I bought TATA Sky about 10-12 years ago. First time I saw that much clarity in my TV. The number of channels were too much and are specified in different categories. AT that time its service and signal quality were too good that I never found any digital connection as good as TATA Sky. But after subscribing to its HD set of box the signal quality decreases as compare to past. But still service is good and facilities and picture qualities are good as compare to other digital networks.
