The TechCom SSD-TV-675 INTERNAL TV TUNER is a cheap tuner card available in India. It uses the PHILIPS 7130 chipset and QSD-MT-S73 RF tuner. The full specification of this card is available at website.

About the driver

My arch Linux system detected the device and loaded the driver saa7134. But the system failed to find the exact card and tuner type. After many trial and error methods I found that the driver option :

modprobe saa7134 card=3 tuner=55

Is able to produce the sound and the option :

modprobe saa7134 card=37 tuner=55

gives me the video.

Changing the kernel source to get the card working

I got help from Hermann pitton of LinuxTv project. I got the card working after making some source code change and a kernel recompilation.

I will explain the steps that I followed to get this card working in my Arch Linux system.

Download the kernel from


Extract it and change the source code of saa7134 card

tar jxvf linux-
cd linux-
find . -iname saa7134-cards.c

That will give the path to the file that you need to edit.

vi ./drivers/media/video/saa7134/saa7134-cards.c

change the vmux value to 3 from 1 in the card SAA7134_BOARD_FLYVIDEO2000 and change the amux to LINE1 and gpio to 0x4000 under the mute section.

[SAA7134_BOARD_FLYVIDEO2000] = {
               /* "TC Wan" <> */
               .name           = "LifeView/Typhoon FlyVIDEO2000",
               .audio_clock    = 0x00200000,
               .tuner_type     = TUNER_LG_PAL_NEW_TAPC,
               .radio_type     = UNSET,
               .tuner_addr     = ADDR_UNSET,
               .radio_addr     = ADDR_UNSET,

               .gpiomask       = 0xe000,
               .inputs         = {{
                       .name = name_tv,
                       .vmux = 1,        <--change to vmux = 3
                       .amux = LINE2,
                       .gpio = 0x0000,
                       .tv   = 1,
                       .name = name_comp1,
                       .vmux = 0,
                       .amux = LINE2,
                       .gpio = 0x4000,
                       .name = name_comp2,
                       .vmux = 3,
                       .amux = LINE2,
                       .gpio = 0x4000,
                       .name = name_svideo,
                       .vmux = 8,
                       .amux = LINE2,
                       .gpio = 0x4000,
               .radio = {
                       .name = name_radio,
                       .amux = LINE2,
                       .gpio = 0x2000,
               .mute = {
                       .name = name_mute,
                       .amux = LINE2,       <----------- change to LINE1
                       .gpio = 0x8000,      <----------- change to 0x4000

After that I have used the Traditional method ( Kernels/Compilation/Traditional ) to recompile the kernel.

After getting the system up with new kernel, you can use the following commands to get the tuner card up.

rmmod saa7134
modprobe saa7134 card=3 tuner=69

You can add the line options saa7134 card=3 tuner=69 to /etc/modprobe.d/saa7134.conf to auto load the module after reboot

# cat /etc/modprobe.d/saa7134.conf 
options saa7134 card=3 tuner=69

Watching TV using tvtime

Install tvtime. The default frequency in tvtime is set to us-cable. You need to scan the channels and add the option --frequencies=custom, if you are in a different country.

$ tvtime-scanner
$ tvtime --frequencies=custom

Recording TV

You can use the following mencoder command to record TV

mencoder tv:// -tv driver=v4l2:input=0:norm=pal:width=640:height=480:device=/dev/video0:\
freq=280.00:alsa:adevice=hw.0,0:audiorate=32000:amode=1:forceaudio:volume=95 buffersize=64\
 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=400:keyint=30 -oac mp3lame\
 -lameopts br=32:cbr:mode=3 -ffourcc divx -o "test.avi"
