Stacking multiple TV hats

Question

Is it possible to stack multiple TV hats on each other?

I would like multiple users to watch TV channels on different frequencies (MUXes).

But you can only decode one mux at a time. Even you can demux mux, there is only one HDMI output on Rpi. — tlfong01, Commented Aug 22, 2019 at 6:30
@tlfong01 I use raspi as a TV stream server -> hence multiple users can watch TV at same time. — Michal Foksa, Commented Aug 22, 2019 at 6:45
@tlfong01 Can you PLS explain what do you mean by Even you can demux mux ? — Michal Foksa, Commented Aug 22, 2019 at 6:47
Yes. I agree that you can use Rpi as a video stream server, therefore MULTIPLE users can watch the SAME VIDEO (say, same movie) at the SAME TIME. Now let me think aloud slowly. Suppose you can stack two TV HATs on one Rpi, and that one HAT decodes one mux (Movie A say) and the second HAT decodes another mux (Movie B say). Now you want your stream server to entertain two users, one user watching Movie A, and the other user watching Movie B. I am just guessing what you wish to do. Perhaps you can counter suggest what you wish to do. — tlfong01, Commented Aug 22, 2019 at 7:31
@tlfong01 That is 100% correct :) Generally I want my stream server to entertain multiple users, watching movies from multiple MUX-es. — Michal Foksa, Commented Aug 22, 2019 at 8:09

It's not possible because there's no way to change the SPI chip select pin from CE0.
