Detailed Description

The libdvbv5 API works with a set of key/value properties. There are two types of properties:
- The ones defined at the Kernel's frontent API, that are found at /usr/include/linux/dvb/frontend.h (actually, it uses a local copy of that file, stored at ./include/linux/dvb/frontend.h)
- Some extra properties used by libdvbv5. Those can be found at lib/include/libdvbv5/dvb-v5-std.h and start at DTV_USER_COMMAND_START.
Just like the DTV properties, the stats are cached. That warrants that all stats are got at the same time, when dvb_fe_get_stats() is called.
