There's no reason to assume starlink works like a typical satellite, though. Digital video broadcast in particular is in one direction from geostationary orbit. Latency is on the order of several seconds due to all the forward error correction that's necessary to tolerate bit errors in reception. There's not really any need for a "multiple access" scheme because "channels" are statically allocated frequency bands.

I would think the radio technology in starlink should more closely resemble modern LTE and 5G cell networks, whether you want to call that CDMA, OFDM, or whatever the specific techniques these days are called.
