All fairly self explanitory:
Arial in: there for connecting to your arial
Arial out: allows you to propagate the RF signal to another device, eg the TV, to enalbe this connection you need to enable RF Passthrough on the youview box
TV SCART: a SCART connector for passing the video/audio signal to your TV, generally for compatibility with older TVs that do not have HDMI
SPDIF: a digital audio output, allowing you to pass the audio signal to a compatible Amp/Hi-fi system. Personally I take my sound source from the TV set to the external sound system as that is then common for all inputs to theTV and not just the youview box.
Ethernet: The boxes link to the ethernet, for catch-up etc
USB: Side and back of the youview box are (currently) unsed USB ports
Power: The power supply for the box.
Some unused USB ports can be utilised for charging mobile devices / running a USB fan / lights & much much more
There was a thread that detailed a lot more devices a good while ago
There is no harm in trying to charge your phone to see if power is goint to the USB port
Found this one, but not the one I was looking for
Just by using the USB sockets on your TV, settop box, youview, DVD > player or recorder, router etc
List your ideas or alternatives here
