I have taken a HD DTH connection from Airtel and that was installed the next day after making payment over the internet. I had enjoyed watching the NatGeo HD channel. I had plugged it to Onkyo AV receiver to get the best quality picture and surround sound through HDMI and Digitial Optical Fibre cables and it was truely Dolby Digital experience. I am waiting for Airtel to get more HD channel for its customers.
Firstly the viewers need to know that we have only 2 or 3 channels on HD and only very few programs transmitted on HD.... and if you are ready to spend a good amount to enjoy the HD experience only then you step into it. Since you are spending much ahead of times in India.
Else, you can wait when the costs come down...... till demand and supply meet.
