1.17 ! js 1: linuxtv-dvb-1.1.0
! 2: =================
! 3:
! 4: Digital Video Broadcast drivers for Linux 2.4.19+ and Linux 2.6.x.
! 5:
! 6: Note: Unlike in previous releases, the test/utility programs have
! 7: been unbundled and are released seperately as linuxtv-dvb-apps-1.1.0.
! 8:
! 9:
! 10: Linux 2.6.x:
! 11: The DVB drivers are already included in Linux 2.6.x, so you usually
! 12: don't need this package. What you will need, hwoever, is firmware.
! 13: see below.
! 14:
! 15: Linux 2.4.19+:
! 16: Due to changes in the video2linux layer we don't support kernels
! 17: older than 2.4.19. If you need to use an older kernel you must
! 18: apply video4linux patches to the kernel first.
! 19:
! 20:
! 21: Quick start:
! 22: ------------
! 23:
! 24: 1. Get firmware:
! 25: Some DVB cards need firmware to operate. Due to licensing problems
! 26: we won't distribute the firmware binaries with the driver source,
! 27: you must get them seperately. See below for details about where
! 28: to get and where to put.
! 29: For Linux 2.6.x and 2.4.24+ also see linux/Documentation/dvb/firmware.txt.
! 30:
! 31: 2. cd build-2.4 or build-2.6
! 32:
! 33: 3. make
! 34:
! 35: 4. ./insmod.sh load
! 36:
! 37:
! 38: Detailed instructions for building:
! 39: -----------------------------------
1.1 hunold 40:
1.10 holger 41: If you encounter any problems while executing the follwing steps please read
42: the TROUBLESHOOTING file.
1.8 holger 43:
1.10 holger 44: Simply type 'make' to build the driver. The compiled modules will be located
1.11 holger 45: in directory ./build-2.4/ or ./build-2.6/, depening on the kernel version you
1.8 holger 46: are running. There you will also find scripts to load and unload the modules.
47:
1.15 hunold 48: For some cards or frontends you need to download additional firmware
49: binaries:
50:
51: - dvb-ttpci: http://www.linuxtv.org/download/dvb/
52: => wget http://www.linuxtv.org/download/dvb/dvb-ttpci-01.fw
53: Place the "dvb-ttpci-01.fw" file in the build-2.4 and/or build-2.6
54: directory. The firmware will be compiled into the driver at it used to
55: be.
56:
57: - alps_tdlb7:
58: This driver needs a copy of the firmware file 'Sc_main.mc' from the
59: Haupauge windows driver in the '/usr/lib/hotplug/firmware' directory.
60: Alternatively, you can also pass the complete filename with the module
61: parameter 'firmware_file'.
62:
63: - tda1004x:
64: This driver needs a copy of the DLL "ttlcdacc.dll" from the Haupauge or
65: Technotrend windows driver saved as
66: '/usr/lib/hotplug/firmware/tda1004x.mc'. You can also pass the complete
67: file name with the module parameter 'tda1004x_firmware'.
1.16 hunold 68: Currently the DLL from v2.15a of the technotrend driver is supported.
69: Other versions can be added reasonably painlessly.
1.15 hunold 70: Windows driver URL: http://www.technotrend.de/
71:
72: - ttusb-dec:
73: see "ttusb-dec.txt" in linux/Documentation for details
74:
75: If something is missing, you get notified in the build process or when
76: loading the modules.
1.8 holger 77:
1.16 hunold 78: Just in case you are wondering: the "alps_bsrv2" driver is gone, please use
79: the new "ves1x93" driver instead.
80:
1.10 holger 81: In ./build-2.4/ or ./build-2.6/ you find the insmod script.
82:
1.9 holger 83: Use './insmod.sh load' to load the driver modules, './insmod.sh unload' to
84: remove them. './insmod debug' loads the drivers with debugging enabled.
1.13 holger 85: These scripts load all drivers for all cards but the ones based on the bt8xx.
