+HOWTO: Get An Avermedia DVB-T working under Linux
+ ______________________________________________
+
+ Table of Contents
+ Assumptions and Introduction
+ The Avermedia DVB-T
+ Getting the card going
+ Receiving DVB-T in Australia
+ Known Limitations
+ Further Update
+
+Assumptions and Introduction
+
+ It is assumed that the reader understands the basic structure
+ of the Linux Kernel DVB drivers and the general principles of
+ Digital TV.
+
+ One significant difference between Digital TV and Analogue TV
+ that the unwary (like myself) should consider is that,
+ although the component structure of budget DVB-T cards are
+ substantially similar to Analogue TV cards, they function in
+ substantially different ways.
+
+ The purpose of an Analogue TV is to receive and display an
+ Analogue Television signal. An Analogue TV signal (otherwise
+ known as composite video) is an analogue encoding of a
+ sequence of image frames (25 per second) rasterised using an
+ interlacing technique. Interlacing takes two fields to
+ represent one frame. Computers today are at their best when
+ dealing with digital signals, not analogue signals and a
+ composite video signal is about as far removed from a digital
+ data stream as you can get. Therefore, an Analogue TV card for
+ a PC has the following purpose:
+
+ * Tune the receiver to receive a broadcast signal
+ * demodulate the broadcast signal
+ * demultiplex the analogue video signal and analogue audio
+ signal (note some countries employ a digital audio signal
+ embedded within the modulated composite analogue signal -
+ NICAM.)
+ * digitize the analogue video signal and make the resulting
+ datastream available to the data bus.
+
+ The digital datastream from an Analogue TV card is generated
+ by circuitry on the card and is often presented uncompressed.
+ For a PAL TV signal encoded at a resolution of 768x576 24-bit
+ color pixels over 25 frames per second - a fair amount of data
+ is generated and must be processed by the PC before it can be
+ displayed on the video monitor screen. Some Analogue TV cards
+ for PCs have onboard MPEG2 encoders which permit the raw
+ digital data stream to be presented to the PC in an encoded
+ and compressed form - similar to the form that is used in
+ Digital TV.
+
+ The purpose of a simple budget digital TV card (DVB-T,C or S)
+ is to simply:
+
+ * Tune the received to receive a broadcast signal.
+ * Extract the encoded digital datastream from the broadcast
+ signal.
+ * Make the encoded digital datastream (MPEG2) available to
+ the data bus.
+
+ The significant difference between the two is that the tuner
+ on the analogue TV card spits out an Analogue signal, whereas
+ the tuner on the digital TV card spits out a compressed
+ encoded digital datastream. As the signal is already
+ digitised, it is trivial to pass this datastream to the PC
+ databus with minimal additional processing and then extract
+ the digital video and audio datastreams passing them to the
+ appropriate software or hardware for decoding and viewing.
+ _________________________________________________________
+
+The Avermedia DVB-T
+
+ The Avermedia DVB-T is a budget PCI DVB card. It has 3 inputs:
+
+ * RF Tuner Input
+ * Composite Video Input (RCA Jack)
+ * SVIDEO Input (Mini-DIN)
+
+ The RF Tuner Input is the input to the tuner module of the
+ card. The Tuner is otherwise known as the "Frontend" . The
+ Frontend of the Avermedia DVB-T is a Microtune 7202D. A timely
+ post to the linux-dvb mailing list ascertained that the
+ Microtune 7202D is supported by the sp887x driver which is
+ found in the dvb-hw CVS module.
+
+ The DVB-T card is based around the BT878 chip which is a very
+ common multimedia bridge and often found on Analogue TV cards.
+ There is no on-board MPEG2 decoder, which means that all MPEG2
+ decoding must be done in software, or if you have one, on an
+ MPEG2 hardware decoding card or chipset.
+ _________________________________________________________
+
+Getting the card going
