I have installed Tata sky in 2010. Now the HD and SD versions are available. You can select different channels. Service of Tata sky is nice, you can chat in chat section with customer care. Picture quality with LCD/LED Tv is very nice. And sound quality is very nice. If you recharge Tata Sky monthly in tata sky site than you can get free gift voucher. In menu bar you can see weekly program schedule also.
