How does satellite telephony work? Alice calls Bob over satellite. Alice's telephone is on AC power, and contains a GPU cluster, and Bob's is the same?
Today's GPU clusters is tomorrow's cell phone. But this codec doesn't require that much power anyway. I didn't try it but on some forum somebody claimed 0.5x speed on a Core(TM) i3-7100U CPU @ 2.40GHz [1]. It sounds plausible that with some more optimization and a bit better hardware, that's a bit more specialized for AI, it could do real time encoding and decoding on cell phones.
