em2820, Tena TNF-9533 and V4L

[Lee Alkureishi]

Hi all,

Hoping someone on this list can help me with this frustrating problem:

I'm running Mythbuntu 8.04, fully updated. I'm trying to set up a USB TV tuner box, and have made progress but haven't quite got it working. 

The USB box is a Kworld PVR TV 2800 RF. It uses a Empia em2820 chipset, and a Tena TNF-9533-D/IF tuner. Other chips I found under the casing are:
RM-KUB03 04AEAAC6, HEF4052BT, TEA5767, SAA7113H. 

The PCB has the following printed on it: EM2800TV_KW Ver:F

I followed the instructions to install v4l using mercurial, and have got it to the point where dmesg shows that the card is recognised and initialised:
------
dmesg:

----------

(I had to manally tell modprobe to set the card type (18) and tuner type (61), as it does not have an EPROM. Took me forever to figure that out!

The problem arises when I try to do anything with it, though: I've tried a few programs, including mythTV, tvtime and xawtv. I can't find a way to select the TUNER as the input source. The only options are "composite1" or "s-video1". I've got a cheap antenna attached to the antenna connector, and a DTV set-top box attached to the composite input. I can't seem to get any sort of picture to come up on either input, though... Tvtime just gives a black screen, and lets me cycle between composite/s-video. MythTV just dumps me back to the main menu when I try to watch TV. Scanning for channels brings up nothing in Myth setup. 

I tried tvtime-scanner, but it fails:

leeko@leeko-media:~$ tvtime-scanner &
Reading configuration from /etc/tvtime/tvtime.xml
Scanning using TV standard NTSC.
[1] 6918
leeko@leeko-media:~$ 
    No tuner found on input 0.  If you have a tuner, please
    select a different input using --input=<num>.
[1]+  Exit 1                  tvtime-scanner

I tried cycling through input=1 through 4, but they didn't work either (2 through 4 give an error about the card not being able to set its input).

Am I doing something wrong? Surely I should see an option to choose the tuner as an input? As far as I can tell, it looks like it should be working!

The only thing I can think of, is that the tuner may actually have originated outside the USA (i.e. the UK). Would that stop it from working with NTSC channels? And even so, should the composite input not still work? (And why can't I even select the tuner!?).

If I do "ls /dev/video*", the only entry is /dev/video0. 

Thanks in advance for ANY help you can offer. This is driving me nuts! I've been learning as I go along, but I've hit a brick wall now :(

Best regards,

Lee

just for the information about the tuner for now, I made that tuner
entry once for a Kworld/Tevion saa7134 card in the UK.

It also came with a separate tea5767 silicon radio tuner.

Your doubts seem to be correct, the TV tuner won't work for NTSC. Sorry.

Cheers,
Hermann

please don't use that driver, it'S not maintained anymore either.

can you run:

$ apt-get install --reinstall linux-image-`uname -r`-generic

for restoring your kernel?

You should safely be able to compile the latest em28xx driver or grab
debian packages for it (what does uname -r show up?)

$ hg clone http://mcentral.de/hg/~mrec/em28xx-new
$ cd em28xx-new
$ ./build.sh build
$ ./build.sh install

there's also em28xx at mcentral.de available which has alot
subscribers who have em28xx based devices, it only deals about Empia
based devices and appilcations + support for those devices only.

that tuner won't work for NTSC.

We have lots of Kworld stuff also for PAL/SECAM on the saa713x.

They have been early in ATSC support ...

But very likely Lee`s device is from the UK.

My, that is the usual since ever before global silicon tuners did
appear.

It is even far below Philips ME MultiEurope MK3s, 4s, 5s ...

Nothing to check there, old very well known chips are in there baked
together with some "other" discretes including the poorer home brewed
SAW filter.

I have a device with similar chips. All of them are supported. TNF9533-D is PAL, afaik.

> (I had to manally tell modprobe to set the card type (18) and tuner type (61), as it does not have an EPROM. Took me forever to figure that out!

It is possible to add some autodetection for it. Are you using the driver at http://linuxtv.org/hg/v4l-dvb, right? On its dmesg log, it will print some codes that helps to do some tricks for detecting it, based on I2C scan signature.

> The problem arises when I try to do anything with it, though: I've tried a few programs, including mythTV, tvtime and xawtv. I can't find a way to select the TUNER as the input source. The only options are "composite1" or "s-video1".

It seems that you're selecting a different board type.

> I tried cycling through input=1 through 4, but they didn't work either (2 through 4 give an error about the card not being able to set its input).

The proper procedure is to run an usb snoop tool that allows us to know what is the pinup of certain generic entries used to select between tuner/composite/svideo.

> The only thing I can think of, is that the tuner may actually have originated outside the USA (i.e. the UK). Would that stop it from working with NTSC channels? And even so, should the composite input not still work? (And why can't I even select the tuner!?).

The tuner won't work properly in US, since the analog filters inside the tuner is different. Composite should work fine.

Dear Mauro,

Thanks for the response. I've done as Markus suggested (reinstalled my kernel, rebooted, then copy-pasted the lines to hg clone the correct driver folder). I then tried to access the tuner/composite/svideo, but am still not getting anything. 

I tried as you suggested, using usbview as a snoop tool to find out more about my board. Here is the output:

--------------------------------

I'm afraid I really don't know what to do with this now. Can you point me toward instructions on how to use this information to correctly set the card/board/tuner type? I understand the tuner may not work with NTSC signals, but I can work just with the composite! 

For further info, here is the output of dmesg after I followed Markus instructions (It looks the same to me):

I hope this makes sense to you - I just want to be able to watch TV!

Re: em2820, Tena TNF-9533 and V4L

[Lee Alkureishi]

Dear all,

Thank you for the suggestions, but I think this has taken up too much of 
my time already. I wish I had contacted this list sooner, as I spent 
considerable time muddling through based on googling the device.

I followed Douglas's link to build the v4l-dvb sources, but am now 
getting fatal errors when I try to modprobe the em28xx module. I tried 
to follow the ubuntu 8.04-specific fix instructions, but to no avail.

I took the plunge and bought an ATI HDTV wonder, and will receive it in 
a few days. I very much hope that setting this up is considerably easier 
that the USB 2800RF.

I am a bit worried that all the messing around with linux headers, 
sources and the v4l packages may upset the installation of my new card, 
though. If someone could please describe how to get back close to a 
"virgin" state i.e. completely remove v4l, modules and reinstall from 
scratch, I'd be very grateful.

Sorry I can't devote more time to this - I know how important it is to 
the community as a whole to improve legacy hardware support.

Best regards, and thanks again,

Lee
