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.
