  1. The fid is expected to toggle in psf and 3G-level B progressive videos. In these modes, one progressive frame is split into two fields which are transported independently (similar to interlaced video) and then 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 a 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.
