Shown below is an example in which received 625i50 SDI video is being up-converted to 720p50. 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.
625i50 Video Input
w/ WSS ETSI = 5
(4:3 -> 16:9)
Note: Active ARC control available only with card equipped with
scaler. On non-scaler card, ARC control/convert function
only manipulates output SDI ARC codes and has no local
effect on card output aspect ratio.
Noting that the incoming video contains WSS coding, Trigger on
A
WSS is set to ETSI, with other choices set to Off. The settings
here allow ARC to trigger only on an ETSI-coded WSS received
code.
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).
