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 + + The known country codes show below: + country code : country + 93 "Afghanistan" + 355 "Albania" + 213 "Algeria" + 684 "American Samoa" + 376 "Andorra" + 244 "Angola" + 54 "Argentina" + 374 "Armenia" + 61 "Australia" + 43 "Austria" + 994 "Azerbaijan" + 973 "Bahrain" + 880 "Bangladesh" + 375 "Belarus" + 32 "Belgium" + 501 "Belize" + 229 "Benin" + 591 "Bolivia" + 387 "Bosnia and Herzegovina" + 267 "Botswana" + 55 "Brazil" + 673 "Brunei Darussalam" + 359 "Bulgalia" + 226 "Burkina Faso" + 257 "Burundi" + 237 "Cameroon" + 1 "Canada" + 236 "Central African Republic" + 235 "Chad" + 56 "Chile" + 86 "China" + 57 "Colombia" + 242 "Congo" + 243 "Congo, Dem.
