NEP = inverted EP (see note 2).
EP = Even Parity of bits 5 to 0.
FID = 0: field 1; FID = 1: field 2.
I1 = 0 and I0 = 0: before line 1; I1 = 0 and I0 = 1: lines 1 to 23; I1 = 1 and I0 = 0: after line 23; I1 = 1 and I0 = 1:
line 24 to end of field.
Subaddress 5DH at 3EH and 3FH are used for ITU 656 like SAV/EAV header generation; recommended value.
V = 0: active video; V = 1: blanking.
H = 0: start of line; H = 1: end of line.
DC = Data Count in Dwords according to the data type.
OP = Odd Parity of bits 6 to 0.
10. LN = Line Number.
11. DT = Data Type according to table.
