DVB/DTV Extension Board for VIM2 (VTV)

Any way to make a dbt.img to work with LibreElec, like the KIII Pro?

Do you think would be possible to make a box for both, VIM2 and VTV?

Hi Frank, does it decode 4k (UHD) dvb-s2 channels?

yes, 4K is supported.

Well just to inform my “Normal” version and the “ATV” version for the VTV(they can also be used normal VIM2 without the VTV board) are done.
I will be posting it them this weekend


Maybe i have missed something so i am going to ask :slight_smile:
Is there any development on vTV board under Linux and especially with Libreelec?

My experience with vTV/VIM2 MAX and Libreelec is pretty-much the same as the problem explained here

I am really not happy with Android. I have tried all possible variants and available builds on my VIM and VIM2 including with and without vTV board. Actually my fav Android setup is Khadas Android 7.1.2 with Android TV apps sideloaded on and Kodi as a Launcher :))) But comparing to the experience using native Android TV on Shield … Best think using android and Kodi is 1080p/4K videos and suggestions on YouTube :slight_smile: Actually i can’t imagine why somebody will use Android in Khadas having all this good stuff in Linux and Libreelec as STB?! May be because of YouTube streaming in 4K?!

Hi Stefan, I have been able to run libreelec thanks to @kszaq in a vim2 and everything seems to work ok.

However regarding the TV expansion board in libreelec, although I’m seeing it ok in TV adapters tab, I think they are not working, as all the muxes are failing using the sat adapter and I can’t open any channel.

If I use an external sat->Iptv tuner (for example a digibit r1) my vim2 works ok with tvheadend and I can see any channel withoug problems.

This is where we are discussing this: LibreELEC for the VIM2

Libreelec and VIM2 is clear.
About the vTV HAT, there is no working open source linux drivers at the moment and they can’t be compiled as well if you are not a C+ guru having the vendor source :slight_smile: This HAT and all boards on this chipset can be used only with Android. I make an “investigation” and the problem is much more complicated than just to compile some drivers from available source even it is sent by the vendor itself. Don’t push kszaq to help, because he can’t! Even with compiled drivers this board not work (tested) in linux, because they don’t work. The source spinning around is not the correct one! linux drivers are proprietary peace of software used in commercial linux based STBs. No drivers, no TV. I hope that soon, the chipset vendor will open their drivers, otherwise somebody have to write drivers and not to compile them.

@Frank.DTV Can you please share device tree for the DTV Android build so that we can make sure the device tree we provide for LibreELEC is correct? Thank you.

dear kszaq,
please check below dts info that should be useful.

Hi all, the developers in libreelec forum need a dtv board and a vim2 in order to go ahead and see what is happening with this dtv board.
Investigations are now stuck until this happen.


I can send vTV board.
I have bought two and they are completely unusable for me without libreelec support. So contact me with the guys :slight_smile:


Hi Stefan,

Much appreciated that info. @afl1 from libreelec who is now working in the last 9.x libreelec version is the engineer that is stuck now and can’t progress any further without a physical hw.

You can check his last reply here after we were sending all the logs: https://forum.libreelec.tv/thread/10649-khadas-vim2-and-dtv-board/?pageNo=6

I guess the best option is to send him a private message in libreelec or reply him in that post so that he can send you his personal address.

I don’t know if also @kszaq could help us having a physical hw but for sure @afl1 yes.


I already have the DTV board but unfortunately no DVB access to test anything.

I think the vTV vendor @Frank.DTV can also provide free samples for developers

Sorry for my delayed reply.
Yes, I can provide free sample for the developer.

@Gouwa, please help me to provide VTV to the developer who needs it, thanks.


So parking the issues with the modulator. Has anyone got the remote and spidf working in libreelec ?

Hi Frank.
I was asked on LE forum to fix DTV board issue in LibreELEC. I wrote dvb driver for similar board in Mecool K-series boxes based on AVL6862. In Vim2 the dvb driver is succesfuly intialized in DTV board. Tuner is able to lock to frequency but there are no data from demodulator. Basic difference between K-series and DTV is in type of data transfer (parallel vs. serial). Driver for demodulator is hardcoded for parallel transfer and it need some adjustment to enable serial data transfer. It’ll be welcome to have test sample. If you can provide me one, contact me on afl_2001@yahoo.com for post address.

Hi @Frank.DTV , @Gouwa

Please check above post to provide to afl1 a test sample. We need to unlock this libreelec issue.

Thank you.


So, a little more digging on my part reveals that though there is no specific option to select SPIDF on the board, it is enabled along with the SPIDF output on the HDMI port. It is possible that it is enabled on all audio settings by default. On Libreelec AC3 works using pass through and disabling support for AC3 receivers (ie transcoded).
Also I have managed to get a remote control config file for Libreelec partly completed and can share it if anyone needs a copy once I have added a little more polish. Once the basic configuration is set it can be fine tuned with Libreelec’s Keypad editor plugging.


dear @Rashii
OK, we will contact @afl1_1 and provide VTV board to him. thanks
