0. NEWS:
+ 2004-01-13 - moved the mirrored pid_filter_table back to dvb-dibusb
+ - first almost working version for HanfTek UMT-010
+ - found out, that Yakumo/HAMA/Typhoon are predessors of the HanfTek
+ 2004-01-10 - refactoring completed, now everything is very delightful
+ - tuner quirks for some weird devices (Artec T1 AN2235 device has sometimes a
+ Panasonic Tuner assembled). Tunerprobing implemented. Thanks a lot to Gunnar Wittich.
+ 2004-12-29 - after several days of struggling around bug of no returning URBs fixed.
+ 2004-12-26 - refactored the dibusb-driver, splitted into separate files
+ - i2c-probing enabled
2004-12-06 - possibility for demod i2c-address probing
- new usb IDs (Compro,Artec)
2004-11-23 - merged changes from DiB3000MC_ver2.1
1. How to use?
NOTE: This driver was developed using Linux 2.6.6.,
-it is working with 2.6.7, 2.6.8.1, 2.6.9 .
+it is working with 2.6.7 and above.
Linux 2.4.x support is not planned, but patches are very welcome.
NOTE: I'm using Debian testing, so the following explaination (especially
the hotplug-path) needn't match your system, but probably it will :).
+The driver is included in the kernel since Linux 2.6.10.
+
1.1. Firmware
The USB driver needs to download a firmware to start working.
first have a look, which debug level are available:
modinfo dib3000mb
+modinfo dib3000-common
+modinfo dib3000mc
modinfo dvb-dibusb
+modprobe dib3000-common debug=<level>
modprobe dib3000mb debug=<level>
+modprobe dib3000mc debug=<level>
modprobe dvb-dibusb debug=<level>
should do the trick.
At this point you should be able to start a dvb-capable application. For myself
I used mplayer, dvbscan, tzap and kaxtv, they are working. Using the device
-as a slave device in vdr, was not working for me. Some work has to be done
-(patches and comments are very welcome).
+in vdr (at least the USB2.0 one) is working.
2. Known problems and bugs
-TODO:
-- signal-quality and strength calculations
+- none this time
2.1. Adding support for devices
maximum bandwidth of about 5-6 MBit/s when connected to a USB2.0 hub.
This is not enough for receiving the complete transport stream of a
DVB-T channel (which can be about 16 MBit/s). Normally this is not a
-problem, if you only want to watch TV, but watching a channel while
-recording another channel on the same frequency simply does not work.
-This applies to all USB1.1 DVB-T devices.
+problem, if you only want to watch TV (this does not apply for HDTV),
+but watching a channel while recording another channel on the same
+frequency simply does not work. This applies to all USB1.1 DVB-T
+devices, not only dibusb)
A special problem of the dibusb for the USB1.1 is, that the USB control
IC has a problem with write accesses while having MPEG2-streaming
these features is maybe a solution. Additionally this behaviour of VDR exceeds
the USB1.1 bandwidth.
+Update:
+For the USB1.1 and VDR some work has been done (patches and comments are still
+very welcome). Maybe the problem is solved in the meantime because I now use
+the dmx_sw_filter function instead of dmx_sw_filter_packet. I hope the
+linux-dvb software filter is able to get the best of the garbled TS.

2.3. Comments
Patches, comments and suggestions are very very welcome
