* 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.

|
||||
* There are basically two types of files used for DVB:
|
||||
* - files that describe the physical channels (also called as transponders);
|
||||
* - files that describe the several programs found on a MPEG-TS (also called
|
||||
* as zap files).
|
||||
*
|
||||
* The libdvbv5 library defines an unified type for both types. Other
|
||||
* applications generally use different formats.
|
||||
*
|
||||
* The purpose of the functions and structures defined herein is to provide
|
||||
* support to read and write to those different formats.
