* 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.
