(contents value 01,03 and 14 that byte index value is [0] to [2]) is respectively with the data D1 of a correct data table to data D10's
(contents value that byte index value is [0] to [2]) is compared in multiple known headers, and finds out in the Header portion with DX extremely
The identical at least one correct header of contents value of a few byte.In the example of Fig. 5, the header of data D1 to data D10
Byte index value is 01 and 03 (as thick line wire institute frame shows) for the contents value of [0] and [1], with the Header portion of data DX
Byte index value is that [0] and the contents value 01 of [1] are identical as 03.The byte index value of the header of data D1 to data D10 is [0]
Into three bytes of [2] contents value, as long as there is the byte of the contents value of byte Header portion corresponding with data DX's
Contents value it is identical, correct header can be chosen as.In this example, obtained at least one correct header be, for example, data D1 extremely
The header of data D10.These headers correspond to multiple first given datas, are also data D1 to data D10.Wherein, above-mentioned
Correct data table be, for example, to have recorded the correct data D1 to D10 of nearest 10 Successful transmissions.

Contents value), and find out the identical at least correct data group of the contents value of at least one byte in the data portion with DX.In
In the example of Fig. 6, the byte index value of data D2 is the contents value 0A of [6] and the byte index value of the data portion of data DX is
[6] contents value 0A is identical, and the byte index value of data D5 is the byte of the data portion of the contents value FF and data DX of [4]
Index value is that the contents value FF of [4] is identical, as thick line wire institute frame shows.Therefore the data group quilt of the data group of data D2 and data D5
It is selected as correct data group.In this example, an obtained at least correct data group is, for example, the data group of data D2 Yu data D5.
These data groups correspond to multiple second given datas, are also data D2 and data D5.
As shown in the step 324 of Fig. 3 B, cyclic redundancy check Comparison Method is by Solar Data SD's (or crossing filter data FD)

(contents value that byte index value is [7] to [8]) is compared according to multiple known cyclic redundancy check code of D1 to data D10,
And it is superfluous to find out the identical at least correct cycles of the contents value of at least one byte in cyclic redundancy check code part with DX
Remaining check code.In the example of Fig. 7, the byte index value of data D5 is the cyclic redundancy school of the contents value CB and data DX of [7]
It is identical for the contents value CB of [7] to test the byte index value of code part, if thick line wire institute frame shows, therefore the cyclic redundancy school of data D5
It tests code and is chosen as correct cycles redundancy check code.In this example, an obtained at least correct cycles redundancy check code is, for example,
The cyclic redundancy check code of data D5.At least a correct cycles redundancy check code corresponds at least one third given data for this,
It also is data D5.
The processing unit 204 of data modification device 104 or data modification device 104 is according to this at least one first datum
