The best way is one HDMI cable from your TV to a home cinema amp and plug all your source devices into your amp using your amp as a switching device and relegating your TV to a basic monitor. Then you can plug whatever source devices into your amp as you see fit….Sky box or freesat/free view box, Apple TV or similar device, Blu Ray, games consoles etc…the world is your oyster. You also relegate all your remotes to one as most home cinema amps come with programmable remotes. Nice and neat for cables too as you havn’t got a spaghetti junction of cables going to your TV.
Edit, sorry thought you were talking about connecting everything up. You just need to get a satellite and aerial cable to it, assuming all your Internet streaming stuff is via WiFi. Unfortunately in my set up I forgot about this and had to resort to running cables outside the house and drilling through the wall.
