@Karthick_king bro, I think Measat 3B Satellite have 48 Ku band TP's,Currently only 5 TP's in Measat 3B Using by Sun Direct, If Sun Direct will get 7 More TP's in Measat 3B Sun Direct will have Total 12 TP's in Measat 3B & if they get remaining 5 TP's in GSAT 15(Currently 4 TP's in GSAT 15 using by Sun Direct )Sun Direct will have Total 9 TP's in GSAT 15 thus Sun Direct will have 12 TP's in Measat 3B & 9 TP's in GSAT 15,Total 12+9=21 TP's, Then Sun Direct can able to add more SD & HD 'Channels!
