Income of dth operators depend on No: of subscribers they have and not on how many pay channels we subscribe. Till now they earn more income if we subscribe more channels. But from now ownwards they will earn same ncf from all subscribers. The whole money we spend on pay channels will go to broadcasters and GST. They won't earn extra income unless they start charging NCF for additional channels.
They will get more subscribers if they provide better services, free pay channels within basic pack and discounts in NCF. More subscribers means more income. If they can't provide professional and interactive services like other operators then they will have to provide more discounts to attract subscribers.
