6.7.6.5
BT.656 Mode
BT.656 is the basic standard that specifies the encoding of
the control lines into the data bus. In this mode the sepa-
rate control lines are encoded into the data bus as speci-
fied by Recommendation ITU-R BT.656.
Each line begins with a Start of Active Video (SAV) header,
and ends with an End of Active Video (EAV) header. Each
of these are four-byte sequences beginning with FF, 00,
00. The fourth byte of the header provides important infor-
mation about this line. The bit format of the SAV and EAV
headers is shown in Table 6-62.
The T bit is specified in BT.656 as a constant logic 1. The F
bit indicates Field - 1 for even (also called Field 2), 0 for
odd (Field 1). The V bit indicates Vertical Blanking. The H
bit indicates Horizontal Blanking. Bits P3 through P0 are
protection bits used to detect and correct single-bit errors.
The bits are defined as follows:
P3 = (V + H) + ~T
P2 = (F + H) + ~T
P1 = (F + V) + ~T
P0 = (F + V) + H
