+	You can set the preemphasis for radio by the following command:
+	#v4l2-ctl -d /dev/radio0 --set-ctrl=pre_emphasis_settings=1

+	"pre_emphasis_settings=1" means that you select the 50us. If you want

-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
-
-	The known country codes show below:
