DATA BYTE
DESCRIPTION
TTXHS
start of signal on pin TTXRQ (standard for 50 Hz field rate = tbf)
values above 1715 (FISE = 1) or 1727 (FISE = 0) are not allowed
end of signal on pin TTXRQ (standard for 50 Hz field rate = TTXHS + 1402)
values above 1715 (FISE = 1) or 1727 (FISE = 0) are not allowed
TTXHE
DATA BYTE
DESCRIPTION
TTXOVS
TTXOVE
first line of occurrence of signal on pin TTXRQ in odd field = TTXOVS + 1 (50 Hz field rate)
last line of occurrence of signal on pin TTXRQ in odd field = TTXOVE (50 Hz field rate)
DATA BYTE
DESCRIPTION
TTXEVS
TTXEVE
first line of occurrence of signal on pin TTXRQ in even field = TTXEVS + 1 (50 Hz field rate)
last line of occurrence of signal on pin TTXRQ in even field = TTXEVE (50 Hz field rate)
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
LAL
DATA BYTE
DESCRIPTION
LINE
individual lines in both fields (PAL counting) can be disabled for insertion of teletext by the respective
bits, disabled line = LINExx (50 Hz field rate)
this bit mask is effective only, if the lines are enabled by TTXOVS/TTXOVE and TTXEVS/TTXEVE
