I’m currently doing this while trialling flipping my lounge room around (haven’t run aerial cable to other side of room yet).
I’m doing it with a google tv dongle. It works quite well. The setup is a little painful because you have to download all the apps (abc, SBS, 7, 9, 10) and individually sign into each with your account. Each of the apps have “catch up” tv and also stream live tv option. I use a TV guide app to see what’s on then load up the appropriate channel.
I find google tv quite good for access to all your streaming services incl fta (Stan, Netflix, Disney are what I run at the moment ).
I have quite fast Internet (350mbps) and have no buffering issues. But don’t know how it would go with lower speed Internet.
