A lot of questionable "facts" bandied about in this one.
I don't think there are 15 stops above SDR in HDR, as Ron stated several times. HDR (ST2084) has 100x the peak signal as SDR, more like 7 stops. (Still a lot).
The discussion about outdoor sun and shade on a football field is pretty silly too. The answer to this is compression in the camera, not HDR, although that is debatable.
If you go to one of those games, you find yourself shielding your eyes from the bright part of the field, in order to see the darker part. So now you want to bring that hard to see action into your home by putting a realisticly bright field on the screen, while trying to see action in the darker portion? It does not any sense. Instead, you do what "WDR" surveillance cameras have been doing for the past 5 years, compress the gray scale to accommodate the wide dynamic range, but still display on SDR.
Finally, regarding new broadcast digital standards. I suspect the broadcast industry will be dead before this comes to pass. Scott alluded to this by wondering if broadcast is relevant anymore. Well most people don't get the networks over the air, but instead via cable or satellite. And those that do, tend not to be the demographic that advertisers want.
With the growth of smart phones, and many people turning to internet streaming, the whole "value to the citizen" that has warranted free use of the air waves for the broadcasters comes into question.
Personally, I think the congress should pass legislation that would put a significant license fee for the use the TV spectrum. And increase that fee over time, with the goal of eliminating over the air TV. The spectrum has better uses. I could see the local TV stations remaining the same, just not broadcasting over-the-air.
What about those who can't afford cable or satellite? I could see the networks leasing space on dish or direct TV or similar, and making the signals free.
Anyway, good show, and keep them coming. Too bad Joe Kane could not make it. He is always worth a listen.
Edit: Final thought. He shouldn't be using 100% level bars for st2084. He should use 50% levels, as they are closer to what 100% is on SDR.
Since no display can achieve 100%, all displays are going to clip at 100%.
