input frames per second might be too low for the video processor.
input frames per second might be too high for the video processor.
to say it is the televisions fault.. the answer is 50/50 when doing the tests at home.
you could hook it up to the computer and run 60 frames per second..
but
if the video processor inside the television is messing around with the video frames.. you will continue to see that same 60 frames per second.. even if the frames per second from the television are actually 120 or 30.
i have seen free high definition over the air with an antenna.. my focus wasnt lost with high movement.
this was viewed on a crt monitor.
i mean.. i didnt have my nose up to the screen to try and detect something that wouldnt be seen from 2ft away.
you really need a different input to see if the problem is because of your input choice?
sure..
maybe the component input does it, but the hdmi doesnt do it.
but as i said..
digital television from an antenna didnt blur on my crt.
i am about 50 miles away from the broadcast tower.. and if you dont try a different video input, that would be quite a guess.
why cant you connect the television up to the computer?
is it a laptop with no video component or hdmi outputs?
i mean.. you already have an antenna up.
did you have television connected to the antenna when the switch to digital happened?
maybe it is your signal being received?
if there was a repeater that blurred the video when there was motion, i could see that happening.
if your distance from the broadcast tower is really far, i could imagine some blurring of the motion because of signal loss (like losing transients in the air because the signal isnt strong enough to transfer the tiny pulses)
maybe it is the amplifier on your antenna?
the digital packets dont always have to be exact.
yes, if the signal was not able to be received 'solid' enough.. then you would get the square pixelation.
but
depending on modulation technique.. solid video could come across stronger than moving video.
to say that the antenna itself is using key frames.. or the air is absorbing and thus accumulating key frames.. then it could be possible.
there are options that might have been chosen.. and without those options being ruled out, it is a whirl wind of guesses.
