Hallo zusammen,
seit kurzem plagen mich Artefakte im Bild. Sie treten immer dann auf, wenn mehr als zwei Tuner in meinem VDR
genutzt werden. Als Hardware ist eine DD Cine S2 V6 (auch schon mit einer V6.5 getestet), ein Duoflex S2 im
VDR verbaut, Treiber ist dddvb 0.9.19 aus yaVDR 0.5 testing. Multiswitch ist ein JULTEC JRM 0508T, LNB ist das
Inverto IDLB-QUTL 40, Kabellängen ca. 20m.
Testweise habe ich gerade mal 4 Instanzen von szap bemüht und diese Ausgaben bekommen:
1. Tuner:
root@htpc:~# szap -H -a 0 -r -c astra_channels.conf "KiKA HD"
reading channels from file 'astra_channels.conf'
zapping to 1144 'KiKA HD':
sat 0, frequency = 11347 MHz V, symbolrate 22000000, vpid = 0x19d2, apid = 0x19dc sid = 0x2b98
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
status 1f | signal 71% | snr 82% | ber 0 | unc 0 | FE_HAS_LOCK
status 1f | signal 71% | snr 82% | ber 0 | unc 0 | FE_HAS_LOCK
2. Tuner:
root@htpc:~# szap -H -a 1 -r -c astra_channels.conf "TELE 5 HD"
reading channels from file 'astra_channels.conf'
zapping to 574 'TELE 5 HD':
sat 0, frequency = 12574 MHz H, symbolrate 22000000, vpid = 0x01ff, apid = 0x1fff sid = 0x1519
using '/dev/dvb/adapter1/frontend0' and '/dev/dvb/adapter1/demux0'
status 00 | signal 66% | snr 80% | ber 0 | unc 172 |
status 1f | signal 68% | snr 80% | ber 0 | unc 0 | FE_HAS_LOCK
3. Tuner:
root@htpc:~# szap -H -a 2 -r -c astra_channels.conf "ProSieben HD"
reading channels from file 'astra_channels.conf'
zapping to 1222 'ProSieben HD':
sat 0, frequency = 11464 MHz H, symbolrate 22000000, vpid = 0x01ff, apid = 0x1fff sid = 0xef75
using '/dev/dvb/adapter2/frontend0' and '/dev/dvb/adapter2/demux0'
status 00 | signal 67% | snr 81% | ber 0 | unc 0 |

4. Tuner:

Schalte ich Tuner 4 hinzu, ist es teilweise ganz aus.

Zuerst hatte ich die Cine S2 im Verdacht und sie mit einer V6.5 getauscht, aber auch hier das gleiche Verhalten.
Woran kann es noch hängen: Multischalter, LNB, Spannungsversorgung des LNB (Strom ist an der Cine und
Duoflex angeschlossen), Kabel marode?
Bin für jeden Tip dankbar.
Cheers,
Ole
