Need help

I need to insert information on DVB-C channel parameters
338 MHz QAM 256 SR 6875 FEC_outer 204 FEC_inner 188

In what format (Hz, kHz, MHz, hexadecimal or decimal) , it is necessary to inscribe these values in section

transport_stream_cable_descriptor(
frequency = ???,
FEC_outer = ???,
modulation = ???, # 256 QAM
symbol_rate = ???,
FEC_inner = ???,
),

There is a link to full syntax of NIT table in OpenCaster?

Thanks.

You may read http://www.avalpa.com/forum/viewtopic.php?f=11&t=16 wich contain a good example for what you need.

I think

transport_stream_cable_descriptor(
frequency = 0x033800000,
FEC_outer = 0x00CC,
modulation = 0x05, # 0x01=16QAM, 0x02=32QAM, 0x03=64QAM ... etc
symbol_rate = 0x0068750,
FEC_inner = 0x00BC,
),

should work for you.

Code:
                       transport_stream_cable_descriptor(
               frequency = 50724864, # 306.000
               FEC_outer = 0x0000,
               modulation = 0x03,
               symbol_rate = 430080, # 6900
               FEC_inner = 0x0000,
            ),

...

                               transport_stream_cable_descriptor(
               frequency = 51642368, # 314.000
               FEC_outer = 0x0000,
               modulation = 0x03,
               symbol_rate = 430080, # 6900
               FEC_inner = 0x0000,
            ),
