How to get the bt8xx cards working
==================================
1) General information
======================
This class of cards has a bt878a as the PCI interface, and require the bttv driver
for accessing the i2c bus and the gpio pins of the bt8xx chipset.
Please see Documentation/dvb/cards.txt => o Cards based on the Conexant Bt8xx PCI bridge:
Compiling kernel please enable:
a.)"Device drivers" => "Multimedia devices" => "Video For Linux" => "BT848 Video For Linux"
b.)"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices"
=> "DVB for Linux" "DVB Core Support" "Bt8xx based PCI Cards"
2) Loading Modules
==================
In default cases bttv is loaded automatically.
To load the backend either place dvb-bt8xx in etc/modules, or apply manually:
$ modprobe dvb-bt8xx
All frontends will be loaded automatically.
People running udev please see Documentation/dvb/udev.txt.
In the following cases overriding the PCI type detection for dvb-bt8xx might be necessary:
2a) Running TwinHan and Clones
------------------------------
$ modprobe bttv card=113
$ modprobe dvb-bt8xx
$ modprobe dst
Useful parameters for verbosity level and debugging the dst module:
verbose=0: messages are disabled
1: only error messages are displayed
2: notifications are displayed
3: other useful messages are displayed
4: debug setting
dst_addons=0: card is a free to air (FTA) card only
0x20: card has a conditional access slot for scrambled channels
The autodetected values are determined by the cards' "response string".
In your logs see f. ex.: dst_get_device_id: Recognize [DSTMCI].
For bug reports please send in a complete log with verbose=4 activated.
Please also see Documentation/dvb/ci.txt.
2b) Running multiple cards
--------------------------
Examples of card ID's:
Pinnacle PCTV Sat: 94
Nebula Electronics Digi TV: 104
pcHDTV HD-2000 TV: 112
Twinhan DST and clones: 113
Avermedia AverTV DVB-T 771: 123
Avermedia AverTV DVB-T 761: 124
DViCO FusionHDTV DVB-T Lite: 128
DViCO FusionHDTV 5 Lite: 135
Notice: The order of the card ID should be uprising:
Example:
$ modprobe bttv card=113 card=135
$ modprobe dvb-bt8xx
For a full list of card ID's please see Documentation/video4linux/CARDLIST.bttv.
In case of further problems send questions to the mailing list: www.linuxdvb.org.
