Merci, Olivier. That's what I suspected. For some reason, TF1 did not
explain the second choice you listed.
Another thing is that there appear to be, for now, two program streams over
one multiplex, in Paris, Lyon, et Marseille. In Paris, UHF Ch 23. Which must
mean that they had to go to 64-QAM, vs 16-QAM they use for SDTV. Which is
most likely why you're reading about reception issues at longer distances.
Low power, 64-QAM, no SFN. Makes it difficult. Even with H.264, 1920 X 1080
at 50i must require a good 10+ Mb/s.

For all the moaning about Table A3 of A/53, according to that TF1 site,
neither 24p nor 30p of any sort are considered in the TNT HDTV choices. Only
50/60i and 50/60p. I suspect that will change.
