DVB-(T) output Part
Suppose each frequency can transfer 32Mpbs (64 QAM). Each SD H.264 program takes 1.7Mbps, while HD H.264 program takes 6 Mbps.
The number of SD H.264 per frequency=32/1.7=18.82=18
The number of HD H.264 per frequency=32/6=5.33=5
The frequency needed for SD H.264 program=40/18=2.22=3 frequency
The frequency needed for HD H.264 program=10/5=2 frequency
The total output frequency=3+2=5 frequency (I.E. 5 DVB-T2 Modulators)
