Caution!
The number of programs that the MLF-101 is able to distribute depends on the resolution (SD, HD, 4K etc.), the
compression (MPEG2, H.264 etc…) and in general from the total bitrate of each program.
For example, if we select the following DVB-T setting for the four modulators on MLF-101 outputs:
• Constellation: 64 QAM
• Guard Interval: 1/32
• Code rate: 7/8
• Bandwidth: 8 MHz
According to Appendix A we will have a total output bitrate of 31.67Mbps/ modulator. That means that we can
select as many programs as the user wants but their total bitrate must not exceed the 31.67Mbps, otherwise artifacts
may occur.
The status section in (Figure No 9) provides a general idea to the user of the current payload (according to the
selected programs) comparing it to the max. output payload.
It is recommended that the user must not exceed the 85% from each output, since all the bitrate are variable
according to their specific content.
Using the Drop-down menu from “Output” column (Figure No 8) the user is able to assign any program to any of
the four outputs. By doing the same process for each program, from all inputs the user is able to create his own 4
custom multiplex in the output.
