First condition- That 66% is also a condition like Sony Six costs Rs. 40 in A-La-Carte so in bouquet its rate can't be lesz than 66% of Rs. 40.
Second Condition- Also if a package has 100 chs and it costs Rs. 240 then sum of A-La-Carte prices of all these 100 chs present in that package can't be more than three times of Rs. 240 which is the package price .
Third Condition - If RIO rate offered by a broadcaster for X channel is Rs. 10 then DTH can't offer it at more than Rs. 20 in a-la-carte.
All these conditions need to bw met. So u will see major changes in packages plua pricing. This is why time till April 1 has been given
Hope u understood now
