Annotation of dvb-kernel/README, revision 1.18
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:
1.18 ! js 25:
1.17 js 26: Some DVB cards need firmware to operate. Due to licensing problems
27: we won't distribute the firmware binaries with the driver source,
28: you must get them seperately. See below for details about where
29: to get and where to put.
1.18 ! js 30:
! 31: For Linux 2.6.x also see linux/Documentation/dvb/firmware.txt and
! 32: linux/Documentation/firmware_class/README.
! 33:
! 34: Note: The firmware loader has been backported from 2.6 to 2.4.24,
! 35: but the drivers do not yet support this. You must compile the
! 36: firmwares into the drivers.
! 37:
1.17 js 38:
39: 2. cd build-2.4 or build-2.6
40:
41: 3. make
42:
43: 4. ./insmod.sh load

46: Detailed instructions for building:
47: -----------------------------------
1.1 hunold 48:
1.10 holger 49: If you encounter any problems while executing the follwing steps please read
50: the TROUBLESHOOTING file.
1.8 holger 51:
1.10 holger 52: Simply type 'make' to build the driver. The compiled modules will be located
1.11 holger 53: in directory ./build-2.4/ or ./build-2.6/, depening on the kernel version you
1.8 holger 54: are running. There you will also find scripts to load and unload the modules.
55:
1.15 hunold 56: For some cards or frontends you need to download additional firmware
57: binaries:
58:
59: - dvb-ttpci: http://www.linuxtv.org/download/dvb/
60: => wget http://www.linuxtv.org/download/dvb/dvb-ttpci-01.fw
61: Place the "dvb-ttpci-01.fw" file in the build-2.4 and/or build-2.6
62: directory. The firmware will be compiled into the driver at it used to
63: be.
64:
65: - alps_tdlb7:
66: This driver needs a copy of the firmware file 'Sc_main.mc' from the
67: Haupauge windows driver in the '/usr/lib/hotplug/firmware' directory.
68: Alternatively, you can also pass the complete filename with the module
69: parameter 'firmware_file'.
70:
71: - tda1004x:
72: This driver needs a copy of the DLL "ttlcdacc.dll" from the Haupauge or
73: Technotrend windows driver saved as
74: '/usr/lib/hotplug/firmware/tda1004x.mc'. You can also pass the complete
75: file name with the module parameter 'tda1004x_firmware'.
1.16 hunold 76: Currently the DLL from v2.15a of the technotrend driver is supported.
77: Other versions can be added reasonably painlessly.
1.15 hunold 78: Windows driver URL: http://www.technotrend.de/
79:
80: - ttusb-dec:
81: see "ttusb-dec.txt" in linux/Documentation for details
82:
83: If something is missing, you get notified in the build process or when
84: loading the modules.
1.8 holger 85:
1.16 hunold 86: Just in case you are wondering: the "alps_bsrv2" driver is gone, please use
87: the new "ves1x93" driver instead.
88:
1.10 holger 89: In ./build-2.4/ or ./build-2.6/ you find the insmod script.
90:
1.9 holger 91: Use './insmod.sh load' to load the driver modules, './insmod.sh unload' to
92: remove them. './insmod debug' loads the drivers with debugging enabled.
1.13 holger 93: These scripts load all drivers for all cards but the ones based on the bt8xx.
94: For bt8xx based cards please use the insmod-bt8xx.sh script instead.
1.10 holger 95:
1.12 holger 96: Now check the klog and syslog (in doubt type 'dmesg') for error messages.
1.9 holger 97:
1.8 holger 98: When you reached this point successfully you probably want to start some
99: test applications, download the linuxtv-dvb-apps-1.1.tar.gz package, unpack
100: it and compile it. This package contains some tools to test and debug the
101: driver:
102:
1.9 holger 103: linuxtv-dvb-apps-1.1/apps/szap/ contains three simple applications called
104: szap, czap and tzap for zapping with DVB-S, DVB-C or DVB-T cards.
105: Read linuxtv-dvb-apps-1.1/apps/szap/ README for usage instructions.
1.8 holger 106:
107: Note 1: tuning succeeded if you see the FE_HAS_LOCK flag and "status 1f"; a
108: good signal has a low bit error rate (ber) and zero uncorrectable packets (unc).
109:
110: Note 2: you must keep ?zap running, or the frontend will go to sleep (unless
111: you load dvb-core.o with dvb_shutdown_timeout=0)
112:
113: If your card has a hardware MPEG decoder you can watch TV with xawtv (together
114: with e.g. szap for DVB tuning); Note: xawtv cannot control the DVB tuner, you
115: must use ?zap
116:
117: For cards without hardware MPEG decoder you need a software MPEG decoder,
118: e.g. mplayer or xine (you need *very* recent versions which understand MPEG2
119: transport streams; xine v0.9.21 and mplayer dev-CVS-030723-16:39-3.3.1 seem to
120: work); Note: You must run ?zap with the -r flag to enable stream output to the
121: dvr device, and keep it running while watching tv.
122:
123: Examples:
124: mplayer - < /dev/dvb/adapter0/dvr0
125: xine stdin://mpeg2 < /dev/dvb/adapter0/dvr0
126:
127: Note: Newest mplayer and xine versions are reported to have builtin DVB support
1.9 holger 128: (see ./linux/Documentation/dvb/faq.txt for more info).
1.8 holger 129:
130: For 'real' everyday use you probably don't want to use these test applications
1.9 holger 131: but install a program like VDR or MythTV.
132: (Read ./linux/Documentation/dvb/faq.txt for some links)
1.8 holger 133:
1.10 holger 134: When everything is working you probably want to install the driver on your
135: system by typing 'make install'. If you want to load the modules automatically
136: when an application tries to open the device you need to add lines like these
137: to your modules.conf:
138:
139: probeall /dev/dvb dvb-ttpci
140: alias /dev/dvb/* /dev/dvb
141: below dvb-ttpci alps_bsrv2 alps_tdmb7 alps_tdlb7
142: add below dvb-ttpci grundig_29504-401 grundig_29504-491
143: add below dvb-ttpci stv0299 ves1820
144:
145: Note: this example is for people with Technotrend-based PCI cards, they must
146: load the dvb-ttpci driver and a matching frontend drivers that are potentially
147: used on these cards. In order to find out which ones are required for your
148: setup check the lsmod output after loading the driver like described above.
149: Those DVB modules that have a usecount greater zero are required in your
150: setup - edit the modules.conf file appropriatly]
151:
152: Debian users don't edit modules.conf manually but add the lines above to a new
153: file in /etc/modutils/ (e.g. /etc/modutils/dvb) and call 'update-modules' then.
154:
1.8 holger 155: --------------------------------------------------------------------------------
156:
157: The build system has been tested down to 2.4.20, if you run an older kernel
158: either update your kernel or just try - maybe you need to add some tweaks in
159: the dvb_compat.[hc] files. Please report your modifications on the linux-dvb
160: mailing list.
161:
162: If you want to build a not-standalone driver but want to patch your 2.6 kernel
163: source tree with this driver please read README-2.6.
164:
165: More documentation is located in ./linux/Documentation/dvb/.
166:
167: good luck,
