Line Number Represents Count
In
Generic
mode, the line number represents the number of a count
instead of a real line number.
Line:Field 1
and
Line:Field 2
are used to
indicate where the counting starts. For an interlaced video signal, the
counting starts from the rising edge of the first vertical serration pulse of
Field 1 and/or Field 2.
