TBS6925 DVB-S2 PCIe Cards is a professional satellite PC TV card, which supports CCM, VCM, ACM mode
and 16 APSK & 32APSK Demodulator, It is the only PC card with flexible DVB S2 MIS transmission technology. It captures up to 190 Mbit/s channel bit rate. Linux driver supports all kernels up to 2.6.38.
Overview/Features
- 1X PCI express slot
- DVB S2 MIS Reception with VCM/ACM
- Multiple Transport Stream Receiving
- Generic Stream capture
- Up to 190 Mbit/s channel bit rate capture
- symbol rates from 200Ksps to 45Msps
- The card has two F connectors, one Input and one Loop connector.
Components Used
- STB6100 (Tuner)
- STV0900AAC (Demod)
- SAA7160

Identification
$lspci -vvvnn 02:00.0 Multimedia controller: Philips Semiconductors SAA7160 (rev 03) Subsystem: Device 6925:0001 Flags: bus master, fast devsel, latency 0, IRQ 18 Memory at fdf00000 (64-bit, non-prefetchable) [size=1M] Capabilities: <access denied> Kernel driver in use: SAA716x TBS Kernel modules: saa716x_tbs-dvb
Making it work
I.1 extract linux-tbs-drivers.tar.bz2 archive:
- tar xjvf linux-tbs-drivers.tar.bz2
I.2 go to driver package directory:
- cd linux-tbs-drivers
I.3 select build arch 32bit or 64bit
- ./v4l/tbs-x86.sh
or
- ./v4l/tbs-x86_64.sh
I.4 build and install the driver:
- make && make install
I.5 reboot in order to load the newly installed driver:
- shutdown -r now
1.6 By default the TBS drivers will use the old-style APIC controllers, which can result in multiple devices using the same IRQ, which can sometimes cause system instability. To check whether this is the case, run
- cat /proc/interrupts
and note whether the "SAA716x Core" entry is shared with any other devices. If so, or if you simply wish to use the newer style interrupts in order to gain better reliability, see this article:
