Abstract (en)
The present invention relates to a data packet structure defining a data packet of predetermined length for the transmission of a data stream in a digital audio broadcasting system, such as DAB or DRM. Further the present invention provides methods for transmitting and receiving packets using the data packet structure, as well as a corresponding transmitter and receiver. Moreover the present invention provides a digital broadcasting system using the data packet structure. To increase the number of data packets of which undamaged data can be derived under identical reception condition the present invention introduces additional error control coding for a packet based digital audio broadcasting transport mechanism. The proposed solution provides a fully back-wards compatible way i.e. does not require any changes to conventional receivers, to reconstruct application data from even erroneously received data packets, <IMAGE>
