I didn’t have much much with iptv as it buffers a lot and it’s not because of my broadband speed, I already have a satellite dish on my house and was thinking about making the use of it but I don’t know where to start.

I’m assuming I need to get a special box, maybe like this? https://www.ebay.co.uk/itm/354681753333?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=QTcb7QRmQpO&sssrc=4429486&ssuid=2LCMph_nQpa&var=&widget_ver=artemis&media=COPY

But then I wouldn’t know what to do with it, do I need to get some decryption keys from somewhere every few weeks?
