Tvheadend

It sounds like a two tuner version similar to the 4-tuner PCIe card I have.

Hi all I've been away this evening and just got back kow. I've read all your comments and apologies for not supplying certain info. I will do the log check now and report back it's findings here.

It's an outdoor arial and signal was good when I tested it on windows prior to installing Ubuntu.

I used Hauppauge official wintv-10 software and it successfully loaded HD channels e.g. BBC1 HD and ran ok. So I know it's not the Arial.

It just baffles me that Ubuntu and Tvheadend has the correct fw as I'm able to load about 100 channels, but they are all SD and no results from HD appear.

Will post the dmesg shortly

Here is the dmesg. hopefully it answes why i cant get T2 as an option for HD on tvheadend. Many Thanks

Why this is certainly possible, I thought you said 'it works in win'. T2 in the end, is a combination of tuning parameters of reciever (which requires support of course) and mpeg4 support, which is unrelated to tvh.

BTW, if I look at https://hauppauge.com/pages/products/data_dualhd.html#specs it seems to be a:

ATSC HD TV
Clear QAM digital cable TV

tuner?

This is the cable version. I have the arial freeview opttion Rev 316 204209 model version

It would be nice if you could manage to save a version without all the colour control stuff. dmesg just does plain text on my system, so I'm not sure how/why it uses colour on yours, or how to stop it.

One thing I notice is that two days ago Jonas said, quoting from a reply by Hauppauge:

"... https://github.com/LibreELEC/dvb-firmwa ... -d60-01.fw"

But I notice in your dmesg that it says:

"...downloading firmware from file 'dvb-demod-si2168-b40-01.fw'"

So it looks like you may have an older, incorrect version of the firmware.

Ah so you didn’t box it up and return it to the supplier.

Just a few basic questions before I continue to troubleshoot this. If you could answer each question it would help enormously.

What region/country are you based in. This will help determine what T2 muxes you are trying to tune.

Have the T2 muxes been found during the auto scan process. Again this will help determine the next step.

Could you do a screen cap of the tuners that have been found in TVH

Ahh ok so to clarify that you are correct. The version b40 was originally suggested so we used that. Problem still persisted, and upon his further research he doing my device was REV 316, which required a newer firmware (B60).

Both firmwares are currently in the lib/firmware folder. Could Tue two conflict? If so I could take the B40 one out and leave the newer B60 version in?

Hello thanks again. So to answer each question:

1. I'm in the United Kingdom
North east England, our local Arial mast for sour region is Bilsdale North Yorkshire. Which is the muxes option I selected during the initial TVH setup but it could only find 19 channels and the EPG kept repeating the same 19 SD channels. Didn't receive BBC, ITV, Channel 4 and Channel 5

2. The T2 muxes haven't been found during auto scan, just T

3. Can't do that ATM as I'm at work but finish at 5pm so from 6pm onwards I can do that for you and upload it here if that's ok?

How do I do a screen cap? Haha is it just like windows?

Many thanks again for your help. I know it's an odd one.

Daniel, If you're still struggling give me a ping on IRC mpmc [irc.libera.chat / #hts] & I'll give it a try with you over teamviewer if you like.

I’m not in the UK but I do know Bilsdale suffered a catastrophic fire which has caused mayhem with mux changes over the last couple of years.

On top of that on autoscan it appears your dvbt usb device does not auto detect dvbt2 muxes.

Like yourself I’m working too but what I am now going to suggest is that you manually enter the details of one known working mux for your area into TVH and do a manual scan of that mux.

Here’s an extract from a solution similar to your problem.

Workaround:
Autodetect of the HD channels is no longer working (it did before the recent Crystal Palace changes). However, manually adding the MUXs/transports to TVheadend/MythTV etc and specifying that they are QAM256 modulation and 8Mhz bandwidth (rather than leaving them both at Auto) does enable both TVheadend and MythTV to discover the channels on the MUX/transport.

