[linux-dvb] Can't record an encrypted channel and watch another in the same bouquet. (also teletext doesn't work for encrypted channels)

[Simon Siemonsma]

I have a problem with encrypted channels.
I have a Conax CAM Module (by Smit)
Further I use a Technotrend T1500 Budget card with CI cart.

With FTA channels everything works just fine.
With encoded channels some things don't work.

I can't record one channel and at the same time look at another channel from 
the same bouquet. (Kaffeine says: "no CAM free", vdr says: "Channel not 
available"
Teletext doesn't work (vdr says: "Page 100-00 not found")
When I start vdr I get the following in the log file:
"CAM 1: module present
CAM 1: module ready
Conax Conditional Access, 01, CAFE, BABE
CAM 1: doesn't reply to QUERY - only a single channel can be decrypted"

This looks like the CAM can't just encode one channel at a time.

But on the dvbshop Website they say:
http://www.dvbshop.net/product_info.php/info/p2194_Conax-CAM--Rev--1-2----4-00e-by-Smit.html
"MPEG DEMUX: Multi-channel SECTION and PID filter configurable through 
software"
in vdr's CAM menu is stated: "Number of sessions: 5"

This looks like the CAM can handle multiple channels at a time isn't it?

Someone at 
http://www.dvbnetwork.de/index.php?option=com_fireboard&Itemid=27&func=view&catid=2&id=6191#6192 
(German) pointed me in the direction of the linux drivers.

Is he right?

I understood from 
http://www.linuxtv.org/docs/dvbapi/Introduction.html#SECTION00230000000000000000 
that the CAM comes before the Demuxer and: "The complete TS is passed through 
the CA hardware".
If I understood this right this means that onces I watch one channel in a 
bouquet the complets TS is decrypted. So all other channels and teletext are 
decrypted too. This makes it extra confusing why I can't record one channel 
and watch another in the same bouquet.
Do I understand it wrong or are the drivers or the dvb software not mature 
enough yet.
I use kernel 2.6.25.

Only Kaffeine 0.8.7 support multiservices cam.

Yes.

No, the whole TS isn't decrypted. Only one (or more, if your cam can do more) 
service(s).

Most probably your cam is only able to decrypt one service at a time.

Hi,
I have an AstonCrypt which is able to decode 2 services at the same 
time and it works beautifully with mythtv (I have a TT 32000 but the CI 
is the same and I had a 1500 and I think, but I am not sure, that it 
worked also with it).
HTH
Bye

Hello,
I think this is your issue

I have a PowerCam Pro and I succed to send at least 5 channels at the
same time to it (as far as I remember, it supports 16 channels)

Hope this will help

Everyone thanks for their answers.
I understood:
-my cam can just decode one channel at a time. Only some expensive cams can do 
multiple channels.
-teletext is encrypted in the Netherlands while it normaly shouldn't.

I decided to give vdr-sc (softcam) a try combined with a cardreader.
This seems to be the only reasonable solution to me.

It should at least make it possible to use multipe encrypted channels.

Thanks,

Simon Siemonsma

I don't think so -- I've had no problems viewing NOS-text with
a FTA receiver -- if you could give me names of particular
channels from which you want to view ttx, I can check at
19E2 or 23E5 (DVB-S).

It could be that some subscription services do encrypt the
teletext, as I've seen that with a few other channels.

I understand you are saying that teletext is not encrypted on satelite 
broadcasting aimed for the Netherlands.
P. van Gaans understood from my problems that I must be living in the 
Netherlands. As teletext on Digitenne is encrypted contrary to what is 
normally done.
So you are talking about DVB-S (Canal digital) while I'm talking about DVB-T 
(Digitenne).

You likely live in The Netherlands. Teletext on Digitenne is encrypted, 
and you are not the only one with problems. The teletext simply 
shouldn't be encrypted, but we can't control KPN. In some cases this can 
be solved by changing settings in the CAM menu.

When saying the whole transport stream goes to the CAM, this means 
everything connected to the requested service ID gets decrypted (if the 
CAM is capable). So not just audio and video, but also extra audio 
tracks, teletext etc.

To descramble multiple channels you usually need a more expensive CAM. 
For example 
http://www.made-in-china.com/china-products/productviewJqSxvLmUREWp/Professional-Irdeto-CI-Module.html 
shows a "professional Irdeto CAM" that will descramble 4 TV channels at 
the same time. Not usefull for you because you need Conax, but I don't 
know which Conax module could descamble multiple channels.

This is no linux-DVB problem.
