You need an HDMI to RCA converter cable which looks like this:
Although I'm not sure how good this wire will work because HDMI is digital while the RCA is analogue and has been around since the VCR days!
So, your best best is to buy an adapter, which is going to be expensive than a cable (Rs.1,000 to Rs. 1,500), but it'll have better picture quality and overall reliability if you intend to watch full HD videos. .
Hope it helps!
