[dvblast-devel] CA device addressing

[Kompan Kolia]

Sorry for repeating, but previous letter was in HTML format, and I don`t receive any comments.



Hello All :)

I have system with few TBS (TBS 6991SE) with two inputs.

This cards are made like two tuners on one board.
Each card consists of two tuners and two CI slots


After system boot in /dev/dvb folder looks like that:

/dev/dvb/adapter0:
total 0
crw-rw---T 1 root video 212, 53 Jul 13 17:25 ca0
crw-rw---T 1 root video 212, 50 Jul 13 17:25 demux0
crw-rw---T 1 root video 212, 51 Jul 13 17:25 dvr0
crw-rw---T 1 root video 212, 54 Jul 13 17:25 frontend0
crw-rw---T 1 root video 212, 52 Jul 13 17:25 net0

/dev/dvb/adapter1:
total 0
crw-rw---T 1 root video 212, 58 Jul 13 17:25 ca0
crw-rw---T 1 root video 212, 55 Jul 13 17:25 demux0
crw-rw---T 1 root video 212, 56 Jul 13 17:25 dvr0
crw-rw---T 1 root video 212, 59 Jul 13 17:25 frontend0
crw-rw---T 1 root video 212, 57 Jul 13 17:25 net0


We want to achieve following:

First instance of dvblast:
1 Receives encrypted DVB-S2 signal from the first input (/dev/dvb/adapter0/frontend0)
2 CA0 (/dev/dvb/adapter0/ca0) decrypts it.

Second instance of dvblast:
1 Receives encrypted DVB-S2 signal from the same FIRST input (/dev/dvb/adapter0/frontend0)  (the same transponder)
2 CA0 from second card (/dev/dvb/adapter1/ca0) decrypts it.

Third instance of dvblast:
Receives unencrypted FTA DVB-S2 signal from second input (/dev/dvb/adapter1/frontend0) from some other transponder.

We know about -y (--ca) feature, but it does not work for us, because second CA (adapter1/ca0) assigned to other DVB-tuner (adapter1) during boot.


Is there any solution or workaround for specifying input source for receive stream and CA to decode it. 

Example:

######### For First Input #################

dvblast  -a 0 -f xxxxx -s xxxxxx -v 13 -c /dvblast.cfg

------------ dvblast.cfg ------------

# Channel 1, /adapter0/frondend0, /adapter0/ca0

224.5.5.1:1234 1 216



# Channel 2, /adapter0/frondend0, /adapter1/ca0
224.5.5.2:1234/ca=/adapter1/ca0 1 217

------- end of dvblast.cfg ----------

######### END For First Input #################

######### For Second Input #################

dvblast  -a 0 -f xxxxx -s xxxxxx -v 13 -c /dvblast.cfg

------------ dvblast.cfg ------------
# Channel 1, /adapter1/frondend0

224.5.5.1:1234 0 210 

------- end of dvblast.cfg ----------

######### END For Second Input #################


or something else.


Thank for advise.
