Configuration
for
DVB-S2 Multistream Modulation
is similar to single stream settings with the
ability to add 6 streams to the modulation as shown in Figure 35 below.
Figure 35 SMD 963 multi-stream configuration
Multi-stream is supported in DVB-S2 CCM and VCM modes using the SMD910 modulator. Multi-
stream DVB-S2 CCM limits the modulation type and FEC to the same for all the streams. Multi-
stream DVB-S2 VCM as shown in Figure 35 allows a modulation type and FEC to be set for each
stream in the modulation.
Each input can be set to the desired incoming stream. If the input set to “OFF” the stream is not
configured to be used in the modulation. If the Input is set to something other than OFF and no
stream is present, an error indicating that input is missing is generated.
For each stream an Input Stream Identifier (ISI) is needed. This value is used by receivers to
select the appropriate stream out of the multi-stream modulation.
Note:
When in the Multi-stream Modulation mode, the input backup and TS Analysis features are
not available.
