Exactly, and each time they trust in new algorithm we lost more. The algorithms to "solve" compression issues just try to hide the defects, like MPEG-4 did over MPEG-2, but created other PROBLEMS, like worse shadow details when in low bitrate, and much more fall of quality during significative motion, since in motion there are few things in common to the algorithm compress.
The digital sat rent chanels system here have almost 20's years, and when was released had better image than today, since was only 10 channels. I didn't got the early beggning, but got when was about 30 or so channels, and had very few artefacts. It was SD,
and today, in HD it's much worse than 18 years ago..
But even so a prime analogic signal was bettert in texture sharpness than the sat digital in early days, cause there was chanels present in both, open broadcast analogic and in the digital sat system, and I could change in less than a second from one to other source, and the analogic despite very few noise, was better. When they added more and more chanels the analogic became far better than the digital. When HD arrived, it was so compressed that had very few difference to the digital non HD.]
Save a image in a JPEG format in lowest quality allowed and you will understand me. It reach of point of "
crapness" where resolution don't matter, given the absurd compression.
The more elaborated the compression, more processing power it takes. And real time encoding will be always worse, since it's made in hurry, cause a well encoded analyze would take more time and would require much more processing power to be able to render in real time.
That's why I keep my position; "HD DIGITAL VIDEO AND DIGITAL TVs are just a lie, having no real resolution or ability to display the resolution reported.
JUST A F...KING LIE !!! It's like need to buy 4 pounds of meat to get just 1 pound of meat, since the other 3/4 it's just cartilage/fat/bones.
If things keep this way digital will never be good, cause they will just add more chanels and keep the crap standart of garbage.
I see reports about people notice digital artefacts in the credits of movies on digital theaters. I don't even go to movies, cause I know I will be revolted, cause on Brazil they always will get a sh...t system for low price.
PEOPLE ARE STUPID. They spot noise and ghosting of analogic signal and complain, but if they see a digital image with no noise or ghosting, even than with smoot soft details instead of sharp textures, they don't complain.
They also don't complain about white clipping or banding.

ATSC 3 which is being released late this year claims to solve most of the compression issues but more likely they will just cram more channels into less bandwidth bringing us back to current state.
I use a 27” trinitron to watch classic content and play my snes
The HD set I use for YouTube and the like.
Each display type is a tool for a purpose .
