Hello,

 

just to be clear I have no idea how teletext is technically  implemented or what is needed for it to work.

 

When I click on the teletext button on my remote , it sometimes works and often not.

 

I see that the service is provided by www.tuxtxt.net. 

 

If I am right in old days before I used an enigma box  there was no internet service like tuxtxt involved. The responses on teletext appeared to be quicker and more stable.

Nowadays I often have for example RTL teletext when watching ARD.

 

Is there a way to not use tuxtext but tho use the teletext provided with the television signal (if there is such a thing)

 

I apologise if this is a silly question!

 

Many Greetings

No, the software is called tuxtxt.

 

Teletext is something that is broadcasted by the provider, on a seperate PID. If you see strange things, chances are you have caching enabled, and the current channel doesn't broadcast a TXT PID.

 

And I can't reproduce what you are experiencing, If I zap to either ARD or RTL, and immediatly press the TXT button, I get the start page instantly, no delay (and not the wrong page).

I dont have problems with teletext on Das Erste and RTL either. All seems to work just fine.

However German channels have something else that is called DigitalText which is a deviation of teletext but broadcasted through HBBTV (Web based).

That can have problems due to the poor handling of HBBTV in latest version of firmwares....

ok,

on menu  I have System/Customize/Enable teletext caching = false.

 

What happens on my vu+ is the following.

 

If I reboot the box and the first channel is ARD and then I click on the teletext button: ARD correctly shows up. And is very quick.

If I switch to RTL  the "searching for teletext dialog screen appears. Then after a few seconds another screen appears where it shows: Teletext selection : Das Erste HD"

 

If I reboot the box and the first channel is RTL  and then I click on the teletext button: RTL correctly shows up on teletext.

What could be wrong on my system?

What is happening in my opinion is that it doesnt find the txt pid for the second channel and try to search for other txt pids available on the whole transponder. So it find the RTL HD or Das Erste HD as a possible options.

Something must be wrong with your perception imho.

I just tried that on several channels on 19.2E (Das Erste, RTL, RTL2, RTL HD, Sat1, Pro7) and have no issues at all with displaying the correct Teletext for the channel.

 

Maybe you can share with what version of OpenPli you testing it and maybe you can try the latest nightly and try with it.

I am using the latest openpli-9.0 release build date 2023-12-03

Please find attached a debug log:

 

I first switched to RTL where teletext worked and then to ZDF where it failed.

Not sure If you see something on the logs?

 

maybe the

 

[ActionMap] Keymap 'InfobarTeletextActions' -> Action = 'startTeletext'.

[eThread] old thread joined 0

TuxTxt <open /dev/dbox/lcd0>: No such file or directory

looks wrong?

You have FCC on, perhaps tuxtxt isn't compatible with it, and gets confused with multiple PID's pre-tuned?

[elmann]

Ha I found the cause!!!

But I am sad too, Its related to  Fast Channel Change. If I disable it teletext works like a charm.

 

But FCC is my number one feature. I cannot live without it )))-:

 

So I guess I have to not use teletext ..... 

[elmann]

Ah Sorry Wanwizard I saw your post too late. You are absolute right its FCC

[WanWizard]

I've passed the issue on to the developers.
