KNOWN PROBLEMS:
+about preemphasis:
+ You can set the preemphasis for radio by the following command:
+ #v4l2-ctl -d /dev/radio0 --set-ctrl=pre_emphasis_settings=1
-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.
+ "pre_emphasis_settings=1" means that you select the 50us. If you want
+ to select the 75us, please use "pre_emphasis_settings=2"
- 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
-
