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.

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?
Regards,
Michael

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

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.

Well the new FPGA based design uses the nGene driver, so it at the very least is compatible on an API front. It would sound somewhat reasonable that either they re-implemented part of the chip or got some secret IP from micronas ;)
In any case, there is an FPGA on the board that behaves 'like' the nGene :)

I have this strange idea, that I saw the ddbridge reference in the nGene driver. Now that you make me look again, I can't find said reference :)
So I stand very much corrected! The conclusion still holds, the ddbridge + duoflex dvb-s2 should be very well supported!
ddbridge is a completely different driver.

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 29999 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.

I'm using a DuoFlex with a DVB-C/T dual tuner modul. How to build the latest drivers is described here (german only): http://www.vdr-portal.de/board16-video-disk-recorder/board85-hdtv-dvb-s2/113...
If you'r using Ubuntu or yaVDR, there's the linux-media-dkms package with this driver included. My DVB-C/T card is working here for months with no problems. Second dual tuner is ordered... :)

It's not implemented yet. You can however redirect the input of one tuner through the ci, so you can decrypt one transponder.
http://www.vdr-portal.de/board16-video-disk-recorder/board85-hdtv-dvb-s2/p10...
Note: the driver for the C/T dual tuner doesn't create different frontends for C and T, so removing the unused ones and renaming the wanted ones isn't necessary anymore.

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.

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.

CI works fine with the redirect mentioned above. You do not need any copying in userspace in this case.
What could be supported, and this is not possible with any other DVB PCIe card hardware I know of, is that an encrypted stream is sent from memory/hard disk/network to the CI and back for decryption.

I started a plugin to get support of the CI (including MTD) into vdr. But for now no luck so far. I use the CAM handling of the vdr and write the TS packets to the sec device. But reading from it will block and nothing will be decrypted. But I have to learn more about the whole CI/CAM stuff...

Well the interface to decrypt an incoming encrypted stream differs from other available dvb devices with ci. In this case vdr needs to support two diferent ci systems.

If you use the redirect parameter and you take care that the frontend, demux, dvr and ca have the same device numbers, then vdr can decrypt channels on that device without any changes to vdr or in need of any plugins.
But you only will be able to decrypt one transponder. Theoretically the CI is able to decrypt multiple transponders, but for that, vdr has to be extended with some patch and a plugin. I'm afraid there isn't such a plugin at the moment.
Lars.

There is no "solution" for szap/czap. You just set the redirect once and it works like with any other CI hardware.

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.

There are different versions of the STV0900. I doubt that any retail market cards will use the more expensive version which supports 16apsk etc.
Why build it externally? I was quite certain that the ddbridge drivers are in mainline for a while now?
Which modules to you select?

I'm using a DuoFlex with a DVB-C/T dual tuner modul. How to build the latest drivers is described here (german only): http://www.vdr-portal.de/board16-video-disk-recorder/board85-hdtv-dvb-s2/113...
If you'r using Ubuntu or yaVDR, there's the linux-media-dkms package with this driver included. My DVB-C/T card is working here for months with no problems. Second dual tuner is ordered... :)

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 ) :)

I do have a Terratec DVB-T dual (which does dvb-c too on 1 of the dual tuners) which features the drxk demodulator. So I think your card should be quite supported in mainline already.

The newer C/T modules use ST demods. I think the DRX-K is also no longer being produced.

I bought a Terratec dual T PCI-e which features two DRX-K demods. While not the newest card, it's reasonably new and driver support is < 6 months old. I guess there's a huge batch of DRX-K's still being used up?
What demod/tuner is being used on the DVB-S2 bit? Just to know the state of support of the demod/tuner.

I guess but it is not being used on any new Digital Devices cards.

stv0900/stv6110
It uses the drivers stv090x and stv6110x which are also used by several different cards from other manufacturers and are working very well.

Well, those are not my drivers. So, I feel free to praise the work Manu Abraham did on them.

stv0900/stv6110
My card uses stv0367dd, tda18212dd and cxd2099 from the repository I mentioned. No upstream support for now, but I would like to work at that. I will get in contact with the author soon, but since I don't know anything yet about the driver model, I first want to read and understand the code.

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.
