But default would be:
30FPS, 16:9 (1920x1080, 1280x720) either Progressive or interlaced.
Mostly you'll need 4:2:2</p>

1080p isn't commonly accepted, at least for paid programming or commercials in the US, and 720p is usually only accepted by ABC and Fox affiliates. But 1080i29.97 with a 4:2:2 profile is a good guess.

Yeah, as Michael already pointed out, I'd certainly expect 29.97 rather than 30 fps.  The old color pulse timing is still hanging out with us, just like the power oscillation.

<p>I recently had an opportunity to publish video for broadcast television. I need to know what the correct aspect ratio is to publish video to the broadcaster. U.S. television broadcast. I have not received additional information of what the specifications are for the videos just yet. I'm just trying to be one step ahead. Thanks.</p>

Welcome! What country? What broadcaster, if you can share that? What is the material: a program that the broadcaster commissioned, paid long form programming, or a short form interstitial like a commercial or PSA? Did they send you a spec sheet? Did you request a spec sheet if they haven't sent you one already?

Ask for the specs from your broadcaster. When HD was still a thing, the requirements were quite strict for HD, like at least 50 Mbit/s, usually 4:2:2, usually 29.97 fps interlaced or 59.94 fps progressive. Nowadays, when "HD" is being broadcast at as low as 5 Mbit/s, who cares?
