  It's not implemented yet. You can however redirect the input of one
  tuner through the ci, so you can decrypt one
transponder.

Well this is not good news for users in germany because without a
working cam, you can't watch much channels with dvb-c.
Don't know but I can't understand, why cam
handling must be done in userspace for these new cards.c
And oscam doesn't support this? I feel softcam support to be much easier 
then a hardcam these days. As for driver support, you can of course ask 
Digital Devices if they can implement said feature of course :)


Having not found any user on DVB-S(2) and only one DVB-CT user on this 
list so far, I do feel there aren't many using these cards yet, hence 
the lack of support.

   I've a question for you Olivier. I don't know that brand. Why going to 1 
   dualtuner board and the octopus. In the same brand you can also use the 
   Cine S2 that could eventually be expended with a dualtuner board for 
   example. What are the limitation?
   From what I know, is that the hardware is nearly identical on both setups.
  
  The Cine S2 is an octopus with only 2 connectors (which allows 4 extra 
  tuners) and has 2 onboard tuners, so 6 tuners maximum.
  
  The Octopus is ONLY the bridge chip (in FPGA form strangly in the latest 
  revisions, was the nGene before, driver is the same so maybe they got 
  some IP from micronas to put in the FPGA due to performance/scaling 
  issues?) but has 4 connectors for expansion cards. So you can connect 8 

Micronas has nothing to do with the new bridge. nGene is no longer in production
and it also lacked inputs and outputs to support more tuners/CIs.

What could be supported, and this is not possible with any other DVB PCIe card

Oliver Schinagl wrote:
 Nevertheless, good to know that DVB-S2 on the ngene is well supported (I
guess ) :)

Yes it is, but it's a different device, so don't mix it. The kernel modules
ddbridge or ngene do represent the PCIe-Bridges, not the receiving
frontend.

ngene based cards have been the former devices, with less possibilities to
expand tuners, DVB-S2 only available and no CI support. The first versions
of these devices has been a PCIe PCB (V5.4 and prior) with just 2 DVB-S2
tuners and no connector for additional ones. The last version (V5.5) of
ngene based devices had also 2 DVB-S2 tuner and one connector for
additional 2x DVB-S2 (Flex-Modules). I'm running a V5.5 with 4x DVB-S2 in a
VDR since March 2011 connected to a SCR environment, perfect :-)

ddbridge did enhance the possibilities. There are two different solutions
out there, either the classic DVB-S2 dual-tuner PCIe similar to the V5.x
ones, called V6.x. This PCIe PCB do have two connectors for Flex-Modules,
which can be a single CI, dual CI, dual DVB-S2 or Dual DVB-C/T.
Alternatively there are or have been the bridges only (no tuners) available,
either as PCIe 1x PCB or mPCIe. AFAIK there has been two versions out, one
with 2 connectors, one with 4 connectors. With the last you could build a
VDR with up to 8 tuners connected to a single [m]PCIe card ...

The dual Flex-Modules of the V5.5 and V6.2 are interchangable, they are
bottomline the same, just normal product care over the time ...

I'm running also an L4M Dual DVB-S2 V5.4 (ngene) and a V6.2 (ddbridge) in
test and development maschines.

Well the interface to decrypt an incoming encrypted stream differs from

In this case vdr needs to support two diferent ci systems.
Sending an encrypted stream from memory back to ci and get the decrypted
stream is nice to have but not the main use case for a dvb card.
In vdr-portal.de are some posts that redirects using szap czap etc and a
ci works. Q: is there a working solution for vdr as well?

Re: [vdr] Digital Devices (Linux 4 Media) 4 port (8 tuner) octopus/Duoflex experiences

2012-11-27 Thread Timothy D. Lenz

I glanced at these boards because at one time I wanted to replace my old 
nexus card and I only want to use multi-tunner cards from now on. I 
could not afford any upgrades now though:(


But one thing I noticed is, they only support 8PASK modulation and not 
the others, 16/32. While they may not be used much now, if usage does 
pick up, then these cards are useless and the money wasted. If I had the 
money to spend on new tuner cards, I would hold out for one that covered 
the possible modulations better.

[vdr] Digital Devices (Linux 4 Media) 4 port (8 tuner) octopus/Duoflex experiences


Hey VDR friends,

I'm thinking of getting into the whole satellite thing (DVB-T user for 
now) and was searching for interesting DVB-S2 tuners. I found that the 
l4m octopus/duoflex-s2 a very interesting device. While expensive you 
can connect up to 8 tuners! to a single PCI-e 1x lane (Bandwith should 
be more then enough). While I know there is a octopus mini-pcie device, 
I heard that there where some PCB issues so decided on getting the PCI-e 
version.


I have tried googling for some up to date linux! information but found 
very little. Are there any l4m/dd octopus/duoflex DVB-S2 (or even 
CAM/DVB-C/DVB-T) users here that can share their current (and past) 
experiences? The tuner (only 1 dualtuner board and the octopus) will set 
you back a good 200Euro so I want to be sure that the devices is 
properly supported.


