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
44:
1.19 ! js 45: Note: Some of the drivers will refuse to load and spit out
! 46: error messages if they cannot find their hardware. You can
! 47: ignore them, or edit insmod.sh and comment out drivers that
! 48: you don't need.
! 49:
! 50: You will have to load at least two drivers:
! 51: - one for the main DVB card / device
! 52: - one for the frontend (i.e. tuner + demodulator)
! 53:
1.17 js 54:
55: Detailed instructions for building:
56: -----------------------------------
1.1 hunold 57:
1.10 holger 58: If you encounter any problems while executing the follwing steps please read
59: the TROUBLESHOOTING file.
1.8 holger 60:
1.10 holger 61: Simply type 'make' to build the driver. The compiled modules will be located
1.11 holger 62: in directory ./build-2.4/ or ./build-2.6/, depening on the kernel version you
1.8 holger 63: are running. There you will also find scripts to load and unload the modules.
64:
1.15 hunold 65: For some cards or frontends you need to download additional firmware
66: binaries:
67:
68: - dvb-ttpci: http://www.linuxtv.org/download/dvb/
69: => wget http://www.linuxtv.org/download/dvb/dvb-ttpci-01.fw
70: Place the "dvb-ttpci-01.fw" file in the build-2.4 and/or build-2.6
71: directory. The firmware will be compiled into the driver at it used to
72: be.
73:
74: - alps_tdlb7:
75: This driver needs a copy of the firmware file 'Sc_main.mc' from the
76: Haupauge windows driver in the '/usr/lib/hotplug/firmware' directory.
77: Alternatively, you can also pass the complete filename with the module
78: parameter 'firmware_file'.
79:
80: - tda1004x:
81: This driver needs a copy of the DLL "ttlcdacc.dll" from the Haupauge or
82: Technotrend windows driver saved as
83: '/usr/lib/hotplug/firmware/tda1004x.mc'. You can also pass the complete
84: file name with the module parameter 'tda1004x_firmware'.
1.16 hunold 85: Currently the DLL from v2.15a of the technotrend driver is supported.
86: Other versions can be added reasonably painlessly.
1.15 hunold 87: Windows driver URL: http://www.technotrend.de/
88:
89: - ttusb-dec:
90: see "ttusb-dec.txt" in linux/Documentation for details
91:
92: If something is missing, you get notified in the build process or when
93: loading the modules.
1.8 holger 94:
1.16 hunold 95: Just in case you are wondering: the "alps_bsrv2" driver is gone, please use
96: the new "ves1x93" driver instead.
97:
1.10 holger 98: In ./build-2.4/ or ./build-2.6/ you find the insmod script.
99:
1.9 holger 100: Use './insmod.sh load' to load the driver modules, './insmod.sh unload' to
101: remove them. './insmod debug' loads the drivers with debugging enabled.
1.13 holger 102: These scripts load all drivers for all cards but the ones based on the bt8xx.
103: For bt8xx based cards please use the insmod-bt8xx.sh script instead.
1.10 holger 104:
1.12 holger 105: Now check the klog and syslog (in doubt type 'dmesg') for error messages.
1.9 holger 106:
1.8 holger 107: When you reached this point successfully you probably want to start some
108: test applications, download the linuxtv-dvb-apps-1.1.tar.gz package, unpack
109: it and compile it. This package contains some tools to test and debug the
110: driver:
111:
1.9 holger 112: linuxtv-dvb-apps-1.1/apps/szap/ contains three simple applications called
113: szap, czap and tzap for zapping with DVB-S, DVB-C or DVB-T cards.
114: Read linuxtv-dvb-apps-1.1/apps/szap/ README for usage instructions.
1.8 holger 115:
116: Note 1: tuning succeeded if you see the FE_HAS_LOCK flag and "status 1f"; a
117: good signal has a low bit error rate (ber) and zero uncorrectable packets (unc).
118:
119: Note 2: you must keep ?zap running, or the frontend will go to sleep (unless
120: you load dvb-core.o with dvb_shutdown_timeout=0)
121:
122: If your card has a hardware MPEG decoder you can watch TV with xawtv (together
123: with e.g. szap for DVB tuning); Note: xawtv cannot control the DVB tuner, you
124: must use ?zap
125:
126: For cards without hardware MPEG decoder you need a software MPEG decoder,
127: e.g. mplayer or xine (you need *very* recent versions which understand MPEG2
128: transport streams; xine v0.9.21 and mplayer dev-CVS-030723-16:39-3.3.1 seem to
129: work); Note: You must run ?zap with the -r flag to enable stream output to the
130: dvr device, and keep it running while watching tv.
131:
132: Examples:
133: mplayer - < /dev/dvb/adapter0/dvr0
134: xine stdin://mpeg2 < /dev/dvb/adapter0/dvr0
135:
136: Note: Newest mplayer and xine versions are reported to have builtin DVB support
1.9 holger 137: (see ./linux/Documentation/dvb/faq.txt for more info).
1.8 holger 138:
139: For 'real' everyday use you probably don't want to use these test applications
1.9 holger 140: but install a program like VDR or MythTV.
141: (Read ./linux/Documentation/dvb/faq.txt for some links)
1.8 holger 142:
1.10 holger 143: When everything is working you probably want to install the driver on your
144: system by typing 'make install'. If you want to load the modules automatically
145: when an application tries to open the device you need to add lines like these
146: to your modules.conf:
147:
148: probeall /dev/dvb dvb-ttpci
149: alias /dev/dvb/* /dev/dvb
150: below dvb-ttpci alps_bsrv2 alps_tdmb7 alps_tdlb7
151: add below dvb-ttpci grundig_29504-401 grundig_29504-491
152: add below dvb-ttpci stv0299 ves1820
153:
154: Note: this example is for people with Technotrend-based PCI cards, they must
155: load the dvb-ttpci driver and a matching frontend drivers that are potentially
156: used on these cards. In order to find out which ones are required for your
157: setup check the lsmod output after loading the driver like described above.
158: Those DVB modules that have a usecount greater zero are required in your
159: setup - edit the modules.conf file appropriatly]
160:
161: Debian users don't edit modules.conf manually but add the lines above to a new
162: file in /etc/modutils/ (e.g. /etc/modutils/dvb) and call 'update-modules' then.
163:
1.8 holger 164: --------------------------------------------------------------------------------
165:
166: The build system has been tested down to 2.4.20, if you run an older kernel
167: either update your kernel or just try - maybe you need to add some tweaks in
168: the dvb_compat.[hc] files. Please report your modifications on the linux-dvb
169: mailing list.
170:
171: If you want to build a not-standalone driver but want to patch your 2.6 kernel
172: source tree with this driver please read README-2.6.
173:
174: More documentation is located in ./linux/Documentation/dvb/.
175:
176: good luck,
