SBD75e Series Demodulator Installation and Operation Manual
Selecting this mode overrides the ISI received in the base-band header, and all 16APSK rate 2/3
frames will be treated as though ISI is set to 1. In this example, the user must ensure that only one
stream (ISI 1) is transmitted using 16APSK rate 2/3. Failure to do this will result in output interface
malfunction, as two or more streams become incorrectly aggregated. In this case a warning
message at the bottom of the window (as shown in Figure 4.42) is displayed.
Note
ALL output stages must be programmed to a specific ‘Modulation and Coding’ value in order for
stream isolation to be effective.
4.9.5.6 DVB-S De-concentration
In DVB-S there is a method of de-concentrating multiple transport streams. In total two individual
transport streams can de-multiplexed from a bundle of 31. To enable this mode select
Deconcentrate.
Figure 4. 43 De-Concentration control
For each output (0, 1, 2), A valid Stream ID between 1 and 31 is entered. This stream is then
output on that port. There can be two unique outputs and the other is a copy of one of the other
two. Output 3 is always a copy of output 0. If all 3 outputs are unique then configuration will fail
and this will clearly be stated.
This mode is only valid in DVB-S and DVB-DSNG and not in DVB-S2 as it is now part of the
standard.
