DVB-T ontvanger testen

Controle device nodes

Kijk eerst of er een DVB ontvanger aanwezig is. Onder /dev hoort de map dvb aanwezig te zijn:

$ ls -l /dev/dvb/adapter0/*
crw-rw---- 1 root video 212, 4 May 15 10:21 /dev/dvb/adapter0/demux0
crw-rw---- 1 root video 212, 5 May 15 10:21 /dev/dvb/adapter0/dvr0
crw-rw---- 1 root video 212, 3 May 15 10:21 /dev/dvb/adapter0/frontend0
crw-rw---- 1 root video 212, 7 May 15 10:21 /dev/dvb/adapter0/net0

DVB-T ontvanger testen met vlc

Gebruik nu vlc om de ontvanger te testen:

# pacman -S vlc
$vlc
Media -> Open Capture device,
Capture mode : DVB
Adapter card to tune: /dev/dvb/adapter0
DVB type: DVB-T
Transponder / multiplex frequency: 722000
Bandwidth: auto => play

Nu zal vlc alle kanalen scannnen, en na ongeveer 10 minuten het eerste beeld en/of geluid geven.

Als de permisies van /dev/dvb/adapter0 verkeerd staan zal vlc de volgende melding geven:

dvb access error: FrontEndOpen: opening device failed (Permission denied)
main input error: open of `dvb://frequency=0000' failed: (null)

Voeg dan jezelf toe aan de groep "video":

# usermod -a -G video yourusername

DVB-T ontvanger testen met tzap en mplayer

Installeer mplayer en tzap (onderdeel van linuxtv-dvb-apps)

# pacman -S linuxtv-dvb-apps mplayer

Scan nu naar de digitenne kanalen in nederland:

$ mkdir ~/.tzap
$ scan /usr/share/dvb/dvb-t/nl-All -o zap | tee ~/.tzap/channels.conf
scanning /usr/share/dvb/dvb-t/nl-All

Dit levert het bestand ~/.tzap/channels.conf op. Hierin is te zien dat Nederland 1,2 en 3 op 474 MHz zitten, en dat Discovery channel op 498MHz zit. De frekwenties zijn afhankelijk van uw locatie.

Nederland 1:474000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_1_2:FEC_1_2:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_4:HIERARCHY_NONE:7011:7012:1101

Nu kan de tuner afgestemd worden op bijvoorbeeld Nederland 1

$ tzap -a 0 -r 'Nederland 1'
