Related data in electric video product conventionally according to the regular centralized stores of certain structure on the fixing position of NVRAM (nonvolatile memory); according to this characteristic of data storage; can be to the data message of the data that need protection record in addition, as No. ID, data name, reference position, data structure and size of data etc.In the time carrying out software upgrading, first the data message of the data that need protection in old edition software is carried out to record, form the need protection data message table of data of old edition software as shown in Table 1, then the data that these needed protection leave temporary storage area in temporarily, in BUFFER (buffer zone); Then obtain the data that need protection in new edition software, the data message of the data that need protection in new edition software is carried out to record, form the need protection data message table of data of new edition software as shown in Table 2; Again the data message of the data that need protection in the data message of the data that need protection in new edition software and old edition software is compared, relatively time, can compare item by item with data name according to data No. ID.Need protection the data message of data as example taking the new edition software shown in data message and the table two of data that needs protection of the old edition software shown in table one, there are following several situations in comparative result:
| No. ID | Data name | Reference position | Data structure | Size of data |
| 1 | ?“GAMMA” | 0x2000 | NULL | ?255 |
| 2 | ?“CHANNEL?TABLE” | 0x3000 | INT[100][3] | ?300＝100＊3 |
| 3 | ?“CHANNEL?INFO” | 0x4000 | INT[100][3] | ?300＝100＊3 |
The need protection data message table of data of table one old edition software
| No. ID | Data name | Reference position | Data structure | Size of data |
| 1 | “GAMMA” | 0x2006 | NULL | 255 |
| 2 | “CHANNEL?TABLE” | 0x3000 | INT[100][4] | 400＝100＊4 |
| 3 | “CHANNEL?INFO” | 0x4000 | INT[125][3] | 375＝125＊3 |
