Tata Sky is one of the most tv channel provider in interior are also. I am using Tata sky last five years. But we can not find trouble during this time period. Its picture quality is very good and mpeg. It is also available in hd also. The sound quality is also very good it is stereo. We can pay money for those channels which we like. The service of tata sky is very good after only one call its executive come to the home and installed it and its support are very good. The value for money is 5/5 for Tata Sky.
