How to lock MIS/PLS stream from 5w

Hi all

Some users ask us how to lock the MIS/PLS stream from 5w ,as it need soft support too we can take dvblast for example

the orignal version do not support MIS need a small patch like this:

here is how to fix DVBlast - it needs 2 lines patched to support MIS/PLS
properly. so, in source code file:

https://github.com/gfto/dvblast/blob/master/dvb.c

the following changes needs to be done:

===
#define DTV_STREAM_ID 42

must be:

#define DTV_STREAM_ID 43
===

and

===
#define MIS 9

needs to be:

#define MIS 8
===


please, note that after you have fixed DVBlast, then the most common
reason for problems are that some websites published wrong information -
for example let's take 11012V transponder of RAI on 5W:

http://www.flysat.com/e5wa.php

according to the information published there:

* Input Steam ID (ISI) of 2 is not using PLS, if that information is
used it fails, as the information is wrong

* same as ISI 2, there is no PLS for ISI 3, if that information is used
it fails, as the information is wrong

* ISI of 11, which is 0x0b in hexadecimal is using PLS of 16416, which
is 0x4020 in hexadecimal and that means in Linux 0x40200b should be passed

so, why ISI 2 and 3 are not working - simply they use the same PLS of
16416, even the websites explicitly state is not that. so, MIS/PLS value
is "0x402003" and it's the working setting. here are the DVBlast command
lines as example:

./dvblast -f 11012000 -s 30000000 -v 13 -m psk_8 -1 0x40200b

./dvblast -f 11012000 -s 30000000 -v 13 -m psk_8 -1 0x402002

./dvblast -f 11012000 -s 30000000 -v 13 -m psk_8 -1 0x402003

in general all TPs with Multistream of RAI on 5W are with such mistake -
the rest listed on Flysat don't mention PLS at all, but they all use
that PLS of 16416. so, always 0x40200x needs to be use for them, where X
is the ISI - all ISIs are correct on Flysat list.

Mediaset TPs on 5W information on Flysat is correct - they all use PLS
of 8 - as example let's take 12585V i and then the "-1" value to be
passed on DVBlast command line is 0x801 f or ISI 1 or 0x802 for ISI 2.

last interesting example for 5W is 12648V:

it uses not "root" type of PLS, but "gold type of PLS. so, the ID should
be 0x4 for the gold code, then combined with 0x1d97c for the PLS and
then 1 for the ISI or 0x5d97c01 combined, that means:

./dvblast -f 12648000 -s 29500000 -v 13 -m psk_8 -1 0x5d97c01

more question please feel free to ask us.

Thanks

Kind Regards

Thanks for the explanation !
can you explain more how to combine the gold id 0x4 with pls code?
I understood that's need to add 0x40000 to the pls code so if you have pls code 0x5 it will be 0x40005, is that correct?
and for pls type combo how i can do?
