-This class of cards has a bt878a as the PCI interface, and
-require the bttv driver.
+1) General information
+======================
-Please pay close attention to the warning about the bttv module
-options below for the DST card.
+This class of cards has a bt878a chip as the PCI interface.
+The different card drivers require the bttv driver to provide the means
+to access the i2c bus and the gpio pins of the bt8xx chipset.
-1) General informations
-=======================
+2) Compilation rules for Kernel >= 2.6.12
+=========================================
-These drivers require the bttv driver to provide the means to access
-the i2c bus and the gpio pins of the bt8xx chipset.
+Enable the following options:
-Because of this, you need to enable
"Device drivers" => "Multimedia devices"
- => "Video For Linux" => "BT848 Video For Linux"
+ => "Video For Linux" => "BT848 Video For Linux"
+"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices"
+ => "DVB for Linux" "DVB Core Support" "Nebula/Pinnacle PCTV/TwinHan PCI Cards"
-2) Loading Modules
-==================
+3) Loading Modules, described by two approaches
+===============================================
In general you need to load the bttv driver, which will handle the gpio and
-i2c communication for us. Next you need the common dvb-bt8xx device driver
-and one frontend driver.
+i2c communication for us, plus the common dvb-bt8xx device driver,
+which is called the backend.
+The frontends for Nebula DigiTV (nxt6000), Pinnacle PCTV Sat (cx24110),
+TwinHan DST + clones (dst and dst-ca) are loaded automatically by the backend.
+For further details about TwinHan DST + clones see /Documentation/dvb/ci.txt.
-The bttv driver will HANG YOUR SYSTEM IF YOU DO NOT SPECIFY THE CORRECT
-CARD ID!
+3a) The manual approach
+-----------------------
-(If you don't get your card running and you suspect that the card id you're
-using is wrong, have a look at "bttv-cards.c" for a list of possible card
-ids.)
+Loading modules:
+modprobe bttv
+modprobe dvb-bt8xx
-Pay attention to failures when you load the frontend drivers
-(e.g. dmesg, /var/log/messages).
+Unloading modules:
+modprobe -r dvb-bt8xx
+modprobe -r bttv
-3a) Nebula / Pinnacle PCTV
+3b) The automatic approach
--------------------------
- $ modprobe bttv i2c_hw=1 card=0x68
- $ modprobe dvb-bt8xx
-
-For Nebula cards use the "nxt6000" frontend driver:
- $ modprobe nxt6000
+If not already done by installation, place a line either in
+/etc/modules.conf or in /etc/modprobe.conf containing this text:
+alias char-major-81 bttv
-For Pinnacle PCTV cards use the "cx24110" frontend driver:
- $ modprobe cx24110
+Then place a line in /etc/modules containing this text:
+dvb-bt8xx
-3b) TwinHan
------------
-
- $ modprobe bttv i2c_hw=1 card=0x71
- $ modprobe dvb-bt8xx
- $ modprobe dst
-
-The value 0x71 will override the PCI type detection for dvb-bt8xx, which
-is necessary for TwinHan cards.#
-
-If you're having an older card (blue color circuit) and card=0x71 locks your
-machine, try using 0x68, too. If that does not work, ask on the DVB mailing list.
-
-The DST module takes a couple of useful parameters, in case the
-dst drivers fails to detect your type of card correctly.
-
-dst_type takes values 0 (satellite), 1 (terrestial TV), 2 (cable).
-
-dst_type_flags takes bit combined values:
-1 = new tuner type packets. You can use this if your card is detected
- and you have debug and you continually see the tuner packets not
- working (make sure not a basic problem like dish alignment etc.)
-
-2 = TS 204. If your card tunes OK, but the picture is terrible, seemingly
- breaking up in one half continually, and crc fails a lot, then
- this is worth a try (or trying to turn off)
-
-4 = has symdiv. Some cards, mostly without new tuner packets, require
- a symbol division algorithm. Doesn't apply to terrestial TV.
-
-You can also specify a value to have the autodetected values turned off
-(e.g. 0). The autodected values are determined bythe cards 'response
-string' which you can see in your logs e.g.
-
-dst_check_ci: recognize DST-MOT
-
-or
-
-dst_check_ci: unable to recognize DSTXCI or STXCI
+Reboot your system and have fun!
