ATSC 3.0 broadcast demo at CES show

[Username1]

Well, I know a lot of you would argue that my made in china 20" Magnavox Flat CRT
NTSC box does not produce a HD image, or close, especially using the rf signal input,
but I have noticed a great improvement in picture quality since Digital came out
while watching PBS's Nature show. I know they film it using some really good quality
cameras, and since our analog days PBS was a crappy signal here. But since they stayed
on VHF it makes it up here very well now... I wouldn't mind seeing that in real HD, and
possibly one day in 4K, but I'm Not going to sit within 6 feet of the screen..... Well
probably not all the time....

If it's HDMI, how am I supposed to record shows?

They dont want people to record shows anymore.

Pretty soon they turn on the digital copyright protection on like the DVDs and macrovision on the old VHS tapes.

I agree.With the new DTV realignment coming up .The OTA channels will be less there is now.The vacated channels probably will be auctioned of to the wireless idiots.Alot of pocketed money going around.

Reminds me of one such show where a scientist was explaining his theory of why zebras are striped. He was watching film of a herd of zebras, and saw the stage coach wagon wheel effect (wheels spinning in the wrong direction) as the zebras were running. And he thought this would be what a lion would see in live action in the field (zebras seemingly running in the opposite direction). I in person later looked at cars driving past, to see if maybe my eye would see this wagon wheel effect (I assume lion eyes and mine are enough similar), and as I expected, I didn't see the effect. As my (and lion eyes) don't use shutters running at 24 frames a second, and thus I and lions won't get this alias product. Unless they watch movies of running zebras.

I've seen the wagon wheel effect on cars on the highway in person....

I'm guessing that there must have been some *strobing* effect going on with the light source such as 60 Hz blinking of street lamps or sunlight streaming through a forest, or perhaps strobing related to viewing conditions, such as observation of the vehicle through a picket fence.

I've observed it in direct view with normal sunlight and no strobing.