+
+ In order to fire up the card, it is necessary to load a number
+ of modules from the DVB driver set. Prior to this it will have
+ been necessary to download these drivers from the linuxtv CVS
+ server and compile them successfully.
+
+ Depending on the card's feature set, the Device Driver API for
+ DVB under Linux will expose some of the following device files
+ in the /dev tree:
+
+ * /dev/dvb/adapter0/audio0
+ * /dev/dvb/adapter0/ca0
+ * /dev/dvb/adapter0/demux0
+ * /dev/dvb/adapter0/dvr0
+ * /dev/dvb/adapter0/frontend0
+ * /dev/dvb/adapter0/net0
+ * /dev/dvb/adapter0/osd0
+ * /dev/dvb/adapter0/video0
+
+ The primary device nodes that we are interested in (at this
+ stage) for the Avermedia DVB-T are:
+
+ * /dev/dvb/adapter0/dvr0
+ * /dev/dvb/adapter0/frontend0
+
+ The dvr0 device node is used to read the MPEG2 Data Stream and
+ the frontend0 node is used to tune the frontend tuner module.
+
+ At this stage, it has not been able to ascertain the
+ functionality of the remaining device nodes in respect of the
+ Avermedia DVBT. However, full functionality in respect of
+ tuning, receiving and supplying the MPEG2 data stream is
+ possible with the currently available versions of the driver.
+ It may be possible that additional functionality is available
+ from the card (i.e. viewing the additional analogue inputs
+ that the card presents), but this has not been tested yet. If
+ I get around to this, I'll update the document with whatever I
+ find.
+
+ To power up the card, load the following modules in the
+ following order:
+
+ * modprobe bttv (normally loaded automatically)
+ * modprobe dvb-bt8xx (or place dvb-bt8xx in /etc/modules)
+
+ Insertion of these modules into the running kernel will
+ activate the appropriate DVB device nodes. It is then possible
+ to start accessing the card with utilities such as scan, tzap,
+ dvbstream etc.
+
+ The frontend module sp887x.o, requires an external firmware.
+ Please use the command "get_dvb_firmware sp887x" to download
+ it. Then copy it to /usr/lib/hotplug/firmware or /lib/firmware/
+ (depending on configuration of firmware hotplug).
+
+Receiving DVB-T in Australia
+
+ I have no experience of DVB-T in other countries other than
+ Australia, so I will attempt to explain how it works here in
+ Melbourne and how this affects the configuration of the DVB-T
+ card.
+
+ The Digital Broadcasting Australia website has a Reception
+ locatortool which provides information on transponder channels
+ and frequencies. My local transmitter happens to be Mount
+ Dandenong.
+
+ The frequencies broadcast by Mount Dandenong are:
+
+ Table 1. Transponder Frequencies Mount Dandenong, Vic, Aus.
+ Broadcaster Channel Frequency
+ ABC VHF 12 226.5 MHz
+ TEN VHF 11 219.5 MHz
+ NINE VHF 8 191.625 MHz
+ SEVEN VHF 6 177.5 MHz
+ SBS UHF 29 536.5 MHz
+
+ The Scan utility has a set of compiled-in defaults for various
+ countries and regions, but if they do not suit, or if you have
+ a pre-compiled scan binary, you can specify a data file on the
+ command line which contains the transponder frequencies. Here
+ is a sample file for the above channel transponders:
+# Data file for DVB scan program
+#
+# C Frequency SymbolRate FEC QAM
+# S Frequency Polarisation SymbolRate FEC
+# T Frequency Bandwidth FEC FEC2 QAM Mode Guard Hier
+T 226500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
+T 191625000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
+T 219500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
+T 177500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
+T 536500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
+
+ The defaults for the transponder frequency and other
+ modulation parameters were obtained from www.dba.org.au.
+
+ When Scan runs, it will output channels.conf information for
+ any channel's transponders which the card's frontend can lock
+ onto. (i.e. any whose signal is strong enough at your
+ antenna).
+
+ Here's my channels.conf file for anyone who's interested:

