As poited out by Fujisawa san during the BoF, it is a violation of
STD5, RFC1112:

:7.3. Extensions to the Local Network Service Interface

:   The local network module must not deliver up any multicast packets
:   that were transmitted from that module; loopback of multicasts is
:   handled at the IP layer or higher.

to expect filtering at the IP layer or higher.

I think we must modify either the DVB encapsulation or STD5.
