1.17 js 3:
1.23 ! hunold 4: Digital Video Broadcast drivers for Linux 2.6.x.
1.17 js 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:
1.23 ! hunold 9: The DVB drivers are already included in Linux 2.6.x, so you usually
! 10: don't need this package. What you will need, hwoever, is firmware.
! 11: see below.
1.17 js 12:
13: Quick start:
14: ------------
15:
16: 1. Get firmware:
1.18 js 17:
1.17 js 18: Some DVB cards need firmware to operate. Due to licensing problems
19: we won't distribute the firmware binaries with the driver source,
20: you must get them seperately. See below for details about where
21: to get and where to put.
1.18 js 22:
23: For Linux 2.6.x also see linux/Documentation/dvb/firmware.txt and
24: linux/Documentation/firmware_class/README.
25:
1.23 ! hunold 26: 2. cd build-2.6
1.17 js 27:
28: 3. make
29:
30: 4. ./insmod.sh load
31:
1.19 js 32: Note: Some of the drivers will refuse to load and spit out
33: error messages if they cannot find their hardware. You can
34: ignore them, or edit insmod.sh and comment out drivers that
35: you don't need.
36:
37: You will have to load at least two drivers:
38: - one for the main DVB card / device
39: - one for the frontend (i.e. tuner + demodulator)
40:
1.17 js 41:
42: Detailed instructions for building:
43: -----------------------------------
1.1 hunold 44:
1.10 holger 45: If you encounter any problems while executing the follwing steps please read
46: the TROUBLESHOOTING file.
1.8 holger 47:
1.10 holger 48: Simply type 'make' to build the driver. The compiled modules will be located
1.23 ! hunold 49: in directory ./build-2.6/, depening on the kernel version you
1.8 holger 50: are running. There you will also find scripts to load and unload the modules.
51:
1.15 hunold 52: For some cards or frontends you need to download additional firmware
53: binaries:
54:
55: - dvb-ttpci: http://www.linuxtv.org/download/dvb/
56: => wget http://www.linuxtv.org/download/dvb/dvb-ttpci-01.fw
1.23 ! hunold 57: Place the "dvb-ttpci-01.fw" file in the build-2.6
1.15 hunold 58: directory. The firmware will be compiled into the driver at it used to
59: be.
60:
61: - alps_tdlb7:
62: This driver needs a copy of the firmware file 'Sc_main.mc' from the
63: Haupauge windows driver in the '/usr/lib/hotplug/firmware' directory.
64: Alternatively, you can also pass the complete filename with the module
65: parameter 'firmware_file'.
66:
67: - tda1004x:
68: This driver needs a copy of the DLL "ttlcdacc.dll" from the Haupauge or
69: Technotrend windows driver saved as
1.21 quincy 70: '/usr/lib/hotplug/firmware/tda1004x.bin'. You can also pass the complete
1.15 hunold 71: file name with the module parameter 'tda1004x_firmware'.
1.21 quincy 72: Currently the DLL from v2.15a, or 2.16a of the technotrend PCI driver is supported.
73: Please note, even if you're using a USB device, you _must_ get the
74: file from the TechnoTrend PCI driver.
1.15 hunold 75: Windows driver URL: http://www.technotrend.de/
76:
77: - ttusb-dec:
78: see "ttusb-dec.txt" in linux/Documentation for details
79:
80: If something is missing, you get notified in the build process or when
81: loading the modules.
1.8 holger 82:
1.16 hunold 83: Just in case you are wondering: the "alps_bsrv2" driver is gone, please use
84: the new "ves1x93" driver instead.
85:
1.23 ! hunold 86: In ./build-2.6/ you find the insmod script.
1.10 holger 87:
1.9 holger 88: Use './insmod.sh load' to load the driver modules, './insmod.sh unload' to
89: remove them. './insmod debug' loads the drivers with debugging enabled.
1.13 holger 90: These scripts load all drivers for all cards but the ones based on the bt8xx.
91: For bt8xx based cards please use the insmod-bt8xx.sh script instead.
1.10 holger 92:
1.12 holger 93: Now check the klog and syslog (in doubt type 'dmesg') for error messages.
1.9 holger 94:
1.8 holger 95: When you reached this point successfully you probably want to start some
96: test applications, download the linuxtv-dvb-apps-1.1.tar.gz package, unpack
97: it and compile it. This package contains some tools to test and debug the
98: driver:
99:
1.9 holger 100: linuxtv-dvb-apps-1.1/apps/szap/ contains three simple applications called
101: szap, czap and tzap for zapping with DVB-S, DVB-C or DVB-T cards.
102: Read linuxtv-dvb-apps-1.1/apps/szap/ README for usage instructions.
1.8 holger 103:
104: Note 1: tuning succeeded if you see the FE_HAS_LOCK flag and "status 1f"; a
105: good signal has a low bit error rate (ber) and zero uncorrectable packets (unc).
106:
107: Note 2: you must keep ?zap running, or the frontend will go to sleep (unless
108: you load dvb-core.o with dvb_shutdown_timeout=0)
109:
110: If your card has a hardware MPEG decoder you can watch TV with xawtv (together
111: with e.g. szap for DVB tuning); Note: xawtv cannot control the DVB tuner, you
112: must use ?zap
113:
114: For cards without hardware MPEG decoder you need a software MPEG decoder,
115: e.g. mplayer or xine (you need *very* recent versions which understand MPEG2
116: transport streams; xine v0.9.21 and mplayer dev-CVS-030723-16:39-3.3.1 seem to
117: work); Note: You must run ?zap with the -r flag to enable stream output to the
118: dvr device, and keep it running while watching tv.
119:
120: Examples:
121: mplayer - < /dev/dvb/adapter0/dvr0
122: xine stdin://mpeg2 < /dev/dvb/adapter0/dvr0
123:
124: Note: Newest mplayer and xine versions are reported to have builtin DVB support
1.9 holger 125: (see ./linux/Documentation/dvb/faq.txt for more info).
1.8 holger 126:
127: For 'real' everyday use you probably don't want to use these test applications
1.9 holger 128: but install a program like VDR or MythTV.
129: (Read ./linux/Documentation/dvb/faq.txt for some links)
1.8 holger 130:
1.10 holger 131: When everything is working you probably want to install the driver on your
132: system by typing 'make install'. If you want to load the modules automatically
133: when an application tries to open the device you need to add lines like these
134: to your modules.conf:
135:
136: probeall /dev/dvb dvb-ttpci
137: alias /dev/dvb/* /dev/dvb
138: below dvb-ttpci alps_bsrv2 alps_tdmb7 alps_tdlb7
139: add below dvb-ttpci grundig_29504-401 grundig_29504-491
140: add below dvb-ttpci stv0299 ves1820
141:
142: Note: this example is for people with Technotrend-based PCI cards, they must
143: load the dvb-ttpci driver and a matching frontend drivers that are potentially
144: used on these cards. In order to find out which ones are required for your
145: setup check the lsmod output after loading the driver like described above.
146: Those DVB modules that have a usecount greater zero are required in your
147: setup - edit the modules.conf file appropriatly]
148:
149: Debian users don't edit modules.conf manually but add the lines above to a new
150: file in /etc/modutils/ (e.g. /etc/modutils/dvb) and call 'update-modules' then.
151:
1.8 holger 152: --------------------------------------------------------------------------------

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.
