Will the LED TV work which I bought in US??

Hi Guys,
I bought an Samsung Full HD LED TV in US two years before. Now I am planning to take it to India. Will it work with Reliance HD DTH service?? My friend told it's NTSC system in US. In India, it's PAL system. So I may need to buy NTSC-PAL converter. Please reply me on this as soon as posssible.

If things are not working out, I have to buy a TV in India itself.

Thanks,
Sathya.