+ _________________________________________________________
+
+Known Limitations
+
+ At present I can say with confidence that the frontend tunes
+ via /dev/dvb/adapter{x}/frontend0 and supplies an MPEG2 stream
+ via /dev/dvb/adapter{x}/dvr0. I have not tested the
+ functionality of any other part of the card yet. I will do so
+ over time and update this document.
+
+ There are some limitations in the i2c layer due to a returned
+ error message inconsistency. Although this generates errors in
+ dmesg and the system logs, it does not appear to affect the
+ ability of the frontend to function correctly.
+ _________________________________________________________
+
+Further Update
+
+ dvbstream and VideoLAN Client on windows works a treat with
+ DVB, in fact this is currently serving as my main way of
+ viewing DVB-T at the moment. Additionally, VLC is happily
+ decoding HDTV signals, although the PC is dropping the odd
+ frame here and there - I assume due to processing capability -
+ as all the decoding is being done under windows in software.
+
+ Many thanks to Nigel Pearson for the updates to this document
+ since the recent revision of the driver.

+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" => "Enable Video for Linux API 1 (DEPRECATED)"
+b.)"Device drivers" => "Multimedia devices" => "Video For Linux" => "Video Capture Adapters" => "BT848 Video For Linux"
+c.)"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices" => "DVB for Linux" "DVB Core Support" "Bt8xx based PCI Cards"
+
+Please use the following options with care as deselection of drivers which are in fact necessary
+may result in DVB devices that cannot be tuned due to lack of driver support:
+You can save RAM by deselecting every frontend module that your DVB card does not need.
+
+First please remove the static dependency of DVB card drivers on all frontend modules for all possible card variants by enabling:
+d.) "Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices"
+ => "DVB for Linux" "DVB Core Support" "Load and attach frontend modules as needed"
+
+If you know the frontend driver that your card needs please enable:
+e.)"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices"
+ => "DVB for Linux" "DVB Core Support" "Customise DVB Frontends" => "Customise the frontend modules to build"
+ Then please select your card-specific frontend module.
+
+2) Loading Modules
+==================
+
+Regular case: If the bttv driver detects a bt8xx-based DVB card, all frontend and backend modules will be loaded automatically.
+Exceptions are:
+- Old TwinHan DST cards or clones with or without CA slot and not containing an Eeprom.
+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 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
+
+For a full list of card ID's please see Documentation/video4linux/CARDLIST.bttv.
+In case of further problems please subscribe and send questions to the mailing list: linux-dvb@linuxtv.org.
+
+2c) Probing the cards with broken PCI subsystem ID
+--------------------------------------------------
+There are some TwinHan cards that the EEPROM has become corrupted for some
+reason. The cards do not have correct PCI subsystem ID. But we can force
+probing the cards with broken PCI subsystem ID
+
+ $ echo 109e 0878 $subvendor $subdevice > \
+ /sys/bus/pci/drivers/bt878/new_id
+

+Hardware supported by the linuxtv.org DVB drivers
+=================================================
+
+ Generally, the DVB hardware manufacturers frequently change the
+ frontends (i.e. tuner / demodulator units) used, usually without
+ changing the product name, revision number or specs. Some cards
+ are also available in versions with different frontends for
+ DVB-S/DVB-C/DVB-T. Thus the frontend drivers are listed separately.
+
+ Note 1: There is no guarantee that every frontend driver works
+ out of the box with every card, because of different wiring.
+
+ Note 2: The demodulator chips can be used with a variety of
+ tuner/PLL chips, and not all combinations are supported. Often
+ the demodulator and tuner/PLL chip are inside a metal box for
+ shielding, and the whole metal box has its own part number.
+

