There is no competition on TPs but competitions are on channel additions, if dishtv uses 21 + TPs then doesn't matter every DTH should have 21 + TPs. Biggest things which matters are channels, if d2h can be future ready with 12 + 13 TPs then what TS have to do with 20 + TPs ?
I know SATs having different configurations but if TS having latest technology can hold 50 + SD channels in 1 TP then whats the problem. I already said and having firm belief no matter whosoever thinks what, TS will never increase channels no. they will always have 350 to 400 + SD channels and since many premium peoples don't like to see SD channels then why we keep on praying infront of God and expecting TS to add more SD channels ? They can easily have 400 + SD channels at 7 TPs.
Rest left 3 TPs so again they're far away from other DTH currently they providing 13 HD channels then 13 * 3 TPs = 39 HD channels, and they don't even have this much currently. For 2 - 3 years this capacity is enough.
2 TPs for UHD which have HEVC compression currently we have no UHD channels and as I said don't expect plenty in 4 - 5 years. Even in next 10 years if we have more UHD channels then atleast TS will have the capacity of 12 4K channels in 2 TPs.
If TS migrates to HEVC compression in HD channels also then with that they can add 10 more HD channels in 3 TPs means 49 HD channels. Which they never add even if this much HD channels launches in India.
Regarding space are we sure that ISRO didn't planned any backup SAT of Insat 4A ? Once it got expired then what will happen to the operation which are conducting from Insat 4A ?
