I have setup this card with gentoo 2008. In some others distributions like Ubuntu or Fedora, I’m sure it should be easier.
The card that I’m writing about is:
|
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) |
It works with module 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
after that we edit /etc/modprobe.conf or /etc/modprobe.d/bttv and we add the following lines:
|
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 |
Now we can try the card with:
|
modprobe bttv modprobe tuner |
We can check if they loaded successfully:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

Install tvtime:
You should set it to the norm of you country, I set it to PAL-Nc:
|
$ tvtime-configure -n PAL-Nc $ tvtime-scanner |
And if everything went well, we should see something like this:
|
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 |
Last, but not least, we have to add to /etc/modules.autoload.d/kernel-2.6 tuner:
|
echo "tuner" ]] /etc/modules.autoload.d/kernel-2.6 |
Remote Control
In order to setup the remote control you have to edit a few lines in the kernel module. We are going to edit $source/drivers/media/common/ir-keymaps.c:
Anf where it says IR_KEYTAB_TYPE we remove all the keys and we leave it like this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37

IR_KEYTAB_TYPE ir_codes_pixelview[IR_KEYTAB_SIZE] = { [ 0x00 ] = KEY_0, [ 0x01 ] = KEY_1, [ 0x02 ] = KEY_2, [ 0x03 ] = KEY_3, [ 0x04 ] = KEY_4, [ 0x05 ] = KEY_5, [ 0x06 ] = KEY_6, [ 0x07 ] = KEY_7, [ 0x08 ] = KEY_8, [ 0x09 ] = KEY_9, [ 0x1c ] = KEY_RADIO, /* FM Radio */ [ 0x0a ] = KEY_BACKSPACE, /* Recall */ [ 0x12 ] = KEY_ESC, /* POWER */ [ 0x18 ] = KEY_LEFT, /* VOL- */ [ 0x0c ] = KEY_RIGHT, /* VOL+ */ [ 0x16 ] = KEY_ENTER, /* OK */ [ 0x17 ] = KEY_D, /* Plus */ [ 0x10 ] = KEY_F, /* Mode */ [ 0x0b ] = KEY_UP, /* CH+ */ [ 0x0b ] = KEY_UP, /* CH+ */ [ 0x15 ] = KEY_DOWN, /* CH- */ [ 0x14 ] = KEY_H, /* OSD */ [ 0x13 ] = KEY_MUTE, /* Mute */ [ 0x0f ] = KEY_BACKSPACE, /* Prev */ [ 0x0e ] = KEY_STOP, /* Stop */ [ 0x1f ] = KEY_PLAY, /* Play */ [ 0x1e ] = KEY_PAUSE, /* Pause */ [ 0x1d ] = KEY_RECORD, /* Record */ [ 0x1a ] = KEY_F7, /* Next */ [ 0x0f ] = KEY_A, /* */ [ 0x1b ] = KEY_F5, /* Time Shift */ [ 0x19 ] = KEY_S, /* Snapshot */ [ 0x0f ] = KEY_F6, /* Prev */ [ 0x0d ] = KEY_E, /* Stereo */ [ 0x11 ] = KEY_I /* Source */ }; |
EXPORT_SYMBOL_GPL(ir_codes_pixelview);
Then, in the kernel source directory, we run:
make && make modules_install y listo.
