+Hi,
+
+this is a utility to setup IR control keymaps using the /proc/av7110_ir 
+interface.
+
+just call 
+
+   # ./av7110_loadkeys [-i|--invert] [-a|--address <num>] keymapname.(rc5|rcmm) > /proc/av7110_ir
+
+If your IR receiver hardware inverts the signal, you should use the -i 
+or --invert command line option.
+
+If you have two or more devices which use the same IR protocol, you should
+specify the -a or --address parameter. If the parameter is omitted, the
+driver listens to all device addresses. Some examples:
+
+Listen to *any* IR transmitter with uses the RC5 protocol:
+# ./av7110_loadkeys hauppauge.rc5 > /proc/av7110_ir
+
+Listen to RC5 transmitter with address 2:
+# ./av7110_loadkeys -a 2 hauppauge.rc5 > /proc/av7110_ir
+
+If you don't know the correct value for the -a parameter, take a look
+on the debug output of the driver (see below).
+
+Now you can test your hardware setup using evtest
+
+   # ./evtest /dev/input/eventX
+
+where eventX is the IR input event device, usually event0 if you don't
+use USB mice or keyboards.
+
+------------------------------------------------------------------------
+
+Keymaps are in format:
+
+   <key> <associated input keycode>
+
+   0x00   KEY_0
+   0x01   KEY_1
+   0x42   KEY_HOME
+
+------------------------------------------------------------------------
+
+In order to write a new keymap you might want to see the raw key 
+values in the kernel log. Use
+
+   # insmod dvb-ttpci.o av7110_ir_debug=1
+
+in order to enable some verbosity in the av7110_ir driver. Then watch
+the kernel log while pressing your remote control keys. When you don't see
+any messages in your kernel log you should check all electrical connections,
+the selected protocol (RC5 or RCMM?) and the inversion setting.
+
+You find a list of all linux input key identifiers in </usr/include/input.h> 
+and "./input_fake.h".
+
+Please post new keymaps on the linux-dvb mailing list or send them to 
+me <holger@convergence.de>.
+
+have fun! 
+
+Holger

+Hi,
+
+this is a little channel scan utility to generate szap/tzap/czap compatible 
+channel lists. Scan does not do a frequency scan, however, so you must
+manually provide the data for tuning to one or more start transponders.
+A number of initial-tuning-data files are provided for various dvb-c, dvb-s
+and dvb-t networks around the world. If you make a new one feel free to
+submit it to the linux-dvb mailing list http://linuxtv.org/mailinglists.xml.
+
+Basic usage: ./scan dvb-s/Astra-19.2E | tee mychannels.conf
+
+If you want it to check a specific frequency, tune to that frequency 
+(e.g. using szap/tzap/czap) and then use './scan -c'.
+
+For more scan options see ./scan -h.
+
+Good luck,
+Holger + Johannes

+Hi,
+
+this are some trivial zapping applications explaining how to use the frontend
+and demux API. They are also pretty useful to test your hardware.
+
+For DVB-S, Astra Channel config file:
+
+$ ./szap -c channels.conf-dvbs-astra n24
+
+will tune to N24. For DVB-C, Berlin Cable channel config:
+
+$ ./czap -c channels.conf-dvbc-berlin Arte
+
+For DVB-T, Berlin Config:
+
+$ ./czap -c channels.conf-dvbt-berlin phoenix
+
+By default the MPEG stream is routed to a hardware decoder. If you want to 
+record the stream to disk you will route it to the DVR device by using the 
+'-r' option:
+
+$ ./czap -c channels.conf-dvbt-berlin phoenix -r
+[keep it running in one console]
+$ cat /dev/dvr/adapter0/dvr0 > /tmp/recording.ts
+[in a second console, will dump the MPEG transport stream to /tmp/recording.ts]
+
+The status messages have the following meaning:
+
+status 0x1f              --- The demodulator status bits.
+			      0x1f means all bits set, everything ok.
+
+signal [0x0000...0xffff] --- Signal Strength. Values above 0x8000 should be ok.
+
+snr [0x0000...0xffff]    --- Signal/Noise Ratio. Values above 0x8000 are ok.
+
+ber [0...0xffffffff]     --- Bit Error Rate. The less the better.
+
+unc [0...0xffffffff]     --- Number of Uncorrectable Blocks.
+			     Small numbers are Preferable.
+
+If everything is alright and all frontend circuits are working stable 
+(are locked) you should see a FE_HAS_LOCK in the rightmost line.
+
+Good luck,
+
+Holger

+/* szap -- simple zapping tool for the Linux DVB API
+ *
+ * szap operates on VDR (http://www.cadsoft.de/people/kls/vdr/index.htm)
+ * satellite channel lists (e.g. from http://www.dxandy.de/cgi-bin/dvbchan.pl).
+ * szap assumes you have a "Universal LNB" (i.e. with LOFs 9750/10600 MHz).
+ *
+ * Compilation: `gcc -Wall -I../../ost/include -O2 szap.c -o szap`
+ *  or, if your DVB driver is in the kernel source tree:
+ *              `gcc -Wall -DDVB_IN_KERNEL -O2 szap.c -o szap`

+Hello,
+
+In theory the driver could be made to send the DEC the reset sequence when
+all devices were closed.  However, due to the awkwardness of switching
+between slave and stand-alone mode, I've decided against this.  Hence this
+application, which I hope provides the user a nice compromise between
+control and ease-of-use.
+
+ttusb_dec_reset is a small utility for resetting a ttusb-dec device to
+stand-alone mode after use.  It requires libusb, which can be found here:
+
+http://libusb.sourceforge.net/
+
+There is probably a package for it included with your linux distribution
+though.
+
+For the utility to reset a device, it must have permission to access the usb
+device, and the device must not be claimed by anything else.  That means that
+the ttusb-dec module must be rmmoded before using this utility.  You probably
+want to have turned off any hotplug mechanisms before running the utility
+or the device will likely get taken over again once it comes back up.  Or you
+could just yank the usb cable out.
+
+The utility takes no arguments, you just run it:
+./ttusb_dec_reset
+
+Cheers,
+Alex
