Hi
Below is my opinion having used tata sky hd and airtel hd:
Pic quality for HD:
Airtel gives more clarity and look natural with good sharpness
Tatasky compress HD pictures which is quite evident when you see scenes which the camera moves. If younare kind of videophile more towards attention to detail then you would see pixels in HD tatasky hd. Sharpness is less and you see softness in the picture of tatasky hd. Many people fall for this gimmick thinking tata sky hd pic quality is awesome.
Tv used for comparison: Sony full hd 48 inches
Audio:
Dolby digital
Here too TAta sky sound in Hd channels is very bassy and no clarity. Airtel sound is more natural and good clarity on dolby digital. It certainly gives a natural effect.
i feel tata sky uses some back ground processing on audio whereas in airtel the sound is raw(meaning more natural, just like how the original content is supposed to be heard).
Home theater used for comparsion:
Pioneer vsx-530
Hd channel count:
Tata sky is way head in this area with maximum hd channels
Hardware:
I used the tata sky transfer + box and needless to the the tata sky box looks premium with the remote
Customer care:
Tata sky is ahead in this area.
Cost:
Airtel is cheaper. HD channels package is cheaper and reasonable compared to tata sky
Note:
I changed from tatasky to airtel just for the hd picture quality. If you are more concerned about hd picture quality and cost, go with airtel hd. If number of hd channels is your concern, then tata sky is better
