Digital video encoder
vertical sync shift between RCV1 and RCV2 (switched to
output); in master mode it is possible to shift Hsync (RCV2;
CBLF = 0) against Vsync (RCV1; SRCV1 = 00)
first line of occurrence of signal on pin TTXRQ in odd field
last line of occurrence of signal on pin TTXRQ in odd field
first line of occurrence of signal on pin TTXRQ in even field
last line of occurrence of signal on pin TTXRQ in even field
first active line: measured in lines; FAL = 0 coincides with the first field synchronization pulse
last active line: measured in lines; LAL = 0 coincides with the first field synchronization pulse
