ASUS My Cinema-P7131 Hybrid
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.
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, 7Z – 728 KiB, TBZ – 1.80 MiB, or ZIP – 2.08 MiB, contains 114 files.
- DVB firmwares v1 (deprecated) 7Z – 454 KiB, TBZ – 1.32 MiB, or ZIP – 1.53 MiB, 36 files.
- 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=112 tuner=54
(it used to say card=78, but that's the ASUS P7131-dual, not the -hybrid. I'm not yet sure if tuner=54 works -- REW)
module saa7134 was loaded automatically, but in addition command "modprobe saa7134_dvb" was required. Only after this the directory /dev/dvb appeared.

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
