Me llevo un par de días asi que lo comparto con ustedes, ya que le puede beneficiar a alguien mas En este caso yo lo configure con gentoo 2008, quizás haya distribuciones, en las que les sea aun mas fácil configurar este dispositivo. La placa en cuestión es:

04:09.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) 04:09.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11) |
Que funciona con el modulo bt878
|
|
Device Drivers ---] [M] Video For Linux [*] Enable Video For Linux API 1 compatible Layer [*] Video capture adapters ---] [M] BT848 Video For Linux [*] DVB/ATSC Support for bt878 based TV cards make && make modules_install |
Editamos /etc/modprobe.conf o /etc/modprobe.d/bttv y agregamos los datos del modulo:
|
|
alias char-major-81 videodev alias char-major-81-0 bttv options bttv pll=1 card=120 radio=1 tuner=38 remote=1 bttv_verbose=1 gbuffers=4 options ir_common debug=1 |
Ahora podemos probar con:
|
|
modprobe bttv modprobe tuner |
Podemos verificar que los modulos esten arriba:

Instalamos tvtime:
configuramos la norma PAl-Nc para nuestro usuario:
|
|
$ tvtime-configure -n PAL-Nc $ tvtime-scanner |
Y si todo salio bien, deberíamos ver una salida como esta:
|
|
Scanning using TV standard PAL-NC. Scanning from 44.00 MHz to 958.00 MHz. Found a channel at 54.50 MHz (52.50 - 56.25 MHz), adding to channel list. Found a channel at 66.50 MHz (64.25 - 68.50 MHz), adding to channel list. Checking 79.00 MHz: - No signal |
Por ultimo agregamos a /etc/modules.autoload.d/kernel-2.6 tuner:
|
|
echo "tuner" ]] /etc/modules.autoload.d/kernel-2.6 |
Y ya esta, para configurar el control remoto, hay que[…]
