How to use? +NOTE: This driver was developed using Linux 2.6.6., +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. + +You can either use "get_dvb_firmware dibusb" to download the firmware or you +can get it directly via + +for USB1.1 (AN2135) +http://www.linuxtv.org/downloads/firmware/dvb-dibusb-5.0.0.11.fw + +for USB1.1 (AN2235) (a few Artec T1 devices) +http://www.linuxtv.org/downloads/firmware/dvb-dibusb-an2235-1.fw + +for USB2.0 (FX2) Hauppauge, DiBcom +http://www.linuxtv.org/downloads/firmware/dvb-dibusb-6.0.0.5.fw + +for USB2.0 ADSTech/Kworld USB2.0 +http://www.linuxtv.org/downloads/firmware/dvb-dibusb-adstech-usb2-1.fw + +for USB2.0 HanfTek +http://www.linuxtv.org/downloads/firmware/dvb-dibusb-an2235-1.fw + + +1.2. Compiling + +Since the driver is in the linux kernel, activating the driver in +your favorite config-environment should sufficient. I recommend +to compile the driver as module. Hotplug does the rest. + +1.3. Loading the drivers + +Hotplug is able to load the driver, when it is needed (because you plugged +in the device). + +If you want to enable debug output, you have to load the driver manually and +from withing the dvb-kernel cvs repository. + +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. + +When the driver is loaded successfully, the firmware file was in +the right place and the device is connected, the "Power"-LED should be +turned on. + +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 +in vdr is working now also. + +2. Known problems and bugs + +- Don't remove the USB device while running an DVB application, your system will die. + +2.1. Adding support for devices + +It is not possible to determine the range of devices based on the DiBcom +reference designs. This is because the reference design of DiBcom can be sold +to thirds, without telling DiBcom (so done with the Twinhan VP7041 and +the HAMA device). + +When you think you have a device like this and the driver does not recognizes it, +please send the ****load*.inf and the ****cap*.inf of the Windows driver to me. + +Sometimes the Vendor or Product ID is identical to the ones of Twinhan, even +though it is not a Twinhan device (e.g. HAMA), then please send me the name +of the device. I will add it to this list in order to make this clear to +others. + +If you are familar with C you can also add the VID and PID of the device to +the dvb-dibusb-core.c-file and create a patch and send it over to me or to +the linux-dvb mailing list, _after_ you have tried compiling and modprobing +it. + +2.2. USB1.1 Bandwidth limitation + +Most of the currently supported devices are USB1.1 and thus they have a +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 (this does not apply for HDTV), +but watching a channel while recording another channel on the same +frequency simply does not work very well. This applies to all USB1.1 +DVB-T devices, not just dibusb) + +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. + +The bug, where the TS is distorted by a heavy usage of the device is gone +definitely. All dibusb-devices I was using (Twinhan, Kworld, DiBcom) are +working like charm now with VDR. Sometimes I even was able to record a channel +and watch another one. + +2.3. Comments + +Patches, comments and suggestions are very very welcome. + +3. Acknowledgements + Amaury Demol (ademol@dibcom.fr) and Francois Kanounnikoff from DiBcom for + providing specs, code and help, on which the dvb-dibusb, dib3000mb and + dib3000mc are based. + + David Matthews for identifying a new device type (Artec T1 with AN2235) + and for extending dibusb with remote control event handling. Thank you. + + Alex Woods for frequently answering question about usb and dvb + stuff, a big thank you. + + Bernd Wagner for helping with huge bug reports and discussions. + + Gunnar Wittich and Joachim von Caron for their trust for giving me + root-shells on their machines to implement support for new devices. + + Some guys on the linux-dvb mailing list for encouraging me + + Peter Schildmann >peter.schildmann-nospam-at-web.de< for his + user-level firmware loader, which saves a lot of time + (when writing the vp7041 driver) + + Ulf Hermenau for helping me out with traditional chinese. + + André Smoktun and Christian Frömmel for supporting me with + hardware and listening to my problems very patient |
