This is my opinion
in this case we know to trai tariff
regulation
Why star and airtel against trai
Trai order say channel price is uniform for all distribution platform.
Trai order before star give large amount of discount for airtel to add their channel in base packs
Trai tariff regulation after trai fixed maximum channel as 19 rs. So hd channel price come down. U check star hd channel rate after and before trai order.
My view star decrease discount price for hd channel that why problem started.in star advt they show about
hd channel price
Example
Trai before
Vijay hd -25
Trai after
Vijay hd -19
