All it takes is a dedicated satellite dish. A $2000 tuner, not mentioned in this article, and an 8k TV, which starts at over $4000 for a 65 in.
That's better than I'd have assumed.
Fun fact, the recommended viewing distance for an 8k 65in display is 2 feet. That would make for a pretty cozy viewing experience. Your family of 4 crammed shoulder to shoulder trying to all sit 2 ft away from a 65in display.
...if you're going for the IMax experience, where it fills your field of vision. But, stuff has to be mastered for that, because most details near the edges will be missed. So, it's not like you could just watch existing movies like that.
Anyway, I'm thinking 65" is mainly for viewers. For a family, you'd need to go wall-sized.
As the article mentions, 8k broadcasts aren't leaving Japan any time soon.
The Japanese have always been way out ahead, on this sort of thing. They had analog HD broadcasts, as far back as the late 80's or early 90's. They were first to embrace widescreen, as well.
Just in case this whole thing didn't seem absurd enough, the 8k broadcast has 22.2 surround sound.
That's only a little more extreme than the Theater version of Dolby Atmos.
Looks totally practical for a home setup. I'm going to start working on this for my living room so I am ready when it comes to the US.
The thing to remember is that just because a sound is mixed so that it originates from a certain position doesn't mean that you need to have a real speaker there. I'm sure most setups will use far fewer speakers and fill in the rest with virtual surround techniques.
The other approach is just to give each sound a set of 3D coordinates, which is a lot more flexible in terms of how you reproduce it. However, it places more processing burden on the receiver and might be more difficult to properly setup.
