My Sammy Smart TV is a few years old now but has Freeview built in along with Freesat also so just take a Sky dish etc cable and stick it in the back without the need for a Freesat box. Only one input, though I believe it can record TV if you attach a USB drive to the TV.
The actual Smart TV part has the usual bunch of Smart Hub apps Samsung offer. Including iPlayer, ITV Hub, 4oD, Five, Netflix, Amazon, Red Bull, Plex (handy if you have a NAS with a Plex server for streaming your own files), and a load of others.
Not amazing amount of grunt from the processor for the Smart Hub stuff and that’s considering I went for a model with more processing power. Main niggle is Amazon app being sluggish and audio when set to Dolby Digital occasionally drops out. A known issue.
I’m tempted to get an Amazon Fire stick or box for the streaming stuff with a lot more power and buffering, more app selection.
Anyway, what features you get though will very much depend on the model.
