Naa d2h picture quality is the best in both hd and sd but problem is lack of availability of all channels
HD : D2h =Airtel > DishTV > tataplay
SD: d2h > DishTV > tataplay > Airtel
Whether anyone agrees or not, despite highest tp in TP , they are compressing audio and video quality too much ..
One can easily see DD+ removed from almost all channels
I respectfully disagree on the part of ur statement where u rate Picture Quality of Standard Channels available on Airtel Digital TV to be poor, in all honestly 98% of SD channels have excellent transmission quality on Airtel Digital TV while 1% r available in bad picture quality from broadcaster end while yes rest 1% channels have average picture quality an can be improved..... Airtel has far superior picture quality than Dish d2h and even Tata Play where pixelation may be less visible as Tata Play uses deblocking to smoothen picture/frames thereby reducing sharpness.....also colors reproduction across channels available on Airtel Digital TV is far superior and so is the Audio Quality.
Lastly disgh d2h provides very less number of channels compared to Airtel Digital TV hence one cannot even have a relative comparison among them bcoz for fewer channels operator can allocate more bandwidth to each channel still Dish d2h picture quality is not so good across most channels compared to Airtel Digital TV....Tata Play has so much spare satellite bandwidth but again unfortunately still putting in more compression on many channels thus resulting in average or below average picture + audio quality
