Sabrent TV-PCIRC
Introduction
Lots of Chinese supplies making piles of $20 crap.
This page is specific to Sabrent PCI TV Tuner Card 7130/TV-PCIRC01061000290
If you have a different model of Sabrent TV-PCIRC card - well, good luck. They rebadged pretty much anyone's overstock tuner card, so buyer beware.
I just want it to work under Linux!
Use the audio-pass through cable. The remote control doesn't work, but the card tunes NTSC.
modprobe saa7134 card=86 tuner=2 # (maybe tuner=32 for PAL?)
Things on The Card
Encoder/PCI Bridge
Clearly labelled, it's a Philips SAA7130HL.
Tuner
If you peel away (carefully!) the OEM label, the 'tin can' tuner has a sticker that says:
SAMSUNG TCPN9082DC270(T) - - - - - - - - 030527 AIO
The tuner is on i2C bus address 0x60 (which is a pretty standard place for the tuner to be)
Crystals
One 4.000 and one 32.110
The Mystery IR Chip
18-pin package, label removed.
Some sort of IR decoder.
Remote Control
Oddly enough, the remote control keymap is identical to the 'ir_codes_pctv_sedna' keymap.
