In the USA, the OTA ATSC 1.0 is only either 1080i at 30hz or 720P at 60hz. To
my eyes using a PC with something like a Nvidia GT 1030 GFX card I don't
see any problems with 1080i which is 1/2 my channels. I can't tell it
from 720p except using data like what you get with OSD Menu -> Playback
-> Playback Data.
On 1080i, I see FPS= 29.97+/- 0.03. On 720p, I see FPS 59.98+/-
0.05.That's using OpenGL High Quality software.
However, on the Nvidia Shield TV 2017 edition the android
mythtv-frontend shows about the same data but 1080i is +/- 0.07 jumping
to 0.12 occasionally. 720p is +/- 0.11 and steady.
I think a lot of this panning problem is due to broadcast choices. I
notice the bits per second on my major networks is about 3-4 GB per
hour, but the sub networks show reruns of the same shows at 0.8 GB per
hour. They also use 480p but the panning jitter is really bad.
