technology

[0003] However, when operations such as editing, searching, and setting are performed on the data in the storage area, if unexpected situations such as power failure occur, the program list data in the storage area will be confused and damaged, and the integrity of the program list data will be damaged. Even some program information previously searched, edited, and set by the user no longer exists, which brings great inconvenience to the user when watching TV.
Although some set-top boxes have a protection function and can restore part of the program list, the restored program list is the operator's default, and the program information set by the user cannot be restored.

Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0044] see figure 1 , the embodiment of the present invention discloses a flow chart of a method for recovering a set-top box program list, including steps:

[0045] S11. After the set-top box is powered on, acquire program list data from the storage area;

[0046] S12. Summing the actual program data in the program list data to obtain the sum of the actual program data;

[0047] It should be noted that the program list data includes two parts, namely the header ...

Abstract

The invention provides a recovery method and system for a STB program list. Whether program list data of a storage region are damaged or lost is determined by comparison of the actual program data sum in the STB and program list data verification sum, and when the program list data of the storage region are damaged or lost, program list data are loaded from a backup regions and cover the program list data of the storage region. Accordingly, the loss of the original program list data caused by damage to the program list data can be effectively prevented, all program list data in the storage region are recovered, and the program list is protected.

Description

technical field [0001] The invention relates to the technical field of set-top boxes, and more specifically, relates to a method and system for recovering a program list of a set-top box. Background technique [0002] A set-top box is a device that connects a TV set to an external signal source. It can convert compressed digital signals into TV content and display it on the TV set. The set-top box has a program list storage function, which allows the user to normally watch the previously stored programs after turning on the box next time. [0003] However, when operations such as editing, searching, and setting are performed on the data in the storage area, if unexpected situations such as power failure occur, the program list data in the storage area will be confused and damaged, and the integrity of the program list data will be damaged. Destruction, even some program information previously searched, edited and set by the user no longer exists, which brings great inconven...
