Vertical Interval Strobe Selection
Performer generates its own Vertical Interval strobe, which times the
switching of video so that switching occurs within a region of each video
field when there is no active video. Performer-HD generates this from look-
ing at the parallel video data, extracting vertical interval timing informa-
tion and sending out a pulse at a specific time during vertical interval. The
DIP switch S4 is used to tell the Performer-HD which line to switch on. The
choices are lines 1, 5, 6, 7, 8, and 9; corresponding to lines 563, 567, 568, 569,
570, and 571 in the second field.
