Appearently, they are using a hybrid solution with IP-multicast encapsulated to MPEG-TS stream. I only found this specification: https://www.google.com/search?q=ip+multicast+encapsulation+over+dvb-s2&oq=ietf+ip+multicast+encapsulation+over+dvb-s2 but we need to check, if this type of the encapsulation is used.

PAT table:

2018-10-09 11:01:31.620 [  DEBUG]:tbl-base: pat:  nit on pid 0010 (16)

2018-10-09 11:01:31.620 [  DEBUG]:tbl-base: pat:  sid 00B7 (183) on pid 0BB8 (3000)

The PMT for sid 000A contains:

The PMT for sid 00B7 contains (perhaps stream with metadata?):
