Also bear in mind that outside of NTSC-land, the SD broadcast will often be PAL 16:9 FHA, not letterbox. (And 14:9 protect is a common spec for PAL.)

Any time I've made FHA Beta or DigiBeta it's for overseas, where I am sure the rate of HD adoption is far less than the meager amount it is here. That said, they take the FHA tape and do a few things with it. First, they treat it like it's an HD master and stretch to fill broadcast for HD. Then, for SD downconvert, they don't take the tape as is and reformat, they take the upconverted HD stream and downconvert from that, and that will be either letterbox or center-cut. Since you have zero control over what's happening there, for all these deliveries I ignore the stuff that says 14:9 safe and go straight to my 4:3 inside 16:9 overlay. Obviously for the bug stuff it only matters for the US native (Discovery) broadcast, which just says no text behind where the bug goes. So if you play by the most conservative rules, they can't kick you out of the sandbox.That said, if your delivery isn't (ever) intended for overseas distribution, I would bark back at them to explain why the complaint when they know the transmission modes. But most likely somehow some way they are hedging their bets and making sure all accepted content is good for the whole world.

Subject: Today's Episode of QC Corner what does 14;9 protect really mean?
So the delivery spec for a show I'm doing for discovery has a safe title grid with bug safe areas that basically maps out traditional safe title for 16x9 smpte safe action and safe title along with a 14:9 Protect. The instructions read use this template for all projects created in 1080 line High Definition and airing in SD 16x9 Letterbox. So I opt for the more conservative 14:9 safe to avoid hassles down the line. Now there is another distribution channel foreign whose delivery requirements include digibeta Pal and NTSC FHA 16x9 (14x9 protected-super & graphics 4x3 safe) Because all the graphics have no text and all my titles are 14:9 protected I figure I'm good to go for the added distribution channel.
Well enter QC monkeyville where they tell us the titles are out of 4x3 and will be cut off. Basically I've found 14:9 protect is virtually 4x3 safe action when setting the Avid grid to 4x3 inside 16x9 so I'm confused as to why it would be cut off on an FHA 16x9 dub. I tell them that I realize it's more like 4x3 safe action but that's the specs for the show. Meanwhile they keep squawking about 4x3 safe title so we end up driving over to have a discussion about what part of FHA dub don't they get. The tune changed from things will be cut off to it might be a pixel out of safe action. I'm curious how others are approaching these situations. I figure if they ask for a FHA digibeta it's very unlikely that the show will air center cut but more likely letterbox. At least that's what the discovery channel bug clearance etc... suggests. Given the show is being delivered on HDCam masters my understanding is most broadcasting distribution these days is only done in HD and it's the cable and satellite head ends that use a dual receiver to do a downconvert on the fly for the SD tier needs. Given this isn't it unlikely the digibeta would be used for transmission? I guess given the newer tolerances like IIRC PBS saying safe action and title are 3 and 5 percent in not 10 and 20 like the old days should I really be making everything 4x3 safe? Especially when the specs read as they do? When I mentioned that PBS's newer tolerance the QC person well traditional is still 20 and 10 percent so we decided to leave the titles as is for now and let the broadcaster complain. Just a fine day to play in the QC sandbox.
