Two things to consider which will answer this question.1. The voltage source must be if set from USA 110-120 volts out of the wall outlet (I think it will be but check) and if not you will need a converter that converts that voltage to the USA voltage.2. Since the transmission format in USA is NTSC and it is PAL there you will need a set top box that converts PAL to NTSC.( Google PAL to NTSC converter to see those.)Thats it.
