The BTTV HOWTO Howard Shane Revision History Revision 0.9 Initial rewrite 2005−01−29 Revised by: jhs This document was written to assist the reader in the steps necessary to configure and use a video tuner card based on the popular Bt848 and Bt878 chipsets within the Linux operating system.

1. Introduction This document was written to assist the reader in setting up and configuring TV tuner cards based on the Bt848 or Bt878 chipsets in the Linux operating system. It outlines how to enable the necessary kernel and/or software support and various television applications and software methods of capture usable with your device.
The BTTV HOWTO 1.5. Feedback Please send any information you may feel important to the following email address: , whether you have a correction, addition or update. I welcome suggestions on how to improve this document. 1.6.
2. The BTTV Hardware 2.1. Bttv Basics If you haven't figured it out by now, this document deals with the Linux−specific configuration of frame grabber cards that include the Conexant Bt848 and related family of video decoder chips, collectively referred to as the "Bt8x8" chipset. You can probably see the Bt8x8 chip (it's usually labelled as such) embedded on your TV card upon inspection, in addition to other chips which you should probably make note of before installation in case there are problems later.
The BTTV HOWTO to control the input with your mixer from your primary sound card as well as record (see Appendix D for more information on recording). Alternatively you can use external speakers connected to the line out of your Bt8x8 card. 2.
3. Enabling Support for Your Bt8x8 Hardware in Linux 3.1. The Bttv Driver Drivers for Bt8x8−based hardware have been a part of the Linux kernel since version 2.2.0, and are likely to be already enabled in your running kernel if you have not recompiled or otherwise replaced your system's stock kernel with a custom version.
The BTTV HOWTO $ ls −R /lib/modules/`uname −r`/kernel Where `uname −r`, surrounded by forward tick marks, is your kernel version number. The following output is an example of what you might find in a Bttv−ready kernel, where everything is loaded as a module (edited for brevity): /lib/modules/2.6.8/kernel/drivers/media/video: btcx−risc.ko ir−kbd−i2c.ko tda9875.ko tvaudio.ko bttv.ko msp3400.ko tda9887.ko v4l1−compat.ko ir−kbd−gpio.ko tda7432.ko tuner.ko v4l2−common.ko video−buf.ko videodev.
The BTTV HOWTO If you are running a 2.4 series kernel, btaudio in the OSS "Sound" category is optional if you want to use external speakers attached to the the card's audio out jack, and either (or both) OSS or ALSA sound system btaudio drivers in the 2.6+ series. 3.3. Configuration Requirements for Use of your Bttv Hardware Once you know your kernel is enabled you can proceed to some minor tuning that may already be done for you depending on your system and distributor and distribution features. 3.3.1.
The BTTV HOWTO # see http://roadrunner.swansea.uk.linux.org/v4lapi.shtml echo "*** new device names ***" makedev video 0 makedev radio 64 makedev vtx 192 makedev vbi 224 # "*** old device names (for compatibility only) ***" #makedev bttv 0 #makedev bttv−fm 64 #makedev bttv−vbi 224 Simply copy and paste the above into your favorite editing program, save it as MAKEDEV or whatever name you like, make it executable (i.e., chmod u+x MAKEDEV), and then execute it as root: # ./MAKEDEV 3.4.
4. Loading the Modules This section is only for those whose modules don't load automatically and/or correctly. For a complete list of options by module, see Appendix A. 4.1. The Bttv Module Once your card is installed, you can load the bttv module if your kernel hasn't already done it for you. Using the modprobe command as root, type # modprobe bttv The modules videodev and i2c may be required prior to this if you are running a pre−2.4 series kernel.

