+tlg2300 release notes
+====================
+
+This is a v4l2/dvb device driver for the tlg2300 chip.
+
+
+current status
+==============
+
+video
+ - support mmap and read().(no overlay)
+
+audio
+ - The driver will register a ALSA card for the audio input.
+
+vbi
+ - Works for almost TV norms.
+
+dvb-t
+ - works for DVB-T
+
+FM
+ - Works for radio.
+
+---------------------------------------------------------------------------
+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
+
+ The known country codes show below:
