|

* 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.
