Whilst I have zero hope to decrypt BISS2-CA, I thought it might be interesting to count how may entitled decoders there are for each feed. We can see this as the count of unique entitlement_key_id in the emm stream (pid 0x21 seems to be favoured for this).

First off need you to get to grips with BISS2-CA EMM parsing, and extract a complete payload_unit from the emm-pid/ts. Referencing the EBU specs and nautilus7's oscam-emu implementation thereof, I parsed it by hand as follows:
Code: 
00 
81 -> table_id
F
F 87 -> length 3,975 bytes follow
00 01 -> entitlement_session_id
C9 
1A -> section_number
5C -> last_section_number
00 EB -> onid
81 -> last_table_id
0 -> emm_cipher_type 0, entitlement_priv_data_loop 0
F F -> reserved
0 00 -> descriptor_length 0
4A 5A 78 05 9C 84 E1 22 -> entitlement_key_id

So there are typically 15 entitlement_key_id's (or targeted decoders) per payload unit. It shouldn't be too much work to filter the emm pid to determine how many entitled decoders there are per feed. That will be of no help to decrypting the thing, just a semi-interesting statistic.

For today's three BISS2-CA feeds, I could see some entitlement_key_id present in all three, others in only 2/3 (but that may be because my recordings were too short).

Yes this information is almost equal to none
Biss 2 system works with serial number and MAC address
Probably stronger than the new Tandberg system

Unfortunately, our hands are short on these systems except with very large investments and software assistance

Whilst I have zero hope to decrypt BISS2-CA, I thought it might be interesting to count how may entitled decoders there are for each feed. We can see this as the count of unique entitlement_key_id in the emm stream (pid 0x21 seems to be favoured for this).

First off need you to get to grips with BISS2-CA EMM parsing, and extract a complete payload_unit from the emm-pid/ts. Referencing the EBU specs and nautilus7's oscam-emu implementation thereof, I parsed it by hand as follows:
Code: 
00 
81 -> table_id
F
F 87 -> length 3,975 bytes follow
00 01 -> entitlement_session_id
C9 
1A -> section_number
5C -> last_section_number
00 EB -> onid
81 -> last_table_id
0 -> emm_cipher_type 0, entitlement_priv_data_loop 0
F F -> reserved
0 00 -> descriptor_length 0
4A 5A 78 05 9C 84 E1 22 -> entitlement_key_id

So there are typically 15 entitlement_key_id's (or targeted decoders) per payload unit. It shouldn't be too much work to filter the emm pid to determine how many entitled decoders there are per feed. That will be of no help to decrypting the thing, just a semi-interesting statistic.

For today's three BISS2-CA feeds, I could see some entitlement_key_id present in all three, others in only 2/3 (but that may be because my recordings were too short).

Rather than counting all the unique entitlement_key_ids, there's a quicker way to estimate the number of decoders with rights: the last_section_number indicates the size of the complete EMM carousel played out in a loop.

The Leipzig-Liverpool feed 7.0E 10964H50 14400 CRO-019 M1 MAIN has last_section_number 57h (running 00h-57h), so ~ 58h * 15 unique decoders, or around 1320 boxes. Seems high? Maybe some of these EMMs remove rights as well as add them?

For Barca-PSP at 7.0E 11048V00 14400 E387 FEED B P1 the number is ~1305. The other feed at 7.0E 11000H50 14400 E362 M4 Main has ~1680 entitlement_key_ids, but weirdly the section_number doesn't increment as they are played out.

E362 is the Barca-PSG match, whilst E387 was a test for tomorrow's Porto-Juventus. Seems the Barca - PSG match has attracted more takers for the feed :wink:

Those are too high numbers for entitled decoders, aren't they?

Yes, the number seems high as I had commented. From memory they are similar to those seen on the free-of-rights regular Monday EBU Biss2-CA test transmissions.

I'm speculating, but I would assume there is some redundancy ie multiple decoders per subscriber, so as to ensure continuity of coverage in case of hardware failures from dish right through to decoder. And some of the EMMs may be used to deny rights. Who knows...?

BISS2 is no longer static, you need EMM to receive keys during the entire transmission
try to see how often the ECM changes

Try splitting 52gb file into 10 5,2gb files and search each one individually.
When found C8, split the 5gb file into smaller parts and repeat, continue until file size reduced to minimal. Then explore with hexviewer and tools..
