Table 1. VID_IO_OUT Interface Port Descriptions
Signal I/O Description
VID_IO_OUT_data[n-1:0] O

Native video output data

Where n=bpc*ppc*3.

For 10bpc at 2ppc, n=10*2*3=60

For 12bpc at 2ppc, n=12*2*3=72
VID_IO_OUT_active_video O Native Video active video output
VID_IO_OUT_field O

Native video field output

For interlaced videos, fid toggles based on the field

selected:

0- even field

1- odd field

For progressive videos, fid is set to 0.

Note: The fid is expected to toggle in psf and 3G-level B progressive videos, as in these modes, one progressive frame is split into two fields. These two fields are transported independently, similar to interlaced video, and again combined and correctly paired together at the receiver side with the help of the fid signal to construct the original progressive frame.

For example, when 1080p 60 Hz video is transported on 3G-SDI level B-DL, the video transport is actually 1080i 60 Hz. The transport is interlaced, but the picture is progressive.
VID_IO_OUT_hblank O Native Video hblank output
VID_IO_OUT_vblank O Native Video vblank output
