Teletext is currently available only in MPlayer for v4l and v4l2 drivers.

<span class="application">MPlayer</span> supports regular text, graphics and navigation links.
Unfortunately, colored pages are not fully supported yet - all pages are shown as grayscaled.
Subtitle pages (also known as Closed Captions) are supported, too.
</p><p>
<span class="application">MPlayer</span> starts caching all teletext pages upon
starting to receive TV input, so you do not need to wait until the requested page is loaded.
</p><p>
Note: Using teletext with <tt class="option">-vo xv</tt> causes strange colors.

To enable teletext decoding you must specify the VBI device to get teletext data
from (usually <tt class="filename">/dev/vbi0</tt> for Linux). This can be done by specifying
<tt class="option">tdevice</tt> in your configuration file, like shown below:
</p><pre class="screen">tv=tdevice=/dev/vbi0</pre><p>
</p><p>
You might need to specify the teletext language code for your country.
To list all available country codes use
</p><pre class="screen">tv=tdevice=/dev/vbi0:tlang=<em class="replaceable"><code>-1</code></em></pre><p>
Here is an example for Russian:
</p><pre class="screen">tv=tdevice=/dev/vbi0:tlang=<em class="replaceable"><code>33</code></em></pre><p>
