The product page of Beoworld gives better details than the B&O site !
http://www.beoworld.org/prod_details.asp?pid=1276
It states that the BV10 connections include:
- Digital audio inputs 1 x Phono SPDIF 1
You need to find the similar connection on your sky HD box.
Or are you saying you are not sure which physical position on the units to plug the cable in ?
[update]
I downloaded the BV10 User Guide from Beoworld (I am a Gold member) ... look on page 40 of your User Guide manual for the connections ... you should have received this manual with your system.

First B&O (1976) was a Beogram 1500 ... latest (2011) change has been to couple the BL11 with the BL6Ks *sounds superb*
