sliced data identification: NEP
identifier
double word count: NEP
It should be noted that the number of valid bytes inside the stream can be seen in the BC byte.
internal data identification 1: OP
internal data identification 2: OP
double word number n, byte number m
last double word byte 4; remark: for SAV/EAV framing DC is fixed to 0Bh, missing data bytes are filled up; the fill value is A0h
the check sum byte, the check sum is accumulated from the SAV (respectively DID) byte to the D
number of valid sliced bytes counted from the IDI1 byte
end of active data; see
end of raw VBI line

For SAV/EAV mode DC is fixed to 11 double words (byte value 4Bh)
For ANC mode it is: DC =
