Sundtek Support Forum

Ich habe zwei Typen des Sundtek MediaTV Pro über einen VDR an DVB-C hängen.
den "alten" Sundtek MediaTV Pro (ID: U120820073259) und den "neuen" MediaTV Pro III (ID: U140724094417)

Bisher hatte ich das Internetmodem an einen Verteiler an der Radiobuchse der Antennensteckdose angesteckt.
Das neue Modem funktioniert aber nur, wenn der Verteiler mit der TV Buchse verbunden ist.

Nur, jetzt gibt es mit dem TV Empfang Probleme, wenn zur gleichen Zeit mit dem Internet gearbeitet wird.

Die Probleme treten vor allem mit dem "neuen" USB Stick auf.
Das Signal habe ich während eines Speedtests von 75Mbps gemessen.
Bei den Tests wurden für beide USB Sticks dieselben Antennen- und USB Anschlüsse verwendet.
Ich habe auch einen zusätzlichen "neuen" USB Stick in Reserve und beim Test mit diesem hat er dieselbe hohe Fehlerrate angezeigt wie der andere "neue".
Ein Sony Fernseher und eine UPC Mediabox zeigen keine Bildstörungen.

Kann es sein, dass der Signalpegel des Rückkanals des Internetmodem den Empfangsteil des "neuen" USB Sticks übersteuert?

Ich habe versucht mir einen Hochpass, der den Rückkanal zu den TV Empfängern hin sperrt, zu beschaffen.
Aber ich hab keinen gefunden.

Gibt es vielleicht eine Einstellung, die diese Empfangsstörungen vermindern könnten?

Mit dem "alten" Stick sieht das Signal so aus (keine sichtbaren Bildstörungen):

aber mit dem "neuen" ist das Signal sehr viel schlechter (sehr starke Bildstörungen):

Hallo,

Ich habe einen Sundtek MediaTV Pro.
DVBT funktioniert ohne Probleme, aber mit Analog-TV habe ich leider keinen Erfolg.

Als Treiber habe ich installiert (2012-09-30?):

/opt/bin/mediaclient --build
Build date: 2012-09-30

Installiert wurde der Treiber auf Ubuntu:

uname -a
Linux ubuntu 3.2.0-31-generic #50-Ubuntu SMP Fri Sep 7 16:17:36 UTC 2012 i686 i686 i386 GNU/Linux

/opt/bin/mediaclient -e

Aber aus /dev/video0 kann ich keine Daten auslesen.

Das Empfangssigal dürfte gut sein.

/opt/bin/mediaclient -d /dev/video0 --readsignal=0

Im medissrv.log File machen mir die zwei "Failed" Zeilen Sorgen, aber ich finde keine Lösung

2012-09-30 14:30:41 [3332] Failed to initialize Transfer (9440)
2012-09-30 14:30:41 [3332] Failed to start analog stream (9644)

Ich habe mit "buildffmpeg.sh" ffmpeg installiert.
Ist das für Analog-TV unbedingt notwendig?