+* For the user
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+NOTE: This document describes the usage of the high level CI API as
+in accordance to the Linux DVB API. This is a not a documentation for the,
+existing low level CI API.
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To utilize the High Level CI capabilities,
+
+(1*) This point is valid only for the Twinhan/clones
+ For the Twinhan/Twinhan clones, the dst_ca module handles the CI
+ hardware handling.This module is loaded automatically if a CI
+ (Common Interface, that holds the CAM (Conditional Access Module)
+ is detected.
+
+(2) one requires a userspace application, ca_zap. This small userland
+ application is in charge of sending the descrambling related information
+ to the CAM.
+
+This application requires the following to function properly as of now.
+
+ (a) Tune to a valid channel, with szap.
+ eg: $ szap -c channels.conf -r "TMC" -x
+
+ (b) a channels.conf containing a valid PMT PID
+ eg: TMC:11996:h:0:27500:278:512:650:321
+
+ here 278 is a valid PMT PID. the rest of the values are the
+ same ones that szap uses.
+
+ (c) after running a szap, you have to run ca_zap, for the
+ descrambler to function,
+ eg: $ ca_zap channels.conf "TMC"
+
+ (d) Hopefully enjoy your favourite subscribed channel as you do with
+ a FTA card.
+
+(3) Currently ca_zap, and dst_test, both are meant for demonstration
+ purposes only, they can become full fledged applications if necessary.
+
+
+* Cards that fall in this category
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+At present the cards that fall in this category are the Twinhan and its
+clones, these cards are available as VVMER, Tomato, Hercules, Orange and
+so on.
+
+* CI modules that are supported
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The CI module support is largely dependent upon the firmware on the cards
+Some cards do support almost all of the available CI modules. There is
+nothing much that can be done in order to make additional CI modules
+working with these cards.
+
+Modules that have been tested by this driver at present are
+
+(1) Irdeto 1 and 2 from SCM
+(2) Viaccess from SCM
+(3) Dragoncam
+
+* The High level CI API
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+* For the programmer
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+With the High Level CI approach any new card with almost any random
+architecture can be implemented with this style, the definitions
+inside the switch statement can be easily adapted for any card, thereby
+eliminating the need for any additional ioctls.
+
+The disadvantage is that the driver/hardware has to manage the rest. For
+the application programmer it would be as simple as sending/receiving an
+array to/from the CI ioctls as defined in the Linux DVB API. No changes
+have been made in the API to accommodate this feature.
+
+
+* Why the need for another CI interface ?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+This is one of the most commonly asked question. Well a nice question.
+Strictly speaking this is not a new interface.
+
+The CI interface is defined in the DVB API in ca.h as
+
+typedef struct ca_slot_info {
+ int num; /* slot number */
+
+ int type; /* CA interface this slot supports */
+#define CA_CI 1 /* CI high level interface */
+#define CA_CI_LINK 2 /* CI link layer level interface */
+#define CA_CI_PHYS 4 /* CI physical layer level interface */
+#define CA_DESCR 8 /* built-in descrambler */
+#define CA_SC 128 /* simple smart card interface */
+
+ unsigned int flags;
+#define CA_CI_MODULE_PRESENT 1 /* module (or card) inserted */
+#define CA_CI_MODULE_READY 2
+} ca_slot_info_t;
+
+
+
+This CI interface follows the CI high level interface, which is not
+implemented by most applications. Hence this area is revisited.
+
+This CI interface is quite different in the case that it tries to
+accommodate all other CI based devices, that fall into the other categories.
+
+This means that this CI interface handles the EN50221 style tags in the
+Application layer only and no session management is taken care of by the
+application. The driver/hardware will take care of all that.
+
+This interface is purely an EN50221 interface exchanging APDU's. This
+means that no session management, link layer or a transport layer do
+exist in this case in the application to driver communication. It is
+as simple as that. The driver/hardware has to take care of that.
+
+
+With this High Level CI interface, the interface can be defined with the
+regular ioctls.
+
+All these ioctls are also valid for the High level CI interface
+
+#define CA_RESET _IO('o', 128)
+#define CA_GET_CAP _IOR('o', 129, ca_caps_t)
+#define CA_GET_SLOT_INFO _IOR('o', 130, ca_slot_info_t)
+#define CA_GET_DESCR_INFO _IOR('o', 131, ca_descr_info_t)
+#define CA_GET_MSG _IOR('o', 132, ca_msg_t)
+#define CA_SEND_MSG _IOW('o', 133, ca_msg_t)
+#define CA_SET_DESCR _IOW('o', 134, ca_descr_t)
+#define CA_SET_PID _IOW('o', 135, ca_pid_t)
+
+
+On querying the device, the device yields information thus
+
+CA_GET_SLOT_INFO

+Descriptors(Program Level)=[ 09 06 06 04 05 50 ff f1]

+
+(20) ES type=[2] ES pid=[201] ES length =[0 (0x0)]
+(25) ES type=[4] ES pid=[301] ES length =[0 (0x0)]
+ca_message length is 25 (0x19) bytes
+EN50221 CA MSG=[ 9f 80 32 19 03 01 2d d1 f0 08 01 09 06 06 04 05 50 ff f1 02 e0 c9 00 00 04 e1 2d 00 00]
+
+
+Not all ioctl's are implemented in the driver from the API, the other
+features of the hardware that cannot be implemented by the API are achieved
+using the CA_GET_MSG and CA_SEND_MSG ioctls. An EN50221 style wrapper is
+used to exchange the data to maintain compatibility with other hardware.
+
+
+/* a message to/from a CI-CAM */
+typedef struct ca_msg {
+ unsigned int index;
+ unsigned int type;
+ unsigned int length;
+ unsigned char msg[256];
+} ca_msg_t;
+
+
+The flow of data can be described thus,

