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 bitrate calculation trick originates from the 'dvbstream'
application by Dave Chapman and the stream information routines are taken from
the 'libdvb' library by Metzler Brothers.
Terminology:
--------------------------------------------------------------
|## Channel Name ########################## [AR][VF][A/DD][D]|
|[=====Signal Strength in % ==============|=================]|
|[=====Signal-to-Noise Ratio in % ========|=================]|
| STR: #0000 (0%) BER: #00000000 Video: 0 Mbit/s |
| SNR: #0000 (0%) UNC: #00000000 Audio: 0 kbit/s |
| [LOCK] [SIGNAL] [CARRIER] [VITERBI] [SYNC] |
--------------------------------------------------------------
STR - Signal strength
SNR - Signal-to-noise ratio
BER - Bit error rate
UNC - Uncorrected blocks
Video - Calculated video bitrate in Mbit/s
Audio - Calculated audio / AC-3 bitrate in kbit/s
LOCK - Everything's working...
SIGNAL - Found something above the noise level
CARRIER - Found a DVB signal
VITERBI - FEC (forward error correction) is stable
SYNC - Found sync bytes
AR - Aspect Ratio: 1:1/4:3/16:9/2.21:1 (optional)
VF - Video format: PAL/NTSC (optional)
A/DD - Audio (0..5) / AC-3 track (optional)
D - Device number: 0..3 (optional)
Controls:
ChanUp/ChanDn - Switch channel up/down
Up/Down - Switch channel up/down
0-9 - Select channel
Ok - Switch between display modes: basic, transponder, stream, AC-3
Green - Select next audio track
Yellow - Select audio channel: stereo, mono left, mono right
Back - Exit plugin
Left/Right - Switch to next/previous device that provides the current channel
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, 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. NTSC users should use a shrinked default OSD height by
compiling the plugin with: make FEMON_NTSC=1
