Caution!!!
● Modulation settings must be applied with care and in order to have adequate output bitrate. The output bitrate
(which can be
calculated from the tables in Appendix B) must be equal or greater than the total sum of the bitrate of the encoders.
Example
: Assuming we select the following modulation settings:
Modulation:
8K
Constellation:
16-QAM
Code Rate:
5/6
Guard Interval:
1/32
Bandwidth:
8 MHz
We have an output bitrate of
20.107 Mbps
according to Appendix B.
This means that encoder’s bitrate must be adjusted in such a way that the total bitrate of the encoder does not exceed the
20.107 Mbps limit, otherwise artifacts may occur.
For example
, one valid selection in case of four encoders would be to set each encoder bitrate to 5 Mbps since:
4 x 5 Μbps = 20 Mbps < 20.107 Mbps
* TS ID must always be different between DVB-T modulators in the same network.