+Documentation for dvb-usb-framework module and its devices
+
+Idea behind the dvb-usb-framework
+=================================
+
+In March 2005 I got the new Twinhan USB2.0 DVB-T device. They provided specs and a firmware.
+
+Quite keen I wanted to put the driver (with some quirks of course) into dibusb.
+After reading some specs and doing some USB snooping, it realized, that the
+dibusb-driver would be a complete mess afterwards. So I decided to do it in a
+different way: With the help of a dvb-usb-framework.
+
+The framework provides generic functions (mostly kernel API calls), such as:
+
+- Transport Stream URB handling in conjunction with dvb-demux-feed-control
+ (bulk and isoc are supported)
+- registering the device for the DVB-API
+- registering an I2C-adapter if applicable
+- remote-control/input-device handling
+- firmware requesting and loading (currently just for the Cypress USB
+ controllers)
+- other functions/methods which can be shared by several drivers (such as
+ functions for bulk-control-commands)
+- TODO: a I2C-chunker. It creates device-specific chunks of register-accesses
+ depending on length of a register and the number of values that can be
+ multi-written and multi-read.
+
+The source code of the particular DVB USB devices does just the communication
+with the device via the bus. The connection between the DVB-API-functionality
+is done via callbacks, assigned in a static device-description (struct
+dvb_usb_device) each device-driver has to have.
+
+For an example have a look in drivers/media/usb/dvb-usb/vp7045*.
+
+Objective is to migrate all the usb-devices (dibusb, cinergyT2, maybe the
+ttusb; flexcop-usb already benefits from the generic flexcop-device) to use
+the dvb-usb-lib.
+
+TODO: dynamic enabling and disabling of the pid-filter in regard to number of
+feeds requested.

+ 2004-05-14 - firmware loader is working
+ 2004-05-11 - start writing the driver
+
+1. How to use?
+1.1. Firmware
+
+Most of the USB drivers need to download a firmware to the device before start
+working.
+
+Have a look at the Wikipage for the DVB-USB-drivers to find out, which firmware
+you need for your device:
+
+https://linuxtv.org/wiki/index.php/DVB_USB
+
+1.2. Compiling
+
+Since the driver is in the linux kernel, activating the driver in
+your favorite config-environment should sufficient. I recommend
+to compile the driver as module. Hotplug does the rest.
+
+If you use dvb-kernel enter the build-2.6 directory run 'make' and 'insmod.sh
+load' afterwards.
+
+1.3. Loading the drivers
+
+Hotplug is able to load the driver, when it is needed (because you plugged
+in the device).
+
+If you want to enable debug output, you have to load the driver manually and
+from within the dvb-kernel cvs repository.
+
+first have a look, which debug level are available:
+
+modinfo dvb-usb
+modinfo dvb-usb-vp7045
+etc.
+
+modprobe dvb-usb debug=<level>
+modprobe dvb-usb-vp7045 debug=<level>
+etc.
+
+should do the trick.
+
+When the driver is loaded successfully, the firmware file was in
+the right place and the device is connected, the "Power"-LED should be
+turned on.
+
+At this point you should be able to start a dvb-capable application. I'm use
+(t|s)zap, mplayer and dvbscan to test the basics. VDR-xine provides the
+long-term test scenario.
+
+2. Known problems and bugs
+
+- Don't remove the USB device while running an DVB application, your system
+ will go crazy or die most likely.
+
+2.1. Adding support for devices
+
+TODO
+
+2.2. USB1.1 Bandwidth limitation
+
+A lot of the currently supported devices are USB1.1 and thus they have a
+maximum bandwidth of about 5-6 MBit/s when connected to a USB2.0 hub.
+This is not enough for receiving the complete transport stream of a
+DVB-T channel (which is about 16 MBit/s). Normally this is not a
+problem, if you only want to watch TV (this does not apply for HDTV),
+but watching a channel while recording another channel on the same
+frequency simply does not work very well. This applies to all USB1.1
+DVB-T devices, not just the dvb-usb-devices)
+
+The bug, where the TS is distorted by a heavy usage of the device is gone
+definitely. All dvb-usb-devices I was using (Twinhan, Kworld, DiBcom) are

