Description

VID_IO_IN_data[n-1:0]

I

Native video input 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_IN_active_video

I

Native video active video input

VID_IO_IN_field

I

Native video field input
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: fid is expected to toggle in case of 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 receiver side with the help of 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_IN_hblank

I

Native video hblank input

VID_IO_IN_vblank

I

Native video vblank input