5. Television Applications Now that your kernel is configured, your devices have been configured, and your modules are inserted, you will also need an application to actually view or capture the images from your card. 5.1. Console−Based Applications 5.1.1. FbTV Fbtv is a console−only mode TV viewing program available for viewing on a framebuffer−video enabled system with a Bt8x8 card. If you don't know what a framebuffer is you can read the Framebuffer HOWTO.
The BTTV HOWTO flags: overlay capture tuner Now that you know your Bt8x8 device is available, try starting Xawtv: $ xawtv −device /dev/video0 Note that some Nvidia cards may confuse xawtv, so if you have one of these be sure to use the −device switch as above. 5.2.2. Motv Motv is a Motif−based rewrite of Xawtv. Other than a more attractive interface, and is also found at the Xawtv homepage. It is otherwise identical to Xawtv. 5.2.3.
A. Optional Arguments for Loading Modules videodev.o −−−−−−−−−−−−−−−−−−−−−−−−−−−−− This is the basic video4linux module, all video drivers (incl. bttv) register themselves here. i2c.o −−−−−−−−−−−−−−−−−−−−−−−− The generic i2c module. It does much of the i2c bus management, all other modules (except videodev.o) use this one. modprobe args: scan=1 scan the bus for i2c devices verbose=0 shut up i2c i2c_debug=1 for debugging, it sticks the whole (software) i2c bus traffic to the syslog bttv.
The BTTV HOWTO stereo card, you probably want to modprobe this one. modprobe args: debug=1/2 print some debug info to the syslog, 2 is more verbose. *tea6300.o −−−−−−−−−−−−−−−−−−−−−−−−−−−−− The driver for the tea6300 fader chip. If you have a stereo card and the msp3400.o doesn't work, you might want to try this one. This chip is seen on most STB TV/FM cards (usually from Gateway OEM sold surplus on auction sites). modprobe args: debug=1 print some debug info to the syslog. *tda8425.
The BTTV HOWTO tuner.o −−−−−−−−−−−−−−−−−−−−−−−−−− The tuner driver. You need this unless you want to use only with a camera or external tuner. modprobe args: debug=1 print some debug info to the syslog type=n type of the tuner chip. n as seen in Section 4 i2c_chardev.o −−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−− Provides a character device for i2c bus access. only, not compiled by default. A. Optional Arguments for Loading Modules Works for 2.1.
B. Bt8x8 Cards by Number These are the option numbers for cards for use with modprobe.This does not boast to be a complete list by any means; it is copied nearly verbatim from the kernel source documentation for bttv. If your card is not listed it may or may not be supported depending on the chipset and accompanying components with which it is constructed.

Cards and Features by Manufacturer MATRIX Vision −−−−−−−−−−−−− MV−Delta − Bt848A − 4 Composite inputs, 1 S−VHS input (shared with 4th composite) − EEPROM http://www.matrix−vision.de/ This card has no tuner but supports all 4 composite (1 shared with an S−VHS input) of the Bt848A. Very nice card if you only have satellite TV but several tuners connected to the card via composite.
The BTTV HOWTO − Bt848 (and others but always in 2 crystal operation???) newer cards have a Bt878 − PAL, SECAM, NTSC or tuner with or without Radio support e.g.: PAL: TDA5737: VHF, hyperband and UHF mixer/oscillator for TV and VCR 3−band tuners TSA5522: 1.

D. Recording Video and Sound with Bttv In addition to the applications referenced in Section 5, recording can be managed from the command line. The issues discussed here with regard to sound capture deal only with the default kernel−2.6 and higher sound system: the Advanced Linux Sound Architecture. The easy part is grabbing the video, for which we will use streamer, available with the Xawtv suite. Sound is another matter, however.
The BTTV HOWTO Now try to record something: $ streamer −p 4 −t 1:00 −r 24 −q −o test.avi −j 90 −f mjpeg −F mono16 ...and you should be recording a sound−enabled avi file. Press [Ctrl]−C to cancel early. Next step is to automate the recording for your very own home−brewed Tivo"! I offer the following script as an example program for automating recording; you can copy and paste it into a file and make it executable (chmod u+x record−tv.sh).
The BTTV HOWTO if [ ! −z $3 ]; then $V4LCTL setchannel $3 fi # Check for vcr dir if [ ! −x $OUTPUT ]; then mkdir $OUTPUT fi DATE=`date +%m−%d−%Y−%H:%M` # Set the AC97 volume to 0 (so we don't hear the sounds) # Get mixer values first PLAY_VOL=`$AMIXER −c 0 cget name='Master Playback Volume' | grep : | sed 's/^.*=\([^,]*\).*$/\1/ CAP_VOL=`$AMIXER −c 0 cget name='PCM Playback Volume' | grep : | sed 's/^.*=\([^,]*\).
E. Enabling The FM Radio for Radio−Equipped Cards FM radio tuners are easily enabled when inserting modules. Simply $ modprobe bttv radio=1 ...or add a similar option to your /etc/modules.conf and you should be set the next time you restart or load the module. You will also need an application to access the radio. I suggest the console based radio, available with the Xawtv suite, or fmtools. For graphical programs, try gnomeradio or gradio or xmms with the FMRadio plug−in.
