How do I 'switch' the driver into T2 mode

[briogoog]

Installed my new tbs6280 card and Mythtv tuned into all the dvb-t channels, but does not see the dvb-t2 ones - google searches suggest the combined dvb-t2 driver is not available for download at the moment, any idea when this be released.
Thanks

I've gone through the build process and got DVB-T working well, I just want to try it with HD channels now. I understand that the TBS6280 can't operate in DVB-T and T2 mode concurrently and that I must swap out the kernel module if I want to use T2. The problem is I can't find where I can choose to build the T2 module.

How do I do it? I'm using mythbuntu 11.04 if it matters.

The DVB-T2 driver for Linux is ready, but we still keep separate drivers for DVB-T only and for DVB-T2 only, which allows
us to test them more efficiently and soon we will merge them in a single driver - you can find the necessary files in the link
http://www.tbsdtv.com/download/TBS6280/linux_dvbt2.rar
which contains two files:

- tbs62x0fe_driver.o.x86
- tbs62x0fe_driver.o.x86_64

before i tell you how exactly to use them i want to tell you how to fast
switch between DVB-T and DVB-T2 driver without restart:

1) it's good that you already built and installed successfully the DVB-T
driver - so make a backup copy of it:

# find /lib -name tbs62x0fe.ko

depends on your kernel that command will return something like:

/lib/modules/2.6.31-14-generic/kernel/drivers/media/dvb/frontends/tbs62x0fe.ko

2) copy the DVB-T only kernel module:

# cp tbs62x0fe.ko /home/luke/tbs62x0fe.ko.dvbt

now you can proceed with building and installing the DVB-T2 driver:

3) all steps are the same as what you did for building and installing
the DVB-T only driver - even you need to use the same driver "110717"
driver package, but after 'untar' the package and before proceed with
the other steps as they are described in any of README files - copy the
two files from the attachment (effectively replace the old files) to
'linux-tbs-drivers/v4l' directory :

# cp tbs62x0fe_driver.o.x86 tbs62x0fe_driver.o.x86_64 linux-tbs-drivers/v4l

4) after you build and install the DVB-T2 driver, you can make backup
copy of the kernel module:

# cp tbs62x0fe.ko /home/luke/tbs62x0fe.ko.dvbt2

so now having backup copies of the kernel modules you can switch very
fast and without reboot between them:

* to load DVB-T2 driver:

# rmmod tbs62x0fe.ko
# rmmod saa716x_tbs_dvb

# cp /home/luke/tbs62x0fe.ko.dvbt2
/lib/modules/2.6.31-14-generic/kernel/drivers/media/dvb/frontends/tbs62x0fe.ko

# modprobe saa716x_tbs_dvb

* to load DVB-T driver:

# rmmod tbs62x0fe.ko
# rmmod saa716x_tbs_dvb

# cp /home/luke/tbs62x0fe.ko.dvbt
/lib/modules/2.6.31-14-generic/kernel/drivers/media/dvb/frontends/tbs62x0fe.ko

# modprobe saa716x_tbs_dvb

i guess you get the idea - just unload the driver, replace the kernel module with the one you want to use and then load the driver.
i hope you will enjoy DVB-T2 HD channels several minutes after you read this:)

Thanks, -now working fine in t2 mode.
Retuned mythtv - found 4 new channels, tried a couple of recordings and it looks very good!

Ok

Daft question :-

When we have the T2 driver loaded, and can tune into the T2 channels, can we still get the orginal T channels?

So for instance I can still record BBC1 (T1) while recording BBC HD (T2) in myth?

When the T2 driver is loaded dvb-t channels are not available via the tbs6280, the post from okbat states that the drivers will be merged so this will be possible in the future,
A second card is needed to do t channels or a manual driver swap.
It does make working mythtv a bit tricky - I need to select the correct 'preferred input' otherwise it all goes wrong.

[manaesh]

Oh - thats a bit of a showstopper then!!!

Okbat - do we know when the combined driver will be made available? This seriously constrains the card.

Personally I would have brought 2 straight away, and I personally know of at least 5 people in the UK who are begging for this type of card. With the combined functionality it will be a killer card.

Please let me / us / mythtv users know when the driver will be released??

Thanks

Hi manaesh,

We are working on Linux driver 3.X and optimistic release date will be within two weeks. But no doubt we will merge DVB-T and DVB-T2 into one driver and you guys don't need to worry

[manaesh]

Brilliant! Look forward to seeing the new driver!

How will it be announced? On this forum?

Many thanks
