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

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Referring to Fig. 1, the embodiment of the invention discloses a kind of flow chart of method of programs of set-top box list recovery, comprise step:
After S11, Set Top Box power on, from memory block, obtain program data;
S12, to the actual programs data summation in described program data, obtain actual programs data and;
It should be noted is that, program data comprises two parts, is respectively header check information and actual programs data, header check data comprise version number and verification and etc.
Verification and referring in data processing and data communication field, for the one group of data item in verification destination and.These data item can make numeral or in the process of counter control, be counted as other character strings of numeral.
S13, judge described actual programs data and whether be not equal to described program data verification and, if so, perform step S14; Otherwise, execution step S15;
S14, load the program data of backup area, and cover the described program data of described memory block;
S15, end recover flow process.
In summary it can be seen, the present invention is by by actual programs data in Set Top Box with the verification of program data with compare, whether realization has damage or the judgement of losing to the program data of memory block, when the program data of memory block damages or loses, from backup area, load program data, and cover the program data of memory block.So, the present invention can effectively prevent from, because program data damages the problem that causes original program data to be lost, thereby realize, all program datas in memory block being recovered, and reaches an object to the rendition list protection.
It should be noted is that, the backup area in the present embodiment can be the database in Set Top Box, can be also the External memory equipment of Set Top Box.
When External memory equipment that backup area is Set Top Box, between Set Top Box and External memory equipment, by serial ports instrument, realize data backup.

S16, in the situation that the version number of the described program data of described memory block higher than the version number of the described program data of described backup area, load the described program data of described memory block, and cover the described program data of described backup area.
Can find out, by version high program data in memory block is covered to the program data that backup area version is low, can guarantee the consistency of the program data of backup area storage and the program data of storage area stores, thereby when the program data of storage area stores damages, the program data recovering from backup area and the data of loss are just the same.
It should be noted is that, the version number of the rendition list of memory block is positioned at the header check information of the rendition list of this memory block, and same, the version number of the rendition list of backup area is positioned at the header check information of the rendition list of this backup area.
Referring to Fig. 4, the flow chart of the method that the disclosed another kind of programs of set-top box list of the embodiment of the present invention recovers, from embodiment illustrated in fig. 1 different, after execution of step S14, can also comprise:
S41, when described Set Top Box is play the program of the satellite frequency that comprises program data, obtain the program data of described satellite frequency transmission;
S42, from described program data, obtain the version number of described program data, described version number is arranged in the header information of described program data;
S43, when described version number is during higher than the version number of the described program data of described memory block, download described program data;
S44, described program data is saved in to described memory block, is saved in described backup area simultaneously;
S15, end recover flow process.
Certainly, when the program data of memory block does not damage, Set Top Box also can be upgraded the program data of memory block automatically.
In summary it can be seen, the present invention can download up-to-date program data automatically, and the program data of memory block is upgraded, also the program data of backup area is upgraded simultaneously, take and guarantee that the program data of backup area is up-to-date program data.
Be understandable that, by External memory equipment, also can upgrade the program data of memory block, now, between Set Top Box and External memory equipment, be connected with serial ports instrument.
Referring to Fig. 5, the disclosed a kind of flow chart to program data renewal process in Set Top Box of the embodiment of the present invention, renewal process is applied to serial ports instrument, comprises step:
The selection instruction of the program data that the need of S51, reception user input upgrade;
S52, the described selection instruction of foundation are obtained the program data corresponding with described selection instruction from External memory equipment;
Described in S53, verification, program data data integrity whether, if so, performs step S54, otherwise, execution step S55;
S54, described program data is updated to the memory block of Set Top Box;
S55, renewal finish.
Embodiment is corresponding with said method, the invention also discloses the system that a kind of programs of set-top box list recovers.
