ATV G2 uses HDMI connections, and yes it can be controlled via a PUC (as Apple Remote)
The real question for you, is how many HDMI devices do you want to support, and how many HDMI connections does a BV7-40 Mk II have
That is your real constraint
If not enough HDMIs you need to look at the ATV G1 (in my opinion)
First B&O (1976) was a Beogram 1500 ... latest (2011) change has been to couple the BL11 with the BL6Ks *sounds superb*
