DATA BYTE
DESCRIPTION
CCEN
SCCLN
enables individual Line 21 encoding; see Table 26
selects the actual line, where closed caption or extended data are encoded
line = (SCCLN + 4) for M-systems
line = (SCCLN + 1) for other systems

enables encoding in both fields
DATA BYTE
DESCRIPTION
RCV2S
start of output signal on RCV2 pin
values above 1715 (FISE = 1) or 1727 (FISE = 0) are not allowed
first active pixel at analog outputs (corresponding input pixel coinciding with RCV2) at
RCV2S = tbfH (tbfH)
end of output signal on RCV2 pin
values above 1715 (FISE = 1) or 1727 (FISE = 0) are not allowed
last active pixel at analog outputs (corresponding input pixel coinciding with RCV2) at
RCV2E = tbfH (tbfH)
RCV2E
DATA BYTE
DESCRIPTION
FAL
first active line = FAL + 4 for M-systems, = FAL + 1 for other systems, measured in lines
FAL = 0 coincides with the first field synchronization pulse
last active line = LAL + 3 for M-systems, = LAL for other system, measured in lines
LAL = 0 coincides with the first field synchronization pulse
