PixelView PlayTV Pro PV-BT878P+9X

Using “Designed for …” hardware with Linux was always a pain. Vendor support suggests to “use software from CD”, and check if card is properly installed “by clicking on My Computer, and then …”. And then I explained that I’m running Linux. I was told that Linux is not supported and card is not prepared to work with it.

I have tested some bttv “card=” parameter options and I realized that none of them works properly. With most of them I was unable to tune to any TV station, with other there was no sound and radio does not work with any of them.

I have finally installed this card into borrowed Windows box and use BtSpy to investigate Windows drivers. Card in Windows was correctly detected and system requested drivers from CD. After installing them and rebooting proprietary software was able to scan television channels and radio stations. I run BtSpy and followed each step it proposed. Here is its report:

Bttv driver

After reading very helpful bttv documentation I find proper configuration.

Just create /etc/modprobe.d/bttv with this contents:

options bttv card=70 tuner=38 radio=1 gpiomask=0x3F audiomux=33,32,35,35,40
# address of tuner should be detected automatically,
# if it fails uncomment next line
# options tuner addr=0x61

GPIO mask and audiomux values comes from report (they are converted from hex to decimal). My card have no NICAM decoder and cannot work with card=72. Using addr=0x61 option is need only with older bttv driver and disables radio.

Television

Now, we are ready to search for TV stations. Install scantv package and run:

$ scantv -C /dev/vbi0

When it find station you will see message similar to:

E5   (175.25 MHz): TVP Katowice
[TVP Katowice]
channel = E5

E6   (182.25 MHz): ???
[unknown (E6)]
channel = E6

Watch TV with TvTime or XawTV (both available as Debian packages).

Teletext

Install AleVT set channel with XawTV or TvTime and run AleVT with command:

$ alevt -finetune auto -charset latin-2 -vbi /dev/vbi0

Radio

Install radio package and search for radio stations running:

radio -c /dev/radio0 -i

When it find station you will see:

[Stations]
baseline at 6.10
Station  0:  89.15 MHz - 7.00
89150000=scan-0
Station  1:  90.05 MHz - 7.00
90050000=scan-1
Station  2:  90.60 MHz - 7.00
