Description:
|
|
|
|
DVB Frontend Status Monitor is a plugin that displays some signal information
|
|
parameters of the current tuned channel on OSD. You can zap through all your
|
|
channels and the plugin should be monitoring always the right frontend. The
|
|
transponder and stream information are also available in advanced display modes.
|
|
|
|
The plugin is based on a neat console frontend status monitor application
|
|
called 'femon' by Johannes Stezenbach (see DVB-apps/szap/femon.c for further
|
|
information). The other parts of plugin code are borrowed from the excellent
|
|
'OSD Picture-In-Picture' plugin by Sascha Volkenandt and Andreas Regel. The
|
|
bitrate calculation algorithm originates from the 'dvbstream' application by
|
|
Dave Chapman and the stream information routines from the 'libdvb' library by
|
|
Metzler Brothers.

Installation:
|
|
|
|
cd /put/your/path/here/VDR/PLUGINS/src
|
|
tar -xzf /put/your/path/here/vdr-femon-X.Y.Z.tgz
|
|
ln -s femon-X.Y.Z femon
|
|
cd /put/your/path/here/VDR
|
|
make
|
|
make plugins
|
|
./vdr -P femon
|
|
|
|
Notes:
|
|
|
|
- The plugin supports only those DVB cards with _one_ frontend (do any cards
|
|
with multiple frontends even exist?), because I haven't yet figured howto do
|
|
it without patching the VDR core.
|
|
- Disable the stream analyze to speed up heavy zapping sessions.
|
|
- The signal strength and signal-to-noise ratio values are comparable only
|
|
between the same brand/model frontends. Due to the lack of proper frontend
|
|
specifications those values cannot be calculated into any real units.
|
|
- If the OSD isn't visible, you've configured the OSD height too big or too
|
|
small. Please, try to adjust the variable on the setup page before writing
|
|
any bug reports.
|
|
- There's a shrinked default OSD height for NTSC users: make NTSC_SYSTEM=1
|
|
- The device switching feature is still non-functional.
