3 Device Number Needed:
Data Source Part:
NDS3224V Number=12/12=1 piece (12 HDMI)
DVB-(T) RF output Part
By using 64QAM, 8MHz, each DVB-(T) frequency can transfer around 38Mpbs.
Each HD H.265 channel takes 3Mbps, while HD H.264 program takes 5.5 Mbps.
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=12/12=1 frequency
The number of HD H.264 channels carried by each frequency =38/5.5=6.9=7 Programs/frequency
The frequency needed for HD H.264 channels=80/7=11.4=11 frequency
So, total frequency needed is 1+11=12
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 12/10=1.2=2 sets.
