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>General tab</dt>
|

The general tab contains information and some per-adapter global
|

configuration.

|
||||
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).
|
||||
Pressing this button will popup a window that allows the user to select
|
||||
a DVB network based on location. The adapter will be populated with
|
||||
multiplexes from these networks and immediately start to scan for services.
|
||||
|
||||
<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.
|
||||

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.
|
||||
Pressing this button will start a process that scans all services on all
|
||||
multiplexes and tries to verify if the service is actually a working
|
||||
TV channel. If so, the channel will be created and mapped to this service.

||||

<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.
|
||||
You can change the displayname for the adapter.
|
||||

|

A service is equivivalent to a TV channel.
|
||||
<p>
|
||||
There are currently no operations that can be performed on a single service.
|
||||
The DVB transmissions contains information about other muxes available
|
||||
on the same network. If this checkbox is enabled, Tvheadend will
|
||||
automatically create new muxes as it receives configuration for them
|
||||
via the DVB networks.
|
||||
|
||||
<dt>Idle scanning
|
||||
<dd>
|
||||
When nothing else happens Tvheadend will continously rotate among all
|
||||
muxes and tune to them to verify that they are still working.
|
||||
If your adapter have problems with lots of tuning, try to disable this.
|
||||
|
||||
<dt>Detailed logging
|
||||
<dd>
|
||||
If this is enabled, Tvheadend will log more information related to
|
||||
this specific adapter. You might wanna enable this if you have some
|
||||
kind of issues in order to better diagnose the problems.

automatic mux discovery enabled the mux will probably come back

quite soon.
