Hi,

I have recently bought a Samsung Smart TV and added it to my BT Set Top Box & Sony DVD Player.

I wired as follows:

Ethernet cable into BT box. Rooftop aerial cable into BT box, then daisy chain that RF cable into the Sony and then into the TV.
I connected the BT box to the TV with an HDMI and I also connected the Sony to the TV with an HDMI.

Is this correct? Do I need the RF running into the three boxes?
Do I need both the RF and HDMI cables? (If I do, why? Am I misunderstanding what signals are running through the HDMI).

Thanks for any advice.

Regards,
