Help with satellites.xml values

In this example

Code

<transponder frequency="11330000" symbol_rate="9140000" polarization="0" fec_inner="3" system="1" modulation="2" onid="8916" tsid="1001" is_id="0" pls_code="174526" pls_mode="1"/>

Can someone tell me all of the possible values for is_id, pls_code and pls_mode and what they correspond to?

I am making a script that parses a satellites.xml file for a none enigma device, so I need to know how to translate them.

I have already successfully translated the other values I need.

Code

POLARIZATION = {"0": "H", "1": "V", "2": "L", "3": "R"}

FEC = {
    "0": "AUTO",
    "1": "1/2",
    "2": "2/3",
    "3": "3/4",
    "4": "5/6",
    "5": "7/8",
    "6": "8/9",
    "7": "3/5",
    "8": "4/5",
    "9": "9/10",
    "15": "NONE",
}

SYSTEM = {"0": "DVB-S", "1": "DVB-S2"}

MODULATION = {
    "0": "AUTO",
    "1": "QPSK",
    "2": "PSK/8",
    "3": "QAM/16",
    "4": "16APSK",
    "5": "32APSK",
}

Interesting, what device are you doing this for ? this is what i can find:

WHAT IS THE PLS CODE?

Physical Layer Scrambling or PLS is used in DVB-S2 as a form of low level encryption. A receiver will be unable to operate on a channel unless it is provided with the correct PLS code for that channel which can be Gold or Root.

WHAT ARE THE GOLD AND ROOT CODES?

The PLS code can be Gold or Root. In the world of mathematics they are two different types of binary sequence which have been widely used in telecommunications due to their particular properties. For us earthlings they are simply two ways to enter a PLS.

Code

Satellite with multistream transponder :
flow parameters must be added:
 is_id pls_mode and pls_code

<transponder frequency = "11013000" symbol_rate = "30000000" polarization = "1" fec_inner = "7" system = "1" modulation = "2" is_id = "2" pls_mode = "1" pls_code = "131070" />


Ranges:
is_id = 0 - 255
pls_mode = 0 - Root, 1 - Gold, 2 - Combo
pls_code = 0 - 262142

Thanks.

So is_id and pls_code are literal values and pls_mode are as follows

Code

PLS_MODE = {"0": "ROOT", "1": "GOLD", "2": "COMBO"}

I'm making a script to add sats and muxes to TVHeadend.
