I'm unable to find your details to confirm the TV Box you have but @Ernie_C is correct in that a HDMI cable can be used to connect it to your Samsung TV. If you have any problems with it, please let us know.
I can see that the TV Onebox is HDMI, but the Virgin box appears to be Scart.
My question is, can I use other ports to link the TV with the Virgin box? I was misled about what the TV could do and I wanted just gain Freeview Play but am unable to have an aerial fitted where I live. So I wanted to know the best cable connection that retains the Virgin Box with minimal cabling.
