Yes, depending on your options you can use Toslink (digital optical — the little pentagonal connector with the red light), digital coaxial (brown RCA cable) or 5 red/white RCA-pairs to connect BD to HT (home theater).
I'm guessing you mean you have an HTIB (home theater in a box), so Toslink is your best bet. It is a pure digital transmission with zero electromagnetic interference (because it's literally pulses of light, not an electric signal carried over an inducible copper wire).
