Together with the Linux Kernel, the Digital TV developers support some simple utilities which are mainly intended for testing and to demonstrate how the DVB API works. This is called DVB v5 tools and are grouped together with the ``v4l-utils`` git repository: https://git.linuxtv.org/v4l-utils.git/ You can find more information at the LinuxTV wiki: https://www.linuxtv.org/wiki/index.php/DVBv5_Tools The first step is to get a list of services that are transmitted. This is done by using several existing tools. You can use for example the ``dvbv5-scan`` tool. You can find more information about it at: https://www.linuxtv.org/wiki/index.php/Dvbv5-scan There are some other applications like ``w_scan`` [#]_ that do a blind scan, trying hard to find all possible channels, but those consumes a large amount of time to run. .. [#] https://www.linuxtv.org/wiki/index.php/W_scan Also, some applications like ``kaffeine`` have their own code to scan for services. So, you don't need to use an external application to obtain such list. Most of such tools need a file containing a list of channel transponders available on your area. So, LinuxTV developers maintain tables of Digital TV channel transponders, receiving patches from the community to keep them updated. This list is hosted at: https://git.linuxtv.org/dtv-scan-tables.git And packaged on several distributions. Kaffeine has some blind scan support for some terrestrial standards. It also relies on DTV scan tables, although it contains a copy of it internally (and, if requested by the user, it will download newer versions of it). If you are lucky you can just use one of the supplied channel transponders. If not, you may need to seek for such info at the Internet and create a new file. There are several sites with contains physical channel lists. For cable and satellite, usually knowing how to tune into a single channel is enough for the scanning tool to identify the other channels. On some places, this could also work for terrestrial transmissions. Once you have a transponders list, you need to generate a services list with a tool like ``dvbv5-scan``. Almost all modern Digital TV cards don't have built-in hardware MPEG-decoders. So, it is up to the application to get a MPEG-TS stream provided by the board, split it into audio, video and other data and decode. h](h)}(hHow can I watch TV?h]hHow can I watch TV?}(hjhhhNhNubah}(h]h ]h"]h$]h&]uh1hhhhK hjubj)}(hXA Together with the Linux Kernel, the Digital TV developers support some simple utilities which are mainly intended for testing and to demonstrate how the DVB API works.

On my personal experience, usually TV cards need stronger signals than TV sets, and are more sensitive to noise. So, perhaps you just need a better antenna or cabling.
