The remote requires Linux 2.6.22

Card features

• PCI
• Video/audio decoder: Philips Semiconductors SAA7133 Video Broadcast Decoder (rev d1)
• RF formats: PAL, DVB-T

The card does not have an AD for sound

Card connectors

The RF inputs are for:

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 DB-T) the connectors can apparently be controlled by software. This is TBD. ???

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.

Module Options

For analog signal (autodetected?):

 saa7134 card=78 tuner=54
