as per this pdf two tp ie 11490 and 11570 will beam 18 channel each
currently they are beaming 10 channel each and other 3 tp no change in channel nos..........
i think it will take more than 6 month to commission this upgradation
they will not change it to mpeg 4 DVB S2 that bad.............
if they change fully system of 4 and 5 tp then they should have used it for mpeg 4 DVB S2 then they could have added more channel about 24 to 30 per tp
