Abstract
The invention relates to the transmission of files in a digital broadcasting system, particularly in a DAB system according to the standard ETS 300 401. According to the invention, a file descriptor (16) is created for each file. This file descriptor is of the data group type denoted by 0011 in said standard and includes parameters (27) describing the file associated with the descriptor. The file descriptor is transmitted in the broadcasting system before the file and possibly also during the transmission of the file. The information to be transmitted is divided into segments, which are identified in a file-specifically unique manner, such as consecutive numbering, which starts from zero at the beginning of each file.