I don't know why auto-detect does not work nor why specifying the modulation and bandwidth manually solves my problem, but am happy to offer my setup as a reproducible testbed for any expert willing to investigate the matter further.

As soon as you get back to your computer post here and I’ll pick it up at some stage.

Finally your system cannot differentiate between different versions of the same firmware so you can only have one version installed at a time. Try this firstly with the older firmware and then the second one if necessary.

Is the version of Ubuntu you are running an actual Ubuntu installation on the hard disk or something like Ubuntu on Windows WSL2 or a VM version.

Why would you want to drag the discussion to TeamViewer. This is an open forum where others will benefit when a solution is finally arrived at. Very strange indeed.

It's worth looking at https://en.wikipedia.org/wiki/Bilsdale_transmitting_station for the story of the fire!

"Transmission equipment for the new mast was switched on in the early hours of Monday 22 May 2023, thereby fully restoring Standard Definition TV signals. HDTV signals, Radio and mobile services are still on the temporary mast, thus not reaching as far."

These issues are never as straightforward as they seem. Look how long it’s taken to ascertain what region the OP is based in.

While no doubt the DVBT2 muxes scan fine in Windows, as you know there are a number of other factors to be taken into consideration when it comes to Linux.

I tried the step by step approach which so far has enabled the OP to install Ubuntu 22.04, install TVH and have his DVBT USB recognised in TVH all of which he stated he couldn’t achieve at the outset.

After my third asking what region he was based in back came the answer I suspected. Not that it has a direct bearing on his issue but when the DVBT USB device is known not to auto detect DVBT2 muxes in auto scan it certainly doesn’t help.

Now that the card is up and running in Ubuntu in TVH my final contribution will be to get the OP to manually input the DVBT2 muxes into TVH and individually scan each mux. Hopefully that will resolve his issue and the solution will be here for everyone to see. If not he can either put it back on Windows or parcel it up and return it as he suggested earlier.

That wasn't my intention at all, it was merely an offer of assistance if wanted by the OP, *using teamviewer just because it's the easiest for most). Honestly, not sure how that is strange. If a solution were to be found by remote assist, it would of course be posted here for the benefit of others too.

Hope that clears up any confusion.

This is most likely the right solution, although I do remember when I used tuners with certain chipsets their drivers were a bit odd and would only work with AUTO values. https://linuxtv.org/wiki/index.php/Hauppauge_WinTV-dualHD#Setting_Transfer_Mode_to_bulk might be something the OP might want to try too.

Basically you press the 'Prt Sc' button and follow the instructions in the popup window. On my keyboard I have to press and hold the 'Fn' button before the 'Prt Sc'. 'Fn' is bottom left, 'Prt Sc' is top right on the 'Insert' key for me.

Yeah that would be great if you can guide me through manually setting up the T2 to receive HD channels.

Yeah I was aware of this it made big news locally. But it's been confirmed by the Bilsdale team that it's all fully commissioned.

Thank you! I'm setting off home now. Before posting here to say I'm ready I'll log on, remove the B60 firmware leaving the original b40. And we can try the manual scan

It's on the internal HDD. It was a fresh install from a bootable USB, on an ex windows 10 desktop. But once this is sorted I'm wanting to plus an external USB HDD to act as the drive were recording go on to.

Read this carefully. It outlines generally the difference between mux settings for DVBT and DVB2. Pay particular attention to the DVBT2 section.

Just for test purposes you can edit one of the muxes that have been found in your previous scan and copy all the settings from the DVBT2 section of this link.

The only difference is you will need to enter a valid frequency for a DVBT2 mux in your area. Make sure you pay particular attention to the format for each field and it matches the fields on this link

https://discourse.osmc.tv/t/howto-retune-tvheadend-dvb-for-uk-freeview-digital-switchover/71793

remove the B60 firmware leaving the original b40

I'd think that the later firmware was more likely to work than the the earlier so I'd start with the 60 myself.

Try scanning BBC DVBT2 first. If no luck try the second DVBT2
