[DVB] Octopus driver status

[DVB] Octopus driver status

[Sébastien RAILLARD (COEXSI)]

Dear all,

I'm looking at the Octopus DVB cards system from Digital Devices for a while
as their system seems to be very interesting 

Here is link with their products:
http://shop.digital-devices.de/epages/62357162.sf/en_GB/?ObjectPath=/Shops/6
2357162/Categories

The good points I have found:

* They support most of the common DVB standards: DVB-C, DVB-T, DVB-S and
DVB-S2
* They are moderately priced
* There is a CAM support with a CI adapter for unscrambling channels
* They are using the now de-facto standard PCI-Express bus
* The new Octopus system is using a LATTICE PCI-Express bridge that seems to
be more future proof than the previous bridge Micronas APB7202A
* They seem to be well engineered ("Designed and manufactured in Germany" as
they say!)

And now the doubts :

* The DVB-C/T frontend driver is specific to this system and is very new, so
as Devin said one week ago, it's maybe not yet production ready
* The way the CAM is supported break all the existing userland DVB
applications (gnutv, mumudvb, vlc, etc.)
* There isn't so much information about the Digital Devices company and
their products roadmap (at least in English)

So, my two very simple questions to the developers who worked on the drivers
(I think Oliver and Ralph did) and know the product:
* How you feel the future about the Octopus driver?
* Do you think a compatibility mode (like module parameter) can be added to
simulate the way the CAM is handled in the other drivers?

I'm ready to buy the different cards and do some testing if it can help.

Best regards,
Sebastien.

The drivers work fine. I am not aware of any problems.

All Digital Devices cards and tuner variants are supported by the driver
http://linuxtv.org/hg/~endriss/media_build_experimental

ddbridge (Lattice bridge):
- Octopus (all variants)
- cineS2 v6
- DuoFlex S2 (stv0900 + stv6110 + lnbp21)
- DuoFlex C/T (Micronas DRXK + NXP TDA18271C2)

ngene bridge:
- cineS2 (v4,v5), Satix S2 Dual
- PCIe bridge, mini PCIe bridge
- DuoFlex S2 (stv0900 + stv6110 + lnbp21)
- DuoFlex C/T (Micronas DRXK + NXP TDA18271C2)

Unfortunately I did not have the time yet to clean up the coding-style.
There are thousands of coding-style issues waiting to be fixed...

Yes, this could be done:
++ The CI could be used with any application.
-- The CI will be attached to one tuner exclusively.

It is not very hard to implement this.
Patches are welcome. ;-)

Ok, thank you for the update.
We will try some Octopus cards.

Hi Oliver,

If it is ok for you, I have here a few devices with DRXK that I'm seeking for
some time to work with. I'll probably have some time this weekend for them,
so I can do the CodingStyle cleanups, if it is ok for you.

Cheers,
Mauro.

Do you have a Terratec Cinergy 2400i? It belongs to the ngene family
but has PLL tuners.
http://linuxtv.org/wiki/index.php/TerraTec_Cinergy_2400i_DVB-T

There are some drivers floating on the net that I have got to work in
Ubuntu 8.04 but the current ngene drivers has moved on a long way and
left it behind.

Si.

I don't have. I have a few Terratec DVB-C devices here with DRXK, using different
bridge drivers. I started looking on them based on a released DRXK driver, but, as
Oliver already had some work on the drxk driver, it is better to merge Oliver series
first and then I start working on adding DRXK support to the other drivers, to avoid
duplicated work at the DRXK drivers.

Just for the record: Ralph did most of the work.
I just contributed some glue stuff.

I'll check with Ralph, whether he has any updates pending.
These should be applied before fixing the coding-style.

If you could wait until next weekend, I could prepare a patch series,
which you could start with. The current repository has some files at
the wrong places, etc.

Sorry, I do not have this device, and I have no plans to work on it.
Terratec did not contribute in any way to the ngene driver. [1]

As always, patches are welcome.

[1] Some time ago I had a look at that driver, and found that it could
    not be added to the kernel, due to an GPL-incompatible proprietary
    license for some files.

Re: [DVB] Octopus driver status

[Rune Evjen]

Dear all,

I am looking into buying the Digital Devices Cine CT V6 (product link:
http://shop.digital-devices.de/epages/62357162.sf/en_GB/?ObjectPath=/Shops/62357162/Products/091203)

Is this card including multiple dvb-c tuners supported by the ddbridge
(Lattice bridge) driver ?

Is the driver available also in git://linuxtv.org/media_build.git or
do I need to use
http://linuxtv.org/hg/~endriss/media_build_experimental ?

Best regards,

Rune Evjen

Cine CT V6 (was: Re: [DVB] Octopus driver status)

[Oliver Endriss]

Hi,

the Cine CT V6 is very new and not yet supported,
but the driver is under development.

When ready, it will be added to media_build_experimental first.
After some testing period it will be submitted to linux-media.

Oliver
