Wait for some more time buddy let the new broadcaster bouquets be made available by Airtel Digital TV and other operators to their customers.
Airtel Digital TV is infact quite good in crafting affordable curated DPO packs. You may be wanting them to create a discounted DPO bouquet which contains just English GEC, English Movies, Sports, Infotainment by combining such broadcaster bouquet or A-La-Carte channels available from different broadcasters but i believe broadcasters themselves would not be wanting such a thing to be done by operators and rather want operators to push maximum channels in such Low NCF/ discounted DPO bouquets. This is why u will see operators only providing discounts on DPO bouquets and not when customer opts for creating own pack by mixing different broadcaster bouquets, a-la-carte channels and Add On Packs provided by operators.
Even if Airtel creates such Add On Packs by combining say broadcaster bouquets like Star Premium Prime or other such bouquet from different broadcasters which offers English, Infotainment, Sports channels channels then i am certain that there would not be any discount or just marginal discount provided on overall price of a pack. Also i am not even sure if operators can create Add On Packs by including broadcaster bouquets in it, i think it is not allowed and only a-la-carte channels can be combined to create DPO Add On Packs or Top Ups. I have already explained in above paragraph why such a DPO bouquet would be difficult to find by.
Lastly for niche or premium sports channels operators tend to provide less discounts as these cater to an audience base which have more purchasing power. But anyways all i can say is that on some decisions operators cannot take a decision on its own, they need to take broadcasters into confidence before implementing such things. In my opinion broadcasters and operators should allow providing such bouquets to customers rather than being insecure of losing out on subscriptions or ad revenue. Give subscribers choice to opt for channels they want to, same ways broadcasters need to provide a-la-carte channels at affordable pricing rather than keeping th high and giving heavy discount on broadcaster bouquet so that people find a-la-carte option unattractive.
Also since u said that other operators provided such curated packs which Airtel Digital TV did not, can u please quote few of such examples. Thanks
