It's certainly possible to build non-causal signal processors for broadcast TV by using multiple tuners that buffer channel N+1 while you're watching channel N. You could do it for streaming services too by using statistics (or--dare I say it--AI) to predict what movie the user is most likely to sample next.
It might make the decoder cost an extra $2, and that's probably why nobody does it.

Ultimately the problem is that with old analog signals you just needed to wait for the next V-Blank (4 hundreds of a second at the most) and you were good to go. With digital signals you need to wait for the I frame which can take dozens or hundreds of frames. And this assumes you have a good solid signal and can decode everything perfectly, if the set is trying to piece together a fragmentary signal it's even harder.
