+TESTED APPLICATIONS:
+
+-VLC1.0.4 test the video and dvb. The GUI is friendly to use.
+
+-Mplayer test the video.
+
+-Mplayer test the FM. The mplayer should be compiled with --enable-radio and
+	 --enable-radio-capture.
+	The command runs as this(The alsa audio registers to card 1):
+	#mplayer radio://103.7/capture/ -radio adevice=hw=1,0:arate=48000 \
+		-rawaudio rate=48000:channels=2
+
+---------------------------------------------------------------------------
+KNOWN PROBLEMS:
+
+country code
+	- The firmware of the chip needs the country code to determine
+	the stardards of video and audio when it runs for analog TV or radio.
+	The DVB-T does not need the country code.
+
+	So you must set the country-code correctly. The V4L2 does not have
+	the interface,the driver has to provide a parameter `country_code'.
+
+	You could set the coutry code in two ways, take USA as example
+	(The USA's country code is 1):
+
+	[1] add the following line in /etc/modprobe.conf before you insert the
+	    card into USB hub's port :
+		poseidon country_code=1
+
+	[2] You can also modify the parameter at runtime (before you run the
+	    application such as VLC)
+		#echo 1 > /sys/module/poseidon/parameter/country_code