Thanks,

Oliver

I think you've already answered your question here.
Being an early adopter rarely pays off in the linux world, unless you have
the skills to troubleshoot the drivers yourself and enjoy doing so.
Having had such problems in the past with other devices, even if 200€/8
tuners sounds like a good deal it really depends on how much you value your
free time.
Also keep in mind that theoretically every tuner needs its own cable coming
from the dish, right now I have two of them and having 8 for me would be
impossible (if you want to make them go inside the walls through existing
pipes).
FYI, my vdr box is an old PIII 1000 with 2 DVB-S2 tuners and one DVB-T (all
of them PCI). I've been using it for about 4 years now.

I think you've already answered your question here.
Being an early adopter rarely pays off in the linux world, unless you 
have the skills to troubleshoot the drivers yourself and enjoy doing so.
The 'ddbridge' is already in the kernel. They claim on their site that 
it has linux support. Their linux4media site sells these specifically 
aimed at the linux market.


So in theory, it should work and should work well. But since there's so 
little results (price related?) under linux for this 2008 or so board, 
could be either really good (it works and works well) or nobody has 
bought it yet.
Having had such problems in the past with other devices, even if 
200EUR/8 tuners sounds like a good deal it really depends on how much 
you value your free time.
It's 200E for 2 tuners only. each additional 2 tuners is about 150E. So 
you  pay 50E for the 'base' board, without any tuner, and 150E for each 
dual-tuner tuner module, which can be either DVB-S2 or DVB-T/DVB-C.
Also keep in mind that theoretically every tuner needs its own cable 
coming from the dish, right now I have two of them and having 8 for me 
would be impossible (if you want to make them go inside the walls 
through existing pipes).
Well I don't even have a dish yet, but this would be for future upgrades 
of course. Yes running 8 wires through the wall is a lot, but manageable.
FYI, my vdr box is an old PIII 1000 with 2 DVB-S2 tuners and one DVB-T 
(all of them PCI). I've been using it for about 4 years now.

Hello,

I'm interested for such information. (I'm looking also for good well supported 
DVB-S2 device to target multiple satellite)

I've a question for you Olivier. I don't know that brand. Why going to 1 
dualtuner board and the octopus. In the same brand you can also use the Cine S2 
that could eventually be expended with a dualtuner board for example. What are 
the limitation?

From what I know, is that the hardware is nearly identical on both setups.

The Cine S2 is an octopus with only 2 connectors (which allows 4 extra 
tuners) and has 2 onboard tuners, so 6 tuners maximum.


The Octopus is ONLY the bridge chip (in FPGA form strangly in the latest 
revisions, was the nGene before, driver is the same so maybe they got 
some IP from micronas to put in the FPGA due to performance/scaling 
issues?) but has 4 connectors for expansion cards. So you can connect 8 
tuners maximally :)


That said, they also have a single/dual CI expansion module to go onto 1 
of those connectors, but I dare not to find out how their CI driver 
support is. Usually softcams work much better.



Regards,

Michael

experiences

Hey VDR friends,

I'm thinking of getting into the whole satellite thing (DVB-T user for
now) and was searching for interesting DVB-S2 tuners. I found that the l4m 
octopus/duoflex-s2 a very interesting device. While expensive you can connect 
up to 8 tuners! to a single PCI-e 1x lane (Bandwith should be more then 
enough). While I know there is a octopus mini-pcie device, I heard that there 
where some PCB issues so decided on getting the PCI-e version.

I have tried googling for some up to date linux! information but found very 
little. Are there any l4m/dd octopus/duoflex DVB-S2 (or even
CAM/DVB-C/DVB-T) users here that can share their current (and past) 
experiences? The tuner (only 1 dualtuner board and the octopus) will set you 
back a good 200Euro so I want to be sure that the devices is properly supported.

Thanks,

Oliver

Re: [vdr] Digital Devices (Linux 4 Media) 4 port (8 tuner) octopus/Duoflex experiences

2012-11-26 Thread Füley István


Hi,

I'm not using such a card, but I use a multituner (4 tuner) VDR setup, 
and I really like this 8 tuner/1slot idea.

I have two major problems with my setup;
1. Using PCI cards I'm limited to a maximum of 5 tuners, and I also need 
to use a PCI gigabit network adapter, so I have 4 tuners. I had bad 
experiences with USB DVB-S2 adapters (random restarts, bad signal 
locking, etc).
2. My 4 tuners are not from the same manufacturer and/or model, so I 
have to use different driver modules for them. But all of my card's 
drivers has some issues. For example one of the cards can't lock on SR 
30k, I have to use 2 in channels.conf. So, if I have a line in 
channels.conf, I'm not 100% sure, that ALL of my tuners will work on 
that channel. This leads to the conclusion, that for multituner setup is 
highly recomended to use ONLY one kind of card with the suitable driver.


In conlcuision I'm also interested, maybe someone can share some 
experiences with Duoflex modules. If they are reliable, having stable 
drivers, it could be an interesting solution for multituner setup.

 If you'r using Ubuntu or yaVDR, there's the linux-media-dkms package with this

 My DVB-C/T card is working here for months with no problems. Second dual tuner

Why build it externally? I was quite certain that the ddbridge drivers
are in mainline for a while now?

Which modules to you select?

ddbridge is upstream with DVB-S2 support, but not the driver for my
C/T-module.

Ah! that explains a lot. I did a quick read through that german site,
but they simply pull the latest media-linux git tree, so that should go
into mainline every cycle or so I guess.

Nevertheless, good to know that DVB-S2 on the ngene is well supported (I
guess ) :)
