green when VITC type timecode is detected and the Timecode 2 Presence icon turns green when LTC type timecode
is detected.

5.4.5 3G/HD Output – AFD tab
The Active Format Descriptor (AFD) flag is used to identify the aspect ratio and protected areas of a video signal. The
XVP-3901-DPI uses this flag in some cases to adjust the output aspect ratio and image cropping to obtain the best
possible presentation of the image. Since the XVP-3901-DPI
3G/HD Output will be active only with 3G/HD Input, the AFD
flag (SMPTE 2016) is sent in an ancillary packet, normally
found on line 11 in the vertical ancillary space. When an AFD
flag is present at the input, the card will not perform an
automatic adjustment of the aspect ratio, but the AFD
generated will be according to the table in the appendix 2.