+Some very frequently asked questions about linuxtv-dvb
+
+1. The signal seems to die a few seconds after tuning.
+
+ It's not a bug, it's a feature. Because the frontends have
+ significant power requirements (and hence get very hot), they
+ are powered down if they are unused (i.e. if the frontend device
+ is closed). The dvb-core.o module parameter "dvb_shutdown_timeout"
+ allow you to change the timeout (default 5 seconds). Setting the
+ timeout to 0 disables the timeout feature.
+
+2. How can I watch TV?
+
+ The driver distribution includes some simple utilities which
+ are mainly intended for testing and to demonstrate how the
+ DVB API works.
+
+ Depending on whether you have a DVB-S, DVB-C or DVB-T card, use
+ apps/szap/szap, czap or tzap. You must supply a channel list
+ in ~/.[sct]zap/channels.conf. If you are lucky you can just copy
+ one of the supplied channel lists, or you can create a new one
+ by running apps/scan/scan. If you run scan on an unknown network
+ you might have to supply some start data in apps/scan/initial.h.
+
+ If you have a card with a built-in hardware MPEG-decoder the
+ drivers create a video4linux device (/dev/v4l/video0) which
+ you can use to watch TV with any v4l application. xawtv is known
+ to work. Note that you cannot change channels with xawtv, you
+ have to zap using [sct]zap. If you want a nice application for
+ TV watching and record/playback, have a look at VDR.
+
+ If your card does not have a hardware MPEG decoder you need
+ a software MPEG decoder. Mplayer or xine are known to work.
+ Newsflash: MythTV also has DVB support now.
+ Note: Only very recent versions of Mplayer and xine can decode.
+ MPEG2 transport streams (TS) directly. Then, run
+ '[sct]zap channelname -r' in one xterm, and keep it running,
+ and start 'mplayer - < /dev/dvb/adapter0/dvr0' or
+ 'xine stdin://mpeg2 < /dev/dvb/adapter0/dvr0' in a second xterm.
+ That's all far from perfect, but it seems no one has written
+ a nice DVB application which includes a builtin software MPEG
+ decoder yet.
+
+ Newsflash: Newest xine directly supports DVB. Just copy your
+ channels.conf to ~/.xine and start 'xine dvb://', or select
+ the DVB button in the xine GUI. Channel switching works using the
+ numpad pgup/pgdown (NP9 / NP3) keys to scroll through the channel osd
+ menu and pressing numpad-enter to switch to the selected channel.
+
+ Note: Older versions of xine and mplayer understand MPEG program
+ streams (PS) only, and can be used in conjunction with the
+ ts2ps tool from the Metzler Brother's dvb-mpegtools package.
+
+3. Which other DVB applications exist?

+
+ http://dvbsnoop.sourceforge.net/
+ DVB sniffer program to monitor, analyze, debug, dump
+ or view dvb/mpeg/dsm-cc/mhp stream information (TS,
+ PES, SECTION)
+
+4. Can't get a signal tuned correctly
+
+ If you are using a Technotrend/Hauppauge DVB-C card *without* analog
+ module, you might have to use module parameter adac=-1 (dvb-ttpci.o).
+
+5. The dvb_net device doesn't give me any packets at all
+
+ Run tcpdump on the dvb0_0 interface. This sets the interface
+ into promiscuous mode so it accepts any packets from the PID
+ you have configured with the dvbnet utility. Check if there
+ are any packets with the IP addr and MAC addr you have
+ configured with ifconfig.
+
+ If tcpdump doesn't give you any output, check the statistics
+ which ifconfig outputs. (Note: If the MAC address is wrong,
+ dvb_net won't get any input; thus you have to run tcpdump
+ before checking the statistics.) If there are no packets at
+ all then maybe the PID is wrong. If there are error packets,
+ then either the PID is wrong or the stream does not conform to
+ the MPE standard (EN 301 192, http://www.etsi.org/). You can
+ use e.g. dvbsnoop for debugging.
+
+6. The dvb_net device doesn't give me any multicast packets
+
+ Check your routes if they include the multicast address range.
+ Additionally make sure that "source validation by reversed path
+ lookup" is disabled:
+ $ "echo 0 > /proc/sys/net/ipv4/conf/dvb0/rp_filter"
+
+7. What the hell are all those modules that need to be loaded?
+
+ For a dvb-ttpci av7110 based full-featured card the following
+ modules are loaded:
+
+ - videodev: Video4Linux core module. This is the base module that
+ gives you access to the "analog" tv picture of the av7110 mpeg2
+ decoder.
+
+ - v4l2-common: common functions for Video4Linux-2 drivers
+
+ - v4l1-compat: backward compatibility layer for Video4Linux-1 legacy
+ applications
+
+ - dvb-core: DVB core module. This provides you with the
+ /dev/dvb/adapter entries
+
+ - saa7146: SAA7146 core driver. This is need to access any SAA7146
+ based card in your system.
+
+ - saa7146_vv: SAA7146 video and vbi functions. These are only needed
+ for full-featured cards.
+
+ - videobuf-dma-sg: capture helper module for the saa7146_vv driver. This
+ one is responsible to handle capture buffers.
+
+ - dvb-ttpci: The main driver for AV7110 based, full-featured
+ DVB-S/C/T cards

