Which cables for the HT-P1200?

Hello…

Ive seriously considered to buy the HT-P1200 Homecinema-system from Samsung. I got an old sony system that doesnt use the digital sound and it worked okay… But with the new system i would like some digital sound. But does anyone know what i need to make that happen… Do i need some kind of input/output on my other devices other that the system itself to make it work? Does my TV need to have it or how does it work…?? :eek:
