neumoDVB does not (yet) come with a list of predefined muxes. Instead you will need to define at least one mux per satellite yourself and then scan that mux. Usually this leads to the discovery of most if not all muxes on that satellite.
Using spectrum blindscan
most of this process can be fully automated. However in this section
we will follow a more traditional approach and just enter tuning data. Even in this case, installing
the blindscan drivers has some advantages: with these drivers, only the frequency and the polarization
need to be specified (with the exception of special muxes, such as multi-streams and T2MI streams).
Other parameters will be found by the driver.
Use Lists - DVBS muxes
to enter the mux screen and CTRL-N
to add a new line.
The fields to complete are:
Sat.
Editable The satellite position. The popup list allows only predefined satellite positions to be selected. You can extend or edit that list elsewhere (Lists - satellites
).Frequency.
Editable The value is in units of Mhz, but you can add a decimal fraction for higher precision. This can be essential to lock low bitrate transpondersPol.
Editable PolarisationSystem.
Editable Set toAuto
for blindscan orDVBS
orDVBS2
Symbol Rate.
Editable The symbol rate is kS/s. You can enter decimal fractions for higher precision (rarely needed). If blindscan is supported, there is no need to enter a value here. However, for difficult to lock muxes, entering a value close to the correct one will facilitate tuning. Specifically, when tuning to low bit rate transponders, enter a low value here.PLS Mode
andPls Code.
Editable physical scrambling parameters, often needed for multi-streams. You can get the values on the internet. If the blindscan drivers are installed, the values will be found automatically in typical cases, but this is not always true. Thepositioner
dialog also allows searching the correct value, but this can take hours and is not 100% reliable.FEC
: Editable Forward Error Correction. Almost never needs to be set.stream.
Editable the stream id of a multi-stream. If a mux contains multiple streams, then neumoDVB considers each stream as a separate mux.t2mi-pid
: Editable The pid containing an embedded DVB-T stream on this mux; leave blank. A single mux can contain multiple such streams. neumoDVB does not directly tune to those streams, but rather to the main transport stream. If it discovers embedded DVB-T stream it will create additional mux entries, which will be distinguished by thet2mi-pid
value. In many cases, the streams are not properly described in t
