![]() ![]() If it didn’t work, check whether you can see the encoded lines at the top of the screen. Hopefully, you’ll get a colourful home page (page 100). Try pressing the teletext button on your remote control. At this point, you should be dropped back to the command prompt. From the configuration menu, select ‘Start VBIT2’ and then exit the utility. Select ‘Options’ and then both items to make sure you keep up to date and start the service on boot. ![]() When you return to the main menu, a few new items will have appeared. If you get an error at this point, try another option and then select ‘Update services’. Some are community projects others are archives of commercial services such as Ceefax, the BBC teletext service. Out-of-the-box, VBIT2 offers a selection of teletext services. Tap ENTER to select and then review the choices. That’s because VBIT2 cannot run until it’s got some content to work with. You should now see a rather lonely ‘Install service’ menu item. After downloading everything it needs, it will go straight into the configuration menu. This will also install a configuration utility, similar to raspi-config, that will help you get set up quickly and easily. To install VBIT2, raspi‑teletext, and all its dependencies, run this from the command line: curl Thankfully, the community has made the installation of this collection of software a piece of digital cake. The software that generates the teletext signal for us is called VBIT2 by Peter Kwan, with the help of raspi-teletext by Alistair Buxton. Double-check Display Options > Underscan is set to ‘No’. If you have configured overscan compensation in raspi-config then it will not be able to do so. Also, for the teletext software to work, the TV has to be able to ‘see’ the encoded data at the top of the screen. If not, run sudo raspi-config and enable composite output in Display Options > Composite. Disconnect any HDMI cable you have been using, and make sure you have a working display. Make sure your composite output is working from boot. Now save and exit ( CTRL+ X followed by Y). Near the bottom of the file, look for a line that reads: dtoverlay=vc4-kms-v3dĬomment it out so it looks like this: #dtoverlay=vc4-kms-v3d Open the main configuration file as follows: sudo nano /boot/config.txt If you are using Bullseye, the latest major release of Raspberry Pi OS, then Raspberry Pi requires a little configuration change. Once your OS is installed, open a command line, or SSH into your Raspberry Pi and before continuing, make sure everything is up-to-date with sudo apt -y update & sudo apt -y upgrade. You can install either full Raspberry Pi OS or the Lite version, which is preferable if you’re going to be displaying teletext all the time. This is done at the frame buffer level, which means a graphical user interface, such as Raspberry Pi Desktop, is not required. The software we are going to use creates this encoded information, which the TV will detect as a teletext signal. Teletext works by adding encoded data to the top few lines of the PAL video signal, which is why we cannot use HDMI for this project. Older CRT televisions will also give a truly retro feel to the project. You can normally see from the remote control whether it has the capability. These are hard to find new but are plentiful second hand. You’ll also need a TV with a built-in teletext decoder. That said, this tutorial will work with any Raspberry Pi with a composite video signal out. The computing requirement of the project is quite low, so a Zero-class device is perfect and cheap too. We’re basing this project on our Raspberry Pi Zero 2 W build from issue 113 of The MagPi to which we added composite video output last month. Teletext is back! Here, we’ll show you how to get a teletext service running and even create your own pages. Did you think teletext was gone forever? Well, not only have a small group of dedicated archivists been saving and transcribing old teletext signals, but they have produced Raspberry Pi software that can generate the signals required to deliver those pages to your TV. What was wrong with the beautiful teletext pages that came into our homes in the 1980s? The latest news, pop gossip, holiday bargains, and of course Digitiser. Feeling retro? In the latest issue of The MagPi magazine, PJ Evans shows you how to turn any Raspberry Pi into a teletext broadcast service, make your own pages, and even generate content from the web. ![]()
