3 Devices Number Needed:
Data Source Part:
NDS3224V Number=92/12=7.6=7 pieces (12 HDMI) + 1 piece (8 HDMI)
NDS3565H Number=80/1=80 Pieces
DVB-(T) RF output Part:
By using 64QAM, 8MHz, each DVB-(T) frequency can transfer around 38Mpbs.
Each HD H.265 channel takes 3Mbps
The number of HD H.265 channels carried by each frequency=38/3=12.6 =12 Programs/frequency
The frequency needed for HD H.265 channels=92/12=7.6=7 frequency (if some channels can set lower bitrate like 2.5Mbps, 7 frequencies is enough to carry 92 HD channels.)
DVB-(T) Transmitter Part
Suppose the bandwidth for transmitter is 80MHz, and for DVB-(T) modulator is 8MHz, then one transmitter can max carry 80/8=10 Modulators. So the total number for transmitters is 7/10=0.7=1 set.
