REMOTE CONTROLLER with bt878 kozumi KTV-01C


Hello!

I recently bought the kozumi KTV-01C that is a very cheap pci tv card.

When I booted linux (fc 6) it autoloaded the modules bttv, and bt878.

But with tvtime, zapping, xawtv, or kdetv I was getting no signal, so I looked up in internet and I found how to configure it correctly, I have to rmmod the modules that are loaded by default and modprobe them with correct parameters.

modprobe bttv radio=1 pll=1 tuner=38 card=51 (with card=70 it works exactly the same)

modprobe bt878 verbose=1

This way I can see tv, some channels don't work so good, but w/e.

The radio works perfectly with gnomeradio, but, the thing I just have left to configure it great is to make the remote controller to work.

I've been reading about lirc, but no, I don't know how to configure this. Is this the app I have to use?

All works perfect in Win Xp, but it's a shame I have to use it every time I want to watch tv.

Can anybody help?

You need to find out more about the controller. I guess it uses a USB dongle of some sort? If so you can either look for it in the output of 'cat /proc/bus/usb/devices' or, just after plugging it in, run the 'dmesg' command and check the last dozen or so lines of output for information about the device.

I think LIRC tries to cover as many different remotes as possible, but there are many different types.

It is a pci card, not usb.

What should I do?

So the IR pickup is on the TV card itself? I never used one of those. You could take a look at the instructions here:

http://linux.bytesex.org/v4l2/faq.html#ir

Only a starting point, but maybe there is more in the LIRC documentation.

The IR it is in the card itself, let me show you, I arranged something for showing you:

http://www.mauriciofernandez.com.ar/imagenes/tvcard.png

I loaded the module (as it says in the page you told me to look in) "ir-kbd-i2c" and it loads fine.
But, the remote control doesn't work, it is like I didn't do anything, this module loading didn't help at all.

I'm very upset with this! How is it possible that in windows it works as good as it cans and in my fc6 it is so hard to configure?

Help me please

Windows forces all the companies to provide drivers and setup. In linux the community(you and I) have to supply those drivers and setup.

I wish there was drivers for this in linux too!

I don't think windows pushes everyone to make drivers for it, I think the hardware manufacturers make also the drivers for windows because they know that almost everybody will use the hardware they make under windows, and not in linux.

I'm not so expert (in fact, not at all) to know how to make a driver, or to configure properly a complicated software, I just like to use free software that's why I'm trying with linux.

Someone can help about the remote control?

Thank you very much

thank you lazlow:

I checked http://tvtime.sourceforge.net/lirc.html but I think this is too advanced for my problem.

First I think I have to find a module that fits correctly to the card, I don't know which, but I know that it exists out there.

I think I have to configure it well first ( I don't know , so tell me if I'm wrong!) and then yes, configure lirc.

Or do I have to configure lirc, so it recognizes my ir-remote-control-receiver-attached-to-the-card first?

please help

Add the following line to the Modules section of /etc/X11/xorg.conf. The v4l line is require only for bttv or bt878 cards.

Load "v4l"

If the card has other video inputs, try them. Not all documentation on the internet are correct when providing the tuner information. Unfortunately you will have go through one by one of the tuner number until it can receive channels correctly. Look up tuner.CARDLIST in the kernel source Documentation directory.

lirc is an programmable infrared remote control interface. It has a daemon program that can read the remote control signals or programs like mplayer can be controlled directly from it. lirc's utility irexec is the daemon that can control programs. lirc can also control the mouse.

Excuse me, I'm a newbie. I added Load "v4l" to /etc/X11/xorg.conf at the last line, and the result was a complete crash, so I fucked up.
Thanks to God that I could copy the original from xorg.conf.back, because if not, I don't know how would I start x with the nvidia drivers again.

How can I do this you told me, can you explain me how? so I don't make a catastrophe again :-P

Thanks

Getting back to the link at http://linux.bytesex.org/v4l2/faq.html, is there any mention of the device in the output of 'cat /proc/bus/input/devices'? Typically this just shows the keyboard and mouse.

If it is there you need to somehow get it to talk to the TV viewing application. As the FAQ says this may involve some configuration of X-windows. Maybe Electro's first suggestion is relevant here.

Alternatively, as the last section of FAQ describes, you can try to use LIRC instead.

I confess I do not know how this type of remote should work. I assume it would have to pass signals to the operating system through the PCI bus, rather than communicating with the tuner on the card directly.
