Shown below is an example in which received 525i5994 SDI video is being up-converted to 720p5994. The settings shown in the
example below provide for directing the scaler to re-aspect the 4:3 input video to full, centered 16:9 re-aspecting, and mark the
output video with the AFD code representing the new re-aspected H/V format.
525i Video Input
w/ AFD = 0010
(4:3 -> 16:9)
Noting that the incoming video contains AFD coding, Trigger on
A
AFD is set to AFD, with other choices set to Off. The settings here
allow ARC to trigger only on an AFD-coded input.
In this example, it is desired to use the H/V re-aspecting inherent in the received
B
video ARC, perform the re-aspecting with no modification, and output an AFD code
representing the re-aspecting performed.
As such, Force Input Mapping is set to Follow Trigger, thereby bypassing the
Output ARC Cross-Matrix Map table and directly perform the re-aspecting defined by the
received code (in this example, Letterbox 16x9). Also in this example, the scaler is directed
to apply the output AFD re-aspecting by setting Scaler Follow AFD to Enabled.
In this example, since only AFD is to be outputted, AFD Output
C
is set to Enabled, with WSS and VI choices set to Disabled.
AFD Status shows AFD code now being outputted.
The insertion line number (using its default value here), can be
set using the AFD Output Line controls (for the progressive
format in this example, the Field 1 control serves as the line
number control).
