Our test pattern includes a feature to reveal field dominance reversal.  Here's the demo:

HI, Dennis, 

My comment wasn't meant to be a slight. My apologies.  Looking again at what I wrote, that seems possible given that I said. "nobody does anything about..."  Can I amend that to "something ought to be done about?"

I'm sorry that stuff with the wrong field order gets as far as the edit room... and I do understand the nature of needing to be able to see fields in order to detect the problem. 

That said, its distressing—jarring is my usually reaction—to see this pop up in network flagship broadcasts, especially where the piece the problem clip is in wasn't time-critical.

I appreciate that you'd fix it if there was time to do so, and know that it's not always possible, especially with breaking news coming in from the plethora of possible sources we have today.

I sometimes have to wonder if this is a reflection of progress.  I was trying to come up with the interlaced equivalent of "Two steps forward and one back" which is what's taking place on a field level, but it's not computing this late in the day.

Have you discovered any patterns in terms of what circumstances lead to the problem, and what could be done at the origin or in-path to address the issue before it hits the editing room?

Ted

The problem of importing computer-originated video material with wrong field order is partly due to the fact that you cannot see the field order on a computer monitor.  Field order is only seen on a TV or broadcast monitor; one that can show TV fields.  Computer monitors are all progressive displays.  As a result, the operator doing the importing cannot see the error, unless of course he or she has a broadcast monitor connected as well.