86: For bt8xx based cards please use the insmod-bt8xx.sh script instead.
1.10 holger 87:
1.12 holger 88: Now check the klog and syslog (in doubt type 'dmesg') for error messages.
1.9 holger 89:
1.8 holger 90: When you reached this point successfully you probably want to start some
91: test applications, download the linuxtv-dvb-apps-1.1.tar.gz package, unpack
92: it and compile it. This package contains some tools to test and debug the
93: driver:
94:
1.9 holger 95: linuxtv-dvb-apps-1.1/apps/szap/ contains three simple applications called
96: szap, czap and tzap for zapping with DVB-S, DVB-C or DVB-T cards.
97: Read linuxtv-dvb-apps-1.1/apps/szap/ README for usage instructions.
1.8 holger 98:
99: Note 1: tuning succeeded if you see the FE_HAS_LOCK flag and "status 1f"; a
100: good signal has a low bit error rate (ber) and zero uncorrectable packets (unc).
101:
102: Note 2: you must keep ?zap running, or the frontend will go to sleep (unless
103: you load dvb-core.o with dvb_shutdown_timeout=0)
104:
105: If your card has a hardware MPEG decoder you can watch TV with xawtv (together
106: with e.g. szap for DVB tuning); Note: xawtv cannot control the DVB tuner, you
107: must use ?zap
108:
109: For cards without hardware MPEG decoder you need a software MPEG decoder,
110: e.g. mplayer or xine (you need *very* recent versions which understand MPEG2
111: transport streams; xine v0.9.21 and mplayer dev-CVS-030723-16:39-3.3.1 seem to
112: work); Note: You must run ?zap with the -r flag to enable stream output to the
113: dvr device, and keep it running while watching tv.
114:
115: Examples:
116: mplayer - < /dev/dvb/adapter0/dvr0
117: xine stdin://mpeg2 < /dev/dvb/adapter0/dvr0
118:
119: Note: Newest mplayer and xine versions are reported to have builtin DVB support
1.9 holger 120: (see ./linux/Documentation/dvb/faq.txt for more info).
1.8 holger 121:
122: For 'real' everyday use you probably don't want to use these test applications
1.9 holger 123: but install a program like VDR or MythTV.
124: (Read ./linux/Documentation/dvb/faq.txt for some links)
1.8 holger 125:
1.10 holger 126: When everything is working you probably want to install the driver on your
127: system by typing 'make install'. If you want to load the modules automatically
128: when an application tries to open the device you need to add lines like these
129: to your modules.conf:
130:
131: probeall /dev/dvb dvb-ttpci
132: alias /dev/dvb/* /dev/dvb
133: below dvb-ttpci alps_bsrv2 alps_tdmb7 alps_tdlb7
134: add below dvb-ttpci grundig_29504-401 grundig_29504-491
135: add below dvb-ttpci stv0299 ves1820
136:
137: Note: this example is for people with Technotrend-based PCI cards, they must
138: load the dvb-ttpci driver and a matching frontend drivers that are potentially
139: used on these cards. In order to find out which ones are required for your
140: setup check the lsmod output after loading the driver like described above.
141: Those DVB modules that have a usecount greater zero are required in your
142: setup - edit the modules.conf file appropriatly]
143:
144: Debian users don't edit modules.conf manually but add the lines above to a new
145: file in /etc/modutils/ (e.g. /etc/modutils/dvb) and call 'update-modules' then.
146:
1.8 holger 147: --------------------------------------------------------------------------------
148:
149: The build system has been tested down to 2.4.20, if you run an older kernel
150: either update your kernel or just try - maybe you need to add some tweaks in
151: the dvb_compat.[hc] files. Please report your modifications on the linux-dvb
152: mailing list.
153:
154: If you want to build a not-standalone driver but want to patch your 2.6 kernel
155: source tree with this driver please read README-2.6.
156:
157: More documentation is located in ./linux/Documentation/dvb/.
158:
159: good luck,
