Support for PCI cards based on the Bt8xx PCI bridge. Examples are
the Nebula cards, the Pinnacle PCTV cards, and Twinhan DST cards.
Since these cards have no MPEG decoder onboard, they transmit
only compressed MPEG data over the PCI bus, so you need
an external software decoder to watch TV on your computer.
Say Y if you own such a device and want to use it.

Used in such cards as the VP-1020/1030, Twinhan DST,
VVmer TV@SAT. Say Y when you want to support frontends
using this asic.
This module requires the dvb-bt8xx driver and dvb bt878
module.

help
This driver needs a copy of the Avermedia firmware. The version tested
is part of the Avermedia DVB-T 1.3.26.3 Application. This can be downloaded
from the Avermedia web site.
If the software is installed in Windows the file will be in the
/Program Files/AVerTV DVB-T/ directory and is called sc_main.mc.
Alternatively it can "extracted" from the install cab files but this will have
to be done in windows as I don't know of a linux version of extract.exe.
Copy this file to /etc/dvb/sc_main.mc. With this version of the file the first
10 bytes are discarded and the next 0x4000 loaded. This may change in future
versions.
