ATSC 3.0 - Blu-ray Forum

As I said again, a lot of technobabble that makes sense to some people.May I have a quick description of what the 3D NRT standards is?

If it's what I said that it was an alternate frame standard that locks out the "auxiliary eye" and presents it in 2D, that's EXACTLY what I've been advocating, a way to add 3D into a broadcast wihtout stepping on the toes of 2D watchers. The way 5.1, and closed captions, and foreign languages are now.

Even if the format were to be alternate frames, there was no way to lock out the other eye on non 3D TVs until ATSC 3.0 has been proposed. Side-bv-side / top-and-bottom, alternate rows, alternate columns, or checkerboarding would have all been awful to convert from 3D to 2D.

Probably the easiest standard is to cut the frame rate in half, (especially when retro TV stations on digitial OTA have a Hz rating of 30 natively, and add a new meta tag of "x 2 eye" so a standard TV that ignores the "x 2 eye" metatag of a 30 Hz x 2 eye broadcast would read it as a 30 Hz (with an implied x 1 eye),and that is probably the easiest thing to do to make a 2D-compatible 3D.

And it's passive so, just like a B/W TV just ignores the color signal, only the "main eye" will be seen by an older TV and just ignores the "helper eye" data as junk. Sort of like undecoded closed captions, or undecoded Dolby 5.1.