+How to set up the Technisat/B2C2 Flexcop devices
+================================================
+
+1) Find out what device you have
+================================
+
+Important Notice: The driver does NOT support Technisat USB 2 devices!
+
+First start your linux box with a shipped kernel:
+lspci -vvv for a PCI device (lsusb -vvv for an USB device) will show you for example:
+02:0b.0 Network controller: Techsan Electronics Co Ltd B2C2 FlexCopII DVB chip /
+ Technisat SkyStar2 DVB card (rev 02)
+
+dmesg | grep frontend may show you for example:
+DVB: registering frontend 0 (Conexant CX24123/CX24109)...
+
+2) Kernel compilation:
+======================
+
+If the Flexcop / Technisat is the only DVB / TV / Radio device in your box
+ get rid of unnecessary modules and check this one:
+"Multimedia support" => "Customise analog and hybrid tuner modules to build"
+In this directory uncheck every driver which is activated there
+ (except "Simple tuner support" for ATSC 3rd generation only -> see case 9 please).
+
+Then please activate:
+2a) Main module part:
+"Multimedia support" => "DVB/ATSC adapters"

+a.) => "Technisat/B2C2 Air/Sky/Cable2PC PCI" (PCI card) or
+b.) => "Technisat/B2C2 Air/Sky/Cable2PC USB" (USB 1.1 adapter)
+ and for troubleshooting purposes:
+c.) => "Enable debug for the B2C2 FlexCop drivers"
+
+2b) Frontend / Tuner / Demodulator module part:
+"Multimedia support" => "DVB/ATSC adapters"
+ => "Customise the frontend modules to build" "Customise DVB frontends" =>
+
+1.) SkyStar DVB-S Revision 2.3:

+The DVB subsystem currently registers to the sysfs subsystem using the
+"class_simple" interface.
+
+This means that only the basic information like module loading parameters
+are presented through sysfs. Other things that might be interesting are
+currently *not* available.
+
+Nevertheless it's now possible to add proper udev rules so that the
+DVB device nodes are created automatically.
+
+We assume that you have udev already up and running and that have been
+creating the DVB device nodes manually up to now due to the missing sysfs
+support.
+
+0. Don't forget to disable your current method of creating the
+device nodes manually.
+
+1. Unfortunately, you'll need a helper script to transform the kernel
+sysfs device name into the well known dvb adapter / device naming scheme.
+The script should be called "dvb.sh" and should be placed into a script
+dir where udev can execute it, most likely /etc/udev/scripts/
+
+So, create a new file /etc/udev/scripts/dvb.sh and add the following:
+------------------------------schnipp------------------------------------------------
+#!/bin/sh
+/bin/echo $1 | /bin/sed -e 's,dvb\([0-9]\)\.\([^0-9]*\)\([0-9]\),dvb/adapter\1/\2\3,'
+------------------------------schnipp------------------------------------------------
+
+Don't forget to make the script executable with "chmod".
+
+1. You need to create a proper udev rule that will create the device nodes
+like you know them. All real distributions out there scan the /etc/udev/rules.d
+directory for rule files. The main udev configuration file /etc/udev/udev.conf
+will tell you the directory where the rules are, most likely it's /etc/udev/rules.d/
+
+Create a new rule file in that directory called "dvb.rule" and add the following line:
+------------------------------schnipp------------------------------------------------
+KERNEL="dvb*", PROGRAM="/etc/udev/scripts/dvb.sh %k", NAME="%c"
+------------------------------schnipp------------------------------------------------
+
+If you want more control over the device nodes (for example a special group membership)
+have a look at "man udev".
+
+For every device that registers to the sysfs subsystem with a "dvb" prefix,
+the helper script /etc/udev/scripts/dvb.sh is invoked, which will then
+create the proper device node in your /dev/ directory.
