5.5.4.3 Meta / Namedropper sub-tab
Namedropper is a method of inserting control information for
down-stream graphics inserters. It is a waveform-shape
located on line 18 in SD.
The XVP-3901 detects the presence of Namedropper data in
the program arriving at its input, and flags it using the status
icon in this panel, which turns green when Namedropper
data is detected.
5.5.4.4 Meta / Timecode sub-tab
Presence
: A presence icon is available for each type of
incoming ATC packet. The Timecode 1 Presence icon turns
green when VITC timecode is detected and the Timecode 2
Presence icon turns green when LTC timecode is detected. If
the input is SD, then the presence of each icon depends on
the selection of the SD Detection Line parameter.
SD Detection Line
: This parameter is only available when the
input signal is SD SDI, and is used only for timecode
presence. Select
AUTO
mode to automatically detect the line
that contains the timecode. If time code appears on multiple
lines, the first is selected. Select a specific line if desired; this
allows a choice to be made when multiple time code lines are
present.
