Revision as of 03:07, 1 July 2009
A PCI DVB-T card from ASUS.
The analog part of this card works out of the box.
Not sure if it is exactly the same card as the ASUS P7131 Dual.
- note: ASUSTek P7131 Dual, and ASUSTek P7131 Hybrid are not identical. In linux kernel modules 2.6.28 'Dual' is detected as card 78, 'Hybrid' is detected as card 112. Association of FM Radio and RF signals differs slightly.
Overview/Features
- PCI
- RF formats: PAL, DVB-T
The card does not have an AD for sound.
Card connectors
- RF signal: Two IEC connectors
- Video Input: S-Video mini-DIN
- IR-Remote: 2.5mm jack
- Audio output: Card internal
The RF inputs are for:
- PAL TV RF signal
- DVB-T RF signal
- FM radio RF signal
The original documentation says:
Upper IEC connector is marked "RF/FM-IN" and is for FM radio and DVB-T
Lower IEC connector is marked "CATV-IN" and is for PAL TV
The FM radio is fixed to the upper connector, but for TV (PAL and DVB-T) the connectors can apparently be controlled by software. This is TBD. ???
- note: In several cases users had to connect their antenna to the analog plug for dvb-t!
- note: Signal association can change after booting into Windows and using bundled Win32 software to control card. Best solution is to split antenna signal and attach to both connectors.
Components Used
- TV tuner: tda8290+75
- Analog demodulator: ??
- FM radio chip: ??
- tda10046 demodulator
- Video/audio decoder: Philips Semiconductors SAA7133 Video Broadcast Decoder (rev d1)

Making it Work
Firmware
This card requires a firmware file (dvb-fe-tda10046.fw) for the DVB-T demodulator. This file can be obtained two different ways:
- download a package containing this and many other firmwares…:
DVB firmwares v2, 725KiB, contains 111 files
DVB firmwares v1, 1,52MiB, bigger because of worse compression, contains 36 files. Outdated.
- note: If you can provide proper hosting, you're welcome to re-host the file and edit this page.
- using the get_dvb_firmware perl script, included with kernel sources, which will download the Windows driver file and rip the firmware out of it:
cd /[kernel source directory]/Documentation/dvb/
perl get_dvb_firmware tda10046
Kernel source directory will usually be /usr/src/linux/. Whatever method you choose, once the download is complete, place a copy of the firmware file in your /lib/firmware directory. (This directory may differ with some distros i.e.depending on your hotplug version it could be /usr/lib/hotplug/firmware/ ; consult your distro's documentation for the appropriate location):
sudo cp dvb-fe-tda10046.fw /lib/firmware
(replace /lib/firmware with /usr/lib/hotplug/firmware/ if required)
Bugs
This is not tested yet:
Get firmware, old option
In /usr/src/linux/drivers/media/video/saa7134/saa7134-dvb.c, line 873, struct tda1004x_config philips_tiger_config change the entry
.request_firmware = NULL
to
.request_firmware = philips_tu1216_request_firmware
Run /usr/src/linux/Documentation/dvb/get_dvb_firmware and copy the dvb-fe-tda10046.fw to /lib/firmware
modprobe saa7134 card=78 gpio_tracking=1
See http://www.spinics.net/lists/vfl/msg27672.html
Get firmware, new option
The Mercurial version "emerge v4l-dvb-hg" gives the card a proper card number of 112. The card can then be brought up with
modprobe saa7134 card=112 tuner=54 gpio_tracking=1 i2c_scan=1
You may also need to
modprobe saa7134-dvb modprobe saa7134-alsa
This works now but may not continue to do so.
Drivers
Module Options: For analog signal (autodetected?):
saa7134 card=78 tuner=54
module saa7134 was loaded automatically, but in addition command "modprobe saa7134_dvb" was required. Only after this the directory /dev/dvb appeared.
Sample kernel output
From Gentoo linux kernel 2.6.28-r2 (as second PCI card):

Remote control support
An IR remote control is supplied. There is a sensor cable that must be plugged into the card.
The remote requires Linux 2.6.22
