Lines 625
Select the lines into which data is inserted in the SD
output stream when down converting. Q-Down-ATG
3G can deal with both ancillary data timecode (ATC)
and vertical interval timecode (DVITC). When
outputting Standard Definition, Q-Down-ATG 3G will
also convert the ATC to vertical interval timecode
(VITC) which is always repeated on two adjacent
video lines, one in each field. When using Q-Down-
ATG 3G to convert 1080p to 1080i output, the ATC
and AFD are inserted in lines 9+571 and 11+547
respectively.
Lines 525
As 625 above but with the addition of Closed
Caption insertion. When down converting 59.94Hz
video, Q-Down-ATG 3G takes the HD closed
captions (to the CEA-708 standard) and extracts the
data it needs to insert the corresponding SD closed
captions (to CEA-608) into the SD output stream.
