Description

Screenshot

Shows DVB signal information on the OSD.

--------------------------------------------------------------
|## Channel Name ########################## [AR][VF][A/DD][D]|

--------------------------------------------------------------

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)

Options

Option Description
FEMON_NTSC=1 OSD defaults for NTSC system
FEMON_DEBUG=1 Additional debugging information

Problems

  • 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.
