This tab is split in two panes. To the left is a tree which, at root level,
|
|
contains all DVB adapters found by Tvheadend during startup.

<dl>
|
|
<dt>Step by step configuration of DVB
|
|
<dd>
|
|
The DVB configuration is perhaps the most tricky part to configure
|
|
in Tvheadend. Therefore, this section begins with a step-by-step
|
|
guide.
|
|
<ul>
|
|
<li>Click on an adapter in the left pane.
|
|
<li>Click on 'Add mux(es)'. A popup window will appear:
|
|
<br>
|
|
<img src="docresources/muxbylocation.png">
|
|
<br>
|
|
For DVB-T and DVB-C adapters, expand appropriate country.
|
|
DVB-S adapters only have one folder to expand called 'Geosynchronous Orbit'.
|
|
In these folders you find a list of available networks.
|
|
Select the appropriate network and press the 'Add' button.
|
|
|
|
<li>
|
|
Tvheadend will now immediately start to probe each mux for available
|
|
services. Expand the DVB adapter in the tree
|
|
and wait until all muxes has been visisted
|
|
at least once (Status of all multiplexes should change from 'Unknown'
|
|
when a mux has been visited).
|
|
|
|
<li>
|
|
You can now, if you want, verify that the mux scanner has found
|
|
services by expanding the mux nodes.
|
|
|
|
<li>
|
|
Select the adapters again and press 'Probe services'.
|
|
A popup will ask you to confirm this action. Press 'Yes'.
|
|
The Service probe will scan through all services on all muxes on the
|
|
adapter and map them to channels with the corresponding name.
|
|
Progress and result for each service is displayed in the 'System Log'
|
|
at the bottom of the application. Wait until the probing is completed.
|
|
<li>
|
|
Done! You can click over to the 'Channels' configuration tab and
|
|
inspect all working channels.
|
|
|
|
|
|
</ul>
|
|
<dt>DVB Adapters
|
|
<dd>
|
|
A DVB adapter represents a piece of hardware attached to the system.
|
|
DVB receivers with dual tuners will present themself as two adapters
|
|
to the Tvheadend application. Tvheadend support DVB-T, DVB-C and DVB-S
|
|
adapters.
|
|
<p>
|
|
When an adapter is selected, the right pane displays configurable items
|
|
for the adapter. Also available in the right toolbar is a set of operations
|
|
that can be performed on the adapter.
|
|
<p>
|
|
Underneath each adapter in the tree is a list of DVB muxes.
|
|
For more information about muxes, see further down.
|
|
<p>
|
|
There is currently no way of adding a new adapter to Tvheadend when running.
|
|
If a new adapter is plugged into the system Tvheadend needs to be restarted
|
|
in order to detect it.
|
|
<p>
|
|
If Tvheadend has configuration for an adapter and the adapter is missing
|
|
upon startup the configuration will be left untouched in case the adapter
|
|
will be back in the future. There is currently no way to remove configuration
|
|
for a no longer present adapter.
|
|
<p>
|
|
Warning: Unplugging an DVB adapter (USB, etc) during operation (i.e when
|
|
Tvheadend is running) can result in deadlocking the kernel USB subsystem,
|
|
most likely requiring a system restart.
|
|
<p>
|
|
Warning2: Suspending a system is (from a USB driver perspective) equivalent
|
|
to a unplug/insert event. Thus, suspending a system running Tvheadend
|
|
with USB adapters is not recommented at the moment.
|
|
|
|
<dt>DVB Multiplexes
|
|
<dd>
|
|
To put it simply, a DVB multiplex is a digital signal modulated
|
|
at a specific frequency that carries a number of servies (where a
|
|
service could be, but is not limited to, a TV channel).
|
|
<p>
|
|
There are currently no operations that can be performed on a single mux.
|
|
|
|
<dt>DVB Services
|
|
<dd>
|
|
A service is equivivalent to a TV channel.
|
|
<p>
|
|
There are currently no operations that can be performed on a single service.
