In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Related data in the electric video product usually according to certain structure clocklike centralized stores on the fixing position of NVRAM (nonvolatile memory); this characteristic according to data storage; can be to the data message of the data that need protection record in addition, as ID number, data name, reference position, data structure and size of data etc.When carrying out software upgrading, at first the data message to the data that need protection in the old edition software carries out record, form the need protection data message table of data of as shown in Table 1 old edition software, the data that then these needed protection leave the temporary storage area in temporarily, in BUFFER (buffer zone); Obtain the data that need protection in the new edition software then, the data message of the data that need protection in the new edition software is carried out record, form the need protection data message table of data of as shown in Table 2 new edition software; Data message with the data that need protection in the data message of the data that need protection in the new edition software and the old edition software compares again, can compare item by item according to ID number of data and data name in the time of relatively.With the need protection data message of data of the data message of data and the new edition software shown in the table two that needs protection of the old edition software shown in the table one is example, and there are following several situations in comparative result:
| ID number | 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
