Step 1: To convert a TP into completely MPEG4 with DVB-S2 8PSK modulation, they need to move at least 20-21 channels to MPEG4 and into single TP.
Step 2: Once those number of channels got migrated, they can convert channels on other TPs into MPEG4 and move them to this converted TP until a maximum of around 35 channels.
Step 3: The remaining channels in the second TP can also be converted to MPEG4 and that TP can be completely changed to DVB-S2 8PSK modulation.
Channel addition will happen after Step 2 and will be done in phased manner based on the TP space recovered.
This can go on until all TPs are converted to DVB-S2 8PSK modulation.
So we have to wait till at least 20+ channels are moved to MPEG4 before expecting any channel addition.
